重要阶段

Neurulation is an important stage in the embryo development of vertebrate, during which the ectoderm thickens into epidermal neural plate and then forms neural folds and neural tube.

脊椎动物胚胎发育过程中，神经胚期是一个重要的发育时期。这个阶段胚胎外胚层增厚形成上皮型神经板，神经板两侧隆起形成神经褶，随后神经褶两侧向背中线合拢并愈合成神经管。

The result suggests PACAP/GHRH has an important role in embryos and larvae, especially in neurula appearance stage.

结果表明，自卵受精后，均有GHRH／PACAP的表达，且在神经胚期表达量增高（约5倍）；提示PACAP在斜带石斑鱼胚胎和仔鱼发育过程中具有重要作用，尤其是神经出现阶段。

Along with serving them great results in the SERPs, provide them with some useful knowledge to help them understand why SEO is important to continue to do and not just a onetime thing.

沿着在SERPs服务他们的大目标，提供他们一些有用的知识来帮助他们理解为什么SEO持续性工作的重要，而不仅仅是一个阶段工作。

The whole embryonic developmental course results from the ordinal expression of a large number of genes according time and space. Many developmental mechanisms have been determined in the embryonic stage. Therefore, study on the regulative mechanism of embryonic development is important for elucidate principles of biologic growth, development and evolution.

整个发育过程都是大量的基因按照一定的时间、空间和次序表达的结果，其中许多调控机制在胚胎发育阶段就已经决定，因此，研究胚胎发育调控机制对于阐明生物的生长、发育和起源进化具有重要意义。

Sufficient understanding socialism is primary the otherness of level ownership structure, have important sense on theory and practice.

充分认识社会主义初级阶段所有制结构的差异性，在理论和实践上都具有重要意义。

The results indicate that female wasps deposit HMPs on the chorion of host eggs with her ovipositor near the end of egg-laying process. Na ye females do not posses the ability for recognizing the marking pheromones and have to obtain the ability though the learning process, in which the wasp inserts her ovipositor into a host egg to determine whether the egg has been parasitized followed by antennal drumming on the exterior. Once the learning process is completed, the female wasp will be able to discriminate between parasitized and unparasitized hosts and reject a parasitized egg by simply drumming on the exterior of the egg. Learning plays an important role in reducing initial rejection time when an unsuitable host is encountered. Female wasps of T. astriniae can quickly learn to associate the presence of a HMP on host egg chrion with the internal status of the egg.

研究结果表明，玉米螟赤眼蜂的寄主标记信息素是在其产卵过程中的收场阶段由产卵器产生的，并且标记在寄主卵表的化学物质；玉米螟赤眼蜂对标记信息素的识别不具有先天性，其必须先用产卵器插入寄生卵来检测是否被寄生，然后其触角不停地敲击，通过学习获得对标记信息素的识别能力，从而放弃了对寄生卵的选择，学习对初始放弃时间有着重要影响，改善了其对寄主搜索效率，这种学习行为是与寄主联系在一起学习的，它能根据寄主被寄生与否而对标记信息素作出反应与不反应。

It has wide applications and such research is becoming a hot topic. Topic partition is a significant problem during text structuring in automatic abstracting system.

The precambrian protodiwa was discoveried in China for the first time. In author's opinion, this region experienced a protodiwa staye with drastic Tectono-Magmatic Activiation Similar to the diwa region in phanerozoic thime. This achievement is an important contribution to the diwa theory.

在我国首次发现前寒武纪原地洼区，认为该区在晋宁运动后，经历了一个与显生宙地洼区相似的强烈构造—岩浆活化的原地洼阶段，对地洼学说作出了重要的贡献。
