查询词典 imide

Molecular rearrangement reaction occurs during the foaming and post-treatment forming hexahydric imide ring. The prepared PMI foams have closed cell structure with the cell size ranging from 0.5mm to 0.7mm and have a good thermostability with the characteristic degradation temperature at about 221.5℃.

在发泡和热处理过程中分子链发生分子重排反应，生成六元酰亚胺环结构；PMI泡沫为闭孔泡沫塑料，泡孔平均孔径在0.5~0.7mm之间；制得的泡沫塑料热稳定性好，热分解温度在221.5℃左右。

Compounds which possess active hydrogen atoms, include those which contain hydroxyl, carboxyl, mercapto, primary and secondary amino groups, carbonamido, sulphonamido, and reactive methylene or imide groups.

化合物具有活性氢原子，包括那些含有羟基，羧基，巯基，小学和中学氨基，carbonamido，sulphonamido，和活性亚甲基亚胺或团体。

The inhibiting rate of natural antigene oligonucleotide was also only 25％ with the similar treatment. Compared with the natural oligonucleotides, the inhibitions of mdrl gene expression by the naphthyl imide-conjugated oligonucleotides were enhanced as much as two times.
