The one who was relatively calm was classmate Pan Shihua. After seeing classmate Xie wearing new clothes today, he thanked his classmate in advance for making relevant preparations.
Several teachers from the National Association were a little nervous and were dissatisfied with Zhang Huayao for actually doing this.
Vice President Bi cleared his throat: cough cough.
Fu Xinheng looked back.
Xie Wanying caught Teacher Fu's look.
Don't think that Mr. Fu is a cold person, but he takes the overall situation into consideration when it comes to certain issues. On the contrary, he is more cautious and does not act like a reckless hero like Mr. Zhang.
If you don't want to answer, no one will blame you. If you want to answer - this is the meaning of what Teacher Fu said to her.
If she doesn't answer now and becomes a coward, wouldn't Teacher Fu like Classmate Pan more? From this point of view, the opportunity given by Zhang must be seized. She took out the new clothes and wore them like this today, which is also considered a risk.
Without hesitation, she stood up.
The teachers present at the scene had already blinked when Zhang Huayao called out. They did not expect that what Zhang Huayao said before was not a joke and he really asked students to answer questions.
Seeing her standing up, she did not refuse to answer, and all the experts present were stunned for a moment: What could a student say?
When pairs of eyes were shining like spotlights, Xie Wanying's straight Mandarin voice came out of her lips: "I think, first of all, this material is not up to standard."
Huh~ This classmate Xie deserves to be the most honest person. Zhang Huayao narrowed his eyes.
In fact, the big guys are all doubting this, but they can't defeat the people of other manufacturers for a while. Now, let's see how Mr.
The message saved his old mother.
Others continued to wait, waiting for her to further explain her definition.
After all, the manufacturer couldn't hold it back anymore and refuted her first: "Our products can only leave the factory after passing the test through experience."
"What I said was that it failed the customer's requirements, not that the product was unqualified." Xie Wanying corrected.
There is a slight difference between being unqualified and not passing the test. It is true that some manufacturers like to use qualified products as an excuse to avoid product responsibilities, which is a headache. The so-called qualified products are generally only benchmarked against domestic industry requirements. Failure to pass can mean that they cannot meet the customer requirements.
The requirements of a group of clinicians. Everyone knows that the standard compliance line of the latter far exceeds the former. The establishment or revision of relevant standards in China is far behind the actual standards, some for several years. Among medical consumables, why do clinicians prefer
Use foreign products because some domestic manufacturers can only provide qualified products.
The people from the manufacturer were choked by her words.
After hearing what she said, the teachers present's eyes twinkled: Hey, this student seems to have some talent?
"The structure of artificial blood vessels made of foreign ePTFE can be seen under a microscope, with micropores and very well controlled pore spacing. This is reflected in the fact that when it is implanted into an organism, its own tissue will grow into the gaps to form a strong
The inner and outer membranes. This is very important to ensure the patency of artificial blood vessels and prevent blood leakage." Xie Wanying said.
"You mean the structure under an electron microscope? Our manufacturer must have done inspections in this area." The person from the manufacturer replied, "Our aperture can reach 30 microns."
The manufacturer who said this sounded a bit proud and complacent at the end. You know, this aperture technology is very difficult to pass.
