Alkyl gallates can also low the extent of lipid peroxidation. To investigate the effects of PG and AG on livers that were injured by tetrachloride, we treamed small mice and fed them with different medicines, The conclusion is that AG and PG could scavenge free radical and protect mice livers from injuring by tetrachloride, AG was more effective than PG. 4. 3 The results of experiment for scavenging free radical of alkyl gallate in vitro showed that alkyl gallates can effectively scavenging free radical, but the parent gallic acid showed little effect. This suggested that introducing of hydrophobic group could significantly improve the anti-oxidative ability of gallic acid derivatives at large extent.

本文通过对城门山铜矿床主要成矿元素的因子分析，认为与花岗岩成矿作用有关的矿体具有cu－Ag关联结构模式，与石英斑岩成矿作用有关的矿体除有Cu－Ag关联结构，尚存在有Zn－Ag关联结构模式，成矿作用具有多期多阶段性。

By comparing the electrodeposition rate and the particlesize of nanometer Ag film prepared by methyl sulfonic acid silver system with those of nanometer Ag film prepared by nitrate silver system under the same conditions, it is found that the particlesize of nanometer Ag film electrodeposited with nitrate silver is smaller and the growth rate of the nitrate silver nanometer film is faster. During the experiment, the silver grain was smaller and the distribution was more uniform in the nitrate silver electrolyte than in the methylsulfic silver electrolyte.
