About 30～35 min after insemination the first polar body was ejected and the second polar body was ejected about 10 min later.

授精后约30～35 min放出第一极体，第一极体排出后约10 min第二极体排出。

In some cases, the height of vertebra could be increased after the operation, however, it is not for the technology but for the posture of patients that the patients would pronate on the table and over-straight their bodies. In this situation, bone cement can be injected into the vertebras and enhance the int ensity, change the spine kyphosis, recover the spine physiological line, so it gets to the aim of treatment.

有时病椎术后高度增加，不是椎体成形术操作本身抬高椎体高度，而是在病人俯卧位时进行的体位引起过伸而复位，此时椎体内再加入骨水泥固化，使椎体固定在复位后的位置上，并且增加了耐压强度，同时改变了脊柱的后凸畸形，恢复了脊柱生理力线，这样就会达到治疗目的。

After collecting the bacterial cells and breaking the cell by means of ultrasonic, the inclusion bodieswere extracted. The extracted products were denatured with 8 mol/L urea and purified through Ni-NTAcolumn. The purified products were renatured by dialyzation, and then were analyzed by SDS-PAGE.

在优化条件下诱导重组菌表达，收集菌体经超声波破碎和裂解后提取不溶性包涵体，以8mol／L尿素处理包涵体提取物并进行Ni-NTA亲和层析纯化，纯化表达产物经透析复性后以SDS-PAGE分析其复性效果。

60Co-γray was a useful mutagen in induced mutation breeding .After treated with 60Co-γray ,free-living conchocelis of wild Porphyra haitanensis were induced and represented in offsprings. Purple mutant and excellent practical characters strains were selected from a lot of gametophytic blades. Single cell clone and enzymolysis were used to propagate fast in pure strains of induced mutations.

坛紫菜野生丝状体经一定剂量60Co-γ射线辐照后，子代叶状体发生了变异，经大量培养后筛选出紫色突变体（3号Ⅰ）和经济性状优良的个体（7号Ⅰ和7号Ⅱ），通过体细胞酶解和单克隆技术快速获得诱变选育纯系，并对其主要经济性状进行了研究。

Improements in ertebral height and kyphotic angle were consistently reported with balloon kyphoplasty and in a small number of ertebroplasty case series.

球囊扩张椎体后凸成形术的研究和一个小样本的椎体成形术的病例研究都报道了对于椎体高度和后凸角的改善。

At 7 days following conventional culture, neurons were ellipse and subtriangular, with big body and clear boundary and many processes. Following retinoic acid culture, the number of neurons was increased, with clear morphology and a few processes.

常规贴壁分化培养7 d后，神经元多呈椭圆型和近似三角形，胞体大，细胞边缘清楚，胞体上有多个突起；而维甲酸诱导分化培养后，神经元数量增加，形态清楚，但细胞胞体上突起较少。

By means of microscopic observation, we found the body wall ofchemical-stressed SCN shrinked, and stylets of some stressed SCN breaked through the body obviously. Trehalose content and trehalase activity of stressed and unstressed SCN wereassayed by enzyme-labeled instrument.

利用显微镜对虫体进行观察发现，SCN受到化学胁迫后，体壁发生不同程度的缢缩现象，有的胁迫处理后虫体头部口针明显突出体外。

Using indirect ELISA, the contents of vitellin in the fat body, haemolymph and ovary of P. japonica were detected. The results suggested that the vitellogenin was synthesized in fat body at the 2nd day after eclosion. The contents of vitellogenin in fat body, haemolymph and ovary increased quickly on the 4th day after eclosion and reached the peak stage approximately on the 8th day in adult stage.

采用间接竞争ELISA法，系统测定了龟纹瓢虫成虫期脂肪体、血淋巴和卵巢中卵黄蛋白的动态变化，结果表明：脂肪体是卵黄原蛋白合成的场所，卵黄原蛋白的合成始于羽化后第2天；脂肪体、血淋巴和卵巢中卵黄原蛋白的滴度在羽化后第4天开始迅速上升，至成虫期的第8天左右达到高峰期。

RPC steel and RQ steel are constituted by bainite and martensite microstructures before tempering. The microstructure of RPC steel did not change obviously except some bainitic laths coalescing were detected by means of SEM during tempering, while the boundary of bainitic laths of RQ steel disappeared quickly and finally formed polygonal ferrite forms accompanied a dramatic decrease in hardness.

回火前两种钢板组织均为贝氏体和马氏体的复合组织，经RPC处理后的钢板随回火温度的提高组织没有明显变化，只是一些板条出现合并现象，而经过RQ处理后的钢板随回火温度的升高板条很快消失最终演变成多边形铁素体，硬度也随之大幅度下降。

A new version of Vertebroplasty, Kyphoplasty actually realigns the kyphosis of fractured vertebra before injecting the bone filler.

新版本的椎体成形术，椎体后凸成形术，其实realigns后凸畸形椎体骨折前，注入骨填料。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
