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。

In this part, the densities of sodium benzoate, sodium nitrobenzoate, sodium chlorobenzoate and sodium methylbenzoate in DMFwater mixed solvents have been measured at 298.15K with an Anton Paar Model 55 densimeter. From these densities, apparent molar volumes and partial molar volumes have been calculated, transfer volumes from water to DMF-water mixtures and substituent contributions to the transfer volumes have also been obtained. Solvent and substituent effects are discussed in detail. The Scaled Partical Theory has been applied to the ternary solutions to evaluate the partial molar volumes of cavity formation and the volumes change associated with solute-solvent interaction.

选择了含有取代基团的芳香类有机电解质，主要是苯甲酸钠、硝基苯甲酸钠、氯苯甲酸钠和甲基苯甲酸钠的邻、间、对同分异构体作为研究对象，用DMA 55型振荡管密度计测定了它们在不同质量百分数组成的DMF-水混合溶剂中的密度，利用这些密度数据，计算了表观摩尔体积和偏摩尔体积，得到了这些单取代苯甲酸钠从水到DMF-水混合溶剂中的迁移偏摩尔体积及苯环上不同位置的取代基对迁移偏摩尔体积的贡献值，讨论了溶剂效应和取代基效应，并将定标粒子理论应用于此三元电解质溶液中。

Was founded in 1993, after reorganization of assets in 2003 as "phosphide", more than 500 million fixed assets, the existing 150 staff, of whom technical staff of more than 20, are specializing in the production of phosphate (sodium pyrophosphate, disodium hydrogen phosphate, sodium hexametaphosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate) enterprise.

河南省焦作市磷化实业有限公司（原武陟县兴璋化工有限公司）建于1993年，后经2003年资产重组为&磷化&，公司固定资产500多万，现有职工150人，其中技术人员20多名，是专业生产磷酸盐（焦磷酸钠，磷酸氢二钠，六偏磷酸钠，磷酸二氢钾，磷酸氢二钠，磷酸三钠）企业。

Compared with other antiseptic,SDA can make food have non-harm,fresh,good taste,long stire,low price etc merits.

称双乙酸钠与其它防腐剂相比，经添加SDA的食品，具有无毒、鲜美、口味纯正、储存期长、价格地、低等优点，特别是既没有山梨酸钾的异味，又没有丙酸钙的涩味，更没有苯甲酸钠的怪味，又因为双乙酸钠为钠盐，不会影响食品的绵软。1/3-1/2量的双乙酸钠抑菌效果与丙酸钙相当，与等量的梨酸钾防腐效果相当，但价格极为低廉。

Compounds produces a spectrum having a bright yellow double line by noticing ① that there is no such line in the spectrum of light when sodium is not present ,② but that if the smallest quantity of sodium be thrown into flame or other sources of light ,the bright yellow double line instantly appears.

钠特有的物理现象，然后通过 by 结构从·反正两方面补述得出此结论的实验过程，也就·是说，这个复合句通过连接词和形态变化把三·大层意思连接起来，先结果，后叙事，其语序①·②③几乎与汉语的表达习惯相反。因此，只有·如果把少量的钠投入火焰或其它光源中，·会立即出现一道金黄色的双线；当钠不存在时，光谱中这条线就消失了。由此我们知道，钠或钠的任何化合物所产生的光谱都带有一道金黄色的双线。
