dimensional homogeneity

The paper introduced the principle of dimensional homogeneity and π theorem and put forward the mean of dimensional analyses method in the physics teaching. Some examples were discussed by dimensional analyses method in the mechanics teaching.

简述了量纲分析方法中的量纲齐次原则和π定理，指出了量纲分析方法在物理教学中的意义，通过几个实例探讨了量纲分析法在力学教学中的应用。

The results show that this process greatly decreases the slumping and distortion of tungsten heavy alloy, increases the homogeneity of the microstructure and local hardness, etc, because of the formation of three dimensional rigid net backbone with tetrakaidecahedron in the solid state sintering stage.
