同时，也为进一步建立岩体结构合理的损伤演化方程、本构关系和研究岩石破坏机理提供了科学依据。

At the same time, some scientific hypotheses of the damage evolution equations and stress-strain relationship as well as the failure mechanism of rock mass are also proposed.

这理论表明，本构方程完全确定物质流形的几何结构。

This theory shows that the constitutive equations determine entirely the geometric structure of the material manifold.

然后由得到的平衡方程、热传导方程和本构方程建立了两种不同本构模型的粘弹性杆热-结构耦合问题的数学模型。

Then we can get the math model of the two kind of constitutive models' heat-mechanics coupling problem by using the balance equation, the heat exchange equation and the constitutive equation.
