The experimental results show that the transfer volumes for these amino acids from water to sodium acetate, sodium butyrate, sodium caproate, sodium caprylate and guanidium hydrochloride solution are positive and increase with the increasing concentration of denaturant The standard partial molar transfer volume of zwitterionic end group (NH〓, CO0〓) are larger positive values and the corresponding values of methylene group CH〓 are smaller and negative.

实验结果表明，氨基酸从水到乙酸钠、丁酸钠、己酸钠、辛酸钠和盐酸胍水溶液的标准转移偏摩尔体积为正值，且随变性剂浓度的增加而增大；氨基酸的两性端基的标准转移偏摩尔体积为较大的正值，而CH〓基团标准转移偏摩尔体积为较小的负值。

Values of hydration number of amino acids have been calculated at different temperature and concentration of denaturant. It is found that they decrease with increasing temperature and concentration of denaturant. Denaturant and increasing temperature have cooperative dehydration effect on amino acids.

计算了不同温度和变性剂浓度下氨基酸在乙酸钠、丁酸钠、己酸钠、辛酸钠和盐酸胍水溶液中的理论水化数，发现它们随变性剂浓度的增加和温度的升高而减小，说明变性剂和升温对氨基酸有协同脱水作用。

A new imidazolinyl intermediate is prepared from phenylacetic acid and diethylenetriamine firstly, and then they react with the solution of sodium chloroacetate into the imidazolinyl quaternary ammonium salt.

以二甲苯为溶剂，苯乙酸和二乙烯三胺为原料，经酰胺化和环化脱水合成了新型咪唑啉化合物，并用氯乙酸钠溶液对其进行改性得到了苯乙酸咪唑啉季铵盐。

SDA is widely applied to food, cereal crops and forages etc., and Sodium Dehydroacetate is mainly used in food.

双乙酸钠已广泛应用于食品、粮食谷物和饲料中，脱氢乙酸钠目前则主要在食品中使用。

The indicators measured included pH value change, NH3-N change, LAB concentration, and silage deteriorations etc during fermentation of silages.

根据青贮饲料的质量及经济成本等综合考虑，在双乙酸钠和脱氢乙酸钠各自组中选取一个最佳浓度，作为玉米青贮试验的添加剂。

A mediator-less two-chambered microbial fuel cell was constructed with sodium acetate as substrate in the anode and carbon felt as cathode. The effects of different electron acceptors in the cathode, external resistances value, concentration of sodium acetate and different inoculation ways on electricity generation by the MFC were investigated.
