纳精囊

It was found that there was an obvious cytochemical changes in the epithelium and in the luminal contents of the spermatheca during different phases of the vitellogenesis cycle.

目的在于揭示纳精囊与卵巢发育周期的关系，为受精生物学的研究提供理论依据。

Female crabs were collected from Ningguo County in Anhui Province on May 1994.The results showed that morphology of the spermatheca is associated with the ovarian cycle.

但是，有关十足类甲壳动物纳精囊在繁殖过程中不同阶段的形态学、组织学和细胞化学方面的研究尚未见报道。

A study on spermatheca of the freshwater crab,Sinopotamon yangtsekiense was performed with histologic and cytochemical metheds.

纳精囊是溪蟹雌性生殖系统的重要组成部分，在精子储藏、受精及排卵过程中起着十分重要的作用。

365Nm UV can penetrate into the spermatophore and the thelycum crust to infure the sperm.

5 nm波长紫外线能够透过精荚和纳精囊盖，对其内精子起到杀伤作用。

First we investigated the relationship between the female pleonal expansion and female reproductive condition (i.e., non-ovigerous, ovigerous, or with spermatophores) to clarify the morphological characteristics of female coconut crabs that were able to mate.

首先，我们调查了雌蟹腹变宽和生殖条件的关系（非抱卵蟹、抱卵蟹、或者纳精囊中出现精荚）来确认椰子蟹具有交配能力的雌蟹形态特征。

Farther, the sperm DNA of wild male was extracted from copulated wild female thelycum in three families of the ten.

从其中3个家系的雌性亲虾纳精囊中提取了雄虾精子DNA，微卫星标记显示各家系的子代个体均有一个等位基因与雄性亲虾的基因型相符，且符合孟德尔遗传规律，这为野生中国明对虾雌虾在繁殖季节一对一的繁殖行为提供了遗传学的证据。

It belongs to the same genus level to South American white leg shrimp P.

南美蓝对虾属于开放型纳精囊种类，其繁殖顺序是：蜕皮→成熟→交配→产卵。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
