Heart malformation, such as PTA, DORV, VSD and aortic arch malformation, were detected when neural crest were taken out before they migrated into 3, 4, 6 pharyngeal gland. Interestingly, the types of malformation were related with the length of neural crest destroyed; PTA was detected if the length exceeds two somites, while DORV would be detected if the length less than two somites. These results indicate that CNCCs are very important to the conotruncal development.

研究发现，如果在迁移之前切除散发到第3、4、6咽弓的神经嵴细胞，就会出现永存动脉干、主动脉骑跨、右室双出口、主动脉弓畸型和室间隔缺损等心血管畸形，且切除的长度与畸形的种类相关，如切除长度大于两个体节可产生永存动脉干，切除长度小于两个体节则产生右室双流出道，由此可见，心脏神经嵴细胞对于心脏圆锥部的发育意义重大。

The pumpkin is an orange-colored squash, and orange has become the other traditional Halloween color.

南瓜也是万圣节的标志性象征。南瓜是橘**的，所以橘**也成了传统的万圣节颜色。

In Section 4.1 and Section 4.2, delay SEIR and SEIRS epidemic disease models with vertical transmission and pulse vaccination are discussed, respectively.

第一节和第二节分别讨论了具有垂直传染和脉冲免疫的时滞SEIR及SEIRS传染病模型。

In front lay a small parterre, planted with box and other shrubs; but thr ough this sacred division we passed only upon rare occasions indeed -- such as a first advent to school or final departure thence, or perhaps, when a parent or friend having called for us, we joyfully took our way home for the Christm as or Midsummer holy-days.

屋前有个小花坛，种着黄杨之类的灌木；但说真的，只有碰到难得的机会，才走过这块圣地，譬如头一次进校，末一回离校，还有父母亲友来接我们，我们喜洋洋回家去过冬至节，或夏至节。

After the exposure, the retinas were examined with light and electron microscope. results: under light microscope, irregular nucleoplasm and unclear border of nucleus in the ganglion cell layer were found in the experimental groups of 2 h, 12 h and 24 h. these changes were also found in the inner nucleus layer. under the electron microscope, swollen mitochondria and vacuolized endoplasmic reticulums were found in all the layers of retina in the groups of 2 h, 12 h and 24 h, most obvious in the group of 24 h. in the group of 72 h, only lightly swollen mitochondria and dilated endoplasmic reticulums were found in the ganglion cell layer of retina.

结果： 光镜：实验组中2，12及24 h组均可见视网膜神经节细胞层内细胞核出现核质不均匀，核边界不清，内核层细胞核也有同样改变；电镜：实验组中2，12及24 h组视网膜各层均出现线粒体肿大，内质网空泡样变，以24 h组最为严重，72 h组仅见视网膜神经节细胞层出现轻度线粒体肿大，内质网扩张。

Pay special attention to the final Stanzas and to the Neo-gapnist images at the end: we'll compare this ending to the conclusions of Keat's "To Autumn" and to the version of the poem as it first appeared, with the Stanzas renumbered and reorganized, in Poetry magazine

特别注意最后一节以及最后新间隙主义者的意象：我们将这结尾对照济慈〈秋颂〉的结尾部分，以及诗的第一版，对比重新编排的诗节，摘自《诗歌》杂志

It is feel pretty and magnificent , and it has a lot of radians .

到现场看到它还觉得挺壮丽的，而且他有很多弧度一节一节的。

RESULTS:In BN rat retina,Cx43 was immunolocalized to internal limiting membrane,nerve fiber layer,ganglion cell layer and pigment epithelium.Cx43 appeared in the form of distinct puncta distributed on ganglion cell.

结果：正常视网膜内界膜，视神经纤维层以及神经节细胞层明显表达，神经节细胞表达的主要位置是细胞质和细胞膜，色素上皮细胞全层表达，内外颗粒层及内外层状层无表达。

In order to study the architectuer of human cardiac neurons, the location and mumber of human cardiac ganglionated plexuses and their nervous connections were investigated.

为了研究人心脏神经元的构筑，观察了人心脏神经节的分布数量和神经连接。光镜下发现大量神经节（550±149）或神经元分布在人的心房和心室表面。

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。
