However, the bands of PVDF crystalline changed synchronously with the bands of cyclohexanone during the gelation process.

此外，1695 cm~(-1)吸收峰的出现可能是C=O与CF_2相互作用而导致，表明溶剂参与了PVDF的凝胶过程。

We also discussed this unusual reaction process and proposed a reasonable "one method,two paths" mechanism.These novel iodine-mediated oxidative cycloadditions provide a rapid and efficient route to the preparation of a variety of spiro dihydrofuran and cyclopropane derivatives.

该反应不使用昂贵的催化剂；反应过程中不使用有毒有害的有机溶剂，对环境友好；反应时间短，收率高；在相同条件下得到不同结构的产物，这提供了一种新型的合成二氢呋喃和环丙烷结构的环化反应。

Just like the overseas, at present, the chloroform are mainly used to produce HCFC-22 and it shares 70% total consumption; in medicine industry, the cyclopropane are used for extraction and animal remedy anesthetic etc.

在我国，二氯甲烷主要用作溶剂、清洗剂及三醋酸纤维胶片的原料。

In the vacuum dispersing kettle air bubble and solvent vitalization shall be restrained, deaeration of materials shall be accelerated, dispersion efficiency shall be enhanced.

物料在真空容器内分散，减少了气泡和溶剂的挥发，加速了物料脱泡，提高了分散细度。

Neither noise level nor carbon monoxideexposure significantly correlated with hearing loss, while beingin the solvent-exposed group (highest decile of solvent indexvalues) was associated with statistically significant increasedrisk.

噪声级和一氧化碳曝光极大关联了与听力丧失，当是时在''溶剂暴露了小组(最高的十分位数溶解的索引价值)同增加的统计地重大联系在一起风险。

A method of aqueous phase separation for recycling oil from Spent Bleaching Earth in grease decolor was introduced in the paper.

废漂土中回收油通用的方法有蒸汽压榨法、溶剂浸取法和水相分离法等。

This standard is applied to crude paraffin which is made of raw material with oil paraffin and is diaphoresised or de-oiled not by decolor.

本标准适用于以含油蜡为原料，经发汗或溶剂脱油，不经精制脱色所得到的粗石蜡。

Commonly used in gas adsorption, separation and purification, solvent recovery, sugar, oil, glycerine, decolorant drugs, drinking water and refrigerator deodorizer,滤毒agents in gas masks, or metal salts can also be used as a catalyst catalyst carrier.

常用于气体的吸附、分离和提纯，溶剂的回收，糖液、油脂、甘油、药物的脱色剂，饮用水及冰箱的除臭剂，防毒面具中的滤毒剂，还可用作催化剂或金属盐催化剂的载体。

The Java brucea oil extracted by organic solvent has more pigment. The effects of decolorizer kind, decolorizer amount, decoloring temperature and decoloring time were studied.

传统溶剂法提取所得到鸦胆子油色泽较深，含有较多的色素，本文考察了脱色剂种类、脱色剂用量、脱色温度、脱色时间对鸦胆子油脱色效果的影响。

The results show that, using trioctylphosphane oxide or hexadecylamine as ligand, all of precursor ［In(η5-C5H5)］ decomposite and form the indium nanoparticles.

利用十六烷基胺或氧化三辛基膦配位体的作用，前驱体均可分解得到铟纳米颗粒；而在HDA相对含量高、溶剂中不含水和在紫外线照射作用下，前驱体分解反应产物为铟纳米线。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
