Under the influence of the sunlight and with the help of its strong oxidization capacity, the photo-catalyst can oxidize nearly all the organic matters on the surface into H 2 O and the corresponding nontoxic inorganic materials. At the same time, under the combined actions of the characteristic nanometer structure of its surface, the hydroscopic properties of the complex additives and the light-induced amphiphilic properties (hydrophilicity and lipophilicity) of Ti02 itself the surface of the glass is made superhydrophilic, so that it becomes easily washable, anti-fog and not vulnerable to recontamination to keep the glass clean and transparent. And it also has such functions as sanitization, sterilization, foreign odor elimination and air refreshing.

在阳光的作用下，光催化剂以其特有的强氧化能力，可将其表面的几乎所有有机物完全氧化为H 20及相应的无害无机物，同时在其表面特有的纳米结构、复合添加剂的吸水性和Ti02本身的光致两亲性的共同作用下使玻璃表面具有超亲水性，变得易清洗、防雾和不易被再污染而保持洁净透明，同时具有消毒、杀菌、消除异味、清新空气等功能。

No frosting and burnt rubber. Improves binding of rubber-rubber and rubber-steel or chemical fiber without contaminating mold. High temperature stable HS series improves high temperature safety in rubber masticating.

具有不&喷霜&、防焦烧增进胶一胶，胶－钢或化纤帘线的粘合，不污染模具，其中高温稳定HS系列物具有增强胶料练制中的高温安全性。

Recently, controversy on the use of chemicals in pest control is hot because some vector-born diseases reemerging, environment pollution going worse and resistance developing higher.

近年来，由于某些虫媒传染病发病率回升，加之所产生的环境污染及昆虫抗性等原因，对化学防制提出了一些不利的评价。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
