The spatial semi-variogram values of above-ground biomass of perennial herbs and Mesophytes, following the increase of spatial distances, showed decreasing trends when semi-variogram values exceeding the effective ranges. Howeve,semi-variogram values of above-ground biomass of other functional groups, following the increase of spatial distances, showed a trend of increasing spatial variability, but semi-variogram values were at unchanged value when exceeding the effective ranges.

多年生草本和中生植物生物量变异函数值，在出现一个相对稳定的基台值后，开始下降，并随着空间距离的增加，空间变异性有减弱的趋势，而其它各功能群生物量表现出随着距离的增大空间变异性增强的趋势，但超过其变程后半方差函数值也基本稳定在一个极限值附近。

Based on Douglas operators, the modified wide beam propagation is presented and the number dissipate is minimized without nearly increasing the memory and computing time. The method is also more stable and accurate than ordinary WBPM. Finally, A novel wide-angle low-loss dielectric slab waveguide Y branch is presented and analyzed by modified WBPM.

In order to survey the numerical diffusion induced by mesh rezoning and variables remap in ALE method,some calculations had been done,and comparisons show that the smoothing does exist,but the numerical dissipation is not serious,it do no harm to physical picture.

为考察ALE方法网格重分、物理量重映导致的数值扩散对计算精度的影响，进行了一些计算比较，结果显示，虽然存在一定程度的抹平现象，但是网格重分带来的数值耗散并不大，对物理图象并没有显著的影响。

On the other hand, a service provider may receive many requests at the same time, and because of the limited resources, it can't serve all of them. Consequently, for both service requesters and providers, there is a challenge of selecting interaction partners. This can be achieved by our proposed one-to-many service negotiation model.

在这个模型中，利用模糊命题表示协商参与者对服务的约束，这些约束是非数值化的；使用效用函数表示对数值化的服务非功能属性的偏好，采用二者相结合的方法建模对服务非功能属性的偏好选择。

In this paper, the study about the interactionbetween the solar wind disturbance and the current sheet is mainly carried out intwo aspects: First, the characteristic propagating of this kind of CMEs erupting inthe open magnetic field between two helmet streamers has been studied by theMHD numerical simulation.

Based on long-term monitoring convergence deformation of Wuqiaoling deep-buried long tunnel, this paper analyzes convergence deformation regularity of two parallel main tunnels. Results show the left main tunnel's convergence obviously exceeds that of the right, because the right main tunnel's construction absorbs the experience of the left main tunnel. Furthermore, authors research on rheology rule of Wuqiaoling tunnel by FLAC(superscript 3D). Numerical analysis result basically is consistent with actual measurement result. Finally, 6 principles to dispose soft wall rock rheology are presented.
