Effect of active filler on joining property of silicon carbide to itself by polysilazane;2. The design,cross-linking and pyrolysis of preceramic polymers as well as addition of active filler ,all of which influence the ceramic yield,were analyzed.

针对先驱体转化法陶瓷产率低的问题，从陶瓷先驱体的设计、先驱体的交联工艺、裂解工艺以及活性填料的添加等方面分析了影响陶瓷产率的各种因素，总结出提高陶瓷产率的措施，最后提出今后进一步研究的方向。

Two polysiloxanes (SR2 and P67) and one polycarbosilane were chosen as preceramic polymers. TG-DTA-MS, FT-IR, XRD,〓Si MAS-NMR, SEM, TEM, SAD, HREM, chemical analysis and density measurement techniques were used to study the cross-linking and pyrolysis mechanisms of the preceramic polymers. The development of chemical composition and structure, density, phase composition and microstructure of the solid pyrolyzed products during pyrolysis process were systematically investigated. While pyrolysis temperature approached 1000℃, ceramization process of the preceramic polymers almost completed, and ceramic yield of the preceramic polymers hardly changed any more.

选取了两种聚硅氧烷（SR2和P67）和一种聚碳硅烷作为聚合物先驱体，利用TG-DTA-MS、FT-IR、XRD、〓SiMAS-NMR、SEM、TEM、SAD、HREM以及化学成分分析、密度测量等手段，研究了聚合物先驱体的固化机理；以N〓为热解气氛，系统地考察了各种聚合物先驱体在热解过程中，其热解产物的化学成分和结构、密度、相组成及显微结构的演变规律。

The gross and microscopic structures of the discs reflect how these fibres fulfill their two main fuctions, which are to allow and restrain movements at the interbody joints, and to act as the prime component in the transmission of loads from one vertebral body to the next.

椎间盘大致与细部的结构反应这些纤维达到两个主要机能的方式，这两个机能是允许并限制介体关节的活动并扮演从一个椎骨体到下一个椎骨体负荷传达的主要成分。

According to the root type division the Chinese Dwarf cherry belongs to the inductive type of root primitive body,From above several aspects we can see that the mechanism of soft-wood cutting is : Under the condition of without root primordium ,the root primordium appear from cambium by using rooting accelerator under the condition of well temperature ,humidity ,and light, then the root primordium breaks through the cerebral cortex, finally extends to outside .

从以上几个方面我们可以看出，欧李嫩枝扦插生根繁殖的机理为：欧李嫩枝在无根原体存在的情况下，经过生根剂的处理在合理的温度、湿度及光照条件下，由其形成层部位产生根原体，随后根原体突破皮层，伸向外部。

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 tail iv injection, the blood exposure time of stealth liposomes and the area under blood drug concentration-time curve were pronouncedly increased, compared with the regular liposomes group and the free doxorubicin group,respectively.

以化学梯度法包封脂质体，用两亲性聚乙二醇-二硬脂酰磷脂酰乙醇胺对脂质体膜进行修饰以制备隐形脂质体；用HPLC-UV法测定给药后小鼠体内组织中的药物浓度。

And the stress condition has been shown to have a great effect on the behavior and life of a hip prosthesis.

股骨假体的受力情况是假体设计过程中首先要考虑到的，它影响着假体的行为和使用寿命。

Bone resorption around AML prothesis developed slowly after 10 years and did not affect the stability in the long term.

在术后12年内ABG假体周围骨丢失少于AML，在10年后AML假体周围骨丢失发展缓慢，未影响假体的长期稳定。
