mixed grafting
解釋
混合嫁接-
As to the high - density polyethylene, two strategies were performed : ( 1 ) after being modified by grafting polar groups on its backbone, polyethylene and organic montmorillonite were melt mixed directly, which could obtain the polyethylene / montmorillonite nanocomposites. the effect of groups grafted on the backbone on the efficiency of intercalation was investigated in this paper ; ( 2 ) choosing the grafters obtained in this experiment as the compatilizers, polyethylene / montmorillonite nanocomposites had also been prepared by melt mixing the polyethylene, grafter and organic montmorillonite. the difference of grafters and sequence of mixing on the intercalation result had also been analyzed
對于高密度聚乙烯，採用以下兩種思路進行： （ 1 ）對聚乙烯首先進行功能化改性，使聚乙烯分子鏈上接枝上不同的極性基團，將改性后的聚乙烯再同有機蒙脫土直接熔融復合，成功的制備了聚乙烯蒙脫土納米復合材料，並考察了接枝到聚乙烯主鏈上基團的不同對最終插層效果的影響； （ 2 ）選用制得的接枝物作為相容劑，將聚乙烯，接枝物，有機蒙脫土三者熔融復合，也可以得到聚乙烯蒙脫土納米復合材料，並對選用不同的接枝物作為相容劑以及復合順序對最終插層效果的影響加以分析。 -
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。
