The separation of neutral macrocyclic calyx [4] pyrroles with 1-butyl-3-methylimidazolium chloride as background electrolyte in acetonitrile was carried out by nonaqueous capillary electrophoresis.

建立了以1-丁基－3-甲基咪唑氯盐离子液体为背景电解质，非水毛细管电泳分离中性大环化合物八甲基杯[4]吡咯、四环戊基杯[4]吡咯、四环己基杯[4]吡咯的方法。

Firstly, MESH equation was established by means of phase equilibrium of each component. Simultaneously, with a view to the strong nonideal liquid phase of alcohol－water－benzene system, M－H EOS state equation was used to determine gas phase fugacity and heat enthalpy. And relaxation method was applied to compute the composition of ternary components on each theoretical tower plate.

The non-potable water expansion tank shall be of drawn steel construction. It shall have a Butyl diaphragm separating the air chamber from the water containing chamber.

非饮用水膨胀罐应该采用拉制钢结构，应该采用丁基合成橡胶隔膜将气体腔与水腔隔离开来。

A simple,rapid,sensitive and accurate RP HPLC for simultaneous determination of ketamine, phenobarbitone and atropine in plasma was established.

本文采用ZorbaxC8色谱柱，甲醇－磷酸盐缓冲液（69∶31）为流动相，220nm为检测波长，非那西丁为内标，建立了同时测定人血浆中氯胺酮、苯巴比妥和阿托品浓度的反相高效液相色谱法。

Single component and multi\|component of iron system colloidal catalyst \Ali\|Bu\-3CH\-2CHCH\-2Cl\ were mixed by different ratios in hydrogenated gasoline medium at 25℃.This paper studied the relationship between the nonaqueous systematic electroconductivity and the concentration of catalyst components.In combination with Tyndall effect,polymerization experimental results,Ali\|Bu\-3 existed in associated state and dissociated into ionpair.The reaction between Ali\|Bu\-3 and Fenaph\-2 was the main reaction which formed colloidal core.Ali\|Bu\-3 reacted on CH\-2CHCH\-2Cl and Ali\|Bu\-2Cl was yielded which joined the formation of active center on the surface of colloidal core.The excessive Ali\|Bu\-3 was dissociated into ionpair which formed double electrode layer,and the double electrode layer kept the colloidal particles relatively stable.

研究了在25℃加氢汽油介质中，铁系胶体催化剂［Fenaph2Ali-Bu3―CH2==CHCH2Cl］单组分、多组分按不同配比混合，非水体系电导率与浓度的关系，结合Tyndall效应，聚合实验结果，得出Ali-Bu3以缔合状态存在并解离成离子对它同环烷酸亚铁的作用是形成胶核的主要反应，与氯丙烯反应生成的氯化异丁基铝，在胶核表面参与形成活性中心由过量Ali-Bu3解离的离子对形成的双电层结构，使胶粒保持相对稳定。
