On account of above reasons, the national product of Penicillium expansum alkaline lipase were chosen to study its interaction with chiral phenoxy acid herbicides, 2,4-dp, mCPP and2,4-dpm. 基于上述原因,本文选择国产的青霉扩展菌碱性脂肪酶为对象,研究了手性苯氧丙酸类除草剂2,4-dp、mcpp和2,4-dpm与脂肪酶的对映选择性相互作用。
With chlorinated polypropylene ( MCPP) and poly ( ethylene glycol) ( PEG) as raw materials, a kind of new comb-shaped amphipathic polymer containing PEG side chains attached to a MCPP backbone was synthesized in the presence of sodium. 以用等规聚丙烯改性氯化制得的氯化聚丙烯(MCPP)与聚乙二醇(PEG)为原料,在金属钠作用下,合成了以MCPP为主链、PEG为支链的梳形结构的两亲性高聚物。
The paper mainly analyses the registration errors caused by compressing distraction of paper during Multi-Color Press Printing ( MCPP). 本文分析了多色印刷过程中纸张压缩变形造成的套准误差。
The effect of 2,4-DP, MCPP on lipase catalytic kinetics and the chiral hydrolysis of 2,4-DPM by lipase were studied detailedly. 主要详细研究了2,4-DP和MCPP对脂肪酶催化动力学影响的对映体差异,脂肪酶对2,4-DPM的手性水解及其影响因素。
