So Huang Shi clapped his hands, attracting the attention of these smiling children who were eating candy, "Children, wait until we go back to the classroom, I will show you a new treasure, but before that, I will talk to you about safety." ”

"Okay." This time, the children's answers were unusually neat.

"Did you all see this?" Huang Shi pointed to the two cordons set up on the periphery of the new foundation, one of which was yellow and white, and the white place was written in Chinese and English fonts, and some patterns prohibiting passage. The next one is also a cordon of the same color, but the difference is that the white areas are written with "attention", "safety", etc.

"I saw the ......" The children have long seen these two "cordons", but they don't know what the road is for, they look very light and soft, inserted in a few big iron rods, and flutter gently with the breeze, but because they recognize the words, they can vaguely guess the meaning.

"These two are called cordons, and its function is to ......" Huang Shi then introduced them to them, but because he was anxious to see Ling'er, he said the role hastily, in fact, the focus is to remind these children that they should pay attention to safety and do not play on the edge of the construction site.

"Chief, we know the truth." After hearing this, the children also understand, because the role of these is not like the official cards in the honor guard of those big officials, if someone collides with the official, the light will be reprimanded, and the heavy will be killed, so just take it as a quiet and evasive brand.

"Alright, kids, let's go back to the classroom." Huang Shi was afraid that Meiling would leave after packing up, so he urged the little ones to go back quickly.

So a group of children hugged Huangshi and walked in the direction of the classroom, but before Huangshi went to meet his sweetheart, he did not forget Wu Nanhai, who was still working hard, he called through the walkie-talkie, and asked Wu Nanhai to press the foundation by himself, and then went to eat by himself, no need to wait for him, as for the celebration will be postponed and opened.

Wu Nanhai, who received the notice, didn't know that Huangshi was forgetful, and he went to meet his lover privately, thinking that he had something more important. After receiving his call, he was very moved, the chief had something important to deal with, and he would say hello to him, so he secretly decided that although the chief was not at the scene, he must do things well.

……

"Ling'er, what are you laughing at?" Huang Shi took Meiling's slender left hand and asked puzzled.

Meiling covered her mouth with her right hand and smiled, because as soon as Huang Shi entered the door of the classroom, he winked at her, and then led the group of little guys to her, pretending to be cold and asking for warmth, looking serious and the person who was anxious two days ago, just like two people.

Then he coaxed away the little ones who were light bulbs under the pretext that it was almost time to eat, saying that he would introduce them to the new magic weapon when they had finished eating. After they were gone, I was afraid that they would not go far, so I quickly flashed to the door to check, and when I saw that there was no one left and right, I was relieved to come back and take her little hand.

Feeling that his sneaky image just now was somewhat obscene, Huang Shi hurriedly diverted Ling'er's attention, "Ling'er, I specially sent you this new gadget today. ”

"Well, chief, is that what it is?" Ling'er asked, looking at the magic weapon on the textbook table.

The artifact didn't look high, but it felt very heavy, and on the solid white pedestal, there was a small black platform, and then along the pedestal was the curved arm. On the white handle, two small cylindrical black pillars protruded, like the two horns of a cow.

Huang Shi nodded, this Olympus microscope is not inconspicuous, but it cost him 25,000 oceans, speaking of which this microscope is the cheapest, because he is in someone's sales store, the first model introduced is Olympus BX51WI-DPM, its price is actually 450,000, Huang Shi was stunned at that time.

What is so expensive, the clerk told him that it is because the observation head is a wide field of view, the number of fields of view is 22 focus, the condenser is Abbe condenser, the converter can be replaced with five holes inward, and it is a six-optical system, the stage is still a ceramic coating with high wear resistance, in short, it is worth the money.

Worth?! Huang Shi secretly complained in his heart, it seems that someone went to find a young lady with good skills, and as a result, someone introduced a night that costs tens of thousands of yards, which can't help but make people ask whether this is inlaid with gold or jade, and this is not a star, so he hurriedly said, "This is too expensive." ”

"Too expensive?!" The clerk secretly sneered in his heart, what a big sum, dressed like five people and six people, but as soon as he entered the door, he asked if there was the best microscope, and now he introduced him to the best microscope, but he thought it was expensive. However, although he was very disdainful, the clerk's face did not show any color, but on the contrary, he became more and more enthusiastic.

"Mr. Huang, this one is Olympus IX71-F22FL/DIC, and its price is 370,000."

"It's still too expensive!"

"Then this one, I'm sure you will like it, Mr. Huang."

"How much is that?" Although Huang Shi didn't know what kind of clerk he was doing to introduce him to such expensive equipment, it didn't seem to have anything to do with the hundreds and thousands of microscopes in the school he remembered, but he forgot that when he was in school, it was more than 20 years ago.

The current price level, coupled with the injection of various scientific and technological content, this microscope is naturally becoming more and more expensive, Huang Shi does not understand this, he is still listening to the clerk introduce various types of high-powered microscopes to him one by one.

"Olympus BX51-P, this one is 180,000, its main functions are......"

"What about this one, Olympus IX51, as long as 130,000, with it......"

In fact, the clerk introduced to Huangshi all bio-grade equipment, this kind of biological microscope is used to observe biological sections, biological cells, bacteria, living tissue culture, fluid precipitation, etc. Generally speaking, the biological microscope is a necessary inspection equipment for QS and HACCP certification in food factories and drinking water factories.

However, Huang Shi didn't know about these, he just felt that they were beyond his psychological price, he just wanted to show the children the cells and bacteria of flowers, birds, fish and insects, and now it costs hundreds of thousands of oceans, which is inevitably very distressing, and when he was about to find a reason to run away, he finally heard the clerk talk about a price that he could accept.

"Mr. Huang, then I will introduce another one, this is also the most cost-effective one in our store, if you are still not satisfied, then I can only introduce you to these portable products." With that, he pointed to the row of display cases behind him.

Huang Shi looked at the place he pointed, and there was a row of things that looked like digital cameras in the display case, and he couldn't figure out whether it was a microscope plus digital functions, or a digital camera plus microscopic functions, but in line with the principle of resolutely not buying things he didn't understand, he replied, "Okay, then you can talk about the price first." ”

For Yellowstone, these portable microscopes are actually sufficient, and they can achieve 450 to 600x magnification, which is comparable to Levine back then. Hooke's improved light microscope was much more advanced, because in 1683, Leeuwenhoek only added a lens to the microscope. Although only one lens was added, it was able to magnify the specimen up to 266 times, and in this way it was the first person to see many single cells.

These portable microscopes are mainly an extension of the digital microscope and video microscope series developed in recent years. Different from traditional optical magnification, handheld microscopes are digital magnification, which generally pursue portability, small and delicate, and easy to carry.

Moreover, some handheld microscopes have their own screens, which can be independently imaged from the computer host, which is easy to operate, and can also integrate some digital functions, such as supporting photographing, video, or image comparison, measurement and so on.

But Huang Shi didn't know what to do, so as soon as he heard the clerk's offer, "Mr. Huang, you only need 240,000 yuan, and you can move home." ”

"Okay, I'll buy it." So although he was very heartbroken, he immediately bought it.

……

Meiling let Huang Shi take her little hand and walked to the microscope, her heart full of sweetness. Because the classrooms are located some distance from the residential area, there are usually no people passing by except for the students.

And in the past two days, Hong'er has always used this or that excuse to stop coming to eat with her, Meiling Zhilu said that since that day, there has been a gap between her and Hong'er, and all this is because of the man who is holding her hand now.

Huang Shi didn't know this, he was now like a naughty child showing off his toys to an adult, "Ling'er, look, this is a microscope that can make one of our leg hairs thicker than our waist, or I'll pluck one of your leg hairs and try it." After saying that, he deliberately looked at Ling'er's skirt.

"Chief......" Meiling glanced at Huangshi with disgust, and ducked back with her skirt.

"Well, well, if you don't want to, just pluck my hair." Huang Shi smiled and shrugged, stretched out his arm, rolled up his sleeves, and showed his hair, all saying that horses have long thin hair and long lazy hair, but Huang Shi thinks he is a very diligent person, but he also has long and thin hair on his arm.

In Ling'er's laughter, Huang Shi bared his teeth several times, and finally endured the pain and pulled out a hair, "Ling'er, don't laugh, don't laugh, although Zhu Zi said that it is not good to pluck a hair and benefit the world, but I have to contribute a hair to scientific research today." ”

After speaking, he solemnly brought the hair to the corner of his mouth and blew it gently, "Come on, come on, change and change." "Then I put it in the middle of the stage.
