支鏈

The crystallinity of polyethylene decreased with increase of content of short branched chain methyl. 聚乙烯隨著短支鏈甲基含量的增加,結(jié)晶度降低。

Poly(methyl methacrylate) branched chain in MG molecule structure was destroyed when thermal and oxygenous aging. MG分子結(jié)構(gòu)上的顯著變化是聚甲基丙烯酸甲酯支鏈破壞,熱穩(wěn)定性取決于接枝物結(jié)構(gòu)及其熱性能。

Objective: Effect of branched chain amino acid (BCAA) on protein metabolism was studied in exercised rats and mice. 目的:探討在運(yùn)動(dòng)狀態(tài)下,支鏈氨基酸(BCAA)對(duì)大鼠和小鼠蛋白質(zhì)代謝的影響。

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
