Phytase mainly comes from plant and organism, phytase of plant belongs to 6-phytase and it s optimum pH ranges from 5.0 to 7. 5. Plant phytase can not function effectively in monogastric animals and it is not rich in plant. So research direction about phytase is turned to Aspergillus niger which is rich in acid phytase.

植酸酶主要来自于植物和微生物，来源于植物的植酸酶均属于6—植酸酶，最适pH范围在5.0—7.5，不适合在单胃动物中起作用的，而且在植物中含量极低，因此植酸酶的研究方向转向最适pH值为酸性、酶含量较高的丝状真菌。

Biodiesel is a renewable fuel consisting of the alkyl monoesters of fatty acids which are products of the transesterification of vegetable oils or animals fats with a simple monohydric alcohol in the presence of a suitable catalyst.

生物柴油是一种可再生能源，它是由植物油或动物脂肪与短链醇类在适当的催化剂作用下转酯化反应生成的脂肪酸单酯组成的。生物柴油作为一种可替代、无毒、生物降解性好和可再生性燃料，越来越受到人们的重视。

The engine main circuit have to be gurranteed drawing the torque of electric motor and rotation speed wholly to do regulateing of independence ,But also possess extensive setting range SS7's mould electric locomotive adopts Quan Kongqiao and semi bridge accuseeing series connection to make up the monophase bridge style commutation electric circuit ,The coil power supply is encouraged against the stringtrain by the electric motor the drawing armature to 3 parallels operation ,Still there is an excitation commutation bridge ,He encourages the coil power supply with 3 electric motors drawing together to the series connection ,Moreover has one another accuses the regulating action .

机车主电路必须保证牵引电动机的转矩和转速都可作独立的调节，而且要有宽广的调节范围。SS7型电力机车采用一个全控桥和一个半控桥串联组成单相桥式整流电路，向3台并联工作的牵引电动机电枢与串励绕组供电，还有一个励磁整流桥，向串联在一起的3台牵引电动机他励绕组供电，并具有相控调节作用。可以实现机车无级调速和无级削磁。SS7型电力机车采用再生制动方式，再生制动时，牵引电动机作直流发电机工作，并且将电能馈送回接触网，此时电力机车相当于一个移动的发电站。

Four different ionic liquids, BF4, BF and PF6 were investigated, arid PF6 showed the best effect when used as the reaction media, giving the highest yield in the shortest reaction time. Promoted by KF in PF6, N-aryl or N-alkyl monosubstituted sulfonamides could react with various activated halides and unactivated primary halides smoothly. Reactions were performed at 85℃ for 2~10 hours, and thirteen N-alkylation products were obtained with 70%~97% yields. Moreover, the ionic liquid recovered could be reused for three times with no appreciable decrease in yield and reaction rate.

结果表明，以PF6为反应介质时显示出了最好的效果，反应的时间最短，收率最高。N-芳基或N-烷基单取代的磺酰胺和各类不同结构的活化的卤代烃和未活化的一级卤代烃在PF6中KF作用下，85℃反应2~10h，以70%~97%的优良收率得到了13个N-烷基化产物，而且离子液体回收使用3次后效果未降低。
