幼体

The biomass of zooplankton changed relatively intensely, especially Cladocera、Copepoda and Young animal, and the biomass of the zooplankton will gradually increase.

随着泥沙的逐渐沉降，浮游动物生物量变化相对激烈，尤其是枝角类、桡足类和无节幼体，水中浮游动物生物量将逐渐增加。

布氏田鼠嗅觉通讯的行为发育----幼体对群体气味的辨别。

In addition,20 samples of copepoda resting eggs were separated from the pond mud in Decemeber,2003,and 5 samples of nauplins hatched from that kind of resting eggs were detected.

在20例桡足类休眠卵样品中有1例为阳性，阳性率为5%；并且实验室中孵化此种休眠卵得来的桡足类幼体样品中检测到阳性，阳性率为40%。

It showed adult copepoda could carry active WSSV particle and led to shrimp infection potentially.

另外从带毒桡足类所产的休眠卵及其孵化的幼体中也检测到WSSV阳性，显示桡足类休眠卵极可能是传播WSSV的载体和途径。

In this study, copepoda and its resting eggs in shrimp culture ponds were detected using PCR dot-blot hybridization and nest-PCR for the presence of WSSV. The results showed that WSSV positive cases were detected in copepoda from egg to adult, and the positive copepoda appeared earlier than cultural shrimp in ponds.

1。本研究利用PCR-斑点杂交和巢式PCR法检测野外发病对虾养殖池塘中桡足类及其休眠卵，以及由这些休眠卵孵化出的幼体携带病毒情况，发现桡足类由卵到成体各阶段中均有阳性个体，而且池塘中在春天放养对虾苗前桡足类就出现阳性个体。

Newly hatched larvae known as nauplii Daphnia morphology similar to that after four times after the camp molt parasitic life.

刚孵化的幼虫称为无节幼体，形态与水蚤相似，经过4次蜕皮后开始营寄生生活。

Larvae of this species fail to undergo metamorphosis, so the adults remain aquatic and gilled.

由于美西螈幼年时未能进化，所以成年后还保有幼体水栖和外腮的特征。

The disease caused by helminthes is called .

在吸虫生活史中，进行幼体增殖的虫期是、。

The development of schizochroal eyes in phacopid trilobites is a good example of post-displacement paedomorphosis. The eyes of immature holochroal Cambrian trilobites were basically miniature schizochroal eyes.

一个很好的关于裂膜眼发展的例子来自于Phacopid三叶虫的幼体发育的加快取代期，在处于这个阶段的该三叶虫的眼睛上，显示了一组寒武纪全膜眼三叶虫的形态。

European eels are inferred to spawn year-round from otolith analysis, but the smallest, recently hatched leptocephali are found only in late winter and spring.

耳石分析得出欧洲鳗是全年产卵的，但是最小的刚孵化出来的柳叶鳗幼体趋势在冬末春初发现的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
