The ignition source is a pyrotechnic igniter with a total energy of 10 kilojoules. The ignition source ignites the gas mixture with a lag time of 0.6 seconds. The ignition agent has a mass of 2.4 grams and is composed of 40% aluminum powder, 30% barium nitrate and 30%
Composed of barium peroxide.
The ignition source is ignited by an electric ignition head, and the ignition source is located at the geometric center of the explosion chamber. A pressure sensor is installed on the wall of the explosion chamber to measure the explosion pressure, and the pressure sensor is connected to the recorder.
Formulated steps: Put the gas sample into the propagation container and pressurize it to 2.0 MPa with compressed air; evacuate the pipeline to a certain vacuum state to ensure that the explosion chamber is under atmospheric pressure when ignited; start the pressure recorder and turn on the propagation
The valve of the container is delayed to ignite the ignition source, and the explosion pressure is recorded and measured; after each experiment, the explosion chamber must be blown out with air to obtain the explosion pressure and pressure rise rate.
Preliminary determination of the maximum pressure rise rate of the gas mixture: kx is less than 20 MPameter per second; or is less than or equal to 20 MPameter per second and is greater than or equal to 30 MPameter per second; KX is greater than 30 MPameter per second.
As long as it is within this range, gas transmission can affect all air-breathing creatures in this underground fortress. In the laboratory, the old man watched the young man's series of operations with fear, and he couldn't help but voice his doubts——
“What if this doesn’t work?”
"Generally, reactions can be divided into two categories: simple reactions and complex reactions. Simple reactions can be divided into single-molecule reactions, bipartite reactions and trimolecular reactions. The so-called single-molecule reaction means that only one molecule participates in the reaction process.
Reaction. A bimolecular reaction is a reaction in which two molecules of the same type or different types collide. A trimolecular reaction is a reaction in which three molecules of the same type or different types collide with each other. Since the probability of a three-molecule collision is very small, so
The reaction rate is extremely slow."
"The previous gas distorted the reaction process of one molecule during the final cell division, thus making the nerve center of these things unable to accommodate the second order. Here I have downplayed the analytical formula of the first molecule. These things
After receiving the secondary splitting of these gases, the nerve center will create redundancy. You use the spread of influence to issue orders, and these things will respect you as their master after hearing your voice."
After hearing this, the old man turned the devil's valve again without any hesitation.
The previous turning of the valve turned tens of thousands of soldiers into devils in hell. This time, he will turn them into his minions. In fact, from the first time he sold his soul to the "general",
He knew that this day would come sooner or later, and he would say a long goodbye to the best things in the world forever.
Farewell, my moonsong, my breath, my day, my golden day, my fire.
But he was very happy that when he was on the verge of death, he could always wake up in time; as soon as the war broke out, he immediately turned over to the side he liked. At this moment, his heart spread its sails to the fading wind, and wanted to go wherever it was.
Go to the Island of Shade——
Running like a musk deer in the forest, mad for its scent.../There is nothing for it to sing about,/Even the berries on the hedges have been damaged by frost or eaten by other birds.
But high up, / Alone, I welcome another day of hunger. / The olive trees are all white, facing the strong wind - / Like white-haired people hunched over to fight, / Their branches are like grapevines, / Unloaded
The bucket is filled with heavy burdens, and inside, there is red foam and golden foam, which are left in midsummer——
God often uses the eyes of clouds to cry for everything he created.
The distribution of explosion overpressure with axial distance shows a trend of first rising rapidly, then slowly attenuating, and finally rising again near the closed end. The gas fluctuation reaction near the pipeline has just begun, and the pressure is low. 0.5 to 1.5 in the pipeline
The presence of a 1-meter-long obstacle between meters causes flow, expands the reaction surface, stimulates a strong chemical reaction, and accelerates the gas peak surface, which is very close to the shock wave speed, so the peak overpressure rises rapidly.
When the gas leaves the obstacle area, the timing pointer from the valve accelerates and weakens, and the speed also begins to decrease. As the amount of gas increases, the reaction time of the gas increases, and the acceleration time of the shock wave increases, so the attenuation speed increases with the amount of gas.
Slow down, when the gas reaches 4.5 meters, the gas volume is the largest, and the peak overpressure decays the slowest.
"laugh--"
When the shock wave reaches the closed end of the pipeline, reflection occurs. Near the closed end of the pipeline, the two-way shock waves work together to cause a secondary pressure increase. Since both ends of the pipeline are closed, the shock wave will be reflected when propagating in the pipeline, so the pressure will oscillate and secondary pressure will occur.
Sub-overpressure. The closer to the closed end of the pipeline, the more obvious the pressure oscillation phenomenon will be.
Through the closed laboratory glass, the old man saw the clamoring zombies outside. After the gas overflowed, they began to slowly fall silent. The decayed light in his eyes slowly turned turbid, as if there was a girl in a white skirt among them.
The soft gaze revealed for a moment was like the sister who once weaved bamboo dragonflies for herself on the hillside where poppies were in full bloom.
"sister--"
Is it you?/I want to rely on the loose curly hair,/Every Aegean Sea wind is chasing it,/I want to rely on the eyes with long eyelashes,/the eyelashes kiss your pink cheeks,/I want to
With those eyes like wild deer, I swear, /You are my life, I love you.
"sister--"
After becoming the soldiers of the "Jade Broken Project" and being transformed, their appearance will stop aging, and they will be permanently fixed at the moment of thought death, achieving the so-called "immortality". But why, why do you contribute to my country?
, but my sister can’t come back?
It seems that you only fell temporarily on the cliff, but did not fall off the cliff. However, my favorite relatives can no longer come back from the hillside with the poppies in full bloom in my memory, with their skirts flowing gracefully.
There was no sound on the bridge, / only the returning herds were wandering staggeringly... / only the footsteps of his lover, / never slow to roar into his heart. / Occasionally, there was a rustling sound——
/ There was a little squirrel jumping on the treetop. / It jumped on the pine branch, / trampled a piece of snow on Dalia's body, / Dalia stood there
Standing,/frozen in the dream of boundless magic.
We may not be able to get together for many years, we may never see each other again forever, why are you silent.
"laugh--"
The gas is still discharged outward, and obvious secondary overpressure appears at axial distances of 6.525 meters, 7.525 meters, and 8.275 meters. The closer to the closed end of the pipeline, the more obvious the pressure oscillation phenomenon. As the gas volume decreases, the shock wave velocity gradually
Attenuation. Since the amount of gas will affect the time of the chemical reaction, the greater the amount of gas, the longer the chemical reaction will last, the longer the acceleration time for the shock wave, and the greater the shock wave speed will be.
Therefore, the more gas there is, the greater the severity of the shock wave. At the same time, the difference in shock wave speed in the later stage is very small. In this section, since the initial gas volume is the same, under the action of the shock wave, the gas volume and foaminess in this section will change.
The changes are not big.
From the 1 meter position, the shock wave speeds of different gas amounts begin to be significantly different. In the 1 to 2.25 meter section, 2.5 meters, 3.5 meters, and 4.5 meters long gas amounts, this section is filled with gas, so these three gas amounts
The difference in shock wave velocity is still not large, but when the gas volume is 1.5 meters long, there is only gas in part of this section. Obviously the chemical reaction in this section is very short, the acceleration of the chemical reaction is obviously weakened, and the shock wave speed will be significantly smaller.
.
Countless gases were exuding from the small holes in the pipes. The girl in the white dress standing among the corpses looked at him for a moment with a solemn face, filled with sincere joy.
The old man's hands pressed on the glass, almost breaking the glass, tears welling up in his eyes - it was her, it must be her. She was his sister!
We stayed on the porch at night, looking up at the dark shadows under the eaves, watching the cool moon appear and disappear under the clouds, and the stars appearing and disappearing. The moonlight fell softly on your face. In this lonely evening, covered with fog and rain, I was here
I feel its sigh in my new loneliness.
On my lapel remains the fragrance of the lotus played by your sculls when you were swimming, / on your sleeves are your tears of joy, your sleepy lips, / and the shadow of a mallow flower under the moon, / which I secretly caught when you closed your eyes.
The yellow bergamot on the chest emits an ancient light fragrance from the flexed fingers; / the red begonia blooms in the corner of the mossy stepstone, / like autumn tears dripping quietly; /
On the exquisite water-absorbing rockery in the fish tank, / the red color of the back of the Pu'er grass leaf is turned; / in front of the small courtyard, there is a small tea-colored armchair - / once supported my arm in the past.
My sister——
The peach is ripe, but already rotten. It is still hanging tremblingly on the tree, leaving its vivid memory to future generations.
"Notes on the Book of Han": "Moon Order" - In the month of mid-spring, rain begins and the peach flowers begin to bloom. When the peach blossoms bloom, there is rain, the rivers and valleys are icy, the crowds gather, and the waves are long, so it is called peach blossom.
Water. Twenty-four flower trade winds, starting from plum blossoms and ending with neem.
It turns out that no matter how beautiful things are, they will eventually pass away, and my sister has been buried on the cliff for a long time on the hillside where the poppies are in full bloom. Even if she did not die at the beginning, after I turned the valve of hell that killed tens of thousands of soldiers.
, and took the initiative to throw himself into the arms of death.
When Romeo died in his arms, Romeo once said - Dear Juliet, why are you still so beautiful?
Could it be that the void of death, that skinny and abominable monster, is also a passionate seed, so he hides you in this dark cave to be his mistress? In order to prevent such a thing, I will always accompany you and never leave this long journey.
The palace of long nights; here I will stay, with your maids, the maggots; ah! here I will rest for ever, and shake off the bonds of misfortune from my world-weary mortal body. Eyes, look at you
The last look!
Arms, embrace you for the last time! Lips, ah! Portal of your breath, with a legal kiss, make an everlasting contract with all-encompassing death! Come, guide of bitterness, pilot of despair, now
Hurry up and crash your ship, tired of the wind and waves, against the rock! For my love, I drank this drink! I died in this kiss.
Confession is an unsinkable ship.
Buried in the belly of a fish, and my soul fed to the devil.
The obstacle suddenly accelerates the gas turbulence, and the increased reaction surface intensifies the chemical reaction, causing the shock wave speed to increase rapidly. After 2.25 meters, the impact of the obstacle on the shock wave is very small, and only the deflagration of the gas itself accelerates the shock wave.
The acceleration effect is significantly weakened, so the shock wave velocity begins to gradually decay.
At the very end, the maximum value of the shock wave velocity all appears after the maximum explosion peak pressure, and the reaction is more violent. The maximum pressure rise rate has the same change trend along the axial distance, which shows that it first increases rapidly and then gradually decays. At the end
Under the action of obstacles, the gas end flow intensifies and the chemical reaction becomes more violent.
Outside the obstacle area, there is no acceleration effect of the obstacle, only the acceleration effect caused by the deflagration of the gas itself, and the maximum pressure rise rate begins to decrease. When the shock wave reaches the closed end of the pipeline, under the action of the closed end, the shock wave is reflected
, the maximum pressure rise rate increased again.
"laugh--"
The last gas seemed to be lingering and stubbornly resisting, disappearing into the air.
The second poison gas projection was completed. But he couldn't be happy.
People often undergo this transformation when they are dying, and even tigers will lick the cross.
There was no strange color in the eyes of the girl in the white dress, only empty spaces. The glass door of the laboratory was opened, and the old man stepped forward and gently stroked the girl's face. These things would not attack him now, but -
-It's just that the girl in front of him is not his sister - but he has found the direction of his soul. The old man held the girl gently in his arms and couldn't help but sigh.
My love for you is not in vain.
"Dear God" - If you really exist, please teach me how to hide this feeling that I never know how to express. But neither bombs nor my broken heart can stop me from walking barefoot
Together with you, we will walk through the Champ de Mars, which is full of jasmine flowers in June. Although the scenery of my hometown is no longer there, I am willing to accompany you to spend the few years and days I have left.
Why did the flower wither?/My passionate love pressed it to my heart, so the flower withered./Why did the string break?/I played a syllable that it couldn't overcome, so the string broke.
I did not raise my hands in vain to seek something other than hope, nor did I crush joy into dust to squeeze out the wine of pain.
The light shines under the frowning clouds, like a beaten child, with tears stained on his gray face. The wind howls, like the cry of a wounded world, but I know that I am trudging to meet you.
There are pearls in the sea, and there are stars in the sky, but in my heart, my heart, my heart, only you will be left in the future——
"What you said before is the first thing. What is the second thing you need me to help you accomplish?" The current group of corpses can no longer attack me. In this underground fortress, I am the same as
Yu became the king here - owning the strongest castle in the world, countless servants, and my sister who was resurrected from the dead.
The young man watched everything that happened in front of him calmly, without any overestimation of what kind of tangle the girl in white had had with this man in the past, but the words he spoke were earth-shattering.
"If you don't succeed in killing them, I need you to bring him a message."
"hehe--"
The old man touched the woman's face in a subtle way and smiled, "Now all the zombies here obey my orders, why should I obey your orders?"
"I can make you live with just one thought, and I can also make you die with just one thought. Do you really want to go against me?"
The old man turned around, and tens of thousands of zombies were standing behind him, ready to attack. With just one command, they could tear this terrifying, almost demonic young man to pieces. However, in the young man's fearless light,
, but ultimately chose not to do that.
"What message do you want me to bring?"
"I need you to tell him - or them -" the young man opened his mouth slightly, and calmly said something that sounded almost heavenly to the old man. After finishing speaking, the young man pushed aside the corpses, and under the old man's eyes,
and walked out.
"Why? Why can't you tell him yourself since you have such great ability?" The old man shouted at his retreating back.
"I can't - because 'those people' are looking at me too closely, and more importantly -" a sigh, "I have discovered in Fan Li's golden treasure that he is him." How can I return this?
How can he hide a word in the world with such great means? As long as he is somewhere within reach, he cannot hide a person or a word anywhere.
Only in this invisible deep underground can he leave a complete message, and he guarantees his absolute safety. In return, the old man needs to do these two favors for himself.
Although twenty years later, it is very likely that "he" will still organize the best Snow Leopard commandos in his organization to kidnap another self, but this time, this time he is fully prepared, making
This sentence will only be known by the designated target, not "him".
This is the reason why he has published so many mazes in the Tomb of King Guangling, Fangla Underground Palace, and even Fan Li’s Jinzang: Since you have powerful means, the entire country can be used by you, and the entire country’s resources can be used by you.
If you tilt, then the underground that you cannot see is my layout and plan.
The man's back disappeared from sight, and apart from the fluttering words left in the air, there seemed to be no trace of his existence.
But if anyone who sets foot in this area 20 years later can see this scene, they will fall into huge shock and self-doubt: this young man is none other than the Snow Leopard Assault who has disappeared for nearly 20 years.
Non-team staff——Li Reform.
Li Lvyan's throat was dry and he struggled, "What we saw from the beginning to the end was not an illusion, but this space, which is a huge illusion!"
The power of these words shocked all three of them.
"Shit Beetle, what are you talking about? You just found the angle and played with the beauty for a long time, and then you said this?" I thought being trapped in the illusion was bad enough, what else could it be?
Worse than that? Answer: Li Green Ant’s bullshit.
In fact, when Li Luyi decided to do this experiment, everyone was in favor of it. The situation was already very bad, so there was no harm in trying it. Even if the experiment failed, the worst he could do was still be trapped in the illusion and unable to get out. What else could happen?
Bad? It turns out that there is only worse, not the worst.
The original idea is to try, but the result is that if you try, you will die.
"I know this handsome boy. You were just chiseling the wall to enjoy the sunshine. You didn't care about my handsome boy's life and death at all!" The next project is to add a pot lid to the Pacific Ocean; or to build the Great Wall.
Take the tiling project! But these are big projects. If you want to do something small, just give the ants gold teeth.
If you think the project is too small and not challenging, you can also make an insulating shell for the sun, wrap it up, or install a runway for the equator, or install an elevator for the Himalayas.
So that chestnut-breasted cloud room has not achieved the effect of boiling water to boil the Yellow Sea, nor has it achieved the achievement of fragrant fragrance floating around the equator several times - how about shouting at whoring pigs? Wogua is very angry, and his work has been in vain.
——
Black Glasses was the wisest, "Anyway, now that we know what our situation is, it's already a great achievement -" Looking at Li Lvyan, "Do you have a way to break this situation?"
Li Lvyan hesitated for a long time: Actually, he had an idea, but he was afraid that like before, he would fall short and not be of any help in the end. Instead, he would cause a lot of new troubles, so he didn't dare to speak.
"There is a way, but I'm afraid -"
Black Glasses said calmly, "If you have any ideas, just do it boldly. If anything happens here, she and I will be here and we won't hurt you."
This sentence was like a reassurance, and it instantly opened up Li Luyi's Rendu and Dumai channels, and he nodded fiercely.
