查询词典 selectivity

The results show that the developing sensors exhibit high sensitivity and selectivity due to high sensitive and selective electroreduction of PB for H2O2 at low potential and fast response and higher stability of the sensors are attributed to biocompatible microenviroment provided by the silica sol-gel and the 'sandwich' construction maintaining the enzyme activity.

研究结果表明：由于PB在低电位下对H_2O_2的高选择及高灵敏电催化还原，使得制备的酶电极具有高灵敏性和好的抗干扰性。

Electrosynthesis is a new method for preparation of αalanine. There is few reference about it, but electrosynthesis has a high selectivity and a high current efficiency. In addition, the operating condition is mild, and the reaction process is easy to be controlled.

有关电化学法合成α—丙氨酸的文献仅有两篇，虽然这方面的研究很不充分，但是电合成法避免了剧毒物质的使用，操作条件温和，通过选择电极材料、电极电位和电流密度等电化学参数，能够控制合成发应的进程，而且电合成可以具有很高的选择性和电流效率。

Its mechanism is the use of anthraquinone in alkali conditions off proton surface forming 10 more stable carbon anion face, but because carbon anion and oxygen ion exist between testosterone and enolate type each other changes, cause reaction product complex, at least five, reaction selectivity, product yield, separation difficulties, and product purity is not high, therefore, using the type and quantity of alkali, phase transfer catalyst type, solvent, to optimize the selection process conditions so as to improve the yield target product.

其机理是利用蒽酮在碱存在的条件下脱去氢质子面形成10位较稳定的碳负离子面进行，但是因为碳负离子和氧负离子之间存在酮式和烯醇式的互变，导致反应复杂，产物至少有五种，反应选择性差，产物分离困难，产率低，且产品纯度不高，因此，利用对碱的种类和量的多少，相转移催化剂的种类，反应溶剂的选择，来优化反应工艺条件从而提高目标产物的产率。
