The density of mitochondrial, the density of the surface number and average cross section in the experiment group showed great distinction compared with the model group(P<0.01).

用药组的线粒体体密度、面数密度和平均截面积与模型组相比差异有非常显著意义（P< 0 0 1 ）。

You take the flux, multiply it by the cross section, average it, integrate it over the whole volume.

你拿流量乘以横截面，平均它，乘以它除以总容积。

Algal growth rate is different with average velocity, water depth and cross-section width.

藻类的生长速度因各断面的流速、水深和水面宽的不同而不同。
