Thus the growth of diamond single crystals seems to be disturbed either by too high hydrocarbon supersaturation or by less atomic hydrogen or by a decreasing surface mobility of the growth species. 因此,金刚石单晶体的生长看来既受到太高的碳氢超饱和度的影响,也受到少量原子态氢的影响,还受到生长物质表面迁移率减小的影响。
It is known that the efforts of chemists of the last century established as a fundamental fact the extreme solidity of the atomic structures, which go to make up the ninety-two known chemical species. 大家知道,上个世纪的化学家们的研究确立了这么一个基本事实――原子结构极其稳定。这种性质有助于合成99种已知的化学元素。
Because only atomic hydrogen has that set of lines which means I could then take the spectra of gas phase species and use that information to identify. 我在这抬头看看然后离开,那就是氢原子,那就意味着,我可以测定,气相种类的光谱并且运用那个信息来鉴定。
Ion mass spectrometry ( IMS) is based on the fact that charged atomic and molecular species are ejected from the surface of a condensed phase and separated according to their charge to mass ratio. 离子质谱按照物质电离后质量与电荷的比值(即荷质比m/e)大小进行分离,可以测定离子的质量和离子流的强度[1]。
In this paper, we used flame atomic absorption spectrophotometry to determine the contents of Ca, Mg, Fe, Mn, Cu and Zn in 7 species of algae. 本文采用火焰原子吸收光谱法测定了七种藻类植物中钙,镁,铁,锰,铜,锌六种元素的含量。
And the break of the bonds between Ru-Ru and the formation of atomic Ru were observed, which can partly explain the experimental facts that oxidizing reaction was accelerated after induction period as soon as oxidation species were formed. 同时,作者也观察到Ru-Ru之间的化学键发生断裂,形成具有原子活性的自由Ru原子,这可以部分解释一旦氧化物种形成,经过一诱导期后,氧化反应会加速进行的实验事实。
Atomic Absorption Detector Coupled With a Gas Chromatography and Its Application in Analysis of Organo-tin Species 气相色谱与原子吸收联用及其在有机锡化合物形态分析中的应用
The adsorbed atomic oxygen is the common oxygen species for both ethylene epoxidation and combustion; molecular oxygen plays no direct role in either two reactions. 氧在表面存在三种吸附态,其中原子态吸附氧是乙烯环氧化和深度氧化的活性物种,分子态氧对两个反应不起直接作用。
The Effect of Discharge Temperature upon Atomic Species in Plasma Nitriding of Steel Surface 等离子体金属表面氮化中放电温度对氮原子态粒子的影响
Ln recent years, the aforementioned states have been obviously improved by developing a new kind of technique: MCs+-SIMS, i. e. detection of MCS+ molecular secondary ions instead of respective M ± atomic species under CS+ primary ion bombardment. 近几年来,上述状况已经通过一种新技术开发得到明显改善,这就是MCS+-SIMS技术,即在CS+一次离子轰击下检测分子型二次离子MCS+而不是M±。
When Ag/ Sn atomic ratio is lower than 0.20, the main silver species is silver oxide existing in both dispersed state and crystal phase, and all the corresponding catalysts show relatively large surface areas and high catalytic activities. Ag/Sn原子比低于0.20的样品中,银物种为分散态氧化银及晶相氧化银,这些样品具有较高的比表面和催化活性;
The flame atomic absorption spectrometry ( FAAS) was used for determining 7 trace element in 3 cherry tomato species. The content of 3 cherry tomato and the masses tomato were compared. 采用火焰原子吸收法对3个品种樱桃番茄中的钙、镁、钠、锰、铜、铁、锌7种元素的含量进行了测定,并比较了大宗番茄与樱桃番茄中以上元素的含量。
Though it is generally more computationally intensive comparing to empirical and semi-empirical formulations, first-principle method has greater prediction power since atomic species is the only necessary input information to start a calculation. 这种计算方法相比经验和半经验公式的计算量更大,但第一性原理计算具有更强的预测能力。
The effect of different adsorption-site and adsorption of different atomic chain species on spin-polarization transports are discussed in our work. 讨论了原子链吸附位置的不同以及不同磁性质的原子链的吸附对石墨纳米带自旋极化输运的影响。
Atomic internal motion of electrons can produced light the internal electron motion that is not same with the species, which was resulted in a different light area. 原子内部电子运动产生了光波,内部电子运动随着物质种类的差异也不一样,从而产生不同的光波。
