Part Ⅰ: The changing trend of G values of hydrogen peroxide in the reactionsbetween flavonoids and peroxyl radicals is an important parameter in elucidating thereaction mechanisms,γ-Irradiated aqueous solutions (saturated with 〓) andaerated ethanol solutions of several typical flavonoids were eluted through aluminacolumns and the G values of hydrogen peroxide generated in the solutions weremeasured.

第一部分：黄酮类化合物与过氧自由基反应的过程中生成的过氧化氢值的变化是解释机理的主要依据之一。

As one of the solution for petrolic oil crisis and environment protection, hydrogen blend natural gas also act as feasible way to transform vehicle fule from Conventional fuel to hydrogen gas.

天然气掺氢燃料是解决石油危机和环保问题的车用代用燃料之一，是实现从传统燃料向氢能过渡的最具可行方案。

The experts also simulated the phenomenon of natural fire in Luo Maozai's home: the phosphoreted mineral was decomposed into the gas of phosphoreted hydrogen under the condition of bacteria. The gas of phosphoreted hydrogen burns spontaneously under given conditions of moist air and then ignites the methane in the air which comes from the mouse holes.

专家组成功地模拟了罗家的&自燃&现象：含磷的矿物质在有细菌和具备还原性条件下分解成磷化氢气体，而磷化氢气体在一定潮湿的空气环境下自燃，继而引发空气中通过老鼠洞挥发出来的甲烷体燃烧。

These kosmotropes may be divided into two groups which act somewhat differently:(1) polyhydroxy compounds fit in well with the hydrogen bonding arrangements, but stabilize any cluster 'flickering' via hydrogen bond rearrangement, as their hydroxyl groups are similarly separated to water-water separations, and (2) zwitterions where the balance between hydrophilicity, hydrophobicity, anionic and cationic characteristics ensures good solubility but only weak net interactions to surrounding water.

这些kosmotropes可分为两个群体行为稍有不同：(1)多羟基化合物符合了氢键安排但任何稳定集束'摇曳'经由氢键重排，由于其羟基同样隔开水水离职，(2)氨基酸的平衡，亲水性，疏水性，阴离子和阳离子特色ensures溶解性好，但只有弱相互作用网，对周围的水。

With increasing number of hot-wall hydroprocessing reactors and extension of service time, the occurrence of polythionic acid corrosion, hydrogen induced spalling of weld overlay, temper embrittlement of base metal, hydrogen embrittlement and surface cracking etc.

随着国产热壁加氢反应器的数量不断增加和服役时间的延长，连多硫酸腐蚀、堆焊层氢致剥离、母材回火脆化、氢脆、表面开裂等时效损伤出现的情况越来越多。

In 500—1000 ℃, electronic hole conduction is dominant in dry and wet oxygen, air or nitrogen. Protonic conduction is dominant in wet hydrogen and it is about two orders of magnitude higher than that in hydrogen-free atmospheres.

在500~1000℃下，在干燥和潮湿的氧气、空气和氮气气氛中，样品以电子空穴导电为主；在潮湿的氢气气氛中，以质子导电为主，其电导率比不含氢气气氛（O2，air，N2）中的电导率约高两个数量级。

There are two parts in this thesis. Part I focuses on the transient effect in InGaP/GaAs hetero-junction bipolar transistors. Part II focuses on the P memory effect and buffer-layer-quality determination using C-V measurement in AlGaAs/GaAs pseudomorphic high-electron-mobility transistors. The characterization of hydrogen passivation for InGaP HBTs grown on semi-insulating GaAs substrates is studied. The transient effect caused by hydrogen passivation results the current gain ?

本论文分两部分，第一部份讨论在磷化铟镓的异质接面双载子电晶体中，由於氢的包覆效应产生的特性之研究，由於氢在此种元件中所造成的载子包覆现象是引起电流增益增加的暂态现象的主要原因，本论文提出一个计算氢包覆比例的模型，并与SIMS量测的结果相比对，经过几次热回火处理，此种暂态效应可以被消除。
