活性基团 meaning in English
active group
Examples
- Chitosan - nylon composite membrane with two active group ( - nh2 and - oh ) had a hydrophilic surface and good blood compatibility , so it can be widely used in affinity separation
其中尼龙壳聚糖复合膜具有胺基和羟基两种活性基团、良好的亲水性能、较佳的血液和生物相容性，可广泛应用于亲和微滤。 - Silane coupling agent ( kh - 560 ) with active groups was used for the treatment on silica particles in this article . the surface of silica which was treated in the way of chemical bonds was changed from hydrophilication to amhydrophilication
本文采用具有活性基团的硅烷偶联剂( kh - 560 )对二氧化硅粒子进行了表面改性，使二氧化硅颗粒表面由亲水性变为亲油性。 - The surface - modified magnetic nanoparticles have been widely used in biological and biomedical areas such as immobilization of biomolecules ; separation of metal ions , cells , proteins , dna ; immunoassay , biochemical analysis and magnetic resonance imaging ( mri ) probes
其中的壳结构既具有生物适应性，又具有可键合生物分子如细胞、蛋白质、酶、抗体和核酸的活性基团，而核具有磁性特性。 - In this paper , the author introduces another experimental research on dpf regeneration , which has been conducted by spraying h2o2 into the filter . it features that the temperature at which the soot oxidizes properly by the reaction between carbon and highly active radical species generated from h _ 2o _ 2 become much lower
本文采用了一种新的方法对柴油机微粒过滤器的再生进行了试验研究，即利用h _ 2o _ 2分解产生的活性基团和碳烟进行反应，从而在较低的温度下将碳烟烧掉。 - Consequently , with increasing mmt content , the tensile strength and young ' s modulus of hdpe - g - aa / mmt nanocomposites increased , while that of hdpe / mmt composites decreased . moreover , the addition of mmt to hdpe - g - aa decreased the melting temperature and the degree of crystallization of the matrix . these changes may be attributed to high interfacial adhesion between hdpe - g - aa matrix and exfoliated clay , which reduces the mobility of crystallizable pe chain segments , and subsequently reduces the crystallization ability
研究结果表明： mmt在hdpe中不能达到纳米级分散，而在hdpe - g - aa中， mmt能以插层型利剥离型的结构存在，这主要是由于极性的丙烯酸接枝在hdpe上提高了后者的极性，而且能与mmt上的活性基团进行化学反应，从而提高了pe链进入mmt层间的可能性，使mmt在基体中达到纳米级分散。
