Firstly, This paper processes geometry filtration based on character of orbit's apogee and perigee after orbit model is analyzed and based. Secondly Space Debris is separated into two kinds, coplanar and not coplanar according as location interrelation of target and debris. In Dynamic filtration's processing, considering prediction time limit and orbit perturbation, secular effects which have increaser effect is considered so that some need catching danger time point is appeased, some law about time when target and debris pass intersectant line each other is inferred, when debris and object are in different plane and some similar law also is inferred otherwise. The time list is arithmetical progression. These laws can improve calculation efficiency remarkably; Lastly orbit predict is a course approaching least distance. Danger time point in the last step become beginning time point from which debris and object's position and velocity are calculated by SXP4 Model which is an analytic model.By result, determine that relative movement trend is closer or apart, farther calculate the interval apart from time when predictive least relative distance occurs. Least relative distance and time when least distance occurs is calculated finally. It is a fast approach course adopting varied interval.

本文在分析、建立轨道摄动计算模型的基础上，首先采用基于轨道远、近地点特征对大量编目在册的空间碎片进行初步几何静态筛选，然后根据碎片与目标轨道面的相对位置特点把碎片分为异面与准共面两种情况以进行动态筛选，在筛选过程中考虑到预报时限长度和轨道摄动影响，引入了轨道摄动中具有积累效应的长期项以满足危险时间点的捕捉要求，利用了长期项摄动变化线性的特点导出了碎片与目标异面情况下各自过交线的时间序列成准等差数列的规律性和准共面情况下类似的规律性，从而显著地提高了前期轨道筛选的计算效率；最后对剩余危险碎片和目标飞行器利用SXP4轨道预报模型在前期轨道筛选的基础上以各个危险探测时间点为预报的时间起点，并根据预报计算结果，分析目标和碎片在该时间点的运动趋势是相互远离还是相互接近，推出预计最小相对距离发生时刻相对此刻的时间长度，得到其随时间变化的局部最小相对距离以及危险距离发生的时刻和相对速度，这是一个采用变时间步长、快速逼近最小相对距离的过程。

摘 要：民间体育是指非官方的在民众中开展的体育活动，它不具有世代相传和延续的特点，可以在某一时期出现，又可能在某一时期消失；民俗体育是指那些与民间风俗习惯关系密切，主要存在于民间节庆活动、宗教活动、祭祀活动中，是一种世代传承和延续的体育文化形态，具有集体性、传承性和模式性特点；民族体育有广义和狭义之分，广义民族体育指曾在历史上反映和承载着一个民族共同心理素质、共同文化，为该民族享用的一种特殊文化，中华民族体育、古希腊体育、古埃及体育都是民族体育的具体表现形式，狭义民族体育是指近现代一个民族所独有的，反映并承载该民族共同心理素质、共同文化并为该民族所创造和享用的一种体育文化形态；传统体育是指由历史沿袭下来，是民族在漫长的历史实践活动中积累而成的稳定的体育文化，体现在健身、养生、娱乐思维方式、行为方式等体育文化活动的各个方面，并通过社会心理结构及其它物化媒介(如棋盘、武术器械、文献典籍等)得以世代相传。

Others think the distinction between the two is arbitrary -- macroevolution is cumulative microevolution.

也有人认为二者之间的差别是随意的，即宏观是由微观积累而成。

He structure of people's minds as the "memory trace" has the cognitive ability to guide the behavior of actors, and this structure is constantly in their daily lives without the cumulative said to know how to conduct the practice of awareness.

他把结构看作是人们头脑中的"记忆痕迹"来指导具有认知能力的行动者的行为，而这个结构就是在日常生活中不断积累而成的无需明说就知道如何进行的实践意识。

The death rate grew by 37%. Chinese previously did not need security door. But by now, to some place, security window has been set at seventh floor. For there are too many gangster every where, no company in China would arrange with their workwomen to go home at night. No body knows what really are the food every one have everyday. Neoteny has take place on children. Then we can imagine the situation of our health in the future. There are about 20 million girls in China are pursuing sexual work. That creates 6% of GDP aggregate, which is as much as 1000 billion RMB. This kind of activity had never appeared in the history of human being except Japan. The height of Chinese people is 2.5cm lower than that of Japanese. We can no longer see them by looking down. The small Japan became big Japan. We create 0.1 billions GDP with the payment of 1 person's life, reported by reference news. The number of death in 2003 is 136 thousands. So the number of industrial injury will be 200 thousands. It is true that our GDP is bloody. Actually, this number is a small part of the true number. The numbers which can be accounted are in nationalized business or in a big accident. In personalized business or overseas-funded enterprise, the owner do not pay attention on the death of workers. So the data can not pass to the statistical department. However, the number of death there is much more than that of the first ones. If we add this in account, the number,annually can be compared with the massacre in Nanjing.

中国人从原来不知道防盗门窗为何物，到现在防盗窗已安装到了楼房的七层以上；由于流氓遍地防不胜防，全国企业早已不再安排女工上下夜班；有毒食品已经100%的覆盖了全部行业，每天人们咽进肚子里的食物究竟是什么，只有天知晓；性早熟现象已经蔓延到了学龄前儿童，未来的身体和寿命可想而知；约2000万少女被迫卖淫，创造的收入占GDP总量的6%，相当于一万多亿人民币，这种肉体积累是世界历史上除日本之外绝无仅有的现象；中国人的平均身高比日本人低了2.5公分，由以前低头看日本人到现在抬头看日本人，小日本真的成了"大日本"；《参考消息》报道，中国每亿元GDP工伤死亡1人，2003年死亡达13.6万人，以此推算，今年工伤死亡人数将达到20万，"是名副其实的带血GDP"，其实这个死亡数字不过是冰山一角，能够统计到的死亡数字，要么是国有企业，要么是死人较多的特大事故，私企和外企平常死个把人根本到不了统计部门，而私企和外企用工数量远远超过国有企业，如果考虑到这个因素，每年死亡人数至少相当于一场南京大屠杀。

I ordered a pair of shoes to ship to canada and was told that they would be out that night and in my hands within 5 business days.

为什么从20岁到30岁的时间，才可以跳两级，但是很多人却在30岁到40岁一下子积累身家，成倍数上涨。

PAL was founded in 1978; based on their consolidated experience previously gathered in particleboard plants, the founders focused on the development, construction and sale of machines for the production of particleboards, MDF boards, and later OSB.

The result showed , the two dimensional image accumulated by photon emission at some hours. The spontaneous luminescence could be measured by means of photon counting and imaging acquisition. The luminescence intensity of root and leaf was different at the same plane image. It showed that PIAS could objectively display the spontaneous ultraweak photon, and this results provided experimental basis for resea...

结果表明，自发光子长时间积累可形成二维图象；光子计数和采集图象均可得到植物体的自发发光；通过实验探测到幼苗的根、叶在同一平面图象有不同的发光表现；光子成像系统可客观地比较生物自发超弱发光，为进一步研究超弱发光机理提供实验基础。

Bankers have always earned their crust by committing money for long periods and financing that with short-term deposits and borrowing. Today, that model has warped into self-parody: many of the banks' assets are unsellable even as they have to return to the market each day to ask for lenders to vote on their survival.

银行通常用短期储蓄和借贷来满足资金需求，并通过这种运作形成积累；如今这种模式已经扭曲成了滑稽的自我模仿：很多银行资产都没有销路，正如他们每天都必须回到市场上央求贷款者帮助他们存活下去。

The split between the two groups can hardly be papered over.
