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。
The fundamental characteristics of movement of density flow are similar with those of the saline wedge.
盐水与泥沙异重流的基本运动特性是相类似的。
