本文對距離法中的鄰接法進行了三點改進: 1 .使用更精確的進化模型來度量序列之間的距離，降低因模型而帶來的誤差; 2 .通過隊列產生多個拓撲結構，解決了鄰接法只能產生一個拓撲結構的缺陷; 3 .引入回退機制，消除了距離法中負枝長的產生，得到的樹更準確。Effects on properties of nr / sbr / pa66 compound of modified rubber such as enr - 50, mg49, epdm - g - mah and nr - g - mah were investigated, besides utilizing pretreated short fiber and adhesive agents, so as to improve the adhesion on the surface between rubber and short pa66 fiber. first, mah grafted nr was made by myself using brabender plasticord from south china university of technology, while other modified rubber was procured from certain organizations
重點研究了環氧化天然橡膠（ enr - 50 ） 、甲基丙烯酸甲酯接枝天然橡膠（ mg49 ） 、三元乙丙橡膠接枝馬來酸酐（ epdm - g - mah ）及順酐化天然橡膠（ nr - g - mah ）等改性橡膠對sfrc性能的影響。Preparation, structure and properties of hdpe ~ g ~ aa / mmt nanocomposites melt grafting reaction of hdpe with aa was performed in thermohaake rheomix and hdpe - g - aa with high grafting degree and high grafting efficiency was prepared. the change of torque indicated that the graft copolymerization was existed during melt compounding. the extent of grafting was analyzed by ftir and element analysis
在hdpe中只加過氧化二異丙苯（ dcp ）時，由於發生交聯反應而使平衡扭矩明顯增加，熔點和結晶度降低，加入aa后， aa與hdpe的接枝和hdpe自身的交聯並存，前者對後者有抑制作用，從而使扭矩下降，熔點和結晶度部分恢復。Emphasis is laid on the new methods of post - functionallization in terms of plasma graft copolymerization, supercritical carbon dioxide graft copolymerization and solid state mechanical chemical graft copolymerization, and some renovations to the traditional post - functionallization in terms of solvent graft copolymerization, radiation graft copolymerization and solid phase graft copolymerization
