Being the stress diffusionphenomenon in the concrete structure, the model is further revised.
针对模型中混凝土斜腹杆斜向传递压力时的应力扩散现象，进一步修正了该模型。
2
Because the smaller the settling of particles is, the more serious the diffusionphenomenon is.
因为颗粒越小沉降越慢，而扩散现象则越严重。

In the interaction of two communities, the technique spreads phenomena occur frequently. The change characteristic of the diffusionphenomenon is decided by the intrinsic growth rate.
