The effect of HPMC-E50 and HPMC-F50 on PVC resins in VCM suspension polymerization was analyzed based on a lot of experiments.
通过大量试验分析了HPMC-E50和HPMC-F50在氯乙烯悬浮聚合中对PVC树脂的影响，从而确定了复合分散体系的质量分数以及分散剂的配比。
Mr Rubin had bought the picture at an auction house that was unfamiliar with this kind of work and gave it an estimate of E50, 000-70, 000.
拍卖行不懂得这幅画的价值，给出5- 7万欧元的估价卖给鲁宾。
Delay in the release from the sigmoid-type HCRF-S70 is due to its larger amount of water requirement to start the nutrient release as compared to the exponential type HCRF-E50.
与指数曲线形的HCRF - E50相比较，S曲线形的HCRF - S70养分释放推迟是由于养分开始释放时所需水分量较大。
To initiate the release nutrients, a certain amount of water needs to permeate into the film-coated controlled release fertilizer, HCRF-S70 needs more water to permeate than HCRF-E50.
为了养分的开始释放，需要一定量的水分透入包膜肥料内，HCRF - S70需要透入的水比HCRF - E50的多。
