lethal dose (LD)

用法例句

The results show that the process uses small amount of LD catalyst,gets higher target product yield and content,thus reduces the cost production.

采用LD催化剂,优化了工艺条件,与使用二甲胺催化剂相比提高了产品含量和收率。

The influences of LD antioxidant,264 antioxidant and 2246 antioxidant on the vulcanizing characteristics,thermal oxidative ageing stability under free condition,and water extraction resistance of NR compound were investigated.

对比研究了抗氧剂LD与抗氧剂264,抗氧剂2246对NR胶料的硫化特性、自由状态下的热氧老化防护性能及耐水抽出性的影响。
