Chapter 268

In the earphone, Charles, the leader, sounded from time to time.

"Computer line scan control, parameter setting, constant current setting 0.6na"

"Done."

"Johnny, set the needle tip bias to 60mV."

"The tunnel current is not stable enough, which may be due to the poor treatment effect of the needle tip."

Zhou Zhen said, "I just went to buy food before I handled it."

Johnny said, "OK, give me two minutes."

"Steve, the Z voltage on the piezoelectric ceramic material of the three-dimensional scanning controller is stable at 180mv."

"OK, OK."

Gardner, the team leader, carefully put the processed samples into the equipment. "I'm ready."

Charles's voice sounded: "Gardner, take the height change information, control the minimum delay time during probe scanning, and pay attention to controlling the angle direction and center of gravity offset. For the first group of tests, we adopt the constant current mode, and for the second group, we adopt the constant height mode."

"I see."

"Johnny, you are responsible for controlling the operation, slope correction and reciprocating scanning."

"OK."

"Phil, you control the motor, 3D imaging and data analysis."

"OK."

"Jamie, are you ready?"

"All right."

The scanning tunneling microscope looks like a science fiction world. The post-modern art full of beauty, together with other linkage devices, form a set of very dreamy equipment.

This set of equipment does not need manual control. Everything can be operated by the computer after setting the program.

The role that people can play is to change the program or adjust it according to their own needs.

Zhou Zhen mainly focuses on this, so that after returning to the earth, she can rely on her experience in this laboratory and link various equipment with this machine.

It's really fun to be able to control atoms, molecules, DNA, RNA and other genes and go further in the micro world.

At this time, Zhou Zhen also understood why those real scientists were not interested in anything else, including rights.

Zhou Zhen has already felt this kind of fun. He uses the equipment to separate a cell invisible to the naked eye into nuclei, cell membranes and organelles, with a special sense of achievement.

It is particularly interesting to study the invasion of those viruses to cells.

Although this kind of battle is the smallest battle, it looks like a single DNA or single RNA virus without home and nucleus. In order to survive, it instinctively invades cells in an attempt to turn other cells into its own home, which is no different from the war in the macro world.

But in this process, human beings seem to become God.

Zhou Zhen has this obvious feeling that he is manipulating other lives.

The start-up test is not one time, but uses various means to conduct different tests on the samples, catalyze and roughly evaluate the type of this enzyme according to the reaction degree of the enzyme.

This enzyme is classified according to the reaction properties, chemical properties and existing forms.

Only by understanding the various functions of this enzyme can it be better applied.

According to different methods of cross testing, Zhou Zhen and his colleagues need to conduct more than 20 primary response tests before they can determine an accurate direction.

Then, the enzyme should be decomposed, and the enzyme after stripping the protein and cofactors will lose its catalytic activity.

Enzymes are biological macromolecules with a molecular weight of at least 10000 and a large of up to one million.

At this time, we can understand the fundamental catalytic activity of the enzyme from the more microscopic molecular structure.

To do research, it is never enough to know its nature. We must know its reason.

Of course, such research will not end in a moment and a half. Each result can be calculated by computer before proceeding to the next item.

It was not until more than ten o'clock that Zhou Zhen and his colleagues finished the first phase of the test.

The samples were catalyzed again. After storage, the samples to be tested were placed in the sample tank.

At this time, they don't need the tightest protection. They can take off their protective clothing and monitor the computer.

Everyone was hungry, gulping at food and talking excitedly about the activity of this special enzyme.

Zhou Zhen is fine. She still has a lot of knowledge. Others are more excited about the emergence of this enzyme.

For them, finding an unknown enzyme may be more exciting than finding a girlfriend.

Everyone was talking excitedly and didn't want to go to bed at all.

But all three of them are graduate students, mainly with Charles. It doesn't matter if they don't go to class.

Zhou Zhen can't. at Harvard, the cost of absenteeism is too high.

"Jamie, I'm afraid the result won't come out until tomorrow afternoon. You can take Dana to a hotel to rest. You can come to know the result after class tomorrow."

"OK."

If this enzyme is regarded as a beauty, now they just take off the beauty's coat.

Thick shutters, they will continue to take off their clothes until tomorrow afternoon.

Therefore, Zhou Zhen is not in a hurry.

Maybe she was too tired after a long distance. Dana obviously narrowed for a while, and the oil on her face came out.

Seeing Zhou Zhen's promise, she picked up her bag and said, "please find a hotel nearby. It's good to be clean."

Zhou Zhen said with a smile, "we are the largest hospital area in the northeast, surrounded by all kinds of hotels."

"Don't pretend to understand, little virgin..."

Gardner just took a sip of coffee, looked at the computer, heard this sentence and burst out.

The key is that he dared not spray on the computer, barely bowed his head, splashed some on the keyboard, and sprayed most on his pants, and then coughed loudly.

Johnny laughed. "Dana, how do you know he's a virgin?"

"I'm the FBI." Dana was very proud and charming. She turned to Zhou Zhen and said, "let's go."

Zhou Zhen smiled and said to them, "I'm going to get rid of my virginity tonight."

Several people raised their fists. "Come on."

Dana gave everyone a white eye and said goodbye to Charles, who waved his hand impatiently without even raising his head.

Out of the laboratory, Zhou Zhen deliberately fell behind and observed Dana's figure.

When she was only in her twenties, she was much better than when she was in her forties and fifties.

In 1997, she also won one of the world's 50 most beautiful people.

Although her figure is not high, only one meter six, she is very hot.

When she went out, she couldn't help glancing back. "Have you seen enough?"

"No, of course not." Zhou Zhen is not at all embarrassed. "What's your budget?"

"Less than fifty dollars."

"There's a lot of room for choice. Isn't the FBI's salary very low?"

"It depends on what kind of work. I'm a specially hired technical work. How can we go?"

It was raining outside. Zhou Zhen looked and remembered that there was an umbrella in her car. "You wait..."

Ran to his car, Zhou Zhen found the umbrella, opened it, locked the car, and then returned to the gate. "Please..."

Dana took his umbrella arm and couldn't help pinching it. "I don't think you have such strong muscles."

"Without a girlfriend, I can only vent my energy on fitness and study."

She asked curiously, "are you really only interested in women older than you?"

"Maybe, at least you make me move."

"Ha, what a pleasure..." she was closer to Zhou Zhen's body. "Is the hotel near?"

"Sheraton is good. It's next to the Berkeley Conservatory of music. It takes 15 minutes to walk."

"Then we'll walk over."

"OK."

A woman willing to walk with you under an umbrella on a rainy night represents recognition.

Of course, it is also possible that she is giving herself more consideration, or investigation time.

As long as women take the bait, Zhou Zhen is never afraid of failure. His charm plus, coupled with his profound knowledge, is enough to fascinate most women.

And for this woman, she is tender grass!

Along the way, two people still quarrel, but their bodies are getting closer and closer.

Zhou Zhen didn't take the initiative until she passed a drugstore. Dana said, "I just don't want to regret myself, so don't think I'm in love with you."

"Is it because I'm still a student? You don't want to feel guilty?"

"I find you don't look like a bookworm who won't please women at all."

"This is because I met you."

"Wait, I'll go in and buy something. What size do you use?"

"I don't know. Maybe you need to measure it yourself."

She looked around, pressed Zhou Zhen tightly, and stuffed her hand into her belt along her strong lower abdomen. Then she pushed away Zhou Zhen and turned into the drugstore.

When they entered Sheraton, they were like a couple.

In the hotel bed, two people also do what lovers do.

At first, she said, "I don't believe you're a virgin."

Zhou Zhen explained, "I just learned from the video tape."

"Good at learning."

Later, she said hoarsely, "I believe you bastard is definitely a wolf who has never seen a woman..."

When Zhou Zhen was satisfied, she was already in a flurry of energy and was unable to move again.

But the next day, she was as energetic as taking tonic

So that the two fought again early in the morning.

"I have a cell class in the morning. It's very important. After class, I'll pick you up. I'll take you to eat lobster at noon. This is the best food in Boston."

She felt Zhou Zhen's chest muscles contentedly. "Get the results this afternoon. I can go back tomorrow."

"As long as you are here, I will accompany you."

After neither of them talked, although this kind of thing is not as common as eating and drinking water, they don't want to affect their lives after seeing each other and communicating.

As for the future, let's talk about it later.

Out of the hotel, Zhou Zhen was in a relaxed mood. She came to the world for several months and only relaxed once last night.

Recently, I feel depressed. After this vent, it's much better.

Now I think that the biochemical crisis world is mixed with other plots, so I'm not so worried. There's a feeling that he let the strong breeze cross the mountains and the boat goes straight to the bridge.
