The single and joint mutagenicities of 1-NP and chlorophenols were studied.
研究了氯代酚与1-NP的单一和联合致突变效应,结果发现,各氯代酚对1-NP的致突变性有不同程度的抑制作用,且抑制效应系数(S)与各氯代酚的分子描述参数的关系能用QSAR方程表示,由方程得出的预测值与实验测定值之间能较好地吻合。
The Compton suppression factors (CSF) measured are about 2.
测得60Coγ射线源的康普顿抑制系数在能区100～300、300～800、800～1100keV范围内分别为2。
The horizontal sync supression coeficient and the vertical sync out in single stage,two stage and three stage vertical sync integrator circuits has analysed and compared with Laplace transform,therefore obstained result that two stage vertical sync integrator circuits is bast.
