支链
The crystallinity of polyethylene decreased with increase of content of short branched chain methyl. 聚乙烯随着短支链甲基含量的增加,结晶度降低。
Poly(methyl methacrylate) branched chain in MG molecule structure was destroyed when thermal and oxygenous aging. MG分子结构上的显著变化是聚甲基丙烯酸甲酯支链破坏,热稳定性取决于接枝物结构及其热性能。
Objective: Effect of branched chain amino acid (BCAA) on protein metabolism was studied in exercised rats and mice. 目的:探讨在运动状态下,支链氨基酸(BCAA)对大鼠和小鼠蛋白质代谢的影响。
Branched chain amino acids and ketone amino acids contents both were increased (P< 0.05). Ser and Gly contents both were lower than normal (P
