According to above three aspects , the thesis studied the method in which sod is abstracted from aloe and the natures of sod , in order to understand completely the elements of aloe and establish base for the application and gene colony . the result is as follows : 1 separate and purify first , cut the clean leaves of the aloe into pieces and put tris - hcl buffer cob in and mash up , abstract it and highly centrifuge 基于以上三方面的原因，本文探讨了从芦荟中分离纯化sod的方法并对其基本性质进行了研究。一方面为了更彻底地了解芦荟中的成分；另一方面为芦荟中的sod的应用、基因克隆奠定基础。现将研究结果报告如下： 1
The different ratio and dosage of composite surfactants were researched about the polymer latex ' s stabilization and structure . these copolymers and homo - polymer blend to prepare self - structure gradient film . to prepare the functionally gradient materials ( fgm ) of polysilane - polyacrylate , the method of emulsion mixture was performed 各种均聚物、共聚物膜的水滴接触角显示，单体tris的含量越高，膜的水滴接触角越大，这也表明共聚物的表面能随tris的含量呈梯度变化。
However for the closed stomata , induced by aba , the distribution density of particles in gcv is greatly reduced with the obviously enlarged volume , b ) buffers regulate ph of in vitro gcv sap in the tip of micro - capillaries : certain amount of buffer ( mes - tris ) is filled from the tip of micro - capillaries beforehand , and the ph of gcv sap that is sampled by the same micro - capillary sh ould be regulated by the buffer 观察结果与本试验室已发表的气孔开放过程的实验结果一致：开放态气孔保卫细胞液泡所含颗粒状物的线度极小(平均直径10nm ) ，且分布密度极高，而经aba处理的关闭态气孔保卫细胞液泡所含颗粒状物的线度很大(平均直径50nm ) ，分布密度很小。
The different ratio and dosage of composite surfactants were researched about the polymer latex ' s stabilization and structure . afterwards , the emulsion polymerization of tris , mma , and p ( mma - co - ptris ) were carried out . some different monomer ratio copolymer latex and homopolymer latex are prepared by emulsion polymerization used self - made organosilicone monomer - [ tris ( trimethylsiloxy ) silyl ] propylmethacrylate and mma 用ir ， tem ， dma ，水滴接触角测试等方法表征所制备的均聚物和共聚物膜发现：采用有机硅表面活性剂与十二烷基硫酸钠复配使用，用量在6 8 (相对单体量)可得到粒径分布均匀且稳定的均聚和共聚乳液。
