When I left the police station, I saw Hei Yi washing his car in the parking lot of the police station, so I greeted: "Hey." Pen, fun, pavilion www. biquge。 info”

Hei Yi glanced at me, let the faucet in his hand continue to flow, I saw that he didn't seem to be able to keep up his spirit at all, I said, "Why is there no energy?" ”

Hei Yi curled his mouth and said, "The director asked me to wash all the cars." ”

I looked at my car, the blue and white color and the flaming red police lights all looked new, and I knew that it had been washed by Hei Yi, and I said, "Thank you." ”

Hei Yi said aggrievedly: "Actually, I didn't sleep last night, in order to watch the stay, they didn't handcuff him, I had to accompany him all night and watch him sleep, but who knows that he woke up early in the morning and said that he wanted to go to the toilet, I can't let him, right?" ”

Hei Yi's eyes are a little dark, of course, the sleepless night has an obvious impact on him, I am a little moved in my heart, but things always look at the consequences, I didn't grasp the kick at the door, and the whole effort was in vain, I said: "You should follow him." ”

Hei Yi said: "Yes, I also know this, but I was a little sleepy early in the morning, sleepiness will make people become casual, I thought that this kid looked quite honest, he didn't even turn over one night, and went with him, but my carelessness was used by him." ”

I don't know how to comfort this reckless young man, I just know that I have to do things at a glance, especially the work of the police, you can't be sloppy, and if you make a mistake, it will make a big mistake, what should I do? Car washing is the lightest punishment, I said, "You can rest assured first, the director didn't deal with you, it's already good." ”

Hei Yi said: "Who said no, do you still think he only asked me to wash the car?" He has stopped all my work, and I definitely can't participate in the Xuehai case. ”

I think of the joke that day, Hei Yi was still serious, Liu Da promised him to be transferred to the criminal police team, and now that something has gone wrong, Hei Yi must feel that his future is hopeless.

The feeling of Hei Yi jumping is still lingering in my mind, but bravery alone can't solve all problems, the reality is always so cruel, whether to go to the criminal police team is actually not the most critical, the important thing is to do the current work one by one, I said: "Hei Yi, there will be a period in the future, calm down, think about it, don't just be a brave man." ”

Hei Yi nodded, as if he understood what I expected of him, he said goodbye, and continued to turn on the high-pressure faucet, and the white and flawless water sprayed out, washing away the mud on the small pickup truck, revealing a blue and white striped police pattern.

I returned to Yejiawu, it was noon, the cafeteria had stopped at this time, I ate instant noodles in the office, and went to the laboratory building, first went to pick up the few eyelashes that were originally stored there, and then walked to the electron microscope room on the first floor.

In order to obtain a stable environment, the electron microscope is placed on the first floor, our electron microscope room is currently the most advanced electron microscope in the world, it is a field emission scanning electron microscope, which can provide nano-level high-resolution images, the function is not generally powerful, suitable for the morphology and organization observation of various materials, material fracture analysis and failure analysis, real-time micro-component analysis of materials, element quantitative, qualitative composition analysis, rapid multi-element surface scanning and line scanning distribution measurement, phase identification of crystal grains, grain size and shape analysis, Crystal, grain orientation measurement.

I usually use it less, I don't have to study it very carefully, I use it occasionally today, I don't know if I can make results, I turned on the electron microscope, but I found that I don't know how to start operating this advanced instrument, what should I do? There was a burst of smoke in my heart, and I looked at the eyelashes in the transparent plastic bag, thinking that things still can't be sloppy, or let Brother Murong teach me, right?

I called Brother Murong, and Brother Murong seemed to be taking a lunch break, and he said in a daze, "Su San, what's wrong?" ”

I originally thought that I would either forget it, and wake up Brother Murong from his sleep at noon, I really shouldn't, I said, "Either I'll talk about it later, it's okay now." ”

Brother Murong seemed to have turned his mind, and he said in a clear voice: "It's okay, Su San, what's the matter?" ”

I had no choice but to say, "Brother Murong, I am in the electron microscope room now, and the electron microscope will not be used." ”

Brother Murong smiled: "Little thing, I'll come over right away." ”

A few minutes later, Brother Murong appeared in the electron microscope room, Brother Murong is a master of electron microscopy, when I used to learn from him, he was already a master, now I think about it is really ashamed, people say that the monk of Shaolin Temple is a fist every day, and Qu does not leave his mouth, and now I only pay attention to the scene and the corpse every day, these powerful tools are not well used, even the electron microscope has forgotten how to operate, the fist is practiced every day, but Qu'er did not hum, now in front of Brother Murong is embarrassed, it is really embarrassing.

Brother Murong had already skillfully taken the material, made a sample, and placed it on the sample table of the electron microscope, so I could only look at Brother Murong stupidly from the side, and after a while, a high-definition image appeared on the host display connected to the side.

Brother Murong looked at the image, frowned, and said, "This sample is Chunhua's eyelashes, right?" ”

I nodded and said, "Yes, this is Chunhua's eyelashes." ”

As you can see from the picture on the monitor, some crystals are attached to the surface of the eyelashes, which is an image magnified by a million times, Brother Murong said: "Look, this is something that cannot be solved by ordinary magnifying glasses and the naked eye, even light microscopes can't solve it, but here in the electron microscope, it is pediatric, these crystals are obviously the residues of Chunhua's eyelash dye, you see, although her eyelashes have been washed by the water of the canal in the water, but these small dots cannot escape the eyes of the electron microscope." ”

I said embarrassedly: "Yes, I used to be focused on the scene, and I didn't make good use of such a good tool, so I'm really ashamed of this electron microscope." ”

Brother Murong put the sample on the scene into the sample table, and at this time, a high-definition image immediately appeared on the monitor screen, Brother Murong frowned again, his frowning look was very good, he looked very cute, I saw that he didn't let go of the knotted eyebrows, so I turned my head to look at the screen.

Brother Murong said: "Strange, this is the eyelashes extracted from the crossbar of the pedestrian bridge, right?" ”

I didn't know what Brother Murong meant, so I replied honestly, "Yes, is this strange? ”

Brother Murong didn't turn his head, and pointed at the screen with his hand, and said, "Su San, look, there is no crystal on the surface of the eyelashes of this sample?" ”

I looked at the picture and understood what Brother Murong meant, it turned out that there were no crystals on the surface of this eyelash, I said: "That's weird, this eyelash is adhered to the horizontal bar, it is original, it has not been washed by the river, if it is from Chunhua, it should have more crystals, right?" ”

Brother Murong glanced at me, and I also glanced at him, and the two looked at each other at this time, not knowing how to analyze it.
