脱水

The use of DSZ, since it is an industrial solid waste, found out a way for the comprehensive utilization of it, which helps minimize pollution and attain the goal of treating wastes by using wastes. The flocculated matter is dewatered by filter-press and then mixed with coal for fuel without creating the problem of second-time pollution, Therefore this method is both economic and reational.

活性炭吸附的流程处理淀粉废水的方法是可行的；所用的DSZ为工业废渣，解决了DSZ的综合利用问题，减少了污染，达到以废治废的目的；絮凝物经压滤脱水后掺在煤中做燃料，无二次污染问题；该方法经济合理。

According to the Box-Benhnken design principle,the method of response surface method with 3 factors and 3 levels was used. The factors influencing the technological parameters were determined by means of regression analysis. Response surfaces were finally graphed with the yield as the response value. The synthesis conditions were optimized as follows:reaction reagent was NBS,stoichiometric proportion between NBS and anhydrovinblastine was 1.07; the dosage of TFA was 22 mL/L; reaction temperature was －68 ℃ and duration was 90 min.

在单因素实验基础上，根据Box-Benhnken实验设计原理，采用三因素三水平的响应面分析法，研究了各个因素及其交互作用后，得到了合成7′-Br-脱水长春碱的最佳工艺条件：以二氯甲烷为溶剂，采用NBS为溴代剂，其用量与底物的物质的量比为1.07∶1，TFA的加入量22 mL/L，在－68 ℃下反应90 min，终止反应后，得到卤代产物。

The conversion of alcohols to alkyl halides was investigated using acidic ionic liquid X as halogenating agent, acidic catalyst as well as medium. The reactions of primary alcohols gave very satisfactory conversions and selectivities except for the substrates with lower boiling point,such as n-octanol and benzyl alcohol. They obtained the corresponding halides with almost quantitative yields(95%-100%).The secondary alcohols also gave the corresponding halides with excellent conversions, however, the by-products of dehydration were detected.

伯醇除某些低沸点底物外，都以高转化率(最高达100％)和高选择性(最高达100％)转化为相应的氯代烃、溴代烃和碘代烃，例如正辛醇、苯甲醇，在X中进行卤代反应得到令人满意的结果，无论氯代、溴代还是碘代得到卤代产物的收率一般都很好华东师范大学化学系01级博士学位论文(95十100%)，极少有重排产物及脱水产物被检测出来。

Dewatering is seldom used as an intermediate process unless the sludge is to be incinerated.

脱水很少被用作一种中间的处理，除非是泥浆要被焚化。

Objective:To study the differences in the types of cerebral infarction,blood coagulation function and outcomes between the infracted patients with and without diabetes mellitus.

目的：探讨脑梗死合并2型糖尿病与单纯脑梗死之间的血脂水平、凝血功能及预后的差异。方法：将70例脑梗死合并2型糖尿病病人设为糖尿病组，62例单纯脑梗死病人设为非糖尿病组，两组均给予相同的抗凝、抗血栓、脱水、降压和改善微循环等治疗。
