Imaging-based measurements of introversion angle, declination angle, entry point and distance of spinous process at the horizontal plane are important data for percutaneous vertebroplasty. According to pedicle shape features at different stages, included angle, puncture point, path and depth, the vertebroplasty could be performed accurately and safely with reduced damage. Moreover, reliable data are provided for the design of a three-dimensional puncture-oriented device.

提示基于影像学所测量的内倾角、下倾角度、进针点与棘突在水平面上的距离等数据是进行经皮穿刺椎体成形术操作时的重要依据，根据不同阶段椎弓根形态学特点、夹角及确定穿刺点、穿刺路径和穿刺深度可以准确、安全进行操作，减少了损伤，也为设计一种三维立体穿刺导向器提供了可靠数据。

The birefraction filter is also designed to get satisfying output-parameters. At last, the Ti:sapphire laser with flat-flat resonant cavity is pumped with the pumping source at 532nm. The pumping source is got from the frequency doubling of Nd:YAG laser.

In this paper, three kinds of hydroxyl component are prepared for two-component waterborne polyurethane paint, that is, acrylic dispersion, acrylic emulsion and silicone-modified acrylic emulsion. The influence of the composites of these dispersion and emulsions on polymerization process, viscosity, particle size and coagulum are investigated, infrared spectroscopy , inductance coupling plasma , transmission electron microscopy and thermogravimetric analysis are used to characterized their structure, composite, morphology and thermal stability, respectively.

本论文制备了三种用于水性双组分聚氨酯涂料的含羟基组分，即丙烯酸分散体、丙烯酸乳液和有机硅改性丙烯酸乳液，研究了这些分散体和乳液在制备过程中聚合物的羟值、酸值、玻璃化温度、乳化剂、反应温度等对聚合转化率、凝聚物含量、聚合物粘度和粒径的影响，用红外光谱、热重分析、透射电镜和感应偶合等离子技术表征了其结构、组成、形态和热稳定性。

In these three processes, the volatility of the asset price is no more a constant but a deterministic function of time and asset price.

在这三种过程中，资产价格的波动度不再是一个固定的常数，而是时间与资产价格的明确函数。

Regional elections count for little in France and turnout was low. But the 54% share of the vote won by the Socialists was their best result in 30 years.

Its steps include these:(1) purification of WPA;(2) neutralization reaction between purified WPA and sodium carbonate for the salt mixture of disodium hydrogen phosphate and monometallic sodium orthophosphate;(3) adjustment of the mixture's neutralizing degree with additive acid or alkali;(4) quick separation of crystal with additive organic solvent under continue stir;(5) polymerization of crystal under the high temperature for the high quality product of STPP.

其步骤为：(1)湿法磷酸净化；(2)净化后的磷酸与碳酸钠中和反应生成磷酸一氢钠和磷酸二氢钠混合盐溶液；(3)用酸、碱调节确定该混合盐溶液的中和度；(4)加入有机溶剂，通过不断地搅拌使晶体快速析出；(5)晶体经高温聚合，生成高品质的三聚磷酸钠。

It was hypothesized that the 12 subtests of the WISC-R measure three common factors: Verbal Comprehension, Perceptual Organization, and Freedom from Distractibility such that subtests 1,2,4,5 measure VC, subtests 7,8,9,10, 12 measure P0, and subtests 3,6,11 measure FD The chi-square goodness-of-fit test was used to assess the overall fit of this model.

以 LISREL VI电脑程式的「最大概度法」分析的结果，显示「WISC-R 的十二个分量表分别测三个共同因素」、「共同因素之间有相关」、和「唯一性因素互为独立」之因素模式不能解释实际观察资料。

It has important theoretical significance and practical value for promoting level of environmental management and ecotype small town construction.

以海林市2005年实际发展状况为例，通过对比分析指标标准化法、最大隶属度和加权平均三种综合评价的优缺点，筛选与确定加权平均法为最优方法，并验证了本文提出的生态小城镇评价指标体系的可行性。

In chapter 3, on the basis of measure, integration and ergodic theory, it is proved that the statistcal properties and the general complexity of the binary sequences (CG-sequences){b〓} b〓∈{1,-1} generated by a kind of chaos systems and mapping η〓 are as good as white noise sequences. These results lay the foundation of further development.
