It was observed that the influence of bud and its position on the healing process of grafting unions using hardwood sectioning method, and found that:(1) bud of a scion and its position to the graft unions have no influence on callusing formation of the isolation layers, and the early differentiation of cambia;(2) a scion bud closer to the grafting union would promote the formation of more compacted callus cells and the earlier formation of callus bridges;(3) conduit differentiation in grafting unions of lower-bud scions was later than that of other treatments.

利用滑动切片法对芽子有无及芽位对嫁接愈合过程的影响进行了观察，发现：(1)接芽有无及芽位对隔离层及愈伤组织形成和形成层的早期分化没有影响；(2)芽或去芽的芽位距接口近，可以促进愈伤组织的紧密连接，即愈伤组织桥的形成；(3)低位芽枝嫁接体中导管分化较晚，而其它处理导管的分化几乎是同时发生的，而且导管首先出现于愈伤组织薄壁细胞中。

In order to improve the interfacial adhesion between the matrix and inorganic particles, the SiO2 nanoparticles were modified with polymethyl methacrylate and silicane couplant KH507 respectively, and then the SiO2/PVC composites were prepared via the melt blending method. The microstructure and mechanic properties of SiO2 nanoparticle filled PVC composites were investigated by FT-IR.

Tensile strength and t- ear strength increased by 119%and27.4% compared to ungraft SBR Vulcanizates; The Tg of SBR ro- se after grafting and heat-resistence ability of SBR–g–is better than u- ngrafting SBR.

在获得接枝率高而且性能良好的SBR-g-的基础上，采用动态硫化法制备SBR–g–增容丁苯橡胶/聚氯乙烯热塑性弹性体（SBR/PVC TPV），研究SBR-g-对SBR/PVC TPV的增容效果。

The main material of producing SPF is soybean dregs in which oil has been extracted. By soaking, separating, globular protein is purified from soybean dregs. Under proper condition, SPF is made by changing protein space structure and copolymerizing and grafting with hydroxyl and nitrile polymers by wet spinning.

大豆蛋白纤维的生产其主要原料是大豆榨完油后的豆粕通过水浸、分离、提纯出球状蛋白质在适当条件下改变蛋白质空间结构并与羟基和氰基高聚物共聚接枝，经过湿法纺丝制成。

Then polymer latexes coated the silica particles through carboxyl chemical bond adsorption;When the compound temperature(25℃) was lower than Tg(45℃) of polymer,latexes remained their basic shape,and silica nanoparticles adhered to the surface of latex particles.

目前国内外制备复合纳米SiO2微球的主要方法是通过硅烷偶联剂对SiO2进行预处理，使其接枝在粒子表面，然后通过乳液聚合[5，6]、溶胶凝胶法
