"You are the real big shots, and the fate of the country and the people will be handed over to you in the future, okay, let's not talk nonsense. Our first lecture is to talk about this planetary science, and look at the textbook in your hands, which is newly printed by us, and on the basis of the original author's work, new content has been added, you can open it and take a look. Today we will mainly talk about the evolution of this doctrine from the center of the earth to the heliocentr, which involves a lot of planetary orbits and some concepts at that time, to understand the general situation in our solar system, first of all, this is a two-dimensional solar system star map, we can clearly see that the planets are revolving with the sun as the center, look at these orbits, showing a near-circularity, and all belong to the same plane, don't worry, I'll show you a three-dimensional GIF in a while, through the movement of the planet, We can imagine that if we get from one planet to another, the distance is not a straight line, and we need to consider that the positions of the two are constantly changing, which is completely inconsistent with what we are on Earth. It's like two big trucks driving in different directions, you ride a motorcycle in the truck bed, you look for the shortest distance between the two objects while the two objects are moving, and then drive the motorcycle out of one truck and drive to the other truck, my analogy may not be very appropriate, but you can understand it, I am a person who is more interested in numbers and technology, and does not pay much attention to the art of speaking and the literary nature of the work. The old man was talking eloquently, and all the students in the spaceship piloting class were also listening attentively, obviously, in this case, there was no distraction and irritability, these seemed useless theories, but they might be used in every action in the future.

"I just finished reading this three-dimensional GIF,I'm going to introduce a digression,You are the spaceship piloting class,That is, the future pilot,The only difference between you and the civil aviation captain is that your responsibility is much greater than the captain,This is the spaceship in the science fiction movie,Very domineering look,This is just on the earth to look more technological,If it's really in the universe,You will feel its fading in front of the stars,Don't laugh! This is your means of transportation from now on! As a cadet of the Firefly Base and Space Army, I think you need to know something, Dr. Chen, an astronomy expert at our base, proposed the starship plan at the meeting two months ago, and it has become the second largest project in the country a month and a half ago, and now the spacecraft is still in the design, and now an ideal way is to expand and transform the existing aircraft carrier, and use conventional power to send a warship into space first, but this is not very beneficial to our country, which makes it very feasible for country M to send it up, However, our country's aircraft carrier is a scarce and precious resource, and we still have to keep it for national defense. If our country transforms the aircraft carrier, I believe that it will not be long before you will have to go to space, but unfortunately we do not have that condition. You don't have to be sad, our country's manned space technology is still one of the best in the world, we are fully capable of independently developing the first generation of spacecraft, even if our research is bad, it will be much stronger than using aircraft carriers to transform, for no other reason, but the design is different, for example, I prefer to use analogies, although my analogy is not in place. Let's use a helicopter as an example, no matter how good the helicopter is transformed, no matter how good its performance is, it is not as good as the most inferior fighter, because the two are not the same thing in themselves, the speed of the helicopter has reached its peak, and there will be no minimum speed of the fighter in the air, the principle is different. In the same way, our self-developed starship and aircraft carrier-converted spacecraft are not the same thing, so you don't have to feel inferior, you may enter space a while later than the space forces of other countries, but you will definitely feel extremely proud when you go to space. By the way, I want to remind you that all the information in the base cannot be disclosed to the outside world, you must understand your identity, the technicians of the base are always monitoring your mobile phone, once there is a leak, your mobile phone will be immediately invaded in the background, become a scrapped machine, and the messages you send will also be intercepted, if it is serious, the other party you send may also be blocked number, you have to be a little conscious. But you have all been selected through layers of selection, and I think you should be very clear about this, and I say this to remind you, lest you unknowingly make political mistakes, and the consequences are very serious, don't take it as a trivial matter. ”

A class ended quickly, which was completely different from the classes in high school and university, which were all impromptu according to future practice, and the theory was very practical, and after the old man left, a lecturer from the next base came after a few minutes. This can be judged from the hairstyle which subject he is a lecturer, this is a fifty or sixty-year-old man, authentic Mediterranean hairstyle, he walked up and plugged in his USB drive, showing his courseware on the multimedia, just opened it and seven big words appeared, "Welcome to advanced physics!" ”

"I don't welcome it at all." Chen Ruohan sighed and said, only to see her brows furrowed, and her expression was very ugly.

"What's the matter, our Miss Chen still has weaknesses?" Quan Tianyun said with a sense of ridicule, I didn't expect this little Nier to be afraid of physics, and thought she was invulnerable!

Chen Ruohan's face was ugly, and even a little pale, "No, I'm a little uncomfortable now." After Chen Ruohan finished speaking, he covered his little belly.

Quan Tianyun, who originally wanted to joke, suddenly realized that something was wrong, this Nizi really had some physical problems, "Are you okay?" Quan Qianyun asked with concern, in fact, this question seems a bit idiotic, and people look at it.

"I've got something, I don't know what's wrong." Chen Ruohan's expression was like he couldn't pull out his stomach, and his expression was very hideous.

Quan Tianyun lowered his head and saw that Chen Ruohan's seat was stained red, was she here to be a big aunt? Is it so ruthless? Squirted straight out? Quan Tianyun is a little sluggish, Bao Yuqian has never been like that, when I was in HN, when Quan Tianyun and Bao Yuqian were in the civil service community, Bao Yuqian also had a period, but it was not so exaggerated, is there really something wrong with her?

"Is this normal for you?" Quan Qianyun asked Chen Ruohan.

Chen Ruohan lowered her head and looked at it, even she herself was startled, her hand touched the bench, and the blood on the stain immediately began to drip down from her hand, "Quick, send me to the hospital." Chen Ruohan saw that he was like this, and his spirit became weak, and Du Xiaoyu on the side also found out that something was wrong, and he also looked here.

Quan Tianyun immediately stood up and shouted loudly, "Report, there are some situations here, and they urgently need to be sent to the hospital." Quan Tianyun fought, and immediately became the focus of the crowd, hundreds of people's eyes were focused on Quan Tianyun, Quan Tianyun couldn't take care of it so much, and after speaking, he picked up Chen Ruohan, the kind that the princess carried, because it was not convenient to carry.

"Please excuse me, excuse me, excuse me, let me go." Quan Tianyun carried Chen Ruohan and walked quickly through a few people from the middle seat and came to the aisle, because Chen Ruohan was facing upward, so others could not see Chen Ruohan's red buttocks, which also avoided embarrassment.

Quan Tingyun rushed out directly with Chen Ruohan in his arms, and when he passed by the podium, Quan Tingyun said sorry, disturbed, professor, and hurriedly ran out.

Along the way, Quan Tingyun was running, and Chen Ruohan was also bumped in Quan Tingyun's arms, which also attracted many comrades-in-arms on the road to stop and watch, this face was like love. Because Quan Tingyun had been in the hospital, Quan Tingyun rushed in with ease, and Chen Ruohan left a bright red mark along the way, connecting from the spaceship piloting ladder classroom to the hospital into an intermittent dotted line.

Looking at the man in front of him, Chen Ruohan's pain has disappeared a lot, and a sense of happiness is coming, if the chic man in front of him is his boyfriend, how good would it be, handsome face, extraordinary temperament and poetic literary attainments, full of humor between conversations, intentionally or unintentionally, with a golden height of more than one meter and seven, isn't this the standard of a scumbag? Why isn't he scum? It's not that no one chases him, but he likes him in the middle of nowhere, Chen Ruohan thought to himself.

"Doctor, come and save her, she's dying! Hurry up, hurry up! As soon as Quan Tianyun entered the hospital, he shouted, so that many people looked at Quan Tianyun and the girl in his arms, and immediately rushed out of the emergency room, three people wearing masks pushed the stretcher cart, Quan Tingyun put Chen Ruohan on the car gently, and the doctor quickly pushed the cart back.

"Hey, Chen Ruohan, don't die! When you wake up, you'll have to pay me a pair of leggings! Quan Tingyun shouted in the back, causing a snicker around him, directly Quan Tingyun's crotch was full of aunt red, and he didn't know that he thought that Quan Tingyun's aunt was coming, after Chen Ruohan entered, Quan Tingyun glanced at the people present, scratched his head awkwardly, and sat down on the blue seat outside the emergency room. Leaving Chen Ruohan behind at this time seems to be a little inhumane.

In less than two minutes, Du Xiaoyu also came over, "You shouldn't be so slow!" I'm still holding someone, and it's been two minutes since I've been in now, and you've just come here, something is wrong! Quan Tianyun was a little curious, Du Xiaoyu also looked strong, why was his speed slower than himself?

"You also said that if it weren't for you, I would have wiped the traces you left behind? Do you know that in the classroom, I used all my coat to deal with the blood on her seat, and I almost took off my pants, what an embarrassment, I wiped the blood you left all the way, can you not be slow! Du Xiaoyu said angrily, Du Xiaoyu took out his coat and gave Quan Tianyun a gesture, only to see that the inside and outside of the coat were all stained red, just like two children holding a brush dipped in red ink on each other's clothes.

Quan Tianyun touched his face helplessly, "Okay! I'm not right, when she's better, we'll ask her to pay us for our clothes, don't talk about you, look at me! Quan Tianyun pointed to his pants, Du Xiaoyu saw it, and immediately burst into laughter, and he didn't hold back in the hospital, and the nurse on the side hurriedly stepped forward to signal Du Xiaoyu to keep Du Xiaoyu quiet. Du Xiaoyu also gestured an OK with apologies,

"What's going on in the classroom now?" Quan asked.

Du Xiaoyu took out the cigarette case he was carrying, took one out of it, lit it and took a puff and said, "What else can I do?" If you go to class normally, it's not that the teacher is sick, can you still be unable to do it because a person doesn't go to class? Du Xiaoyu took another puff and found that this was a public place, so he immediately extinguished the cigarette butt on the ground.

"What you said makes sense, then tell me, what is the situation of Chen Ruohan?" Quan Qianyun asked again.

"Female hemorrhage, you just go to the Internet to search for it, see what the result is, and ask Du Niang for something!" Du Xiaoyu said it directly without thinking.

Quan Tianyun patted his head, yes! Why didn't I think of it! What do you want to do with the Internet? What do you want your brain to do!

Quan Tingyun opened Baidu and entered what caused the heavy bleeding in women, and the search results surprised Quan Tingyun, and it seemed that the several situations given were not very good.

Du Xiaoyu saw that Quan Tianyun's face had changed, so he asked, "There won't be anything, you read it to me." ”

"It's okay to miss it, but each one seems to be quite serious. When anemia occurs due to heavy menstrual bleeding in women, the main causes of heavy bleeding are as follows. First, female endocrine disorders lead to abnormal endometrial proliferation and cause heavy bleeding, according to the patient's bleeding situation, it is necessary to choose uterine curettage treatment or hormonal drugs for treatment, after the bleeding stops, you can choose estrogen and progesterone periodic therapy, or you can choose to place Mirena in the uterine cavity for treatment. Second, the patient has adenomyosis, endometrial polyps and other benign neoplastic diseases caused by heavy bleeding, need to curettage or drug hemostasis, after the hemostasis patients can choose drug amenorrhea or surgical treatment, endometrial polyps or submucosal fibroids and other conditions need to be surgically removed. Third, the hemorrhage caused by malignant tumor diseases such as endometrial cancer or cervical cancer is more dangerous, and it is necessary to embolize the arteries, and if necessary, surgical excision to stop the bleeding. Fourth, the massive bleeding caused by abnormal coagulation function in women needs to be treated with blood transfusion according to the situation, and the cause of the disease should be treated. When Quan Tianyun was reading, two nurses walked over, and Quan Tingyun didn't stop, as a man, you shouldn't feel embarrassed, especially a man who does big things.

"Then what do you think Chen Ruohan will be the first case?" Du Xiaoyu asked.

"The first one, the first one doesn't seem to be so serious, it's just an endocrine disorder, and it doesn't reach the level of carcinogenesis or tumors and other serious diseases." After saying that, Quan Tingyun's heart became a little heavier, although he had only known each other for a short time, Quan Tingyun didn't want such an unfortunate thing to happen to such a cute girl.

"I hope so!" Du Xiaoyu said, and after speaking, the two began to wait for a long time. During this period, people kept passing in front of Quan Tingyun and Du Xiaoyu, people came and went, but Quan Tingyun's heart was very quiet, and the quiet Quan Tingyun was a little uncomfortable.

An hour later, the doctor came out of the emergency room, and when the doctor came out, he took off his medical mask, "The bleeding has stopped, and the patient now belongs to the body's endocrine disorder that causes abnormal endometrium proliferation and causes massive bleeding." ”

As soon as the doctor finished speaking, Quan Tianyun and Du Xiaoyu showed joy, the doctor was surprised, I don't know why these two guys were so excited after hearing about the patient's condition, do they have a grudge?

"Great, it belongs to the first type, and that is to have a cure!" Quan said.

The doctor looked at Kwon like a sand sculpture, "What is the first kind?" The patient's condition is not very serious, she needs to be hospitalized for observation, you need someone to take care of her 24 hours a day, so that her bleeding does not recur, as long as these days have passed, that is, the observation period has passed, the patient does not need to worry at all. ”

As soon as he heard the recurrence, Quan Tianyun's joy dropped by half, and Chen Ruohan seemed to be bleeding a lot this time! Why don't you have to transfuse some blood, if you bleed it again, Quan Qianyun is a little distressed, it's all human tissue! It's such a waste, it's a shame. "Okay doctor, you treat her with all your might, and her whole family will thank you!" Quan Qianyun was a little incoherent.

"Rest assured, we are all comrades-in-arms and will do our best. By the way, what did you just say the first one? The doctor asked.

Du Xiaoyu said, "He just searched on the Internet for the cause of the girl's hemorrhage, and came out with several results, the first of which was that the condition was relatively mild." ”

"Oh, you said this first one! That's right, there will be several causes of hemorrhage, but don't worry, even if she takes all of these kinds and transports her to the underground hospital, the technology in the base can cure her 100%, not only these, but some other cutting-edge cancers, relying on the technology and equipment of the base, can also be cured. ”

"Underground hospitals?" Quan Tianyun was a little surprised, what the hell is the underground hospital? Is it underneath the base?

"Oh, you can know this, you should be the new Space Force, there is an advanced infirmary under our base, specializing in anti-cancer technology, and now it has achieved very fruitful results, now these technologies are not open and widespread, because it is too expensive, okay, you also know about it, you go to the nurse's station first and ask which ward the patient will be sent to, you go in first and wait, the patient will be sent to you in a while." The doctor felt that he had said a little too much, and there was not only an advanced infirmary under the base, but also other things, and it would be bad for these to be revealed, and there were still many people in the base who didn't know that there was still space under the base, and for these two newcomers, let them know about it, mainly to reassure them, and the doctor talked about the underground thing.
