In order to improve the hydrogen storage properties of Ti2 alloys, over stoichiometry of A side and partial substitution of Mn by transition metals were adopted, and the hydrogen storage properties of Ti2(x=1.0, 1.1; M=V, Fe, Ni, Cu) alloys were investigated.

为改善Ti2AB2型合金的储氢性能，采用A侧过化学计量和过渡金属部分替代Mn进行多元合金化，系统研究了Ti2(x=1.0， 1.1； M=V、Fe、Ni、Cu)合金的储氢性能。

Unexpectedly the vanishing magnetic cubic anisotropy in Permalloy is found to be independent of its atomic structure but depends only upon the stoichiometry of Fe and Ni in the Fe_x Ni_(1-x) alloy. This new observation is further investigated and confirmed by first principles electronic band calculations, which helps to understand the long-standing issue why Permalloy should be a soft magnet.

我们发现立方磁晶各向异性能(K_1)消失这个Permalloy的软磁特性跟具体晶体结构无关，只取决于化学组分，第一性原理能带计算也验证了这一实验结果，从而有助于理解为何Permalloy很软这个长期未解决的问题。

Theoretical analysis and experimental results indicate that reaction of zinc with selenide as fully as possible under H2-O2 flame at about 1500℃ is the key step in the synthesis process and prolonging holding time at high temperature, which makes the diffuse reaction adequately take place, is favourable to obtain stoichiometry ZnSe polycrystalline.

理论分析和实验研究均表明：前期H2-O2焰下高温灼烧(~1500℃)使Zn和Se充分反应，是合成工艺的关键；延长后期恒温时间（不少于2周），使扩散反应进行完全，有利于获得更接近化学计量比的ZnSe多晶料。

There are some defects that leave the stoichiometry unaffected.

有一些缺陷是离开了化学计量关系造成的。

A compound has stoichiometry and ion distribution opposite to that in one of the structures just mentioned.

化合物的计量关系及其离子分布和刚才提到的结构恰好相反。

The ratio of air to fuel for which perfect combustion takes place is called stoichiometry.

实现完全燃烧时的空气和燃烧的比率称为化学当量比。

It is showed by calculations that solid carbon appeared only when stoichiometry is less than 0.4 under equilibrium state.

模型中还考虑了非理想气体对燃烧的影响。

Stoichiometry of leaf N and P is a characteristic of plant to adapt to environment, and can provide data for process-based modeling at large scale.
