Regional development strategy of the state can lead to regional disparities expanding, and also can be as an external condition for underdeveloped region to achieve convergence;resources of western region can cause influence to regional development, but it is limited, and function with other conditions as premise, such as environmental abilities, technologies etc. Even to some degree, western region fell into present environmental poverty just owing to abundant resources.

在外部条件中，国家的区域发展战略可以导致地区差距的扩大，同时也可以作为实现区域趋同的外部条件而存在；而西部地区的资源禀赋对西部地区的发展产生的影响是有限的，并且作用是有条件的，甚至在大程度上正是由于资源的丰富而导致了西部地区目前的环境贫困。

An optimal path planning algorithm of the observer is proposed in this paper, which is based on the dynamic programming. Based on the data measured at the current stage, the optimal moving direction of the observer at the next stage is calculated aiming at the maximum area of the target feasible region convergence.

Moreover, these two systems are linearly independent, they provide the relation of the grounwater levels at any points in the region and at the boundary nods, and also the relation of flowage and the convergence in the region.

这些方程组是由边界单元分析确定的反映区内任一点水位和边界节点水位、流量以及区内源汇关系的方程来构成。

The present study initially put forward that the overestimation to underestimation of actual flow rates by the flow rates calculated using the hemispheric flow convergence method is due to the gradual change of isovelocity surface area in different zones of the flow convergence region, which was proven in our in vitro, animal and human studies.

7血流会聚法对二尖瓣狭窄瓣口面积、室间隔缺损分流量的确定也是一种较为准确、可靠及影响因素较少的方法。(8)本研究首次提出由于不同血流会聚区等速表面形态变化导致半球血流会聚方法计算流量从高估到低估实际流量的论点，并在离体、动物及人体研究证实。

It provides a theoretical basis for reliable and effective operation of the network,which is shown to be globally convergent with respect to its feasible region called quasi-convergence and to be primal in the sense that its trajectories can never escape from the feasible region.

在很一般的条件下证明了网络的总体稳定性问题，这些对于网络的可靠运行与有效运行提供了理论基础。

Results indicate that radial distance of the bushing from the rotor center and the radius of the hemispherical bushing significantly affect wear rate,and minimzing both two values will result in lowest wear for micro-rotor systems in MEMS.However,it is noted that the bearing radius sets a lower limit on the hemispherical bushing radius since the bushings are located beyond the rotor inner radius.It is desirable to reduce their effects on friction and wear on micro-rotors by regulating the radius of the bushing and the radial distance of the bushing from the rotor center within permissive range of micro-fabrication.Severe wear exists with increasing applied load and rotating speed of the rotor.Stress distributions in the contact region are different from Hertz solutions due to the convergence stresses apearing on the uncontinuous curvature line and the contact pressures display symmetrical parabola in the contact region.

结果表明：在MEMS微转子系统中，微转子轴衬偏心距离和转子轴衬半径影响线磨损率，以两者减至最小为较理想，但须注意设计中轴承半径的限制，并使轴衬偏心距离大于轴承内半径；在转子加工制造许可的范围内，可以通过调整转子轴衬的半径和偏心距离来减少摩擦磨损对微电机的影响，随着转子所承受载荷和转子旋转速度的增加，其磨损严重；接触区的应力分布不同于经典Hertz解，这是由于应力集中出现在不连续的曲率线上，且接触区的接触压力呈现轴对称抛物线状分布。
