High dose copper induced decrease ofⅠ,Ⅱ,Ⅳ-2 content and increase ofⅢof spectrin. High dose copper can also decrease SA, PE content and increase SM, PS content.These showed that high dose can induce injury of erythrocyte by changing elementary structure and moity of membrane protein and membrane phospholipid, which may be one of the mechanisms of goat erythrocyte damage induced by high dose copper. 2. High copper caused the decrease of SOD and GSH-PX activity and the increase of MDA content.

In the seedlings time, the content of chlorophyll decreased by the deficiency of B, but the content of chlorophyll in the high efficiency cultivar decreased slowly than that of the low efficiency cultivar. This suggested that the leaves of the high efficiency cultivar can capture more light energy and the photosynthetic rate of the high efficiency cultivar decreased slowly. In the bolting time and blooming time, after two weeks of B deficiency treatment, the content of chlorophyll in the top leaves of the high efficiency cultivar decreased, and in the late time, the content of chlorophyll decreased slowly. But, the content of chlorophyll in the bellow leaves of the two cultivars had little changes. The reason may be that B in the high efficiency cultivar distributed to the propagative organ in the late growth, and the leaves were short of B.

For the first time we synthesized nanoscale metal hydrides of lanthanum, neodymium, samarium, dysprosium, and ytterbium with high efficiency under mild condition by complexometric catalysis instead of traditional preparation at high temperature and high pressure. It is for the first time that we synthesized lanthanide organic compounds with catalysts or initiating agents at atmosphere and ambient temperature,and some of them are new compounds. Nanometric lanthanide metal powders are prepared by thermal decomposition of the compounds in vacuum. Differently from the traditional method, size of the products prepared by our method is less than 40nm, and the activity of the reaction is very high. They are pyrophoric at atmosphere. They can make some reactions without activity or low activity show extremely high activity .We investigated influent regulations of methods, conditions to scale and special surface.
