portunus meaning in Chinese
梭子蟹属
Examples
- Microstructures and ultrastructures of y - organ and mandibular organ in portunus trituberculatus
大颚器显微及超微结构研究 - Part iii comparative studies on the morphology and ultrastructure of compound eyes in two kinds of crustacean . the morphology and fine structure of compound eyes in two species ( portunus tritubereulatus , metapenaeus ensis ) were studied by electron microscope
三、几种不同分类地位甲壳动物复眼超微结构的比较用电子显微镜观察了三疣梭子蟹( portunustritubereulatus )和刀额新对虾( metapenaeusensis )的光感受器。 - Portunus , trituberculatus the spermatogonium exist in two different forms , the second form comes from the first one . during spermatogenesis , chromatins condense at different level . the nucleus changes into homogeneous since middle spermatid stage , and the nucleus extends into the radial arm
三疣梭子蟹在生精细胞阶段，染色质不同程度的浓缩凝集；在精细胞阶段，核质呈均质状，形成薄壁的圆球形核杯，部分核质延伸入辐射臂内。 - There is no thumb - shaped area on the back of the compound eye . the results under transmission electron microscope show that the fine structure of the compound eye in portunus tritubereulatus is different from that in metapenaeus ensis . the former has eleven retinular cells which composed the compound eye
两部分的小网膜细胞在结构上基本相同，都含有线粒体、多囊体、内质网、色素颗粒等，但是上部的小网膜细胞没有扳膜体，而且胞质比较致密，膜下储泡囊的空腔较小，里面有膜状结构。 - We observed the surface structure and inner structure of the compound eyes . and we also studied the change process of the ultrastructure of the compound eyes in different light adaptation . comparative studies on the structure differences of photoreceptor between portunus tritubereulatus and metapenaeusensis were also done
运用电子显微镜技术观察了三疣梭子蟹( portunustritubereulatus )的光感受器的超微结构，对三疣梭子蟹复眼的外部形态、大小、内部超微结构，以及在不同光适应条件下的变化过程进行了研究；并且与刀额新对虾( metapenaeusensis )光感受器的超微结构进行了比较。
