研究中还给出了梁关键部位的应力应变全过程曲线，研究成果还与未考虑材料的非均质性的结果进行了比较。

The full curves of stress and strain at the key location of the beam are given, and the results are also compared with that of homogeneous materials.

对一组不同均质度系数下岩石材料体积效应的数值模拟结果表明，岩石强度的体积效应根源于材料的非均质性。

The results of numerical simulation on volume effect of rock material at a group of different homogeneity indexes show that the volume of rock strength results in the heterogeneity of rock material.

因此，应变梯度，因此有关梯度的力学性能有着密切的联系氢气所产生的非均质性非均匀干燥在一层的材料。

So, the strain gradients and consequently the related gradients of mechanical properties are closely linked to hydric heterogeneities generated by non-uniform drying in the layer of material.
