The snail was found to have an indirect developmental type in the early development. The fertilized eggs were oval-shaped and discoidal cleavage. Embryonic development stages were divided into cleavage, blastula, gastrulae, trochophore, and intra-membrane veliger. Larval development stages included veliger, late veliger and crawling larvae metamorphosed to juvenile.

Observing the mature embryo sac of the mutant: It was found thatthe embyo sac appeared in typical polygonum type and more than 90% of the embryo sac hadintegral inner structure. They had egg apparatus, two polar nucleus and three antipodal cells , and their position in the embryonic sac was normal .

幼穗分化、成熟胚囊观察发现，90％以上的胚囊具有完整的内部结构，有卵器、两个极核及多个反足细胞，且位置正常，胚囊呈现典型的蓼型结构；同时还观察到雌、雄器官的发育是同步的。

METHODS: A computer-based online search of PubMed database was undertaken to identify related articles about the microcapsulated cell or encystation material for treating diabetes mellitus published from 1980 to 2009 by using the key words of "microcapsulation, islet, transplantation" in English. Meanwhile, we search CNKI for relevant articles published between 1999 and 2009 with the same key words in Chinese.

检索PUBMED数据库中1980/2009有关人工细胞微囊技术进展在糖尿病中应用的文献，检索词"microcapsule， islet， transplantation"，并限定文献语言种类为English；同时检索中国期刊全文数据库1999/2009有关人工细胞微囊技术进展在糖尿病中应用的文献，检索词为"微囊，胰岛，移植"。

The electrical activities and sequences of oesophagus, reticulum and the four compartments of rumen in sheep were recorded with polygram system RM-6008 during rest, feed, rumination and eructation.

用RM-6008型记录仪记录了绵羊在安静、进食、反刍和嗳气等状态下的食管、网胃和瘤胃的前背囊、后背盲囊、后腹盲囊、前腹囊的电活动及其先后次序。

Results MRI findings of central neurocytoma are specific in 5 cases. The ganglioglioma was found in the tempora and occipital lobe in 7 cases,in the brainstem in 1 case, cystic-solid tumor was observed in 5 cases with extramural nodule in 3 cases, obviously thickened gyri were revealed in 1 cases and central necrosis in 2 cases.The 3 cases of Lhermitte-Duclos disease include the specific molecular layer imaging features.

结果 5例中枢神经细胞瘤有一定的MRI特征，3例诊断正确。8例神经节细胞胶质瘤中，7例位于或主要位于颞、枕叶，1例位于桥脑和延髓，表现为囊实性者5例，实性部分位于囊外的有3例，呈实性表现为局部脑回增厚者1例，囊变坏死明显者2例。3例小脑发育不良性节细胞瘤有特征性的条纹状或分层状表现。

Toreniafournieri. has a naked embryo sac that protrudes from the micropyle into the cavity between the funiculus and placenta. As embryo sac is mature, the egg cell, the two synergids and about half the central cell are located outside the micropyle.

蓝猪耳在其发育的四核期，胚囊从珠孔端伸出，当胚囊完全成熟时，助细胞、卵细胞和大部分中央细胞均暴露于胚珠组织之外，是研究被子植物受精和胚囊发育的模式植物。

Dongying wild soybean seedlings had the highest activities of antioxidant enzymes and higher Na+ transport efficiency under the short-term NaCl stress, which helped to alleviate the damage of the short-term NaCl stress.(4) The shape of chloroplasts was changed to circular from oval, and the granum stacks twisted under the short-term NaCl stress in the Shandong cultivar soybean leaves whereas, only twisted granum stacks were observed in the Dongbei wild soybean leaves.

4NaCl短期胁迫后山东栽培大豆幼苗叶片的叶绿体形状发生变化，由椭圆形变成了圆形，类囊体结构部分膨胀扭曲；东北野生大豆幼苗叶片的叶绿体形状没有多大变化，但是类囊体结构部分膨胀扭曲；而东营野生大豆幼苗叶片的叶绿体形状和类囊体结构都几乎没有变化。

In Hangchow it has four generations each year and the time of its occurrence is well synchronized with that of the scale.

根据测定，隐斑瓢虫对日本松干蚧各虫态的捕食能力较强，一头成虫的日平均捕食量为：显露若虫13.33头，雌成虫4.27头，卵囊3.67个(每个卵囊内平均有卵265.5粒)，雄蛹28.27只；一头幼虫全期(或2—4龄和3—4龄)分别能捕食显露若虫39.20—105.56头，雌成虫40.80—47.79头，卵囊39.38—41.79个，雄蛹220.50只。

Because of the vesicle's impenetrability, the rod segments exert an inhomogeneous entropic pressure on the vesicle and induce a change of the vesicle shape.

由于囊泡膜对刚棒的几何空间限制，减少了刚棒的活动空间，其构象熵减少，因此对囊泡膜表面施加不均匀的熵致压力，导致刚棒锚泊囊泡的形状变化。

Because of the vesicle\'s impenetrability, the rod segmentsexert an inhomogeneous entropic pressure on the vesicle and induce a change of the vesicle shape. The interaction between the rod segments and the vesicle membrane exerts an extra tension to the membrane.

由于囊泡膜对刚棒的几何空间限制，减少了刚棒的活动空间，其构象熵减少，因此对囊泡膜表面施加不均匀的熵致压力，导致刚棒锚泊囊泡的形状变化。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
