Wang Cuiju accidentally said what was on her mind.
When she heard her daughter's words, she thought that it was right. Her daughter could engage in scientific research and generate income for the country at the age of fourteen. She has done a lot of things in recent years. Although she didn't understand it, but seeing how much the old man and the old man attached great importance to it, she must have
not simple.
"Yes, my daughter is not an ordinary person, she is a genius!"
Liu Qianqian chuckled, "Mom, I'm hungry, please cook me something delicious!"
"Okay, today is your big day when you join the company, I will cook you more delicious food!"
Liu Qianqian nodded with a smile, "Mom, I want to eat the braised pork and braised pork ribs you made!"
"Do it, do it, do it, your mother who loves to eat will do it for you!" Another foodie girl, Wang Cuiju is still acceptable. Who makes this foodie girl so awesome?
"Thank you, mother!"
...
"Dr. Liu, do you need help?"
Liu Qianqian shook her head, "No need, thank you!"
Although the man was a little disappointed when he saw this, he was particularly impressed when he saw Dr. Liu conducting experiments so seriously. Especially when he saw the experiments in Liu Qianqian's hands, there were no mistakes and they were perfect. He admired Liu Qianqian even more.
Sure enough, the boss is the boss.
"Any thing else?"
The man smiled awkwardly and said, "I have a few questions to ask you. Do you have time?"
Liu Qianqian took off the gloves on her hands, nodded, and looked at her watch, "There are still fifteen minutes left for get off work, so I'll give you fifteen minutes, is that enough?"
The man nodded, "Enough, enough!"
The man handed over the scientific research materials in his hand. He made detailed records on them. At first glance, he looked like a diligent and studious child. Liu Qianqian nodded in her heart. It was not just a show of force.
"You don't understand here?"
"kindness!"
"The tap secret equation should be used here, you can also use..., and here, you can try to change a material, I think cadmium is good..."
"Yes, I understand, I understand, okay, I understand, yes, yes!"
"Okay, that's it for today!"
"Okay, thank you Dr. Liu!"
Liu Qianqian shook her head, "You can try to combine different materials and use the calculation equation just now, you should get different results!"
"Thank you Dr. Liu!"
Liu Qianqian nodded and left the laboratory. As soon as Liu Qianqian left, others gathered around her.
"Liu Xiaofang, you can do it. How dare you ask Dr. Liu questions? You're awesome!"
"Liu Xiaofang, do you have other intentions?"
"Xiao Fang, how are you? Is Dr. Liu as hard to contact and aloof as the rumors say?"
Liu Xiaofang looked at his colleagues around him in confusion and shook his head, "Dr. Liu is very good. Every question she talks about is very thorough and to the point. Dr. Liu has a very good attitude. Have you misunderstood something? As for the intention, Liu
Doctor is the goddess in my mind, how dare I have any other intentions!"
Liu Qianqian was ready to go home after finishing her day's work, but on the way she met Mr. Zhou who came to see her. Liu Qianqian respected Mr. Zhou very much, so naturally she couldn't leave Mr. Zhou to go home alone.
"Sissi, I have encountered a problem here. Please help me see if there is a solution!"
Liu Qianqian nodded and followed Zhou Maolin. After arriving at the office, Liu Qianqian found out that Mr. Zhou gave her a piece of information on car engines. At present, there is no own engine in China, and they basically rely on imports from abroad.
, Liu Qianqian really hadn’t considered this aspect before, but after looking at the above data and performance, Liu Qianqian shook her head, this engine didn’t seem to be ideal.
An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc.
The information in Liu Qianqian's hand was about an internal combustion engine, but a lot of the data on it was wrong. Liu Qianqian looked at Mr. Zhou, "Didn't you find that there was something wrong with the data on it?"
Mr. Zhou nodded, "As you can see, we have been studying for half a year, but we still can't get the correct method. Later, we speculated backwards and found that the data was different. Afterwards, we made some modifications. Take a look at these data!
"
Liu Qianqian nodded and looked at the data. The data above was correct, but there were still many limitations.
"Have you ever thought about using electric engines?"
"Motor generator?"
"It's an electric car!"
Zhou Maolin was stunned for a moment and seemed unable to react, "Electric cars? We have also made ideas, but many things cannot be realized. It is very difficult!"
Compared with fuel vehicles, the main differences between pure electric vehicles are four major components: drive motor, speed controller, power battery, and vehicle charger.
The speed and starting speed of a pure electric vehicle depend on the power and performance of the drive motor. The length of its driving range depends on the capacity of the vehicle's power battery. The weight of the vehicle's power battery depends on the type of power battery such as lead-acid.
, zinc-carbon, lithium batteries, etc., their volumes, specific gravity, specific power, specific energy, and cycle life are all different.
The drive motors of pure electric vehicles include DC brush, brushless, permanent magnet, electromagnetic, and AC stepper motors. Their selection is also related to the vehicle configuration, purpose, and grade.
In addition, the speed control of the drive motor can also be divided into step speed control and stepless speed control. There are electronic speed control controllers and no speed control controllers. The motors include hub motors, inner rotor motors, and single motor drives.
Multi-motor drive and combined motor drive, etc.
Liu Qianqian talked a lot eloquently, and Zhou Maolin's eyes became brighter and brighter. If they can really develop an electric car, it will not only have an independent engine, but also protect the environment. This is definitely the best choice, but their current
It seems that automotive technology is not up to par!
"You don't have to worry about technical issues, I can provide them for you, you just need to prepare the materials and manpower!"
"real?"
Zhou Maolin's eyes lit up, astonishingly bright. Liu Qianqian nodded, "Tomorrow I will compile a document for you on the core technology of electric vehicles. You can do experiments first. I still have some experiments in hand. After I finish my work, I will
Go find you!"
"Okay, let's do it!"
Zhou Maolin is not impulsive, but has absolute confidence in Liu Qianqian. So far, nothing Liu Qianqian has said or done has been unsuccessful, and they don't know how many things Liu Qianqian has in her mind.
But they knew that Liu Qianqian had mastered all the books in the National Library, and once any information was included in it, the higher-ups would prepare a copy for Liu Qianqian, which was enough to show how much the higher-ups valued this little girl.
What Liu Qianqian was busy with was none other than nutritional supplements. She was doing this because her brother was going to go on a mission abroad in a few days. She was afraid that Liu Qinghe would not be used to foreign food, and dry food was not nutritious.
I could barely fill my stomach, so I thought of nutritional supplements.
