In this sense , ida plays dual effects , tridentate chelating to cu ( 2 ) and bridge between two cu ( 1 ) andcu ( 2 ) . 3 metal complexes were selected as the appropriate for the study of cleavage plasmid pbr322dna by gel electrophoresis technique . the results showed ni and mn complexes could cleave effect - ively dna in the presence of h2o2 at physiological ph and temperature , whereas individual zn complex could cleave effectively dna 通过电泳实验研究了一系列金属配合物与pbr322dna的作用，发现在tris - hcl缓冲溶液中，生理条件下，镍、锰配合物在共反应物h _ 2o _ 2存在下能够很好的断裂dna ，而zn配合物单独作用就能够使dna由ccc型转化为oc和linear型。
The inserting method and properties of the composite materials in consist of omt and poly ( styrene - butyl acrylate ) had been researched ; the ultra - fine organic rigid particles crosslinked polystyrene ( xps ) has been synthesized by emulsion polymerization , the effect of the synthesis process on the size of organic rigid particles was discussed . the cause of the increasing mechanical properties of pp composite materials , which were strengthened and toughened with organic rigid particles and elastomer , had been investigated . the results of studying viscosity and precipitate height of sio2 nano - particles suspension showed that the sio2 nano - particles are very good dispersed by dp270 or cat 639w dispersant 通过粘度法和沉降法测定结果的一致性，说明分散剂dp270和cat639w对sio _ 2纳米粒子有较好的分散性， dp270的最佳用量为0 . 2时悬浮液粘度从35 . 1mpa ? s降为23 . 3mpa ? s ， cat639w最佳用量为0 . 4时悬浮液的粘度从35 . 1mpa ? s降为23 . 1mpa ? s ；通过研究分散剂存在下纳米粒子的苯丙乳液聚合动力学，发现纳米粒子的存在对乳液聚合有一定的缓聚作用，并讨论了乳化体系、温度、引发剂、表面处理剂以及纳米粒子用量对聚合的影响。
The crystalline structure changes of pp induced by pan - milling were characterized by x - ray diffraction and raman spectroscopy . xrd analyses show that when pp was co - milled with uhmwpe , crystal transformation of pp occurred , its crystallinity and crystallite size decreased , whereas , only slight reduction of crystallinity and crystallite size were observed and no crystal transformation was found when pp was co - milled with wtr chips , and amorphization of pp was strongly enhanced by co - milling pp with iron 采用x -射线衍射研究了聚丙烯碾磨粉碎过程微观结构变化， uhmwpe存在下pp发生晶型转变、结晶度降低和晶粒尺寸减小；弹性材料wtr抑制pp塑性变形，碾磨导致分子堆积有序区域膨胀，晶面间距增大，结晶度下降；刚性材料金属铁与pp产生强烈摩擦，加快晶粒细化，晶格破裂导致非晶化。
Furthermore , the combinations of cts with exogenous ca2 + and the factors elevating [ ca2 + ] i could raise the activities of gdh and gs , whereas cts declined the activity levels of gdh and gs after calcium messenger system having been blocked by calcium chelator ( egta ) , plasma membrane calcium channel inhibitors ( verapamil and lacl3 ) and cam repel reagent ( chloropromaize ) Cam拮抗剂氛丙漆在阻断钙信使系统后，也降低了gdh和gs的活性。同时， cts可以与外源ca ’ ‘及有利于胞质内ca ’ ‘浓度上升的因子(如dtt和atp )互作促进gdh和gs活性;而在egta 、异博定、 laci ，和氛丙漆分别存在下，则引起gdh和gs活性的减弱。
