mortal train conductor

Chapter 365

Liu Qun comforted the elderly couple, and when he walked forward to the front of the carriage, he discovered an extremely uncivilized scene.

I saw a middle-aged male passenger lying shirtless on the seat next to the three people and looking at his mobile phone.

Although it is said that the service is what the host does as the guest does.But it does not mean that the guests can do things in their own way at will, and do things that violate social order and good customs, while the host turns a blind eye and pretends not to see it. If this is the case, it is not called service, it is called inaction.

Passengers' behavior is disrespect to other passengers, and train staff's inaction is dereliction of duty.

Liu Qun stepped forward and said, "Master, due to the special circumstances today, the temperature in our compartment is indeed high. How about this? I'll adjust you to the corresponding seat in the adjacent compartment with air conditioning. What do you think?"

Seeing Liu Qun talking to him and wanting to leave this comfortable place, the passenger said unhappily: "The air conditioner is broken and you don't hurry to fix it. It will be a boss after a while. I don't want to change places." , right here."

Liu Qun thought: This passenger looks a little dissatisfied, but it is really indecent for him to lie here shirtless, and it is really ugly for the passengers who come and go. As a train staff, although management is difficult, it is necessary It should be managed.

Liu Qun went on to say: "Master, although it's a little hot inside the carriage, if you don't agree to change seats, I have to trouble you to put on your clothes. You see, our carriage is a public place. People come and go, and there are many lesbians passing by, seeing your image is really not good."

The middle-aged man said: "It's nothing wrong. It's hot inside the car. I take off some clothes when it's hot. Isn't that a natural thing? It's not against the law."

Liu Qun patiently said to him again: "Look, our air conditioner is also repairing it. If you think it's too hot, we'll find you a spacious seat in the next compartment, but you need to put on your clothes. It would be bad if a tourist took a sneak shot of your image and posted it to a well-known video site."

The middle-aged man said: "I just don't want to wear it. I'm used to being shirtless at home. It's very uncomfortable to wear clothes outside in this hot day. The key is that the air conditioner is broken now, and I can't wear it at this temperature."

Seeing that he didn't listen to dissuasion, Liu Qun changed another method.

Liu Qun said: "There is no air conditioner in summer. It is normal for us to feel hot, but according to the results of scientific research, when the weather is relatively hot, the body temperature of wearing a piece of clothing is 1~2 lower than that of not wearing clothes." Spend.

That is to say, you will feel cooler when you put on clothes.Of course, this situation exists when the outside temperature is higher than the body temperature. Now you can see that the temperature outside the car has reached 37 degrees.After a while, the temperature inside the compartment will be the same as the outside temperature. Under such circumstances, wearing a T-shirt or shirt is cooler than being shirtless.

The middle-aged man said: "That impossible thing, it must be shirtless to cool off, is it possible to wear clothes to cool off? I have grown up to know that there are no exceptions, adding clothes when it is cold, and taking off clothes when it is hot."

Liu Qun said: "There are indeed exceptions to this, because at this time, when the external temperature is higher than the body temperature, the skin not only cannot dissipate heat, but will absorb heat from the external environment, so shirtless will feel hotter.

The skin is actually our body's first line of defense against the outside world. It feels very sensitive. When the temperature rises, we will feel a stuffy feeling through the skin, because the human body can maintain a constant temperature of about 37 degrees, mainly relying on The thermoregulatory function of the skin.

The heat dissipation of the skin accounts for more than 90.00% of the total heat dissipation of the human body.It is mainly done in four ways: radiation, convection, evaporation and conduction. We generally say that sweating is a way of evaporative heat dissipation. The amount of heat can reach about 4%, but the skin also dissipates heat through radiation and convection of air near the body.

But when the ambient temperature is higher than the skin temperature, evaporative heat dissipation becomes the only way for the skin to dissipate heat. If you are shirtless at this time, the skin will absorb heat from the outside world, and cannot achieve the purpose of heat dissipation through radiation and convection.

Seeing that Liu Qun spoke professionally, the middle-aged man also sat up and put his T-shirt on with some reluctance.

Seeing his beating and beating, Liu Qun was obviously very uncomfortable and unhappy.

He said to him again: "Master, how about we do an experiment today to see if the body temperature is higher with clothes or without clothes?"

The middle-aged man became interested after hearing what Liu Qun said, and asked, "Then how are you going to experiment?"

Liu Qun said: "Please wait a moment, I will go get the thermometer."

After speaking, he walked to the door of the power distribution room, and asked the inspector "Twenty-Five" for an infrared thermometer (used to detect the axle temperature of the train on the way).

After he walked over, he said to the middle-aged passenger: "Just use this instrument to measure your body surface temperature with and without clothes on, so that you can also have a comparison."

After speaking, he took the temperature of the neck of the middle-aged passenger who was wearing a T-shirt, and the temperature displayed at that time was 36.3 degrees.

Liu Qun said: "Look, this is the temperature when you are wearing a shirt. Let's try how high the temperature is when you are not wearing a shirt."

When the middle-aged passenger sat shirtless for two to three minutes, Liu Qun took the temperature of his neck again, which showed an impressive 3 degrees.

The middle-aged man looked at this comparison and said in surprise: "Oh, that's really the case. Although there is not much contrast, it is much cooler when it drops by a few tenths of a degree! Today's train ride is not in vain. I have learned a lot. one move!"

Liu Qun said: "My understanding is that after wearing clothes, the sweat will be released faster than without clothes, and it will be more uniform. Clothes will absorb sweat faster than direct evaporation and heat dissipation, and the external temperature is higher than Body temperature, if there are clothes to isolate, we will not be affected too much."

Seeing the middle-aged man's complexion turn from cloudy to sunny, and he put on his clothes very cooperatively, Liu Qun also reminded him: "We will repair the air conditioner as soon as possible. Before it is repaired, when will you think of it?" If you ride in other carriages, you can tell the conductor, and we will arrange you to a seat of the same level in the shortest possible time."

The middle-aged passenger said: "Okay, okay, I will sit here for a while to check the situation. If it is too hot, I will report it to the conductor. Thank you, conductor."

Seeing the cooperation of the middle-aged passenger, Liu Qun also expressed his gratitude to him.

The vehicle purser has already reported the breakdown to this section through the mobile phone.Professional maintenance technicians are coming by EMU with equipment, and it is estimated that they may get on the train for maintenance after four stops.
