The vibration can increase the material turbulivity, and mostly avoid the stratification.
振动力使物料湍流度加大，使物料分层不易形成。
2
Wind-protection effect, turbulivity and soil moisture are the main factor which determine the falling dust capacity.
防风效能、乱流交换强度、土壤湿度是决定降尘量大小的主要因子。

It is significant to find optional method for keeping the face velocity uniformity of FFU and reducing the face velocity turbulivity of FFU, furthermore, to keep the cleanliness level under FFUs.
