grafting degree 中文意思是什麼
grafting degree
解釋
接枝度-
With increasing the content of ydh151, the grafting degree increased and the grafting efficiency decreased. however, the content of dcp cannot be added too much so as to avoid the crosslinking reaction between ydh151 and hdpe
但是由於ydh151與hdpe也會發生交聯，所以dcp的量不能過多， ydh151的量也在低於10 %為宜， ydh151含量太多時接枝效率大幅度一卜降。 -
The grafting degree and grafting efficiency were decreased. the conversion of semi - contionious emulsion polymerization was decreased as the addition of mmt was increased because of the effect of monomer diffusion and decreasing efficiency of intiating agent
半連續乳液聚合法制備abs mmt時，蒙脫土的存在使聚合轉化率顯著下降，並且mmt粘土含量越高，對乳液共聚合造成的不利影響越大。 -
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。 -
These data showed that the chimerism were specially tolerant to donor xenoantigens in skin grafting and mixed lymphocyte reaction ( mlr ) assays, however were still immunocompetent to mhc - disparate third party c57bl / 6 mouse. in the second experiment, mice of group b appeared with variant degree of wasting, diarrhea, fur losing, and all died within 15 days. pathologic changes of liver and intestine were inflamming cells infiltrating and necrotizing
肝、小腸切片均有明顯病理改變，主要表現為腸粘膜部分脫落、壞死和炎性細胞浸潤，肝實質內有灶性淋巴細胞及多形細胞浸潤，並可見局灶性壞死，兩者均符合gvhd病理改變。 -
Besides, suspension grafting of acrylamide onto polypropylene was studied in water medium. the maxium degree of grafting had archieved above 1 %
還採用懸浮接枝方法制備出聚丙烯接枝丙烯酰胺（ pp - g - am ） ，接枝率最高可達1以上。 -
The extent of grafting was analyzed by ftir and element analysis and thermal properties of hdpe - g - ydh151 were studied by dsc measurement. when adding dcp to hdpe, the melting temperature and the degree of crystallization of the matrix decreased because of the crosslinking reaction of hdpe
而且mmt的加入，降低了hdpe - g - aa的熔融溫度和結晶度，這主要是因為剝離后的mmt在一定范圍內限制了pe鏈的運動，從而降低了基體的結晶能力。
