The gardener rooster must spend several week constructions exquisitely is similar to complex the artware the nest, moreover must certainly use the blue color the goods to decorate the love nest, if could not find the blue color flower petal, it will bring back to the blue color from several kilometer outside dinner tables the plastic soupspoon.

园丁雄鸟要花费数个星期建造精巧复杂如同艺术品的窝，而且一定要用蓝色的物品来装饰爱巢，如果找不到蓝色花瓣，它会从数公里外的餐桌上带回蓝色的塑料汤匙。

Horizontal windspeed shear,if bigger than a critical value associated with vertical wavenumber m, factor β, hydrostatic stability N^2 and Richardson number Ri ,leads to instability of equatorial ifiternal inertial gravity wave on the y-z plane,which thus causes zonally syrmnetric disturbances to emergence and development.

只要风的水平切变足够大，大于某一临界值（该临界值与垂直波数m，β因子，静力稳定度N^2以及Richardson数Ri有关），在赤道y-z平面上的重力惯性内波也会发生不稳定，从而引起这种沿x轴对称扰动的激发产生与发展。

The paper is organized as follows. In chapter 2, we introduce some concepts about SEA, the abstract SEA model and the convergence definition of algorithm. In chapter 3, we describe firstly the evolution of PMA as an abstract stochastic process, and by characterizing axiomatically the properties of the fundamental selection and evolution operators, we conclude that PMA is essentially a kind of SEA.

本文结构安排如下：第二章介绍了模拟进化算法的一些基本概念、形式化随机过程描述以及收敛性定义；第三章对改进后的 PMA 各操作作了抽象定义，得到了 PMA 的形式化随机过程描述，并公理化地证明了各操作算子为选择或繁殖算子，从而得出 PMA本质上也是一种模拟进化算法；第四章先对选择算子特征数定义作了适当改进，并通过各进化算子的具体特征数指出，如果 PMA 不采取任何执行策略时，算法本身并不收敛。

On the sampling scale of 20 m, the road effects on different dominant populations were demonstrated in their spatial distribution patterns. There were significant increases in the biomass of Schima superba population, the number of individuals and biomass of Litsea rotundifolia population (P.05) along the parallel direction to road, respectively, while those of other populations had no significant difference.

优势物种20 m取样尺度的空间分布格局反映了不同种群对旅游路径干扰的不同响应，其中荷木的生物量、豺皮樟的个体数和生物量在远离旅游路径方向上均呈显著增长趋势，其他物种的个体数和生物量变化不显著。

But because it is a new kind of crime number, different from the preexisting sin, lack of theoretical basis.

但是由于它是一种新的罪数形态，不同于既存的罪数形态，缺乏理论上的依据。

An explicit analytical solution of the threshold pump power of the laser has been derived based on rate equations which contain the attenuation coefficients of the pump and laser radiations as well as the major contribution of the re-emission of the upper level atoms to the pump wave by using the analytical solutions. An analytical solution of the minimum fiber length required for the onset of the oscillation is presented. In addition, the analytical solutions describing the variations of the density of the pump radiation and upper laser level population along the fiber length have also been given.
