查询词典 selective

METHODS: 24 rabbits were divided into four groups: control group; rapid pacing group; adenosine perfusing group; selective adenosine receptor antagonist perfusing group. The index of observed: time of repolarization in monophase action potential (APD90); the active level of A1 adenosine receptor; the level of free calcium in the atrium cells and the ability of atrium cell to release calcium.

新西兰白兔24只，随机分为4组：①对照组：常规克氏液灌流，②腺苷灌流组：灌流液中加入2umol/L的腺苷，③心房快速起搏组：常规克氏液灌流+心房快速起搏，④腺苷受体拮抗剂干预组：克氏液+DPCPX（100nmol/L）灌流+心房快速起搏；观察指标：①起搏前后心房肌单相动作电位复极时间的变化；②起搏组和对照组的心房肌腺苷A〓受体活性对比；③心房肌细胞内游离钙含量以及氯化钾激动后钙释放能力对比。

The analytical results have shown that p ro ducts mainly consisted of some monosubstituted, disubstituted and a few trisub stituted naphthalenes. Except the low activity of HZSM-5 catalyst, all other z eolite catalysts have higher activity. HY and Hβ catalytic activities were the highest, and their naphthalene conversions attained to 79.12 and 55.79 percent respectively, but their selectivities for 2-isopropylnaphthalene, 2,6-diisopropylnaphthalene(2,6-DIPN) and 2,7-diisopropylnaphthalene ( 2,7-DIPN) were too low. ZM catalysts had good activity and much better selecti vity, especially for ZM4-3, of which its 2,6-DIPN/2,7-DIPN ratio was 2.97. Th er efore, some zeolite catalysts are recommended for shape selective isopropylat ion of coal tar naphthalene.

研究结果表明，煤焦油萘异丙基化产物主要由一取代萘、二取代萘以及少量三取代萘组成；除HZSM-5活性较低以外，其它催化剂均有较高的反应活性，其中HY和Hβ反应活性最高，萘转化率分别达75.15％和55.96％，但β位产物的选择性较差；ZM类催化剂既有一定的活性，又有较高的β选择性，是萘择形异丙基化反应理想的备选催化剂。

As a kind of low-priced nonmetallic mineral, zeolite has good selective adsorption ability for NH4＋-N. Modifying can even increase this capacity.
