Smog, as the name suggests, is fog and haze. Fog is a drop of water that floats in the air after the condensation of cold air in a specific climate, and moves and dissipates with changes in wind and temperature. The normal fog itself is white and appears when the air moisture content is high and the temperature is low.
Haze is a smoke mixed with a large number of gray smoke impurities, and the phenomenon of a sharp decrease in visibility is formed when the water vapor content in the air is not high, which is called haze, and most of the haze that has recently spread throughout the eastern and central parts of China is gray-white or gray-yellow. Sulfur dioxide, nitrogen oxides and inhalable particulate matter are the main components of smog, the first two are gaseous pollutants, and the last particulate matter is the main culprit of smog pollution. Among them, inhalable particulate matter is a general term for various particles with a diameter of less than or equal to 10 microns, and the generally familiar particulate matter is expressed as PM10 and, which refers to airborne particulate matter with a diameter of less than or equal to 10 microns and less than or equal to microns, respectively.
This fine particulate matter, itself is also an air pollutant, they are suspended in the air, in addition to blocking the line of sight and reducing visibility, but also play a role in adsorbing other pollutants in the air, such as aerosols with water mist, combined organic pollutants such as industrial emission compounds, soot and automobile exhaust, under the irradiation of sunlight to further chemical reactions, forming a carrier of more harmful pollution mixtures. Urban toxic particulate matter**: First of all, car exhaust imported from the United States Medical masks are good filtering, not only anti-particulate matter but also anti-droplets.
It can filter particles as small as microns and bacterial or viral vectors (commonly found in droplets) as small as microns. Using SecureFit patented technology, it adapts to different face shapes by adjusting to achieve a high fit for the health of you and your family, wear a mask when you go out.

In places with many trees, there is generally no haze.

There is a lot of fog on the mountain because the moist air rises along the slopes, and the temperature decreases with the altitude, causing the air to cool to a supersaturated state, and fog is produced in this state. Fog is a weather phenomenon consisting of tiny water droplets or ice crystals suspended in the air near the surface, and is the product of water vapor condensation (or condensation) in the air near the surface.
Fog: The temperature is relatively high during the day, and the air can hold more water vapor. But at night, the temperature drops, and the ability of the air to hold water vapor decreases.
As a result, some of the water vapor condenses into fog. Especially in autumn and winter, due to the long nights and the chance of cloudless wind, the ground heat dissipation is more rapid than in summer, so that the ground temperature drops sharply, so that the water vapor in the air near the ground is easy to reach saturation in the second half of the night to the morning and condense into small water droplets, forming fog. In autumn, winter and spring, the temperature is the lowest in the morning, and the fog is the thickest.

The clouds and mist on the mountain are because there are many trees in the mountain, and then there will be a lot of water, and the water evaporates upward, and the temperature on the upper side of the mountain will be relatively low (the temperature will drop by 6 degrees at an altitude of 1000 meters), and the steam will liquefy after being cooled to form very small water droplets, because it is very small, so it will not fall and form rain. However, if it adds up, it will rain because it can't bear it.

After the rain or in the drizzle, the top of the mountain will be covered with mist, dreamlike, infinite mystery, and fascinating. Standing at the foot of the mountain at this time, you can clearly see the white mist slowly spilling out of the mountain.
The mist in the mountains is like the heat of boiling water, and like the steam coming out of a hot pot, sometimes this vapor comes out slowly and thinly, and sometimes it comes out in a hurry. I don't know why I remember that there is a sentence in the "Thousand Character Text" that "clouds cause rain, and fog turns into frost", this fog rises from the water in the mountains, forms clouds and then rains, and the cycle repeats, forming a wonderful natural world.
This view is very beautiful from afar. Let people produce stuffy jujubes and give birth to infinite imagination. And this is especially common after rain.
The night is not clear, and the early autumn white dew group. Shake the jade on your shoulders and iron your hands to make Langyu. This is a poem written by the Tang Dynasty poet Bai Juyi, "Twenty Rhymes of Newly Planted Bamboo in the Summer of the Year Next to Secretary Lu".
What do the first two sentences mean? Interpret it, and the interpretation is also to learn from others, and add a little bit of your own understanding: it is late, but it is not yet night, and the air is already filled with a layer of green mist, and everything is hazy. In the mountains in early autumn, there are already small dew drops on the grass and trees.
Deliberately, the fog in the mountains has its own proper noun, called Lan, which refers to the fog in the mountains and forests. Such as Lan Qi (mountain fog); Arashiko (the brilliance of the mountain mist when it is illuminated by sunlight), and Arashimine (a misty mountain peak); Arashi fog (fog in the mountains); Arashi (clouds and mist in the mountains. Lan Qi is white.
In "Journey to the West", Dafan describes the mountains where the gods live, generally with beautiful scenery, strange flowers and plants, strange stones like treasures, and fairy mist.
There is an imagination called no reason, since I knew the poem "Blue Sky Day Warm Jade Smoke", I never thought of the original meaning of the poem (the original meaning of the poem expresses a love story), and when I saw the Lan Qi in the mountains, I always felt that the jade in the Qinling Mountains turned into gas and came out.
Looking at the mountains and rivers with a fairy spirit, although there is already a scientific materialist thought, I still wonder if there are immortals living at the bottom of the mountain? If you want to talk about clouds, everyone knows that this sentence "except Wushan is not a cloud", which is generally understood as (this paragraph is excerpted): People who have seen the Haohan Ocean, and then see the water elsewhere, they feel that it is so dwarfed and overshadowed, except for the gorgeous and colorful clouds of Wushan, other clouds really should not be called clouds.
I have never been to Wushan, nor have I seen the clouds of Wushan.
This year, it seems to have been raining all the time since the beginning of spring, and the mountains in the rain are a different landscape, and this phenomenon of clouds and mist slowly emerging from the mountains is particularly common. This ** is the Vermilion Bird spreading its wings, and the first highway can go to the Vermilion Bird Forest Park.
Looking at it from this angle, the mountain in front of me in the distance is very heavy.

If the heat of the ground is lost, the temperature drops, and the air is quite humid, then when it cools to a certain extent, a part of the water vapor in the air will condense and become many small water droplets, suspended in the air layer near the ground, and fog will be formed.
If the air contains more water vapor than the amount of saturated water vapor at a certain temperature, the excess water vapor will condense and when enough water molecules combine with the tiny dust particles in the air, and the water molecules themselves will bond to each other, becoming small water droplets or ice crystals. The amount of water vapor in the air exceeds the saturation amount and condenses into water droplets, which is mainly caused by the drop in air temperature.
Precautions for foggy weather.
1. Travel: Stay indoors.
It's best not to go out on foggy days, and it's better to stay indoors. Sun Yongchang, chief physician of the Department of Respiratory Medicine of Beijing Tongren Hospital, said. On foggy days, there is no wind and air circulation, and pollutants that are originally suspended in the air will take the opportunity to enter the human respiratory tract.
2. Skin care: clean more**.
Bai Yanping, chief physician of the Department of ** and the Department of Venereal Diseases of the China-Japan Hospital of the Ministry of Health, said that the pollutants in the air on foggy days have a greater impact on Qingxian. Therefore, be sure to do a good job of cleaning when you come back from outside. In particular, some people who are prone to allergies should do a good job of cleaning to prevent the invasion of diseases.
3. Joints: Wear an extra piece of "clothing".
On foggy days, the humidity is high and the temperature is low, so pay special attention to keeping the joints warm.
4. Exercise: Sweat slightly and then exercise.
When exercising on foggy days, warm up for a few more minutes, and wait until your body is slightly sweaty and your muscles are elastic before you start exercising. Li Jianmin said. Li Jianmin said that on foggy days, the humidity and cold are heavy, the speed of qi and blood in the meridians slows down, the nutrition supplied to the muscles is poor, and the muscles will be nervous if they do not get sufficient nutrition.
When the muscles regain their elasticity, they can protect the body from damage.

It rained for two days in a row, the weather was gloomy and gloomy, and there was no rhythm of sunshine. The birds were chirping at a loss, as if discussing when the rain would stop, and a few swallows with black spots flew high in the sky, and it seemed that the rain still did not stop them from catching insects. Like people who are very busy, it seems that they are not affected by the image of the weather, and still insist on working.
The room was a little dull, standing in front of the window, looking at the scenery in the distance, it seemed to see a fairyland. The fog in the mountains is empty and hail, and the mountains are looming, just like the fairyland of pure sails in the TV series, which is very beautiful, and the beauty is amazing. It's like having a pair of wings, and then flying into the mist to see if there are any gods.
Because the scenery is so fairy, like a painting.
After looking at the mountain, I looked at the trees downstairs, alas! It's really incomparable. Downstairs was originally an evergreen osmanthus tree, and you can smell the strong fragrance of osmanthus every October.
The floral scent is refreshing. Unfortunately, now the road has been re-planned and other unknown trees have been planted. Just planted, bare, not looking good at all.
I still like the old osmanthus tree. Usually green, when the osmanthus blooms, ten miles of fragrance. It's a pity that the smell may not be smelled in the future.
On the weekend, you can imagine the scene outside, there are almost no people, and it is deserted, because everyone stays at home on rainy days, and almost no one goes out to play. The advantage of having a house at home is that you can write and chase dramas with peace of mind. But there are also annoying things, and when I see my cub, I have the urge to beat her.
I just want to play, and I don't take my homework seriously at all. Headache! Forget it, in order to maintain a good mood, let's go with the flow!

Summary: She pushed open the door and entered, "I'm back, where is your notice, have you received it?" Mei'er avoided her mother's burning and anxious eyes, bit her lower lip and said, "Mother, I didn't get admitted!" Tears flowed down her face again......
Mei'er, Mei'er, what's wrong with you......Before the mother could finish her words, she felt a tightness in her chest and coughed violently. The eyebrows were lowered, the look in his eyes was dark, and there were unwiped tears on his long eyelashes. "Mother......Mei'er bit her lower lip slightly, revealing a row of white and neat teeth, "Don't worry about this, I know it myself."
The mother nodded, as if she had been released, and then gently admonished her eyebrows for a while, and then fell asleep again. Listening to her mother's snoring, Mei'er tiptoed down the kang, gently closed the door and went out.
The path is full of red, red, yellow and yellow wildflowers, and from time to time there are birds such as small sparrows or larks flying by the roadside, and their calls are so gentle and long. In previous years, Mei'er would definitely pick a handful of wild flowers in Chundan, pin them on his head and chest, find a secluded place, squat at the water's edge and take a picture of it, and then cover the red one with his hands. The smiling face turned his back and looked up at the lark in the sky, as if he was afraid that others would see it.
Now, however, Mei'er grabbed a handful of wildflowers and threw them into the air. Tears flowed into streams, and dark eyes looked desperately at the hollow valley in the mountains. "Mother-" Mei'er shouted. "Mother-" Mei'er shouted again.
Now Mei'er has made up her mind. She took out a big red post from her arms with a trembling hand, she opened it and looked at it carefully, and a few lines of eye-catching big characters on it came into view again: "You have been admitted to this college, please report to this school on the year, month, and day" Mei'er closed the post, and there were several eye-catching gilded words on it: "Notice of Beijing University".
She gently touched the cover of the notice again, and then jerked it into the valley, and the notice spun in the air several times before slowly drifting out of her sight. "Ahh My dream, my college dream, where will you go?
Mei'er muttered to herself. Then she raised her head and walked towards the familiar path. It's so foggy in the mountains!
The hut in front of her was closer, closer, and Mei'er knew that it was her hut, where there was her mother, who was sick and in desperate need.
She pushed open the door and entered, "I'm back, where is your notice, did you get it?" Mei'er avoided her mother's burning and anxious eyes, bit her lower lip and said, "Mother, I didn't get admitted!" Tears flowed down her face again......
The fog in the mountains is so big!
Causes of haze formation:
1. The physical base source for the generation of particulate dust. >>>More
Haze is caused by the excessive content of particulate matter (particulate matter) in the air, and most of the residues emitted through combustion in the process of daily power generation, industrial production, automobile exhaust emissions, etc., mostly contain fine particulate matter, which is a general term for solid particles or droplets with a diameter of less than or equal to microns in the air, which can enter the lungs with breathing, so it is also called particulate matter that can enter the lungs.
Causes: First, the physical base source for the generation of particulate dust. China has the world's largest loess plateau area, and its soil texture is the most prone to the formation of particulate dust particles. >>>More
No matter which brand of mask: first of all, you have to look at how many layers of protection, the material of each layer, among which activated carbon and meltblown cloth, are necessities, without these two materials, the filterability will be greatly reduced. Let's briefly introduce the HK mask, 5 layers of protection, each layer intercepts different harmful substances, and the filtration is as high as 99%. >>>More
1 The main components of haze.
The smog that obscures the view is mainly composed of sulphur dioxide, heavy metals, and inhalable particulate matter. The English abbreviation for particulate matter is PM; Generally, the particle size of the tube is less than or equal to 10 microns is called PM10, and the particle matter less than or equal to microns is called. >>>More
