How many batteries are there on a general submarine (including nuclear submarines)? At least 200 batteries. That is, battery submarines alone will be able to stay underwater for half a year.

Don't underestimate the time of half a year, although a nuclear submarine can stay underwater for a longer time, the submariners can't stay there, and staying for a long time can make people crazy! Therefore, half a year is enough.

Of course, in order to ensure that there are no mistakes, the submarine must also have a set of backup battery packs with independent circuits, so that the number of battery blocks must be doubled, that is, 400 pieces.

These 400 batteries are a bit too much for nuclear submarines, but for those conventional submarines that are loaded with 5 or 600 batteries at any time, it is not a problem at all, and it can even save some submarine space.

"How about Uncle Bao, can you use a lead-acid battery with such an index?" Yang Tang chuckled.

"It works, it works!" Bao Youxin was quite excited, "It's a pity that it's not a smaller lithium (ion) battery......"

Yang Tang shook his finger when he heard this: "Uncle Bao, it seems that you still don't know enough about submarine batteries!"

Bao Youxin's face froze: "Why don't I know enough deeply?"

"The battery parameters I quoted are based on the size of the battery cell on the conventional submarine in the eighties and nineties, that is to say, and then control the interface standard, the battery can be used directly, and if it is a lithium battery, due to the small size, but the actual discharge capacity is two or three times that of the original lead-acid battery, so there must be more battery blocks, and then the battery (group) management will be a huge project, and the programming of automatic control will be a rather troublesome thing......"

In fact, when it comes to battery management, we have to mention the take-off and landing management on the aircraft carrier, due to the complexity of the entire system engineering and in order to better deal with some unpredictable emergencies, the take-off and landing management of the aircraft carrier has been carried out by a manual team, including the Mi Guoyan.

Relatively speaking, the battery management of the submarine is not as complicated as the take-off and landing management of the aircraft carrier, but it is also a system engineering that must be careful and rigorous, even if the new management software can be programmed within a year, but its test and error correction work may be as long as several years, just like an online game, constantly updated and buggy, until the online game is closed, and there is a bug that has not been fixed.

Therefore, whether to adopt the new battery control or directly follow the old management method, the efficiency and error rate are obvious!

"Battery management, I know, I've heard of it...... Looks like you're thinking it all through. Bao Youxin was slightly embarrassed and said, "By the way, what about the formula?"

Yang Tang spread his hands and said, "Why don't you give it to you now? Can you call the shots? Do you know how much my recipe is worth?"

Bao Youxin was stunned for a moment, and then waved his hand and said, "I'm sorry, I think it's wrong...... By the way, the old leader also asked me to ask you, when will the training of those three people take place?"

Yang Tang said: "The medicinal materials are in place, and they can be used at any time." ”

"Where are the herbs transported? You have to give me an address!"

Yang Tang thought for a while and said: "There is an unfinished building in the Fourth Ring Road (see 525 for details), which originally belonged to the Yin family, and now it completely belongs to me, basically the decoration is completed, and it is being put there for ventilation!

"Is there anyone guarding over there?" asked Bao Youxin.

Yang Tang groaned for a while, and was about to answer, when Yang's mother's voice came from downstairs: "Xiaohong, it's time to eat!"

"Eh~~ It's coming, it's coming......" Yang Tang hurriedly responded, and turned to Bao Youxin impatiently and said: "Let the boss watch it yourself, anyway, if there are one or two less medicinal materials, the training will not be busy." As the words fell, the others had already turned into the stairwell.

Bao Youxin didn't dare to get angry with Yang Tang, shook his head with a smile, took out his mobile phone and called Luo Lao, and gave a detailed introduction to the situation of chatting with Yang Tang.

Forbidden Garden, Luo Lao's office.

Putting down the phone, Luo Lao was blank for a while.

"What's the matter, Lao Luo, what surprised you?" said the old man who was tasting the genuine tea, "It can't be that Yang Boy really has other good things in his hands, right?"

"Yes, yes, but how to say it!Oh, don't talk about this yet!" Luo Lao scratched his head with both hands, "Let's talk about the training first, Yang Xiaozi said, the medicinal materials are transported to the seventh floor of an unfinished building in the Fourth Ring Road, as long as the medicinal materials are in place, the training will start immediately." ”

"Transported to an unfinished building in the Fourth Ring Road!......? Is there a mistake?"

"That's right, the unfinished building was originally Yin's, I heard who mentioned it once, and now, Yang Xiaozi has bought it, and it is said that the interior is almost decorated. Luo Lao Dao.

"That's pretty much it...... But so many medicinal materials, all transported at once?" Gao Lao asked a new question, "Those medicinal materials are not cheap, is there enough security force in the building?"

Luo Lao smiled bitterly: "Listen to the meaning of the bun, Yang Xiaozi wants us to look at that batch of medicine." ”

Elder Gao was a little speechless, but after pondering for a while, he said, "It's completely okay, it's enough to transfer a company of people from the reconnaissance battalion of one of the armies under the jurisdiction of the garrison!"

"It's not impossible, but the supply of a company is not a small amount!"

"Let Boy Yang ......"

"Do you think it's possible?"

"Then the supply of the reconnaissance company in normal times will be double-supplied, this will be fine, right?" After Gao Lao finished speaking, he picked up the confidential mobile phone on the coffee table and called the garrison to convey the order.

At the same time, Luo Lao wrote a string of data on the note, and when Gao Lao finished calling, he handed it over.

Elder Gao glanced at it: "What is this?"

"That's right, a lead-acid battery, judging by the volume data and interface data, once put into production, can directly replace the submarine battery. Luo Lao Dao.

"But your discharge in this hour, and the data of this fifty hours of discharge, is it marked with one more zero?" Gao Lao obviously knew something about his army's submarine battery, "Actually, it is one less zero, and this data is exaggerated enough...... Eh, wait, this, this shouldn't be another good thing in Yang boy's hand, right?"

"It's indeed a good thing in Yang Xiaozi's hands, but I have repeatedly confirmed the data, and it's not wrong!" Luo Lao said, "At present, the internal structure diagram and lead-acid formula related to the battery are in Yang Xiaozi's hands, once the practicality of this thing is confirmed, what should we do?"

Gao Lao said with a solemn face: "This thing is different from the formula of medicinal materials, if you confirm that you want to use it, you must buy the formula and hold it in your hand." ”

"I think so too, I'm afraid of ......"

"If you want money and things, as long as Yang Xiaozi puts forward conditions, we can discuss it. "Gao Lao cut the railway," but the formula must be mastered by the state, of course, the premise is to get the physical object of a single battery first, test it, and see that the data on the note is as different as the data. ”

"Okay, let's just follow this line of thought!" Luo Lao tilted his head and said, "It seems that we have both had to spend time on this matter recently, and the spring training work in the major (war) areas below ......"

"It doesn't have to be a unified arrangement, I think they can do it themselves. Elder Gao was obviously tired of the boring spring training year after year, "Otherwise, the commanders of the various districts will be left there as decorations?"

"Okay, just do as you say!"

Half an hour later, Bao Youxin, who had just finished the table after eating and drinking at Yang's house, received Luo Laoxin's instructions, so he had to continue to communicate with Yang Tang with a bitter face.

"Let me provide the actual battery?" Yang Tang was stunned, "Yes...... But you have to provide the raw materials and the processing equipment. As he said this, he asked the Red Queen to pass a list to the printer.

After the list was printed, Yang Tang tore it off and handed it directly to Bao Youxin: "Uncle Bao, the raw materials needed for the battery, as well as the processing equipment, are all here, you let the top watch it, presumably it should not be difficult to provide a few copies, just transport the things and medicinal materials to the same place." ”

"Okay, I'll pass the list to the old leader!" As he spoke, Bao Youxin took a picture of the list with his mobile phone and sent it back to the Forbidden Garden.

After a while, he received a short message: "The battery list is being prepared...... The medicinal materials are in place tonight, and there is a company of people who are in charge of taking care of them. ”

Bao Youxin immediately showed the short message to Yang Tang.

Yang Tang said: "In this case, tomorrow at half past ten in the morning, on the ninth floor of the Rainbow Building, the training will begin!"

"Rainbow Mansion?"

"It's the unfinished building where the medicinal herbs are put in. ”

Bao Youxin: "......"

The next day, Yang Tangkan, who had been exercising for the super training box in the morning, rushed to the classroom at eight o'clock, but before he could sit on his buttocks, Vice Principal Cai came to the door again.

Sure enough, it was for Donado's guess.

The school wants to award money to Yang Tang, and plans to hold an academic exchange conference such as a celebration party again.

Yang Tang said that if the prize money is to be paid to him, it will be paid if it is not paid, and he will definitely not attend the academic exchange conference.

Vice President Cai was suddenly helpless, in the face of Yang Tang, who had a tough attitude, it was impossible for him to come hard, even if the school of Beijing University did not dare to come hard, after all, like Yang Tang, a "mathematical strongman", if Beijing University did not stay, some universities would welcome it with both hands.

"Yang Tang, don't worry, the bonus promised by the school will be transferred to your account soon, but you should think about the academic conference, right?"

"No, don't think about it, I don't have time to ......" Yang Tang saw that Vice President Cai's face was a little ugly, and added, "Recently, I've been studying the Bonhard conjecture, but I really don't have time!"

"You, you said Bonhard conjecture?" Vice President Cai was almost stupid, and his speech became stammering.

You must know that although the Boernhard (Riemann) conjecture and the Donado (Poincaré) conjecture are both two of the "world's seven major mathematical problems", in terms of importance, the Bonnhard conjecture can be said to be the first, because there are thousands of inferences or generalizations based on the establishment of this conjecture, and the mathematical system established is huge.

"Yes, Bonhard conjecture. ”

"Then, then I wish you good luck!" After saying this, Vice President Cai left in a daze, and did not mention the matter of sitting at the academic conference.

After the first two sessions, Yang Tang was about to leave the classroom, but he didn't think that Concubine Tao Yu, who was sitting in the girls' pile before, took the initiative to sit next to him, lowered her voice, and said timidly: "Something is wrong......

"What?" Yang Tang was in a hurry to go back to the Green Field Garden to pick up Yang Dad and Yang Mom, and then he had to rush to the Rainbow Building, "Let's go to the car to talk about something, come with me!" As he spoke, he grabbed Tao Yufei's little hand and walked out of the classroom, but as soon as he arrived in the corridor, he was blocked by Fang Tangjing.

At this time, Fang Tangjing was no longer the only one by his side, Chang Kun was no longer alone, there were four or five other tall and tall guys, and at a glance the fierce look on his face, he knew that he was not the kind of good stubble.

"Hehe, I've met the little white face again!" Fang Tangjing looked at Yang Tang with a playful expression, as if he was about to play with the cat of the mouse.

Yang Tang turned a deaf ear to Fang Tang's ridicule, and turned his head to look at Concubine Tao Yu: "This is the little problem you said?"

Concubine Tao Yu hurriedly shook her head: "No...... I mean, my dad found out about you and me!"

Yang Tang laughed when he heard this: "Uncle knows about the two of us, it can't be better." Speaking of this, his voice suddenly turned sharp, "Begonia!" The words fell, and the students around him only heard a few muffled sounds of "dong dong dong", and Fang Tangjing and his dogs all fell to the ground with their stomachs in their arms, curling up and wailing and rolling. The key is that during the whole process, Yang Tang did not move at all, but no one found the murderer who attacked Fang Tangjing's gang.

"Let's go!"

Yang Tang took Concubine Tao Yu's hand and swept over Fang Tangjing and the others who were about to die on the ground. Concubine Tao Yu looked at their miserable appearance, and said a little worriedly: "They won't die, right?"

"Don't worry, you can't die, it will hurt for a while at most, so that they can ......remember it for a long time."

When she got downstairs and got into Yang Tang's car, Concubine Tao Yu asked, "Who did it just now?" Why didn't I see anyone?"

Yang Tang started the car and slid out of the parking space and replied: "It's Haitang, she has been following you and guarding you in the past few days." As he spoke, the car had turned onto the main road.

"Guarding me, why didn't I find out?" Concubine Tao Yu was surprised, but she didn't blame Yang Tang for secretly sending someone to protect her, but she didn't inform her in advance.

"Begonia's strength is not something you can imagine, in short, with her following you twenty-four hours a day, I am more relieved. Yang Tang said indifferently.

"But the problem right now is my dad's side...... It's all to blame on Tan Yuchen, he guessed that I had something to do with you, and then inadvertently said that he leaked his mouth. Concubine Tao Yu said angrily.

At this time, the car had already driven out of Beijing University, and Yang Tang subconsciously accelerated at the same time, when he heard Tao Yufei's words, he couldn't help frowning slightly: "Concubine Fei, do you think that Fang Tangjing blocked the two of us at the right time just now, is there anyone here to report the news?"

Concubine Tao Yu hesitated for a moment and said, "Maybe...... Yes!"

"Then you said it was a classmate or an uncle who reported the news?"

"Huh, do you doubt my father?" Concubine Tao Yu glared at Yang Tang a little angrily.

"Or maybe it's someone from my uncle's side?"

"Huh?" Concubine Tao Yu was a little furious at this moment, "You want to say that there are ghosts in our family?"

"I don't know, it's all just speculation...... Okay, don't think about it so much, you can sleep for a while, I have to hurry home!" he added, adding two more points of throttle.
