Pvp polyethylene pyrrole alkane ketone whether one physiology have similar human plasma high polymer of albumen , the best one in the ion surface - active agent of right and wrong Pvp （聚乙烯吡咯烷酮）是一种生理学上类似人体血浆蛋白的高分子聚合物，是非离子表面活性剂中最好的一种。
Abstract : a kind of additive for light newspaper was prepared from natural high polymer through a series of chemical reactions . and the technology was studied for the application 文摘:以天然高分子为基本原料经一系列化学反应制备一种适于轻量级新闻纸的添加剂，同时对应用进行了工艺研究
The great amount of stabilizing agent led to the non - uniform of the plating layer . the addition of the high polymer could decrease the size of silver particles and help to increase the dispersibility of powders 采用高铜镀液，镀覆表面金属颗粒降至2 3urn ，形成一层致密连续的铜银共沉积的金属膜层。
The following significantly inhibit drug diffusion : large particle size , higher polymer concentration and polymer molecular weight , and reducing the drug solubility in the aqueous phase by adjusting the ph 以下因素可显著抑制药物扩散：大粒径，较高的聚合物浓度和较大的聚合物分子量，及通过调节ph值减少药物在水相中的溶解度。
In this paper , we will make the experiment as a mostly measure , take the pmma as a research object , an optical technique to observe the solicitation and spread of high polymer under creep in real time on line 本文以实验为主要手段，以pmma为研究对象，采用显微技术对高聚物蠕变条件下的银纹损伤引发和扩展进行了实时在线观测。
