To make a comprehensive view of metapopulation researches, we folly analyze and summarize the present concepts, theories and models of metapopulation in this paper, which primarily includes the dynamical models and simulation approaches of single and competitive metapopulations. Based on the Levin's patch occupant model, the center framework of metapopulation researches, primary principles and mechanisms are discussed. First, Levins rule: the fraction of empty patch will remain constant with habitat destruction as long as metapopulation survives. This rule implies that empty patches have determinant effects on persistence and conservation. Second. Allee effect of metapopulation is incurred by establishing difficulties and dispersal costs, which is important to the studies of reserve area and the minimum available metapopulation size. Third, we analyze the rescue effect that immigrants can reduce the extinction risk of the presented local population. Rescue effect can leads to the improvement of metapopulation sustainability and the decrease of fraction of empty patches. Fourth, the coexistence mechanism of two competing metapopulation is discussed, which suggests that competition-colonization trade off may be prevalent in competing systems. Finally, extinction debt ob tamed from coexistence mechanism is given, which depicts the lost of species richness in the future for the current habitat destruction. After theoretical discussion, we present two popular simulated approaches in metapopulations: probability transition model and stochastic process model.

为了能总观集合种群进展的全局并开展进一步的工作，首先对集合种群的已有概念、理论和模型做了全面的分析和总结；其次对集合种群的发展和概念进行了探讨，以集合种群模型的中心框架：Levins的斑块占据模型为基础，展开对其它原理、效应和机制的探讨；主要包括了Levins原理，即当生境进到破坏时，空斑块比例在集合种群灭绝前保持不变，然后还分析了Allee效应（集合种群的Allee效应主要是由于建群困难和扩散损失造成的）；第三，分析了援救效应：迁人个体可以降低斑块中现有局域种群的灭绝风险，援救效应会增强集合种群的生存力，使空斑块比例下降第四，探讨了两竞争集合种群的共存机制，即竞争－侵占妥协，其共存机制为空间生境中物种共存提供了有力的理论解释。

Ode light is a green, then this bureau has the very high probability to leave the lion or the monkey, this edition named lion monkey version

"Lister made a mental note that this reference to cats and probability could be significant.

&，应译作&Lister在心里暗暗记下，这句提到了猫和可能性的话可能意义重大。

From the former she took some greasy letters, and put in their place the bank-notes, and from the bag took two or three crowns of six livres each, which, in all probability, formed the entire fortune of the miserable couple.

卡康脱女人走到一只碗柜前面，拿出了一只旧皮夹子和一只钱袋，她从那只皮夹里子抽出了几封油腻腻的信，把钞票装了进去，又从那只钱袋里摸出了两三个值六里弗的艾居，这两三个艾居，多半就是这对可怜的夫妇全部的财产了。

"My good friend, as in all probability I own my present safety to that influence, it would ill become me to search too closely into its source; therefore, instead of condemning him for his intimacy with outlaws, you must give me leave to excuse any little irregularity there may be in such a connection; not altogether for preserving my life, for my own idea was that it never was in much danger, but certainly for saving me 4,000 piastres, which, being translated, means neither more nor less than 24,000 livres of our money--a sum at which, most assuredly, I should never have been estimated in France, proving most indisputably," added Albert with a laugh,"that no prophet is honored in his own country."

&我的好朋友，我现在的平安多半得归功于那种力量，这件事我不应该太刨根问底。所以，你不能要求我来责备他和不法之徒之间的这种密切关系，而应该让我原谅他在这种关系上越礼的细节，这倒决非是因为他保全了我的性命，而因为依我看，我的性命是不会有什么危险的，倒是给我省下了四千毕阿士特，四千毕阿特，换成我国的钱，要相当于两万四千里弗。这笔数目，要是我在法国被绑票是肯定不会被估的这么高的，这完全证实了那句俗话，&阿尔贝大笑着说，&没有一个预言家能在他的本国受到尊崇。&

The guyed mast structure is made of soft cables and slender mast shaft, which dynamic characteristics are very complicated due to its large displacement and nonlinearity. Because its complicated theory is not fully understood yet, the damage probability is relatively high under normal design, construction and material.

桅杆结构是由纤绳和杆身所组成，其大变形及几何非线性使得其动力特性十分复杂，在正常设计、建造及材料情况下，桅杆破坏发生的比例之高在土木建筑中是罕见的，这主要是因为桅杆结构复杂的工作机理尚未完全被揭示。

The NWPM uses the Mallows' theory of sample selection probability to design the weight coefficients according to the respective impulse response of FIR filter with the desired spectral response.

基于Mallows样本选择概率理论，由FIR滤波器的脉冲响应来获得伪中值滤波器加权系数，使其具有和FIR滤波器一样的频率选择特性。

The results indicate that it is more accurate to estimate joint frequency by using probability matrixes than frequency matrixes.

结果表明，在计算联合频率中应用风向和风速概率矩阵比应用频率矩阵更准确、可靠。

The bureaucratic organization, to be specifically, has the exactness to deal with the complexity, because it is based on the rational principles, and comes by rational calculation; It has the stability because it is based on the stable rules and hierarchy structure; It has the "reliability" on implementation of administrative goals, because personal factors are removed, the probability of making mistakes is minished under the strict "discipline" and appointment of qualified employees.

具体地说，在应对复杂性上，官僚制组织是按照理性的原则建立起来的，其组织分工和工作程序都是经过理性算计的，更具有&精确性&；以稳定的规章制度和稳固的科层制结构为基础，具有&稳定性&；由于排除管理中的人格因素，严格按照&纪律&来推行工作，就相对减小了工作出错的概率；任用经过培训的合格人员，按照专业分工将复杂的事务分解开来，因而在实现规定的行政目标方面，具有&可靠性&。
