By applying the proposed control law to discrete-time variable structure control systems, the stability of origin and steady of systems are better than the exponential rate reaching law and proportional-constant-variable rate reaching law.

应用该趋近设计变结构控制系统，其原点的稳定性和系统的平稳性都优於指数趋近律和比例－等速－变速趋近律。

The article talks about the main geophysicist associations around the word firstly,then discusses the geophysical methods most in use, its application and the development of the related hardware and software.

文中首先介绍了世界各主要近地表地球物理学家组织，然后简要叙述了近地表地球物理学常用方法和近地表地球物理在环境、工程、考古等各领域的广泛应用以及仪器软、硬件的发展水平。

We establish an asymptotic Lipschitz homotopy invariance theorem for these K-homology groups and K-theory groups. We show that the asymptotic index maps are isomorphisms for the asymptotically scaleable spaces, which include Euclidean cones, simply connected complete Riemannian manifolds with nonpositive curvature.

我们证明了这些K-同调群和K-理论群具有渐近Lipschitz同伦不变性；对于渐近可标度的几何空间（包括欧氏锥、单连通非正曲率完备黎曼流形等），证明了渐近指标映射为同构。

When closely related individuals interbreed,'inbreeding' occurs ,which gives rise to inbreeding depression (which causes a reduction in offspring fitness) and increased genetic homozygosity (which reduces the possibility of evolutionary adaptation to a changing environment, and increases the possibility of extinction).

当亲缘相近的个体进行亲繁殖时，"交近"就出现了。近交引起近交衰退和增加遗传纯合性(它降低了对于环境变化产生进化适应的可能性，而增加了灭绝的可能性)。

The deduced integral invariant is employed to study the 3D predator-prey Lotka-Volterra systems and some new results are obtained.

利用此积分不变量，对三维捕食被捕食 LVS解的渐近性进行讨论，得到了平衡点全局渐近稳定的新条件，推广了已有LVS正平衡点全局渐近稳定的结

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。
