"In other words, senior, you carried that sister back for some reason, and the two of you spent the night together, and you were playing games all the time in the first half of the night, and you were catching up with Teacher Zhang's plan in the second half of the night, so nothing happened, right?" Xiaobai frowned, and summarized Xiang Yang's statement with great difficulty. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"Xiaobai knows me best! Will you trust my opponents? "The escalation of the incident in the morning was Lao Zhang's regular meeting, and everyone knew that Xiang Yang brought a girl back to the apartment last night. Even Lao Zhang, who has been serious all day long, inquired: "Xiangyang, do you have a girlfriend?" It's normal for young people to be affectionate and sweet, but pay attention to the impact! "The one who spread the news was either Xiaobai or Bobo, who patted his chest and promised not to say it, but he sold Xiangyang in a blink of an eye. What Xiangyang has to do at present is to block these two sources of transmission and start from Xiaobai!

"Senior, I believe in you, provided that you also believe in me! A girl who spent the night in your apartment in your clothes came out unstable and said it was the first time, but you told me that you didn't do anything! Although my nickname is Xiaobai, do you really think of me as Xiaobai? Or do you say," Xiao Bai rarely put away his smile and glared at Xiang Yang, "You don't want to be responsible at all!" You're still not a man, Xiangyang! Only then did Xiang Yang realize that his elaboration was more like evading responsibility, although the cause of this incident was a joke, but who could believe it?

"Trust me, Xiaobai!" Looking directly at Xiaobai, Xiang Yang landed and said loudly, "If you do it, you do it, if you don't do it, you don't do it, I Xiang Yang assures you with my personality that we really didn't do anything!" "I'll believe you for once!" The little white fox looked Xiang Yang up and down suspiciously, and asked, "A beautiful sister who has been with you all night, can you calmly play games and make plans, senior, are you sure you are a normal man?" "Nonsense!"

After this conversation, Xiang Yang has already made a judgment that it is not Xiaobai who spreads the news, but Bobo! Xiaobai can think about Lao Cai, which shows that he can be considerate and is a reliable person! Bobo, a 10,000-year-old game house, nests in the bedroom all day long, and has no common topic with everyone, it seems that Xiangyang's incident was used by him to brush up on his sense of existence!

Xiang Yang's fist clenched, and Xiao Bai asked coldly, "Senior, do you like that sister?" You should like her if you can carry her back from school for her and let her spend the night in your room in your clothes! That sister too, can accept all this you do, and make that kind of joke, she also likes you! Senior, why don't you let others say that she is your girlfriend? ”

Why explain? Why not admit it? Xiaobai and Junyi Feifei asked similar questions, and Xiang Yang couldn't answer. Even he didn't know that on the one hand, the girl he had a crush on was slim and slim, which made him very excited, and on the other hand, Cai Jieyu, who smoked, and her somewhat frivolous and bold actions made him extremely disgusted! This ambivalence has led to his current situation, liking, but trying his best to dissociate themselves from the relationship!

I found an excuse to escape from the classroom, and walked lonely in the empty corridor of the school's Guangzhi Building, thinking about whether to go back to the apartment or go to Bobo to settle accounts, when a voice came from the lecture hall next to me: "The surface of Jupiter is composed of liquid hydrogen and helium, and then deep into the center of the earth is liquid metallic hydrogen, and its core is a rocky core, about twice the size of the Earth and ten times the weight of ......."

The steps forward instantly froze, hydrogen? Liquid hydrogen? Metallic hydrogen in liquid form? I heard it right, hydrogen becomes solid at low temperatures, I can understand, what is called liquid metallic hydrogen? As a hydrogen elemental warrior, Xiang Yang is surprisingly sensitive to the word "hydrogen", and even through the door, he hears this faint voice.

After hesitating for a moment, Xiang Yang cautiously pushed open the door of the lecture hall and looked inside. "Slap", the narration stopped abruptly, and what Xiang Yang saw through the crack in the door was a middle-aged man with star-white hair and a professor-like appearance, who slapped the book in his hand on the podium and looked directly at Xiang Yang outside the door.

"Classmate, what time is it! It's almost lunch! Hurry to your seat! After the middle-aged man scolded, he ignored Xiang Yang and continued to preach, "Liquid metal hydrogen is composed of ionized protons and electrons, similar to the interior of the sun, but the temperature is much lower. At the temperature pressure inside Jupiter, hydrogen is liquid rather than gaseous, which makes it the electronic conductor and source of Jupiter's magnetic field, which is about 10 gauss, 10 times larger than Earth's. Also in this layer may also contain some helium and trace amounts of ...... I said, this classmate, you haven't come in yet, are you going to let me invite you in? ”

Xiang Yang was so unresponsive by the first scolding that he saw that the professor in front of him was angry, and wanted to say that he didn't choose this class, but he obediently walked to the back of the classroom. Staring at Xiang Yang and sitting in the back row, the middle-aged man reopened the textbook and said to himself, "Where did you come from just now?" ”

Sitting next to Xiang Yang was a boy in a sweatshirt, he saw Xiang Yang sitting down, and he didn't understand: "Brother, how good it is that you just said that you went to the wrong classroom, Professor Jiang has been named, you might as well not come at this time!" The electronic blackboard at the front of the classroom showed a cross-sectional view of a planet, and Xiang Yang asked familiarly, "Where are you today?" It's almost the end of the semester, and I'm going to get ready! The sweatshirt boy complained: "How long have you not been here, talk about Jupiter today!" The lesson of the earth was only taught last, and in the next building, Lao Jiang said that he would kill the gang of truants! ”

"Tell me about it, what is the situation of Jupiter, I may not understand it immediately if I suddenly intervene!" Xiang Yang sincerely asked, "I will definitely give you a copy of the summary of the notes for the final exam, help!" The boy in the sweatshirt was very moved, and said with a reluctant look: "Jupiter is a gas planet, mainly composed of hydrogen and helium, of which the hydrogen content is 84% ......"

As soon as the boy started speaking, Xiang Yang interrupted: "Gas planets? What about liquid hydrogen? "Don't interrupt!" The boy muttered dissatisfiedly and replied, "Gas planets have no physical surface, just like if you land on Jupiter and can only move like swimming." About 30,000 kilometers below the atmosphere is the liquid hydrogen layer, and further down is metallic hydrogen. ”

"What does metallic hydrogen mean in liquid form? Isn't metallic hydrogen solid hydrogen? "Who told you that metal is solid, you are not from the Faculty of Science, you don't have any common sense!" The boy said with a little disdain, "I'll give you a simple example, mercury is the only liquid metal at room temperature, iron melts into molten iron at high temperature, and it is still metal." Therefore, the key to metal-independent morphology is to reflect metallicity, such as thermal conductivity, electrical conductivity, electron loss and other properties. Rub, for the hair I feel like I'm in the pre-school popularization class? ”

"Then liquid hydrogen is metallic hydrogen?" "Leave me alone!" The boy in the sweatshirt raised his forehead and helplessly explained, "Liquid hydrogen is not metallic hydrogen!" Liquid and solid states can be reached at low temperatures, but to become metallic hydrogen, it must be at high pressure, ultra-high pressure, which is why I say that the liquid hydrogen layer is metallic hydrogen below! ”

Xiang Yang finally stopped asking, staring at the Jupiter chart on the blackboard in a daze, the boy in the sweatshirt couldn't help but breathe a sigh of relief, and suddenly heard Xiang Yang muttering to himself: "It seems to be ......" The boy looked back at Xiang Yang suddenly, and asked happily: "Have you found it too?" It's like ......"

The two said in unison: "The first sun!" ”
