查询词典 x-ray unit

A standard test method for evaluating the toxicity of chemicals to algae was applied; and 96h-EC50 of copper on inhibition of the growths of Chlorella pyrenoidosa, Scenedesmus obliquus, Closterium lunula were calculated as 67,51 and 202μg/L respectively using the method of probability unit for data treatment based on the test results. The results from the X^2 test of each dose-response equations showed that 96h-EC50s calculated were all precise and credible.

On the one hand,PH_x(x=2,1) can insert into the Si-Si backbond at elevated temperature,and a surface Si=P or a subsurface Si_3P unit was formed via subsequent H_2 liberations.On the other hand,the PH_2 species adsorbed on the Si_r site may completely dissociate across the other two unsaturated adatoms,and P adsorbed on the Si_r site may desorb in P_2 gas form at high temperature.

一方面，在高温下PH_x(x=2，1)可插入Si-Sibackbond，继而经过脱H_2步骤形成表面Si=P单元或次表面Si_3P单元；另一方面，吸附在Si_r位上的PH_2也可能在相邻的另两个Si adatom上实现后两个P-H键的解离，在高温下，吸附在Si_r位上的P可能以P_2的形式脱附。
