"Revolving door?" "How can this door turn?" A whispered discussion suddenly sounded around him, "Will this door lock us in when it turns?" "Why is this door turning?" What if we get stuck? ”

Sun does not hate the ghost, Sun hates Youyang to take my master

The tour guide stood there with an embarrassed face at the moment, she couldn't understand the words of this group of Meednos, and the Medeno people didn't have the slightest intention of going forward and entering the supermarket, just standing there like a group of hillbillies looking at the Western scenery. But at this moment, several children came from nowhere, laughing and rushing into the revolving door, causing several Medno people to gasp, and even Jacqueline almost screamed.

But the children were not at all dangerous, and they giggled and spun around the door as if it were a merry-go-round, and the children ran happily in it, and they had a great time, and they were very happy to see the Meedanors in fear.

"Come out! Can't play inside! A few men in pale blue uniforms scrambled out of the market and shouted at the children in the turnstiles, "Stay safe, come out slowly!" ”

The scolding of the security guards did not dampen the children's excitement in the slightest, and although they slowed down, they ran out of the gate again, rushed into the street like a flock of cheerful birds, and then disappeared around the corner. The security guards looked helplessly in the direction where the children had disappeared, and shook their heads with wry smiles. The revolving door this "magic equipment" since ancient times is to attract children's "entertainment equipment", whether it is the old world or this time and space, children like to run around in the revolving door, but the revolving door because of its design relationship, it is easy to get caught because of the rotation of the door, even adults may be injured when the speed is fast, and children are more likely to be seriously injured, so although the supermarket uses the revolving door such an eye-catching artifact, However, supermarket staff and security guards have been arranged to guard it to prevent anyone from being inadvertently injured.

Miro was the first to step forward, walked to the door that was still slowly rotating, hesitated for a moment, the tour guide saw that he was a little hesitant, and hurriedly said, "Don't worry, take a deep breath, go in at a normal pace, and it will be fine." ”

Miro was stunned, carefully watched the speed of the door rotation, took a deep breath, and then jumped forward a step into the revolving room the moment the door turned, the door turned slowly, Miro walked slowly forward with the speed of the door turning inside, and quickly jumped forward when the door turned to the exit, and finally jumped into the hall of the supermarket. Several security guards next to him looked at him with a relieved look, and couldn't help but cover his mouth quietly, obviously laughing, a woman in a red vest ran over and shouted at the security guards, "What are you laughing at?" You were worse than he was when you first came! ”

The security guards suddenly looked embarrassed, and some even blushed a lot, and quickly turned around and ran to their respective posts. The woman ran over and nodded slightly towards Miro, "Welcome to the Oriental Port Business Zone Supermarket, I hope you can find your favorite product." ”

"Well, thank you!" Miro nodded slightly to the woman in thanks, then began to look down the hall as she walked in.

The hall was very large, about fifty meters wide, and there was almost no end in sight ahead, and he even began to wonder if there was a boundary here. The ceiling of the hall was so high that there were no lights to be seen in the four corners, and even the gas lamps that were common in the port of the Orient were completely missing, and at this moment there were some regular iron frames hanging on the ceiling, and the iron frames were connected to each other, as if a hollow ceiling had been added to the ceiling. There are many vines entwined in the middle of the iron frame, and a lot of green leaves are dotted in between, as if these green plants have grown between the iron frames of the ceiling.

At every certain distance between the vines, there will be a strange oval glass ball, which is white and also emits light. The lights are so bright that they shine as brightly underneath them as if they were day. These glowing glass balls are obviously not flames inside, because the light obviously does not oscillate in response to the burning flames, and the brightness is very balanced, brighter than the usual gas lamps I have seen.

"What are these?" Miro asked curiously, pointing to the glowing glass balls in the air, and the woman in the red vest smiled slightly, "This is our electric light." ”

"Electricity? Lamp? Miro repeated it curiously, and the other party replied with a polite smile, "Yes, electric lights, our new equipment." ”

Sun Bu hated Ke Du, and Sun hated the main test star of the moon

These luminous glass bulbs are indeed electric lamps, but they are not incandescent lamps. The incandescent lamp is the earliest lighting lamp of human beings, but the shortcomings of the incandescent lamp are obvious, first of all, tungsten needs to be drawn into wire, this process is not impossible to do, but the failure rate of manufacturing is very high, not to mention that it is completely dependent on the tungsten filament in the incandescent lamp directly short circuit and emit light, electricity not only shines when it is working, but is used to generate heat, which can hardly be collected and completely wasted. In contrast, incandescent lamps not only have low light efficiency, power consumption, but also are not shock-resistant, and the red-hot tungsten filament will be directly broken under slight vibration and cannot be repaired, and the life span is extremely limited.

These are mercury lamps hanging on the ceiling, and they are not difficult to produce, as long as a certain amount of mercury is filled into a vacuum of rigid glass tubes, the mercury vapor will be discharged after the electricity is applied and emit a strong light. Because of its high light efficiency, long life, power saving and earthquake resistance, it has been accepted and promoted by the senate industrial system, it must be said that the shortcomings, mercury lamp is not without shortcomings, its voltage requirements are a bit high, mainly the voltage fluctuation can not be too large, if more than five percent, it is likely to cause the halfway out. However, if you turn it back on after the temperature has cooled down, you can restore the lighting, so this disadvantage is also acceptable.

With the use of these mercury lamps, the requirements of various departments for power supply have been put on the table, and many newly established factories have asked for power and water supply, which makes Pan Dai of the power department scratch his head. For the time being, it is difficult to achieve high-voltage power supply due to the serious lack of copper, and there is a lack of sufficient transformers to complete the conversion of high-voltage and low-voltage electricity, so in order to ensure the power supply of various departments, plants and daily life, it is necessary to set up a small power station near the power consumption point to ensure power supply.

At this moment, not far from the supermarket, two steam engines are snorting and steaming, the boiler is emitting the smoke of burning coal, the steam engine drives the axle crank arm so that a generator next to it is running rapidly, and two power department workers wearing hard hats are nervously looking at the power output pointer of the generator, adjusting the speed of the steam engine from time to time. With the self-production of generators and steam engines, the Heavy Industry Laboratory has shifted the task of producing steam engines and generators to the newly built Chapter 255 of "The Dawn of Passage" Chapter 255 Supermarket 2 has enabled anti-theft mode, and only half of the chapter is not connected to the content of the previous chapter.
