- The sky was bright, and bursts of laughter resounded through the Xiaolai River. It was the migrant workers who went to Kunnan to work, passing the hospital pier by boat.
After more than half a year of continuous fighting, the people of Kunshan not only did not show signs of fatigue, but their morale became even higher. They sang continuously while going to work, and they were happy from the inside out.
With their energetic efforts, Kunnan¡¯s national epidemic prevention campaign has come to an end as soon as October has entered. A large number of civilians have transferred to the preparatory work for the third phase of the water conservancy project, and the winter battle in Kunshan County has quietly begun
News of the governor's serious injury was tightly sealed, so the people naturally had no way of knowing. They only knew that Jiangnan Hospital suddenly closed its clinics for a day yesterday, leaving many patients who had registered disappointed.
People are speculating about this. They don¡¯t know what happened, which actually forced the proud Jiangnan Hospital to close down.
It wasn¡¯t until they saw the several official ships on the pier carrying various flags such as governor¡¯s office, prefect¡¯s office, Shanghai County, etc., that they finally came to what they thought was a reliable conclusion ¨C it turned out that it was the officials who came to collectively see a doctor.
"Bah, these dog officials know how to harass us in Kunshan!" The common people pointed at the official ships angrily, dissatisfied that they were using their privileges to occupy Jiangnan Hospital.
But the scolding stopped abruptly when they saw the eye-catchingly beautiful Science No. 1 parked on the pier.
¡°It¡¯s so early, most likely Yanei is still sleeping on the boat, but it can¡¯t affect his growth
??~~
On the science number.
Qiaoqiao quietly pushed open the master bedroom door.
They saw Zhao Hao and Ma Xianglan sleeping soundly on the table with their heads leaning against each other.
There were piles of waste paper all over the floor, telling how hard the two had worked last night.
Qiaoqiao felt distressed and a little regretful when she saw it. Who could have prevented her from staying up all night and falling asleep in the first half of the night.
¡°Otherwise, you can be like Sister Ma and sleep with the young master justifiably.
Hey, our faces are touching each other!
Qiaoqiao then stretched out her hand, trying to push their heads away.
But he saw Ma Xianglan stretching and sitting upright.
"Ah, why did you fall asleep?"
Then, under Qiaoqiao's suspicious gaze, she straightened her slightly disheveled hair, stood up naturally, gently rubbed Zhao Hao's shoulders and said:
"Sir, go to bed and sleep."
Seeing her calm look, Qiaoqiao couldn't help but secretly blame herself, why should I think of Sister Ma as Hu Meizi? It's really wrong.
You should reflect carefully.
??~~
"It's a pity that Mr. Zhao didn't go to bed with him after all."
Qiao Qiao had just washed his face while he was coaxing him to have breakfast anyway, when Zhao Shizhen and Zhang Jian came.
"Master, what happened?" The two of them received a notice from Xiwa last night, saying that Zhao Hao had something urgent and wanted them to come back quickly.
They left Xishan Island at the fourth watch, hurriedly and slowly, and finally arrived at this moment.
As soon as he saw them, Zhao Hao stopped feeling sleepy and asked Qiaoqiao to serve the two disciples food. While eating, he chatted:
"Lin Zhongcheng encountered a fire and is still unconscious. Our science department should do something for him."
"But Master, we don't know how to treat diseases." Zhang Jian took a sip of the delicious shrimp porridge and whispered.
"The development of medicine has reached a bottleneck. If we want to make breakthroughs, we must rely on the development of science." Zhao Hao shook his head decisively: "Today we are going to try to do something epoch-making."
"What's going on?" The two disciples' eyes suddenly shone.
"Create oxygen." Zhao Hao said in a deep voice: "The current threat to Lin Zhongcheng's life is that tobacco poison enters the brain. How can this disease be scientifically explained?"
"Carbon monoxide poisoning." This is a knowledge point in "Natural Knowledge", and the two disciples of the Great Touch naturally opened their mouths.
¡°After carbon monoxide combines with hemoglobin, the hemoglobin loses its oxygen transport function, causing hypoxia in the body and damaging human brain tissue.¡±
"So oxygen therapy should be given at this time." Teacher Zhao said.
"Oxygen delivery?" Zhang Jian asked in confusion: "Isn't there oxygen everywhere in the air?"
They have done tests to measure air composition in the Beijing Science Exhibition Hall and know that air is composed of a variety of gases. They even know that oxygen accounts for about one-fifth of the total air.
"For treating patients, the oxygen content in the air is still too low." Teacher Zhao declared boldly: "So we have to extract pure oxygen!"
"Where to extract it from?" the two disciples asked in unison.
"Here." Zhao Hao said, picked up the crystal cup on the table and poured outHere comes some fresh water.
"Water molecules are composed of two hydrogen atoms and one oxygen atom. Oxygen and hydrogen can be obtained through electrolysis!" Teacher Zhao revealed the answer.
"Electrolysis?" The two disciples asked again: "Is it decomposition using electricity?"
"Natural Knowledge", of course, also introduces the most basic electrical knowledge.
??Such as lightning, static electricity, and the relationship between electricity and magnetism are covered.
"Not bad." Mr. Zhao nodded.
"Is it using metal coils to rotate in a magnetic field to generate electricity?" Zhao Shizhen asked immediately.
"Uh, yes" Mr. Zhao's mouth twitched and a few drops of milk leaked out.
"Then, master, how do you distinguish between hydrogen and oxygen?" Zhang Jian asked.
"Oxygen is released from the positive electrode, and hydrogen is released from the negative electrode." Mr. Zhao replied.
"That's easy." Zhang Jian and Zhao Shizhen looked at each other and smiled, and the latter said: "Insert two bamboo tubes into the water, buckle one on the positive electrode, one on the negative electrode, and then connect the pig urine bubble to the bamboo tube. Take care of the other end.¡±
"Since there are twice as many hydrogen atoms in water as there are oxygen atoms, the fastest gas to collect is hydrogen, and the slowest gas is oxygen." The former then asked seriously: "Right, Master?"
"It can be said that" Mr. Zhao smacked his lips and accepted the troubles of a group of genius disciples. Who would understand it?
??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? is a quick answer and can draw inferences from one example to other cases, making the teacher always feel like his intelligence is being ruthlessly crushed.
¡°Hey, I¡¯m so helpless
Mr. Zhao could only try his best to maintain his dignity as a teacher and said: "The volume of hydrogen produced by electrolysis is twice that of oxygen."
"Then can't we make hydrogen balloons?" The two disciples were completely excited: "We can also synthesize ammonia and prepare hydrochloric acid!"
"Stop, stop, stop." Teacher Zhao was stunned and said, "Where did you learn this from?"
"Didn't the teacher give us the textbook "Elementary Chemistry"?"
"Yes, the teacher would definitely not waste time explaining such a simple thing, so we taught ourselves." replied the two inventors.
¡°I have also done several experiments¡±
"I'm calling you crazy! I'm calling you crazy!" Mr. Zhao took the opportunity to vent his anger Oh no, he was teaching the ignorant disciples a lesson.
"Teacher, I want you to see if you're okay and let you do experiments?" He hit the two of them on the head with chopsticks like he was beating a drum, and cursed: "Do you know how dangerous chemistry is? Do you know? If you know it can¡¯t be done, you will lose your life!¡±
"We were wrong, Master" The two disciples quickly admitted their mistake.
Mr. Zhao then put down his chopsticks.
He feels so comfortable.
