Lu Donglai asked what everyone present wanted to ask.

There is no way, it is really Bai Yi's previous statement that is too shocking, so shocking that even a veteran of the battlefield like the head of armaments, who is accustomed to seeing bloody storms, is a little dumbfounded.

Britain applied germanium elements to radar during World War II, and after the war, more advanced germanium diodes were used in it.

In particular, the inflexible situation of being on combat readiness duty on the southeast coast to defend against the invasion of foreign fighters on the mainland has made the radar officers and men in charge of front-line vigilance very distressed.

In particular, after raising their own level of electronic warfare, foreign hostile forces have become even more inhumane to China's hinterland, so much so that a certain invasion has unexpectedly flown to the hinterland of North China, which is only more than 100 kilometers away from the capital.

If it weren't for the dense radar arrangement in the key air defense areas near the capital and the dense radar network formed by the spread detection, the planes of the hostile forces would definitely fly over the capital in one go.

Although the hostile plane's plane was eventually shot down by the Air Force's combat readiness duty unit, the shock to the military and the top brass was far from over.

The planning to build an electron tube factory was one of the subsequent effects of this incident of enemy aircraft intrusion, because during the reconnaissance of the enemy plane, the ranging radar of a certain radar station was blinded by the interference released by the enemy plane, and after it was forcibly activated, the electron tube components inside the radar burst due to the rapid energization, resulting in the paralysis of the entire radar.

At that time, the technical maintenance team to which the radar on duty belonged did not have the spare parts of the damaged electron tube, and in the end they could only watch the enemy plane fly away overhead.

Therefore, the first task of building an electronic tube factory is to solve the problem of supplying spare parts for the radar unit of the Air Force.

However, listening to Bai Yi's words, it seems that the radars of Western countries led by Britain and the United States have begun to widely use transistors made of germanium materials.

Transistors, that is transistors, even if Lu Donglai does not think that more mature electron tubes will perform worse than transistors, but the semiconductors represented by transistors are the future development direction after all, which even the Soviets who have a soft spot for electron tubes will not deny.

As long as it is possible, Lu Donglai really doesn't mind putting effort into transistors, but the question is that China now has the conditions to accomplish this feat comparable to the world?

So Lu Donglai will be shocked, but compared to it, it is more of a deep powerlessness!

If Britain and the United States really popularize transistors on a large scale militarily, it will be tantamount to throwing off China for an entire generation, which will be very unfavorable to the military struggle along the southeast coast, which has a relatively high level of technology.

"What does it mean to spare such a big circle? Something to say! ”

Just when everyone didn't know how to face this serious problem, the head of armaments suddenly spoke.

"Of course, while developing electron tubes, we will not give up the research of transistors!" Bai Yi said.

"Transistors are naturally to be studied, but the problem is that we don't have the conditions at hand, just take the germanium single crystal you just mentioned, we can't even find the basic germanium element now, so how can we talk about transistors?" Lu Donglai came over at this time, and his tone was no longer perfunctory before, but with a sense of seeking advice.

"Is germanium not good?"

Bai Yi seemed to be a little surprised, but what was even more surprised than him was Lu Donglai, if the germanium element was good, the Soviet Union would still need to hold on to the electron tube and not let go.

It is not that the reserves of germanium ore in nature are really limited, whether it is mining or extracting is quite cumbersome, even with the Soviet Union's vast land and resources, the superpower with strong technology, the annual germanium production is also quite limited, otherwise where would the Soviet Union drill the tip of the horns of the electron tube, it has long been running along the road of transistors.

However, such a rare metal that is difficult to obtain, but where is Bai Yi like a rotten cabbage in a vegetable field? It can't be that there is something wrong with your ears, you heard it wrong!

Lu Donglai subconsciously wanted to save his body, but Bai Yi's next sentence made Lu Donglai become stunned: "That's impossible, there are so many coals in our country, and a considerable amount of germanium can be extracted by allocating a point, and then purified, and the germanium single crystal will be in hand." ”

In fact, Bai Yi wants to say that high-grade germanium ore is distributed a lot in Caiyun Province in the southwest, but where the bandits have not been eliminated, there are many hidden dangers; Second, there is no way to explain it if it is so rashly pointed out, so it is not mentioned in this regard.

But the method of proposing germanium from coal is not the slightest pressure on Bai Yi, not to mention that although the procedure for extracting germanium from coal is more complicated than that extracted from germanium ore, it is also the simplest and most practical of all methods, after all, the germanium element in the early years was separated from coal, so the method of extracting from coal, Bai Yi didn't think about it and said it as a matter of course.

It's just that Bai Yi didn't think about it, his rightful thing fell on the ears of Lu Donglai and others, and it was no less than a burst of earth-shaking thunder.

If this can be realized, it means that China can get a large amount of germanium in a relatively short period of time, and you must know that China's most scarce mineral deposit is coal.

"Xiaobai, do you have any good ideas? Tell me about it! Lu Donglai was really excited now, and the eagerness he looked at Bai Yi was no different from the eyes of a good guy looking at a beautiful girl.

But Bai Yi was taken aback, and he had the urge to put it aside immediately.

Where will Lu Dong let Bai Yi go, at this time, he can't wait to directly tie Bai Yi from Baiyun Factory to his Fourth Bureau of the Ministry of Industry, if such a talent is let go, he will definitely be angry.

Therefore, Lu Donglai's eagerness to attack was even more fierce, and he couldn't wait to pack himself up and send him over, which attracted the eyes of everyone around him.

In the end, even the head of armaments couldn't stand it, so he directly instructed Bai Yi to draft a detailed report on the method of extracting germanium from coal, so as to stop this matter.

However, when the group left, Lu Donglai still came to Bai Yi's side, hoping to go with him directly, Bai Yi also obeyed this, and he really vowed not to give up until he reached his goal.

If it was in the past, Bai Yi wouldn't mind being a favor, but now that there are many important things waiting for him, he might just pat his ass and leave.

So he could only refuse, which made Lu Donglai very unwilling, and he was reluctant to leave when he left, like a little daughter-in-law who couldn't bear to leave, so that Bai Yi had as many spicy eyes as he wanted.

It wasn't until all the people were sent away that Bai Yi pulled the car door weakly, but before he could do it, an old face with even more spicy eyes stretched out from the co-pilot, and then smiled flatteringly: "Bai Gong, don't forget about the barrel of the machine gun!" ”
