常見例句雙語例句The dependence of amorphous polymer cohesive energy density on temperature is studied.本文對無定形聚合物的內(nèi)聚能密度的溫度依賴性進(jìn)行了研究。NaBH4 in hexane or toluene would not initiate the polymerization unless pyridine or THF was used as solvent, but an amorphous polymer was the product.四氫硼鈉在己烷和甲苯溶劑中,不易引發(fā)丙烯酸第三丁酯的聚合反應(yīng),但在吡啶和四氫呋喃中能引發(fā)聚合,亦得到非晶態(tài)聚合物。The main exception to this rule is polycarbonate, which is the amorphous polymer of choice for high quality transparent moldings, and has excellent mechanical properties.其中主要例外是聚碳酸酯,它是可選用做高質(zhì)量透明注塑件的非結(jié)晶質(zhì)聚合物,并具有卓越的機(jī)械性。 返回 amorphous polymer
