The efficiency of adsorption and removing Poliovirus 1(PV1) and bacteroides fragilis phage by nature and modified sand in the conditions of different environment pH, various mental salts and concentration variation, exist of humic acid in tap and distilled water were studied in this paper.

分别在不同pH、含有不同金属阳离子及腐殖酸的脱氯自来水与蒸馏水中，研究了砂与金属氢氧化物修饰砂吸附与去除Polivirus 1(PV1)和Bacteroides fragilis phage的不同效果。

For low molar ratios of Al/Zr, a hypsochromic shift of the initial catalyst absorption band, corresponding to the monomethylation of the catalyst, was observed. Further addition of AlEt2Cl was accompanied by a continuous bathochromic shift of the maximal wavelength corresponding to the formation of more dissociated ionic active species. Then, there would be a coordination of monomer to the ionic active species.

结果表明，无论是AlEt_2Cl还是MAO，少量的助催化剂首先使催化剂发生单烷基化反应，主催化剂金属中心的最大吸收峰波长发生蓝移，而当助催化剂量进一步增加时，金属中心的最大吸收峰波长红移，单烷基取代的催化剂被大量的助催化剂夺去电子成为缺电子的阳离子活性中心，以便烯烃单体的配位插入。

The invention relates to a preparation and purification method of bicaudal gemellus quaternary ammonium salt type cationic surfactant.

本发明涉及一种双尾双子季铵盐型阳离子表面活性剂的制备及纯化方法。

In the same time, water-soluble bidental phosphines ligand BISBIS sulfonated 2,2''-bis(diphenylphosphinomethyl-1,1''-biphenyl was synthesized, and water-soluble rhodium complex Cl was synthesized in situ. This complex which was used as catalysts to catalyze the hydrogenation of avermectin was also tested. Although the rhodium complex containing bidentate phosphine BISBIS showed a higher catalytic activity than one containing TPPDS, the selectivity for ivermectin was lower. How to improve the selectivity will be needed to studied in futur.

同时我们用磺化的2，2''-二-- 1，1''--联苯，以及它们的水溶性威尔金森型铑配合物和环辛二烯的阳离子铑配合物，在利用这些配合物作催化剂，考察它们在各种反应条件下对阿维菌素的选择加氢，由于反应条件以及复合催化剂体系的组成还需要进一步优化，虽然双齿膦配合物显示了较高的活性，然而选择性还有待进一步提高。

Cation and anion effects on permeation amount of 2,2＇-bipyridyl through the molecularly imprinted polymer membrane was investigated respectively.

分别考察了阳离子和阴离子对印迹膜渗透模板分子的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
