Chapter 1950 High-quality and low-priced new technology
For those who have developed good working and study habits, as long as they are on the right track, the step-by-step daily routine of entering the process will be a accumulation of time and money for them. The process is not difficult.
So Zhou Zhi’s main job now is to deal with the challenges brought by new business. To put it bluntly, it is to help Mai Xiaomiao establish a work management model.
Mai Xiaomiao is a person who is accustomed to working alone and is a "brain knight". His strength is conquering unknown areas in the ocean of mathematical knowledge, but he is not strong in managing subordinate teams in the real world.
And with her image and personality, she is not suitable for management positions.
However, in Zhou Zhi's words, Mai Xiaomiao's charm is enough to conquer people who are good at engineering management, such as himself, Hu Tianyu and others. In the four-leaf clover's workplace ethics, the charm of engineering managers is actually less than that of technical experts. Charm, and the charm of a technical guru is less than the charm of a theoretical guru.
Zhou Zhi does not want to correct this phenomenon of "not treating the CEO as a cadre". On the contrary, he believes that in companies that are dominated by technology, this should be a characteristic that companies should have.
So even though he was trying to attack Mai Xiaomiao, Zhou Zhi was happy with it.
As a result, the pair achieved very impressive results. Originally, Mai Mingdong was quite dissatisfied with his granddaughter following Zhou Zhi to the remote countryside, but now that the results were there, he could not find any reason to object. , it’s hard to say anything more.
“You said you’ve been hanging out with a little girl recently?” Even Liu Liangzhen, who always only talks about work, started gossiping: “You have become a subject leader at a young age. It’s really a powerful alliance. , when will you bring it to grandma to see?”
Zhou Zhi is struggling with alcohol lamps, test tubes, culture media, and potato germs. This is a required course in biotechnology. First, a large number of samples with the same genes and traits must be obtained, which is called a "strain" in academic terms. After having a strain, Only then can we apply different stimuli to the samples, study the effects of these different stimulus conditions on biological individuals with the same genes, and thereby screen out useful conditions.
For animals, the cultivation of this strain is a very difficult process, because according to people's common concept, through continuous inbreeding, "purified genes" can be obtained, and the genes of the offspring will be Become unified and stable.
However, this is a double-edged sword, because the genetic defects of individuals bred in this way will be equally solidified or even amplified. In the end, these individuals will have various genetic problems and lose the ability to continue the family line. "ability.
It was not until 1913 that American researchers studying cancer successfully bred an animal strain that was adaptable to inbreeding purification and had strong reproductive capabilities. This strain of experimental animals is still widely used today. Here, this is the BALB/c mouse, also commonly known as the "white mouse".
With the introduction of mice, many biomedical technologies have achieved rapid progress.
For plant scientific research, this approach also has the same value. The only advantage is that plants, especially plants in closed areas, have very high genetic similarities between different plants and are very stable. After screening, they are then supplemented. With the cultivation methods of modern science and technology, it will soon be possible to replicate a large number of experimental samples of the same strain for use in scientific research experiments.
What Zhou Zhi is doing now is the basic work of agricultural science and technology, the expansion of strains. Dissolve the nutrients in water, add gelatin, pour the melted gelatin into the petri dish, remove the germ from the sterilized potato, place the germ on top of the gelatin with tweezers sterilized by an alcohol lamp, and cover it The lid of the petri dish allows the germs to germinate safely under sterile and interference-free conditions, and then turn into plants.
Such a plant is extremely fragile like a strain of mouse, so it also needs a strengthening process. Generally speaking, the seedlings are carried out one stage at a time. The cultivation and cultivation conditions also become more extensive step by step, so that the fragile seedlings gradually turn into strong plants, which can eventually bloom and bear fruit, and then enter the next round of expanded reproduction.
So some necessary agricultural technologies must be introduced into this process, such as mulch technology and greenhouse technology.
Zhou Zhi once gave Liu Liangzhen an idea, which was to change the color of the mulch film to black. This has many benefits. First, black absorbs heat, which can make the ground temperature higher than ordinary mulch films; secondly, it can isolate light, except for the openings. Except for planting seedlings, other wild grasses in the field cannot survive due to lack of light, so that the purpose of "harmless weeding" can be achieved.
Liu Liangzhen thought this was a good idea. Together with Zhou Zhi, they asked the mulch manufacturer in the autonomous prefecture about this idea. As a result, the manufacturer said that the work was too simple for us, and there were just too many plastic mulch manufacturers. It's just a matter of adding black emulsifier.
Then a factory technician also made a suggestion. Since the purpose of the black mulch film is to increase the ground temperature, if your funds allow, we can actually make a total reflective covering film for fun.
Zhou Zhi is dumbfounded. Although you are responsible for part of the production of aerospace materials, you can't just open your mouth and do it, right? Total reflection, no energy loss, doesn't sound like it conforms to the laws of physics.
The technician laughed and said that Mr. Zhou might be studying liberal arts, right? The phenomenon of total reflection is an optical phenomenon, and of course it also has an effect on the spread of heat radiation. The production method is not as complicated as Mr. Zhou imagined.
The so-called total reflection actually means that when light enters a medium with a lower refractive index from a medium with a higher refractive index, if the incident angle is greater than a certain critical angle, the refracted light will disappear and all incident light will be reflected. without entering the low refractive index medium.
Zhou Zhi suddenly slapped his forehead. The optical fiber in signal propagation technology uses this principle for lossless transmission. How could he forget it at this moment? !
There is no need for technicians to explain in detail next. The so-called total reflection mulch does not mean that it will reflect all the geothermal heat back. It is made using the principle of total reflection. An inner layer is sprayed on the mulch. This inner layer The refractive index of the earth layer is higher than that of the outer layer. The heat radiated from the earth exists in all directions. When they encounter such a mulch, all the geothermal heat with an incident angle greater than the critical angle will be reflected back, so that it is quite Slows down the loss of geothermal heat to a certain extent.
Equivalent to the black outer layer opening up and the high refractive index inner layer throttling, the heat preservation efficiency is improved.
Viewed from a certain visual angle, the inner layer of such a mulch film will have a metallic reflection effect, but in fact it is useless at all. It is purely a physical phenomenon created by the superposition of different transparent materials.
The cost is not as high as Zhou Zhi imagined. At least for the Academy of Agricultural Sciences, it is high quality and low price.
