通过在聚碳酸酯中加入不同抗氧剂以提高其热稳定性，研究了抗氧剂的种类、用量、环境条件对PC热稳定性能和降解动力学的影响。

Results show that protons are liberated by dehydration or dehydroxylation after calcination at 500℃. These protons disrupt the silicon-oxygen-aluminium bridges where there are Al substitutions in the tetrahedral sheet of the montmorillonite. Some of silicon-oxygen and aluminum-oxygen tetrahedral invert to react with the pillaring agents and yield covalent bonds which firmly fix the pillars to the host clay. The Al-MMT are thermally and hydrothermally stable up to 700℃.

经过500℃高温焙烧后，交联剂经脱水或脱羟基释放出质子攻击蒙脱土四面体层中Si-O-Al四键，硅氧四面体和铝氧四面体发生翻转，与交联剂发生反应生成共价键，形成稳定的层柱黏土材料，在700℃高温下，Al-MMT材料不仅具有较好的热稳定性，而且具有较好的水热稳定性。

几种二元羧酸钙中癸二酸钙对PVC的热稳定效果最好，当其含量达到1％时，对PVC已具有较好的热稳定性效果。

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.
