At first step, the processor before the deformable body contact the end face of cone die cavity regarded as an extrusion process. The minification of core boss's cross-section regarded as compressibility of direct extrusion, which acted as definition factor when construct the Direct Extrusion Model element. Another step, the model element of flat punch extrusion on wedge piece process was constructed when propose the process of deformable body overflow die corner. In this way the spherical end face of blank looked as cone end face one, t he approximate treatment is one of originality innovation in this paper. At last, the two elements have been connected and constructed the model element of cone boss part's deformation in the open die forging.

对于锥形凸台成形的第一个特征时段，即坯料和锥形凸台型腔的端面接触之前的变形过程，本文将凸台的截面缩小率转换成挤压成形的压缩率并以此为界定，建立了不同截面缩小率时的锥形模正挤压的模型单元；对于锥形凸台成形的第二特征时段即锥形模的角部充满过程，在详细考察锥形型腔端面对变形过程影响的基础上，将变形体的球形端面近似成锥面建立了平冲头挤压楔形体的模型单元；最后将前述两种模型单元有机连结，构建了开式模锻中整个锥形凸台成形过程的定量描述。

In the development history of art of Chinese oil painting, the nonage of twenty century is the unique age, during which Chinese oil painting has began to get up the stage, come to be one of the mainstream of Chinese art.

在中国油画艺术的发展史上，20世纪早期(1900—1937)是一个重要时段，其重要性是在这个时段中国油画开始真正登上历史舞台，成为中国主流艺术之一。

The main diseases studied in 214 clinical studies include: virus hepatitis (65 studies), hemorrhagic fever with renal syndrome (19 studies), typhoid fever (11 studies), bacterial infection (13 studies), bacillary dysentery (5 studies), epidemic encephalitis B (3 studies) and parasitosis (9 studies).

按每5年一个时段统计(1998-2000年3年为一个时段)，RCT所占比例逐渐增加，1983-1987为22.9%(11/48)，1988-1992为29.2%(14/48)，1993-1997占41.9%(26/62)，1998-2000年占28.6%(16/56)。214篇临床研究的主要病种有，病毒性肝炎(65篇)、肾综合征出血热(19篇)、伤寒(11篇)、细菌感染(13篇)、细菌性痢疾(5篇)、流行性乙型脑炎(3篇)、寄生虫病(9篇)。

With the vertical time sequence results computed by the monitoring data (until Aug, 2008) from 28 GPS stations of continuous observation in Tianjin and Beijing Area, the paper analyzes the variation characteristics of vertical component of each GPS continuous stations, calculates the vertical movement velocity of GPS stations in Tianjin and Beijing Area of 2007~2008, compares with the vertical deformation velocity calculated by leveling of 2007-2008 in Capital Circle Area; Furthermore, searches GPS stations nearby the leveling route, corresponding to the first and second leveling time period, calculates the section plane of GPS route, analyzes and compares the section results of GPS and leveling of 2 time periods.

利用北京和天津地区的28个GPS连续观测站资料（资料截至2008年8月）计算得到的垂直向时序结果，分析各个GPS连续观测站垂向分量的变化特征，计算得到2007~2008年北京天津地区GPS站垂直运动速率，并与水准测量计算得到的2007~2008首都圈地区垂直形变速率进行比较；通过寻找水准测量路线附近的GPS站点，相应于水准的初测和复测时段，计算得到GPS路线剖面图，将GPS与水准2个时段的剖面结果进行对比分析。

Most preschools operate from 9.00 till 3.00 five days a weeks and offer sessional attendance, either 2 or 3 days a week or morning and afternoon sessions.

大多数的学前班运作时间为早上9.00直到下午 3.00，每周五天，可以固定出勤时段，如每周2天或者3天，早上或者下午时段。

Undesirable structure and tree species simpleness etc are main problem in existing urban forest, influence urban forest effective exert its zoological function(2) urban forest landscape indexes show: urban forest fragment increased form 1985 to 1995, and decreased form 1995 to 2007, but as a whole, Beijing urban forest fragment is degressive, especially woodland and spinney land.

2在研究时段内北京市城市森林景观指数变化明显，从1985-1995年间破碎化程度增加，而1995-2007年间下降，1985-2007年总体呈下降趋势，其中有林地和灌木林两种主要城市森林用地类型的变化剧烈；城市森林尤其是有林地用地受到人为干扰影响强烈，斑块日益简单化，主要类型城市森林间相互转化现象严重，说明北京市城市森林在研究时段内发生了很大变化。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
