氯甲烷

Dichloromethane was distilled from calcium hydride before use.

二氯甲烷是由钙氢化物蒸馏之前使用。

TPD experiment was conducted to measure the activation energy for dichloromethane desorption.

主要研究了金属离子改性活性炭对二氯甲烷脱附活化能的影响。

Although the market share of the dichloromethane exported from the United Kingdom to China was in a decreasing tendency in China, this decrease was caused due to the sharp increase of the consumption quantity in China market.

虽然英国对中国出口的二氯甲烷在中国的市场占有率呈下降趋势，但这是由于中国市场消费量快速增长造成的。

In some embodiments compounds described by the formula CCl.sub.xH.sub.y comprise carbon tetrachloride, dichloromethane, or combinations thereof.

在某些实施方案中，由化学式CClxHy所表述的化合物包括四氯化碳、二氯甲烷或它们的组合。

In this method, ethyl acetale and dichloromethane were used to extract residues with eddy-oscillate method.

用二氯甲烷，采用匀浆法提取，并用安捷伦的C18柱（500 mg；6 mL）进行净化。

Dichloromethane was used as the solvent and selected optimal extraction conditions were selected and adopted.

选择二氯甲烷为溶剂，λmax=272nm，参比油浓度C_1和C_2分别为45mg·1~(-1和350mg·1~(-1左右，工作曲线测量范围为45—300mg·1~

This solution is then treated with either methylene chloride or ethyl acetate, which bonds with the caffeine.

这个解决方案，然后处理或者二氯甲烷或乙酸乙酯，这些债券咖啡因。

Then the solution is heated to the temperature at which the caffeine and either methylene chloride or ethyl acetate compounds evaporate.

那么，解决办法是加热温度的咖啡因，或是二氯甲烷或乙酸乙酯化合物蒸发。

European or Traditional Process - Direct Method: The direct process involves softening the beans by steam first, then washing them for about 10 hours with either a methylene chloride or ethyl acetate solution to absorb the caffeine from the bean.

欧洲或传统工艺-直接方法：直接过程涉及软化咖啡豆的蒸汽，然后洗涤他们大约10小时带有二氯甲烷或乙酸乙酯溶液吸收咖啡因的咖啡豆。

And the operational condition was as follows: 100-200 mesh silica gel to be the stationary phase, solvent system of methlene chloride: ethyl acetate: ethanol = 80:35:5 to be the eluent, the flow rate of the eluent to be 2.0 mL/min, the feeding concentration of pristinamycins to be 2.26 g/L, the total loading amount of the silica gel to be 0.81 mg/g and the temperature to be 25℃.

优化后的柱层析操作条件为：选用100～200目的硅胶，二氯甲烷：乙酸乙酯：乙醇=80：35：5为洗脱剂，流速为2.0 mL／min，普那霉素的进样浓度为2.26g／L，硅胶的总负载量约为0.81 mg／g，温度为25℃。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
