Ban chlorofluorocarbons ! these compounds are destroying the ozonosphere and permitting more uvb to reach the earth ' s surface 禁止使用碳氟化合物.这种化合物正在破坏臭氧层而允许更多的uvb到达地球的表面。

Acid rain , greenhouse effect , ozonosphere broken and environmental pollution , etc , do harm to man constantly , and so gas - sensors " research and development is very active 酸雨、温室效应、臭氧层破环、环境污染等，不断危害着人类，从而，气体传感器的研究与开发十分的活跃。

Abstract : this paper deals with the earth environmental protection related to the destruction of the ozonosphere by freon from people ' s daily life , and human ' s active measures to meet this attack 文摘:综述了与百姓生活密切相关的氟里昂对臭氧层的破坏所带来的全球性的环境保护问题以及人类对这一问题的积极应战。

In the 21st century which is called “ environmental century ” , we are faced with various local or global environmental problems , as can be seen with “ ozonosphere being damaged ” , “ global warming ” , “ resource consuming ” etc 在有着“环境的世纪”之称的21世纪，人类正面临着不断出现的“臭氧层受到破坏” 、 “全球变暖” 、 “资源消耗”的许多地域或全球性的环境问题。

Research has shown that , even if destruction of the ozonosphere is stopped , it will still need about 100 years to renew it to a normal state . as a result , studies on the effects of ozonosphere thinning and the consequences of uv - b radiation on plant and ecosystem will not decline but on the contrary , is likely to increase in popularity 据有关资料反映，即使现在已停止对臭氧层的破坏并恢复到正常状态，估计还得100年的时间，所以有关臭氧层减薄紫外- b辐射增强对植物及生态系统的影响的研究，在相当长一段时间内不会减弱，还有可能加强。

This is so because climbing plants are likely to encounter intensive - changing environmental condition during their growth ( especially change of illumination ) . secondly , there is a large proportion ( 30 - 40 % ) of climbing plants which belong to dioecism , and hence a gap between male and female plants on morphology , biological characteristic , economic value and so on . this dissertation focuses on herbaceous climbing plants , perennial or annual species such as dioecious trchosahthes kirilowii maxin and dioscorea opposita thumb , and monoecious luffa cylindrical ( l ) roem , it attempts to discover how climbing plants adapted to various environments and the mechanism of adaptation from aspects of physiological and reproductive ecologies at present , due to overuse of chlorofluorocarbons ( cfcs ) , the ozonosphere has become thinner and thinner , and the ultraviolet - b ( uv - b ) radiation has increased considerably 而攀援植物本身是一类理想的植物行为生态学研究材料：第一，攀缘植物由于受攀缘能力和支柱木资源的限制，在生长过程中通常要遇到强烈变化的环境条件(特别是光照) ；第二，攀缘植物中具有较高比例的雌雄异株类型，通常占地区攀缘植物种类的30 40左右，不同性别的植物在形态学及生物学特性、经济价值等方面存在一定的差距，因此，本文以雌雄异株攀缘植物栝楼( trchosahtheskirilowiimaxim ) (葫芦科多年生草质藤本植物)和山药( dioscoreaoppositathunb ) (薯蓣科薯蓣属植物) 、雌雄同株异花攀缘植物丝瓜[ luffacylindrical ( l ) roem ] (葫芦科一年生攀缘草本植物)为材料，试图从生理生态学及生殖生态学角度揭示攀援植物如何适应不同生境及其机理。

The polyester fibre of resisting bacterium is one without which people can t live in modern times , but how to restrain the bacterium propagating excessively and keep people in health is a most important goal that fabrics and clothing industry are striving for . fibre of resisting bacterium can kill the bacterium effectively with the ratio of more than 99 % and it can restrain microbes . the polyester fibre of resisting ultraviolet radiation is also widely used . with the decreasing of ozonospheres in the atmosphere , there are more ultraviolet radiation in the sunlight which do harm to our skin , especially for those men working outdoors , it is more important to think about the way to lessen the harm . the polyester of burning - resisting has attracted more attention at home and abroad and burning - resisting textiles has been advanced definitely by law in many countries . our nation has also made strict claims in some special areas , such as fabrics in vehiciles and vessels , decorative fabrics in hotels . the everlasting burning - resisting fibres and textiles are badly needed . infrared ray fibre is also a new functional one that can absorb and reflect infrared ray after being processed physically . it s functions include physical therapy wet - ejecting and bacterium - restraining . this warm - preserving material can absorb the emitting heat from our bodies , at the same time it can also absorb and reflect the needed 4 - 14 urn wavelength ultraviolet radiation and accelerate netaboiism . fibre of resisting infrared ray is important in military areas 抗菌纤维具有永久的抗菌性，对金黄色葡萄球菌、大肠杆菌杀菌率大于99 ，能有效抑制细菌繁殖，起到抗菌防臭作用；抗紫外线聚酯纤维的用途也是异常广泛的，随着大气层中臭氧层的日渐稀薄，日光中的紫外线日益增加，对人体皮肤形成极大危害，尤其对于长期从事野外工作的人，因此设法减少紫外线对人体的伤害显得尤为重要；阻燃聚酯纤维则是一种倍受国内外人士密切关注的纤维，纺织品阻燃在许多国家已有明确法令规定，我国也逐渐在某些特殊使用范围做严格要求，如车船内用纺织品，高级宾馆的内装饰织物等，而且具持久性阻燃性的纤维和织物是现在更为需要的，真可谓用途非常广泛；远红外纤维也是一种经过物理改性后具有吸收并反射远红外线的新型功能性纤维，是一种具有优良理疗功能、热效应功能和排湿透气抑菌功能的新型纺织材料及保温材料，能吸收人体自身向外散发的热量，吸收并反射回人体最需要的4 14 m波长的远红外线，促进人体的新陈代谢；抗红外线纤维，则在军事上有着重要的作用。
