今年是太阳黑子活动的高峰年,紫外线辐射也随之增加。紫外线(Uitravioletray)是太阳到达地面的光线中最强的能源,属于短波长的光,其中无法被臭氧层吸收的UVA及臭氧层吸收残留下的UVB到达地表。由于臭氧层被逐年破坏,到达地面的UVA量不断增加。UVB会引起皮肤红肿,产生黑班、雀班、日光角化症,导致皮肤癌;UVA会慢慢渗透到皮肤底层使皮肤失去弹性,产生皱纹、松弛等老化现象。紫外线如同一个隐形杀手,时刻危害着人们,炎炎夏日,要特别注意 This year is the peak of sunspot activity, ultraviolet radiation will also increase. Ultraviolet light (Uitravioletray) is the strongest energy of the sun’s rays reaching the ground. It belongs to short-wavelength light. UVA, which can not be absorbed by the ozone layer, and the ozone layer absorb the remaining UVB to reach the earth’s surface. As the ozone layer is destroyed year by year, the amount of UVA reaching the ground is constantly increasing. UVB will cause skin irritation, resulting in black classes, finches, sun keratosis, leading to skin cancer; UVA will slowly penetrate the underlying skin to lose elasticity of the skin, resulting in wrinkles, relaxation and other aging phenomenon. UV rays as an invisible killer, always endanger people, hot summer, pay special attention
