In the case of very lowelectrondensity, the energetic electron region and the runaway region emerge.
在低密度情况下出现高能电子区和逃逸区。

The amyloplast usually possessed a larger, very lowelectrondensity starch grain which mainly was long shuttle and there were some higher electron density partition or wedge structure in it.
它的基质很少，多含有呈长梭形的、电子密度非常低的淀粉粒，并有一些电子密度较高的条带结构。

The results show that formation of the precursor radicals and the growth mechanism in ICP-CVD with high electrondensity are different from those in conventional CVD with lowelectrondensity.
