monomer concentration meaning in Chinese
单体浓度
Examples
- Influence of different polymeric conditions , such as initiator concentration - > monomer concentration , temperature , t ime > solvent , on polymerization of monomers were investigated in detail
详细研究了聚合条件(引发剂含量、单体浓度、聚合温度、聚合时间、溶剂)对聚合反应的影响。 - Atr - ir , xps and colorimetric method were used to characterize the grafting density of the hydrophilic polymers on the plla membranes , which increased with the monomer concentration and the grafting time
采用atr - ir 、 xps和比色法表征了plla膜表面亲水性聚合物的接枝量，结果表明接枝量随单体浓度的提高和接枝时间的延长而增大。 - In the system the effects of photoinitiator and monomer concentration on grafting are not distinct , while photo - reduction time , uv irradiated polymerization time and uv light intensity have more effects on grafting yield
实验发现，光敏剂浓度对接枝率有一定影响；光还原时间增加，接枝率明显增加；聚合前期接枝率提高较快，反应后期增加缓慢；紫外光照射强度的改变会影响接枝率。 - High performance nanofiltration composite membrane with varied permeating flux and salt rejection was obtained by changing the monomer concentrations in both phases properly . in the case of composite membrane ( ii ) , the concentration of organic phase was enhanced to 0 . 5 %
改变两相单体浓度可以获得不同通量和脱盐性能的纳滤复合膜，如适当提高有机相浓度至0 . 5得复合膜( ) 。 - The content of styrene was found to be dependent on the investigated grafting conditions , of which the dose rate and monomer concentration were the major conditions , and the dependence of the initial rate of grafting on the dose rate and the monomer concentration was found to be of 0 . 4286 and 1 . 1662 orders , respectively . the results indicate that the grafting reaction is competitive and the copolymerization and the graft - copolymerization are existing at the same time . the grafting proceeds by the so - called front mechanism in which the grafting starts at the surface of the films and moves toward the middle of the film by successive diffusion of the styrene through the grafted layers
我们对辐射接枝反应中的各个因素如：单体浓度、辐射剂量率、辐射剂量以及反应时间进行了研究分析，结果表明：单体浓度和剂量率是反应的两个主要影响因素，它们对反应速率的影响指数分别为1 . 1662和0 . 4269 ；反应的动力学方程为： rg k [ d ] ~ ( 0 . 4269 ) [ m ] ~ ( 1 . 1662 ) ；认为接枝反应是一竞争反应，单体的均聚反应和在聚合物上的接枝反应同时存在，单体浓度的高低决定着竞争反应的方向；辐射接枝反应是从聚合物表面开始的，随着溶剂的溶胀和单体的扩散最后在整个膜体中形成接枝产物。
