2013年的科技界,热点不断。这其中,既有新发现,也有老问题。《科学世界》对很多事件都进行过报道和解读。让我们一起回顾一下这一年都发生了哪些科技大事。中国多个地区遭遇严重雾霾2013年新年伊始,我国许多地区就遭遇了大范围的严重雾曩天气。1月底.雾霾面积约140万平方公里,33个城市的空气质量达到了“严重污染”。10月下旬.东北地区发生大规模雾霾污染,机场被迫关闭,两千多所学校停课。12月上中旬,中东部地区又发生了入冬后最大范围的雾霾污染,多个地区空气质量达到六级,京津冀与长三角雾霾连成一片。
In 2013, science and technology circles are constantly hot. Among these, there are both new discoveries and old ones. Science World has reported and interpreted many events. Let's review together what major technological events took place this year. Severe haze in many parts of China At the beginning of the new year, many areas of our country suffered a large area of severe haze. At the end of January, the haze area is about 1.4 million square kilometers, and the air quality of 33 cities has reached “serious pollution”. In late October, massive smog pollution in the northeast region forced the airport to shut down and suspended more than 2,000 schools. In mid-December, the largest haze pollution occurred after the winter in the central and eastern regions, with air quality reaching six levels in many areas. The Beijing-Tianjin-Hebei region and the haze of the Yangtze River Delta are linked together.
