氢的

26Ldquo;The atomic weight of oxygen is 16 times as heavy as that of hydrogen.

氧的原子量是氢的16倍。（或译为：氧的原子量比氢的大15倍。

As compared with the pressure of carrier gas, the subatmospheric pressure is more favourable condition to atomize the hydride, so the atomization temperature was lower (about 650℃).

由於硒化氢的原子化是在负压下完成的，它将比常压或载气压力下更有利於氢化物的原子化，因而使硒化氢原子化的最佳温度降低。

We also try to give a new definition about the AGB stars. We may refer TPAGB stars as homology AGB stars and the second ignition of hydrogen is an appropriate criterion of the HAGB, since after the second ignition of hydrogen, AGB stars have similar properties and structures: a degenerate CO core covered by double thin burning shells.

我们还尝试着给出一个有关AGB星的新的定义，即可以将热脉动AGB星称做相似AGB星，把恒星是否经历氢的第二次点燃看作恒星是否处于相似AGB的判据，因为在氢的第二次点燃之后，AGB星具有相似的性质和结构：一个简并的碳氧核上面覆盖着两层很薄的燃烧壳层。

Till now, the most used method for storage of hydrogen in array of SWNT's is by physisorption inside the SWNT's and on the outer surface of the SWNT's or in the interstice between SWNT's.

到目前为止，在单壁碳纳米管阵列中贮存氢的最常用的方法是通过虹吸作用或电化学作用使氢物理吸附在单壁碳纳米管的内部、外表面上或者单壁碳纳米管之间的间隙中。

Adsorption and reaction of H〓 and nitrobenzene on the catalyst had been studied by FT-IR method.

除了成本较高外，传统的用于混合碳四馏分加氢的贵金属催化剂的选择性也很难提高，本文研究了Cu-Co-Ce／Al〓O〓催化剂的混合碳四馏分加氢除炔性能，这在国内还没人涉足，国外有关研究也较少。

The differences of these catalysts reactivity were related to their structures and the activity of lattice oxygen.

这一方面是因为氢的引入使表面的氧物种发生了变化，形成了活性更高的氧物种，另一方面是因为氢的引入加速了氧分子向晶格氧转化。

Generally, the main point of this thesis rests with exploring novel hydrothermal methods to synthesize functional stannate composite oxides nano-materials, and studying the formation and morphology controlled mechanism of the composite oxides nano-materials under hydrothermal conditions. The main research achievements are summed up as follows:(1)According to the testing needs of photocatalytic hydrogen-generation, we have designed and set up a suit of photocatalytic H2-generation equipments with external light irradiation.

本文正是在这一背景条件下，重点研究以水热法合成锡酸盐纳米光催化材料，并对合成出的样品进行了细致的表征分析，初步研究纳米材料的光催化活性，探索纳米催化剂的颗粒尺寸、形貌和晶体结构对催化性能的影响规律，其内容主要包括以下几个方面：(1)根据光催化制氢的需要，设计并组建了一套外置光源照射的光催化制氢装置。

It's found that th e activation of alloy was improved with increasing the concentration,temperature and immersing time of alkaline solution,the reason is that the Zr-rich surface of alloy was conversed to Nirich surface because of the strong erodent action of alkaline solution,this catalyzes ...

实验发现：储氢合金电极的活化性能随碱液浓度增大、温度升高以及浸泡时间的延长得到改善，主要由于KOH的强腐蚀性使合金表面由富Zr层转化为富Ni层，为氢的吸附离解起到催化作用，总结出最佳KOH处理液的实验参数：6mol/L、80℃、浸泡 2 4h ，在此条件下合金电极循环两周即达最大放电容量。

Different from the primary pyrolysis procedure of pyrrole with the complex tautomers the initial precursors of the major pyrolysis products are simple and the corresponding pathways are more distinct.

与吡咯热解初期的形成的复杂异构体不同的是，吡啶热解的主要产物前驱体相对单一，热解产物为母体脱氢的吡啶自由基、母体脱氢开环链状自由基和母体直接开环的产物。

This paper introduces the studies of Gerhard Ertl, who is awarded the Nobel Prize in Chemistry 2007, in adsorption of hydrogen on metal surfaces, the mechanism of catalytic reaction in Haber- Bosch process for synthesis of ammonia, and the process of catalytic oxidation of CO.

格哈德·埃特尔的重要贡献主要有3方面：(1)解决了氢原子是如何在Pd、Pt和Ni等金属表面组织排列的问题；(2)对哈伯一博施法合成氨反应催化机理的研究；(3)对C催化氧化的研究及非线性动力学理论的建立。1 氢在金属表面吸附的研究萨巴蒂埃因发现精细金属颗粒催化有机物加氢的方法而获1912年度诺贝尔化学奖。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
