The conversion of alcohols to alkyl halides was investigated using acidic ionic liquid X as halogenating agent, acidic catalyst as well as medium.

2以酸性离子液体X兼作卤代试剂、反应介质和酸性催化剂，研究了醇转化为卤代烃的反应。

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。

The in situ FTIR spectra suggest that DHAA exists stably in ionic liquid, but hydrolyzes in water solution.

现场红外光谱结果表明，DHAA在水中迅速发生水解反应，而在EMIMBF4中则较稳定。

When microwave energy impinges upon body tissue, part of it is absorbed and converted to heat due to ionic conduction.

当微波能量冲击时人体组织的一部分，它是吸收和转化为热量由于离子传导。

When radio frequency energy impinges upon your body tissue, part of it is absorbed and converted to heat due to ionic conduction.

当无线电频率能量影响到你身体组织的一部分，它是吸收和转化为热量由于离子传导。

In ionic detergent s, the hydrophilic property is conferred by the ionized part of the molecule.

在离子洗涤剂中，亲水性是由分子的离子化部分而来。

The cured material has very low ionic contents with low outgassing, which is well suitable for use in electronic encapsulating, such as cover glass bonding of CCD/CMOS area image packages.

固化后材料具有很低的阳离子组成和低的排气率，因此该C- UV 4111非常适合于电子封装，例如玻璃基板上的 CCD/CMOS面元的封装。

The results demonstrated that the passivated CNT FET was capable of determining the ionic concentration of aqueous solution under an additional voltage for inducing the separation of charges.

实验结果证明这个上光阻的奈米碳管电晶体能藉由外加的闸极来分离溶液中的电荷并以此来区分出离子的浓度差别。

根据圣pachomius体力劳动组织作为一个重要组成部分寺院生活；以来，这是一个原则的和尚，作为有别于乞丐，该机构应自支撑，对外工作的这种或那种已一个必然的一部分，生活至今。

In order to study the effects of parametrical rolling on the ship movement and tilts, in allusion to ship's navigating in regular following waves, the equation of ship rolling motion is transformed into normal Mathieu equation by proper variable replacement when strong parametrical excitation in restoring moment varied according to sine or cosine wave.

为研究参数横摇对船舶运动和倾覆的影响，通过对船在规则波上随浪航行时，恢复力矩中出现的1个以正余弦规律变化的强参数激励项进行适当的变量置换，将船舶的横摇运动方程转换成标准形式的Mathieu方程。
