Polymethyl methacrylate is the most used filling materials at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage of bone cement; Bolster for self-replacement can rebound vertebral body height, and balloon kyphoplasty and sky bone expander kyphoplasty can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used in the treatment of percutaneous vertebroplasty.

聚甲基丙烯酸甲酯是目前最常用的填充物；单侧注射和双侧注射疗效没有明显差别；应用对比剂及掌握合适的骨水泥黏稠度可以减少骨水泥的渗漏率；成形前腰部垫枕自身复位可以恢复椎体的高度，避免采用操作复杂及价格昂贵的球囊后凸成形及骨膨胀椎体后凸成形；进行经皮椎体成形时应该配合应用抗骨质疏松药物，以减少椎体再骨折的发生。

The results show that the microstructures of these three kinds of coating are different from those of the matrix (20 steel). The wear resistance of the flame spray coating is 4. 9 times that of the matrix. This is caused by the existance of hard noncrystal microparticals. The wear resistance of the coating by flame spray welding is 6. 3 times that of the matrix. The reason is that the fine crystal grains can be formed and the solution strengthening, dispersion hardening can be induced by these alloy elements. The resistance of the laser remelt coating is 8. 8 times that of the matrix. This is due to the solution strengthening, dispersion hardening and the existence of very hard dendritic crystal, eutectic and martensite in the microstructure.

作者指出，喷涂层由于层内有一定数量高硬度的合金非晶质点存在，其耐磨性是钢基体的4.9倍；喷熔层内合金晶化产生的晶粒细小，合金元素能起固溶强化作用，也能生成化合物产生弥散硬化作用，故此耐磨性是钢基体的6.3倍；激光涂敷层除所含合金元素产生的固溶强化和弥散硬化作用外，表层组织为高硬度的枝晶+共晶和马氏体，故其耐磨性是钢基体的8.8倍。

On the rhombohedron face {1011}, Dauphine twinning showed different shapes of etching pits between individuals, because rhombohedron positive form {1011} and negative form {0111} appeared on both sides of twin partition line, while Brazil twinning showed symmetry plane between the irregular triangle etching pits of individuals. On the trigonal prism section 11(average20, Dauphine twinning showed different shapes of etching pits between individuals, because trigonal prism positive form {1120} and negative form {2110} appeared on both sides of twin partition line, while Brazil twinning should show symmetry plane between the ellipse or quadrilateral etching pits of individuals, which was not observed.

菱面体{1010}面上存在道芬双晶处，道芬双晶双晶缝合线两端分别是菱面体正形、菱面体负形出露处，导致蚀坑形状不同；菱面体{1011}面上存在巴西双晶处，不规则三角形蚀坑形态的方位关系为对称面关系；三方柱切面{1120}面上存在道芬双晶处，道芬双晶双晶缝合线两端分别是三方柱正形、三方柱负形出露处，导致蚀坑形状不同；三方柱切面{1120}面上存在巴西双晶处，椭圆形或四边形蚀坑方位应为对称面关系，但实验中未见到。

In this thesis we introduce this theory into the traffic simulation of cloverleaf and provide a new method in research of the urban traffic simulation. In this system, we use the modeling method of multi-Agent to build the Road Agent, Vehicle Agent, Detector Agent, etc and also provide the intellective decision-making unit and communicate pipe for each Agent.

本文将多智能体技术引入到了立交交通仿真中，采用多智能体的系统建模思路，将车辆、道路、检测器等以智能体的形式建模，并为每个交通元素建立独立的智能决策单元及相互通信的通道，使整个交通仿真系统在各交通智能体的不断交互过程中完成整个仿真系统的运行。

They include the variation of the degradement velocity of different sample, the inhibition product of PCR, the amount of DNA extraction, quality of DNA and the heteroplasmy of some tissue. Correct sequencing, comparison of the result of forward and reverse primers sequencing should be done to rule out wrong signals, and prevent contamination. In addition to gene sequencing, low grade heteroplasmy could be dealt by Denaturing high performance liquid chromatography. Multiplex Ligation-dependent Probe Amplification. The analysis of mitochondrial HV Ⅰ, HV Ⅱ sequencing is able to identify the maternal sanguinity, then it could assist in the human identification. It also complements the genomic STR system in distribution of population, the origin of human, and analysis for fossil.

分析粒线体DNA时必须考虑各类检体腐败DNA降解速度之不同、PCR的抑制物质、DNA的萃取量及品质、特定组织的异质现象、萤光序列分析图及正、反向引子定序结果比对、排除杂讯干扰、防治污染等，除以基因定序外，低程度的异质现象也可用Denaturing high performance liquid chromatography、Multiplex Ligation-dependent Probe Amplification等方法分析，粒线体HV Ⅰ、HV Ⅱ碱基序列的分析可鉴别一个人的母系血缘关系、辅助人类身分鉴定，对於族群分布、人类起源探讨、远古检体的分析可作为辅助STR系统的利器。

To observe effect of receptor ligand on subcelluar distribution of liposome was found that alprenolol liposomes was increased in mitochondria and sarcolemma,especially in nuclei(8 fold increased), as compared with blank liposome.

观察受体配基对脂质体在心肌亚细胞器中分布的影响，结果发现，烯丙洛尔掺入脂质体，使脂质体在细胞核、线粒体和肌膜的分布增加，尤其在细胞核增加最明显，较空白脂质体增多了8倍。

The spores of Cheilolejeunea ventricosa X.L.He were cultured on MS media (without acid and vitamin, pH=6.2, with 1% agar and 1% sucrose). The sporeling development and oil body ontogeny were observed. After a 55-day-long axenic culture, young plants were obtained successfully. Sodium hypochlorite solution was used to sterilize the capsules. Our results revealed that the sterilizing treatment with 0.1% Sodium hypochlorite solution for a period of 5 seconds was optimal. Oil bodies in primary protonemata are nearly homogeneous, but distinctly compound in the leaf cells of the primary leafy shoots.
