Conventional cells, including ones used onboard the space shuttle and in some prototype automobiles, obtain the electrons for their electron flow by pulling them off of hydrogen atoms.

包括宇宙飞船和某些样品汽车所用电池在内的常规电池，都是从氢原子中取得电子，以此来获得产生电流所需的电子。

The amyloplast usually possessed a larger, very low electron density 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。

Scanning electron microscope indicated that adherent cells showed shuttle shape or multiple Angle shape, and the multiple apophysis showed irregular shape.

扫描电镜观察，黏附细胞为梭型或多角型表现，并有多个突起呈不规则形状。
