推证了含沙水流在水轮机中流动时，其沙子和液体的流动属于分离流动，即沙子和液体的运动速度和运动角是不相同的，且沙子质量越大，差值越大；并指出在水头相同时，水中含沙时水轮机的效率一般低于清水时的效率；进而分析了水轮机各过流部件的泥沙摩损规律。

The result of immobilization showed that hydrophile membranes were more advantageous than hydrophobe ones to act as immobilization carrier. Crosslinking organophosphorus hydrolase by glutaraldehyde on polyethersulfone membrane is a simple and practical immobilization method. An appropriate amount of bovine serum albumin and crosslinker is necessary to get a good result of immobilization. In the biodegradation of methyl-parathion through enzyme membrane reactor, the effect of immobilized enzyme amount, flow rate of peristaltic pump, pH of the feed, and the methyl-parathion concentration on biodegradation rate was studied. It was shown that the biodegradation rate increased with immobilized enzyme amount and substrate concentration. Biodegradation rate didn't increase when the folw rate of the peristaltic pump was larger than 7 ml/min.
