Compared the patient s pain,the anterior/middle/posterior-height of every operative centrum, the angle of kyphoscoliosis before and after the operation.

结果：每个椎体注入骨水泥3～6ml，平均4.12ml，术前椎体前缘高度13.04±3.72mm，中线高度15.44±5.25mm，术后椎体前缘18.41±3.77mm和中线22.48±2.88mm与术前的椎体前缘和中线有显著差异(P＜0.05)。

Most of such dendrite cores are distributed in the grains with an elliptical morphology; some of them lie in the grain boundaries with triangular or lathy morphologies. There are few dislocations and substructures in the dendrite cores, and there are clear phase boundaries between such dendrite cores and the matrix.

Ni合金过冷熔体中亚稳相和稳定相的竞争形核的计算与实验结果定性吻合，即当熔体过冷度大于某一临界过冷度时亚稳相将作为初生相从过冷熔体中析出，通过分析发现瞬态形核理论能更好的描述深过冷熔体中的竞争形核问题。

Minor Ce is found in pearlite and honeycomb ledeburite which transformed by the dendrite of primary austenite, while major Ce in ledeburite of lathy cementite type.

初生奥氏体枝晶转变形成的珠光体和蜂窝状莱氏体都含有较少的Ce，而板状渗碳体型莱氏体含Ce较多。

The main lithofacies feature of East Part rockbody contains large plagioclase,while there locally exists little(or doesn\'t exist) plagioclase-bearing lherzolite in the West Part rockbody.

东段岩体以出现大量的含斜长石岩相为主要特征，西段岩体以不出现或只局部出现斜长二辉橄榄岩异离体与东段岩体相区别。

The locomotory apparatus that emerges during the spermiogenesis consists of the multilayered structure, basal bodies, flagella and accessory structures.

精子发生过程中形成的运动器的各部分结构包括鞭毛、基体、多层结构及附属结构；基体是细胞中新形成的结构，在不同类群的蕨类植物中分别由双中心粒、分支生毛体和生毛体产生。

Strut-graft with an appropriate distraction after corpectomy plays an important role not only in regain and maintain the cervical spine lordotic curvatures but also in acquire the global immediate stability of the cervical spine. After single vertebra corpectomy, the proper range of distraction between the superior and inferior vertebra maybe among 4-6 millimeters.

中下颈椎单椎体次全切除减压后，适当高度的撑开植骨对恢复和维持颈椎曲度以及手术节段的即刻稳定性有重要作用，中下颈椎单椎体次全切除减压后支撑植骨的高度应该是在手术椎体的上位和下位椎体间高度的基础上再撑开4～6mm左右。

Compounds, including 15 new C21 steroids, were isolated from the alcohol abstracts of the ratten of Marsdenia tenacissima. 37 of them are C21 steriods and their glycosides, the rest 5 compounds are lignans.

从通光散藤茎的乙醇提取物中，共分离得到42个化合物，其中包括C21甾体及其甾体皂甙类化合物37个，木脂体类化合物5个，有15个新化合物，均为C21甾体类化合物。

The cytogenetics of interspecific hybrids among the four cultivated cotton species were studied in this paper and results are as follows: The diploid interspecific hybrid (G. arboreum×G. herbacium) F〓 had a four-chromosome-ring at the meiotic metakinesis. The synapses of tetraploid hybrid (G. hirsutum ×G. barbadense) F〓 was found to be regular, which mainly formed bivalents, sometimes some univalents, multivalents and chromosome bridge.

四个栽培棉种间杂交种F〓的细胞学观察结果表明，F〓减数分裂中期Ⅰ，形成一个环状四价体，直接证明了亚洲棉与草棉之间存在一对相互易位；F〓减数分裂中期Ⅰ联会基本正常，主要形成二价体，偶尔出现一些单价体和多价体，以及染色体桥。

Of the 19 cases,19 fetus were found,MRI confirmed 14 cases considered or suspected as fetal corpus callosum agenesis by US(8 cases are completed agenesis of corpus collosom-CACC,6 cases are partial agenesis of corpus collosom-PACC, and 5 cases had took on autopsy),however 3 cases are mild enlargement of lateral cerebral ventricle and 2 cases are leukodystrophy.In these cases,MRI confirmed a Dandy-Walker syndrome and a lipoma of corpus callosum suspected by US,detect a Dandy-Walker syndrome and a microcephalus made missed diagnoses by US.The fetal corpus callosum and additional cerebral anomalies were shown more clearly on MR T_2-weighted images.
