Theorem 1 Suppose the function is differentiable at,then its partial derivative at exist, and the total differential of

定理1如果函数在点可微分，则该函数在点的偏导数必定存在，且函数在点的全微分为。

If all of the partial derivations exist and only one of them is not continuous,the multivariate function is differentiable.

It is found that there exists an obvious prepeak in the low-Q domain (Q=15.7 nm^-^1) of the structure factor. In the X-diffraction pattern, the liquid diffraction curve is corresponding with the solid diffraction curve. There exist the prepeaks for them in the low-Q domain, which shows that there is the comparability in the microstructure between them.

采用紧束缚原子间作用势，利用分子动力学模拟的方法研究了Al5Fe2合金熔体的微观结构，发现在结构因子的小角部分(Q=15.7nm^-^1)出现了一个明显的预峰，并得到X射线衍射实验的进一步印证，在实验测得的合金衍射图样中，液态衍射曲线与固态衍射曲线间存在着很好的对应关系，它们在小角部分都存在峰位，这表明Al5Fe2合金熔体与其固态在结构上存在着很大的相似性。

Diglossia describes a situation in which two very different varieties of language co-exist in a speech community, each with a distinct range of purely social function and appropriate for certain situations.
