据有关机构的调查显示，现代人在室内生活的时间越来越长，调查结果显示，城市人群每天大约有80%的时间在室内，而冬季比夏季增加10%以上，能够达到90左右。特别是一些室内工作者、儿童、老人和体弱多病者，在室内逗留的时间更长。

According to the survey of the relevant agencies, modern people live longer and longer in the room. The results of the survey show that the urban population has about 80% hours a day in the room, and the winter is more than 10% in winter, and it can reach about 90. In particular, some indoor workers, children, the elderly and frail and sick people spend more time indoors.

       其实这一点我们很好看见的，在冬季室温温度较低，在北方室内有暖气，人们一般都会选择待在室内；在南方虽然没有暖气，但是在没有阳光的情况下室内还是比室外温暖多了。特别是今年，入冬以来南方一直以阴雨天气为主，那么人们待在室内时间更是久。另外一方面，有了外卖，吃饭都懒得出去，有可能室内时间是100%。

In the south, people usually choose to stay indoors; there is no heat in the south, but it is warmer than the outdoor in the absence of sunlight. Especially since the beginning of winter this year, the South has been dominated by wet weather, so people stay indoors time is long. On the other hand, with takeaway, eating is too lazy to go out. It is possible that the indoor time is 100%.

呼吸系统疾病增多

Increased respiratory disease

在我国老年人发病死亡率时间分布调查结果中显示，每年的12月至次年的2月份是我国老年人发病死亡高发时间段，要比全年的平均数高出4倍之多。某医学研究院院长分析到，这种情况与秋冬季的气候、环境有直接关系，通过实验证明细菌可以附着于细小尘粒在空气中漂浮，这种细小尘粒被接触者吸入即可传染疾病。秋冬季人体的免疫力相应比较低，细菌和病毒对人们健康的危害更大。

The results of the survey on the time distribution of morbidity and mortality of the elderly in China show that the year December to February of the next year is a period of high incidence of death of the elderly in China, which is more than 4 times higher than the average of the year. A medical research institute, the dean of the analysis, this situation is directly related to the climate and environment in autumn and winter, through experiments that bacteria can be attached to fine dust particles floating in the air, this tiny dust particles can be infected by exposure to infectious diseases. In autumn and winter, the immunity of human body is relatively low, and bacteria and viruses are more harmful to people's health.

       据了解入冬以来，在医院门诊的人数中，大约有40%是呼吸道疾病，这要说和空气污染没有关系，小编肯定是不相信。就中国去年年末的三个月，雾霾波及的范围之广，造成的影响之大都是罕见的，特别是个别地方的PM2.5突破1000，更是让人唏嘘。就室内来讲，室外的雾霾这么大，躲在室内就没事吗？从得呼吸道的疾病人数来看，应该不是没事的。

Since the winter, about 40% of the out-patient numbers in the hospital are respiratory diseases, which is not related to air pollution. In the last three months of last year in China, the scope of the fog and haze spread widely, and most of the effects were rare, especially in some local PM2.5 breakthroughs of 1000. Indoors, outdoor haze is so big, is it okay to hide indoors? Judging from the number of respiratory diseases, it should not be okay.

问题三

Question three

通风排污效果降低

Reducing the effect of ventilating and discharging

夏季通过空气对流开窗会适量的散发室内的空气污染，但是冬季节装修完工后，当室内温度低于20℃时，开窗通风去除装修污染的效果便开始大大减弱。当室内温度低于10℃时，所有的装修污染将积存在室内，不再向外释放。即使整日整月地敞开窗户通风，去除装修污染效果不显著。再加上冬季人们本来就很少开窗，要开的话也不太会太久，这就更加的造就了室内污染物的堆积。

In summer, the air pollution of indoor air will be distributed through the air convection window in the summer. But when the winter festival is finished, the effect of opening the window and ventilation to remove the decoration pollution will be greatly weakened when the indoor temperature is below 20. When the indoor temperature is below 10 C, all decoration pollution will accumulate inside the room, and no longer will be released. Even if all the entire month open the window ventilation, decoration pollution removal effect is not significant. Besides, in winter, people seldom open windows. If they are open, they will not be too long, which will make indoor pollutant accumulation even more.

问题四

Question four

污染物质浓度增加

Increased concentration of contaminants

秋冬季门窗密封比较严密，室内新风量大大降低，而室内装饰材料和家具中释放出的甲醛等有害气体、燃料燃烧后产生的化学物质、吸烟时产生致癌物质，都会在室内不断增加而无法稀释。

The sealing of doors and windows in autumn and winter is strict, the indoor air volume is greatly reduced, and the formaldehyde and other harmful gases released from the interior decoration materials and furniture, the chemicals produced by the burning of fuel and the carcinogenic substances produced when smoking, will be constantly increasing in the room and can not be diluted.

随着秋冬季气温的不断降低以及暖气的开放，室内温度相对较高，建筑装修材料和家具中的一些有毒有害气体释放增加，而室内通风时间不断减少，使得室内环境中的有毒有害气体难以尽快消散，容易造成污染气体在室内的滞留，而人们为了躲避寒冷在房间内的时间也逐渐增多，室内空气污染的危害也进入了“高危险期”，因此为了家人和自己的健康，冬季室内空气检测治理和相关的措施，就很有必要了。

With the decreasing of the temperature in autumn and winter and the opening of the heating air, the indoor temperature is relatively high, and some toxic and harmful gases in the building decoration materials and furniture are released, and the indoor ventilation time is decreasing, which makes the toxic and harmful gases in the indoor environment difficult to dissipate as soon as possible, easily causing the stagnation of the polluted gas in the room. Stay, and people in order to avoid the cold in the room time is gradually increasing, indoor air pollution harm also entered the "high risk period", so in order to family and their own health, in winter indoor air detection and related measures, it is very necessary.
