12月2日，我国中东部出现了范围比较大的大雾天气，中央气象台12月3日继续发布大雾蓝色预警，华北中南部、黄淮、江淮等地局部地区有能见度不足200米的大雾。雾天给公路、民航出行带来了较大影响，也给人们的生活、身体健康带来了影响。

On December 2,,East-central China appeared range is big fog weather,The central meteorological observatory on December 3, continue to release the fog blue warning,Southern north China/yellow/Jianghuai, local have visibility of less than 200 meters of the fog.Fog to highway/Civil aviation has brought great influence on travel,Also to people's life/Physical health of the influence.

　　冬季养生贵在空气新鲜，“日出而作，日落而息”，要早睡晚起，避寒保暖。保证充足睡眠时间尤为重要，从传统养生学的角度讲，冬季适当地增加睡眠时间有利于人体阳气的潜藏和阴精的积蓄，使人体达到“阴平阳秘，精神乃治”的健康状态。

Winter health is the fresh air,"Sunrise and,whether",Going to bed early late,Hibernate warm.Assure enough sleep time is particularly important,From the standpoint of traditional health preserving,Winter properly increase the sleep time is beneficial to human body sun be the spirit of hidden and Yin fine savings,Enables the human body to achieve"Yin pingyang secret,Spirit is to"Health state.

　　研究表明，冬季清晨空气污染最为严重，各种有毒有害气体因夜间温度下降而沉降于地表，只有待太阳出来，地表温度升高后，才能升高向空中散去。

Research shows that,Winter morning air pollution is the most serious,All kinds of poisonous and harmful gas for night temperature drop and sedimentation in the surface,Only to be the sun,After the surface temperature,To increase the air dispersed.

　　特别是冬季的清晨常常有雾，雾天不仅给交通造成不便，也能损害人体的健康，自古就有“秋冬毒雾杀人刀”之说。据测定，雾滴中各种酸、碱、盐、胺、酚、尘埃、病原微生物等有害物质的比例，比雨滴高出几十倍。如果冬季清晨在雾天锻炼，随着运动量的增加，人的呼吸势必加深、加快，会更多地吸入雾气中的有害物质，从而诱发或加重支气管炎、呼吸道感染、咽喉炎、眼结膜炎等诸多病症。

Especially in winter morning often foggy,Fog is not only to traffic inconvenience,Can also damage the health of human body,The ancient"Qiu dong poison fog kill knife"say.According to the measurement,Droplets of acid/base/salt/amine/phenol/dust/Pathogenic microorganisms, such as the proportion of harmful substances,Higher than the rain is dozens of times.If winter morning exercise in the fog,With the increase of the amount of exercise,People breathing will inevitably deepen/To speed up the,Will more suction fog the harmful material,So as to cause or aggravate bronchitis/Respiratory tract infection/Sore throat/Eye conjunctivitis, and many other diseases.

　　很多喜欢晨练的中老年人，在冬天天不亮，迎着雾气就出去锻炼，其实这不是锻炼身体，这是在瞎折腾，是在“糟蹋”自己的身体，经常如此，必生大病。

Many old people like to do morning exercises,In the winter days without light,To meet the mist went out exercise,In fact, this is not exercise,This is the blind flounder,Is in"spoil"His body,Often so,Will have a serious illness.

　　冬季天气寒冷，室内的温度要适宜，室温以18℃—25℃最合适，室内温度过高或过低都对健康不利。室内温度过高，会造成室内外温差过大，易引发感冒；室内温度过低，人体长期生活在低温环境中易引发呼吸系统疾病和心脑血管疾病。被褥的厚薄应根据室温的变化适当调整，以人体感觉温暖而不出汗为度。外出所穿的棉衣应以纯棉布为宜，要松软轻便、贴身保暖。

It's cold in winter,Indoor temperature to appropriate,Room temperature to 25 ℃ ℃ - and the most appropriate,Indoor temperature is too high or too low adverse to health.Indoor temperature is too high,Will cause too much difference in temperature of inside and outside,Easy to cause a cold;Indoor temperature is too low,Human lives for a long time in low temperature environment is easy to cause respiratory system disease and cerebrovascular disease.The thickness of the sheets should be according to the change of room temperature appropriate adjustments,To the human body feel warm and don't sweat for degrees.Wear out of pure cotton cloth cotton-padded clothes should be advisable,To soft light/Personal warmth.

　　冬季人体还要特别注意的保暖部位是颈部、背部和脚。

Winter will pay special attention to the human body's thermal part is the neck/Back and legs.

　　一要注意颈部保暖。有的人在冬季持续咳嗽且不易治愈，仔细观察一下，原来是因为穿开领服装暴露颈部，使寒冷的空气直接刺激气管所造成的，而改换高领服装并加用毛围脖后症状便消失了。

One should pay attention to the neck warm.Some people in the winter for cough and not easy to heal,Take a close look at,Because wear clothes get exposure to the neck,Make the cold air directly stimulate the trachea caused by,And change the turtle neck dress and add a fur collar symptoms will disappear.

　　二要注意背部保暖。背部是人体的阳中之阳，风寒等邪气极易通过背部侵入而引发外感性疾病、呼吸系统疾病和心脑血管疾病。注意背部保暖，宜穿棉背心，睡时也要保暖背部，避免寒邪侵袭，以免损伤阳气。

Second, we need to pay attention to the back to keep warm.The back is a human body of Yang in the male,Cold and evil easily through the back into the perceptual and causes disease/Respiratory system disease and cerebrovascular disease.Note back warm,Wear cotton vest,Sleep also want to warm back,Avoid cold evil invasion,To avoid the damage of sun be the spirit.

　　三是注意脚的保暖。足为人体之本，是三阴经之始，三阳经之终，与人体十二经脉、脏腑、气血相联系。常言道“寒从脚下起”，因脚远离心脏，供血不足，热量较少，保温力差，所以脚的保暖很重要。除了白天注意对脚的保暖外，每晚坚持用热水洗脚可促进全身血液循环，有增强机体防御能力和消除疲劳、改善睡眠的作用。

The third is pay attention to feet warm.Sufficient for the human body,Is the beginning of three Yin meridians,Three YangJingZhi end,And human twelve meridians/viscera/Associated with qi and blood.As the saying goes"Cold starting from the foot",Because of the feet away from the heart,vbi,Less heat,Insulation force difference,So feet warm is very important.In addition to pay attention to during the day of the feet warm,Every night with hot water to wash feet can promote the whole body blood circulation,Strengthen the body defense ability and eliminate fatigue/To improve the effect of sleep.

　　辐射雾 Radiation fog

　　辐射雾的概念

The concept of radiation fog

　　指由于地表辐射冷却作用使地面气层水汽凝结而形成的雾，并不是指这种雾具有辐射性。辐射雾在北方冬季、初春和秋末等季节比较常见。主要出现在晴朗、微风、近地面、水汽比较充沛的夜间或早晨。随着太阳的升高，地面温度上升，辐射雾也会立即蒸发消散。所以，早晨出现辐射雾，常预示着当天有个好天气。民间“早晨地罩雾，尽管晒谷物”、“十雾九晴”的说法就是指辐射雾。

Due to surface radiation cooling effect to ground gas water vapor condensation and the formation of the fog,Does not mean the fog is radioactive.Radiation fog in the northern winter/At the beginning of the season, such as John and more common.Mainly appeared in the clear/The breeze/ground/Water vapor is abundant in the morning or at night.As the sun rise,Ground temperature rise,Radiation fog will be immediately evaporation dissipation.so,Morning appear radiation fog,Often indicate the day have a good weather.folk"Morning fog to cover,Although sun grain"/"Ten nine fine mist"That means radiation fog.

　　辐射雾的特征

The characteristics of radiation fog

　　季节性和日变化：秋冬季居多；多在下半夜到清晨，日出前后最浓，白天辐射升温逐渐消散。

Seasonal and daily variation:In winter;Many in the small hours to early in the morning,Before sunrise the most concentrated,Daytime radiation temperature gradually lift.

　　与地理环境有关：潮湿的山谷、洼地、盆地。

And the geographical environment:Damp valley/depression/basin.

　　尺度：厚度几十米到几百米，平均150米左右，水平范围不大，分布不均，常零星分布，在平原上也可连成一片。

scale:Thickness dozens of meters to hundreds of meters,An average of 150 meters,Level range is not big,Uneven distribution,Often scattered distribution,In the plains also can connect a piece.

　　辐射雾的危害

The harm of radiation fog

　　辐射雾是在冬季最常见的一种雾，但对人体不具有辐射性伤害。但当大雾弥漫时，空气中的有毒、有害物质可能会与大气污染物发生一系列物理化学反应，从而产生新物质。如二氧化硫在大气中被氧化后，与雾滴结合成硫酸气溶胶，这一新物质的毒性要比原来的物质提高数倍以上。而且大雾时往往存在逆温层，空气无法对流，空气中的污染物很难扩散，所以对人体危害也很大。

Radiation fog in winter is one of the most common fog,But do not have to human body radiation damage.But when the fog diffuse,The poisonous air/Harmful substances may and atmospheric pollutants in a series of physical and chemical reaction,So as to generate new material.Such as so2 in the atmosphere after oxidation,Combined with droplets into sulfuric acid aerosol,This new material toxic than the original material increase more than several times.And when the fog often exist in the inversion layer,Air convection can't,The air pollutant is difficult to spread,So to human body harm is very big also.

　　辐射雾与平流雾的区别

Radiation fog and advection fog difference

　　辐射雾主要是因为夜间地面辐射冷却，使空气中的水汽达到饱和所致，因此雾多发生在夜最长、气温最低的冬季。只要满足条件，在大部分地区均可形成。

Radiation fog mainly because night radiant floor cooling,Water vapor in the air caused by saturated,Therefore fog occurs in the longest night/The lowest temperature in winter.As long as meet the requirements,In most areas are formed.

　　平流雾是暖湿空气移到较冷的陆地或水面时，因下部冷却而形成的雾。通常发生在冬季。一般出现在海边。

Advection fog is warm wet air moved to a cold land or water,Because of the lower cooling and the formation of the fog.Usually occurs in winter.Generally appear in the sea.
