粗面结构是粗面岩常具有的特征结构。其特点是在偏光显微镜下看来，基质中的碱性长石微晶呈大致平行的排列，这反映熔岩凝固时的流动情况。
粗面内质网先裂解为大小不同的小泡，尔后小泡上的核糖体开始脱落，直至变成同心圆状板层结构；
At first, the RER became the different sized vesicles, then, the ribosomes on the little vesicles began to fall, and finally, the RER turned to the concentric round lamellar structures.
结构疏松，边界不清的NLB与粗面内质网和游离核蛋白体关系密切。
The NLB of loose structure was frequently associated with free ribosomes and cisternae of the rough endoplasmic reticulum.
结果部分照射后存活的细胞有超微结构的改变：线粒体肿胀、脂质沉积，粗面内质网扩张。
Results Changes in ultrastructure observed in part of the alive cells were as following: swollen mitochondria, lipid deposit, rough endoplasmic reticulum dilatation.
