So, when the finished particle size distribution, residual moisture content, bulk density and particle shape must conform to precise standards.

因此，当成品的颗粒大小分布、残留水份含量、堆积密度和颗粒形状必须符合精确的标准时。

On the basis of the crystal size distribution (CSD) theory, the growth rates, nucleation density and nucleation rates of plagioclase have been worked out.

再根据晶体大小分布理论（CSD），计算出斜长石的晶体生长速率、成核密度及成核速率等岩浆结晶动力学参数；

The focusing properties of a space-charge lens depend on the size, shape and density distribution of its electron cloud.

空间电荷透镜的聚焦特性决定于其电子云的大小、形状和密度分布。
