The results of the experiment show that menadiol sodium diphosphate has no mutation effects on the procaryotic cell in vitro.

结果 当甲萘氢醌二磷酸酯钠的浓度在0.5、5、50、500、5000μg/皿，无论加或不加S9混合物时其对4株沙门菌株的回复突变作用均为阴性。结论甲萘氢醌二磷酸酯钠在体外对原核细胞无诱变作用。

Both the and DtV$ for the glycyl dipeptides increase with increasing molality of sodium acetate. The interactions between charged center or glycyl units of the peptide and ions dominate those between alkyl groups of the peptide and the ions. The interaction between the peptides and sodium acetate is mainly pairwise. The results were interpreted successfully by the cosphere overlap model.

结果表明：甘氨酰二肽的标准偏摩尔体积和标准偏摩尔转移体积均随乙酸钠浓度的增加而增大，溶液中离子与肽带电基团/甘氨酰基团(CH2CONH)之间的相互作用大于离子与肽的非极性基团间的相互作用，乙酸钠和甘氨酰二肽之间主要是对相互作用。

The existing form of boron on the rubbing surfaces is sodium metaborate which can be dissolved in water. The hydration water of so- dium metaborate can reduce the aiitiwear function on Four-ball Machine but enhance its antiwear ability on Timken Tester. The study also revealed that sulfonate dispersant Can reduce the antiwear function of sodium metaborate while succinimide dispersant enhance its antiwear ability.

结果表明，含偏硼酸钠的白油能在摩擦表面形成含偏硼酸钠的表面膜而具有较好的抗磨性，硼在摩擦表面膜中以偏硼酸钠的形式存在，钠和钙的石油磺酸盐型分散剂会降低偏硼酸钠的抗磨性，而丁二酰亚胺类分散剂则能提高其抗磨性。

A series of crosslinked sulfonated polys were synthesized from 4,4'-difluorodiphenyl sulfone, 4,4'-biphenol, 3,3'-disulfonate-4,4'-difluorodiphenyl sulfone and 1,3,5-trihydroxy benzene by nucleophilic substitution polycondensation reactions. The trifunctional crosslinker of THB was in the mass fraction range of 3%-7%.

以4，4'-二氟二苯砜、4，4'-联苯二酚、3，3'-二磺化－4，4'-二氟二苯砜二钠盐和三羟基苯为原料，经高温溶液缩聚反应，制备了一系列不同磺化度的新型交联磺化聚芳醚砜。

所述组合物也可以包含微晶纤维素、交联羧甲纤维素钠、无水乳糖、硬脂酸镁、微粒化的含水乙二胺四乙酸钙二钠和微粒化的硫代硫酸钠五水合物。

Typical precipitatingagents that have been used include sodium or calcium hydroxide , iron sulfide , sodium dimethyldithiocarbamate, sodium hydrosulfite , and starch xanthate.

典型的沉淀已使用的药物包括钠或氢氧化钙，铁硫醚，二甲基二钠，亚硫酸钠，淀粉黄原酸酯。

It was shown that these two strains both can utilize benzoate as sole carbon source and the maximum tolerance of benzoate are 1.7% and 1.600, respectively; These two strains both can grow on benzene, toluene, xylene, phenol, benzyl alcohol of as sole carbon source. Pfluorescens PFO1 can degrade dianiline, 3,5-dinitrosalicylic acid, p- dimethylaminobenzaldehyde while P. aeruginosa ATCC27853 can utilize 3,5-dinitrosalicylic acid, p- dimethylarninobenzaldehyde.

结果表明，两种菌都能在以苯甲酸钠为唯一碳源的基础培养基上生长，并且，对苯甲酸钠的耐受性分别达到1.7％和1.6％；两种菌都能以适当浓度的苯，甲苯，二甲苯，苯酚，苯甲醇为唯一碳源生长；荧光假单胞菌能以二苯胺，对二甲氨基苯甲醛，3，5-二硝基水扬酸为唯一氮源生长；铜绿假单胞菌能以3，5-二硝基水扬酸，对二甲氨基苯甲醛为唯一氮源生长。
