查询词典 hydrogen arsenide

Each starch reagent has its own mode of action on mineral surface, such as primary starch mainly by hydrogen bond, cationic starch by the co-action of hydrogen bond and electrostatic force (for minerals with negative charge on its surface), while carboxymethyl starch, hydroxamic acid starch and dialdehyde starch principally by chemical force accompanied with hydrogen bond and electrostatic force in part. Such chemical forces ensure the close adsorption of reagent on diaspore surface and enforces the hydrophilic of mineral surface. Also the branched chain enable the starch to cover the collector adsorbed on mineral surface, so as to depress diaspore furthermore.

不同淀粉药剂在矿物表面表现不同作用，原淀粉主要是氢键的作用，阳离子淀粉是氢键和静电力的共同作用，羧甲基淀粉、羟肟酸淀粉和双醛淀粉离子性药剂与矿物间的作用除了氢键、静电力外，更重要的是与矿物表面金属离子间产生的化学作用，使药剂能牢固地吸附在一水硬铝石矿物表面，增加矿物表面的亲水性，同时，淀粉支链结构的存在，使它能够掩盖吸附的捕收剂，达到抑制一水硬铝石的目的。

Hydrogenases are key enzyme for bio-hydrogen production, most of them were rapidly inactivated by oxygen. It is important to bio-hydrogen production and hydrogen application that improve the O2-tolerance of hydrogenase.

氢酶是生物制氢的关键酶，大多数氢酶因对氧极敏感而易失活，因此提高氢酶的氧耐受性对生物制氢有重要意义。

The analysis of hydrogen-producing nature was presented through the point of catalysis of hydrogenase, the production of energy and its transportation. From author's view, the course of de-hydrogen from pyruvic acid to acetyl-CoA was the chief determinant for hydrogen producing. And the balance and adjustment of NADH/NAD〓 was just the necessary condition, not the foundation reason.

本文从产氢反应的催化体系、能量产生和传递等不同角度对产氢本质进行了系统的理论分析，认为产氢发酵的第一判定条件（即产氢发酵的充分必要条件）是丙酮酸-乙酰CoA脱氢过程；而NADH／NAD〓的平衡调节机制只是必要条件，不是产氢发酵的根本动力。
