交替运用计算几何中的最远点Voronoi图的性质和统计分析方法中的最小二乘法原理，可使最后参与求解最小外接圆的样本点数减至少量几个，相应算法的运算时间比以往的最优化算法快10倍以上。

So the effect of pollution improvement is affected, at the same time investment benefit is not fully made well. Aiming at the above problems occurred during the improvement of water environment pollution, based on the general analysis of current water environment pollution situation and cause of pollution by the instance of the water environmental pollution improvement in the centre town of Chengdu City, the article puts forward the reasons of water environment pollution of most cities: wastewater collection is insufficient because of delaying of pipe net construction; capability of sewage treatment is inadequate; manage measure is not regular because of management not according to laws and laws not strictly executed; investment channels of pollution implement is unitary.

通过对成都市中心城水环境治理实施方案的研究，对如何与城市建设相结合来进行水环境污染治理提出以下几点看法：①应合理划分流经城市水体的功能区域和正确确定水环境治理目标一些设想；②必须有科学、合理、全面、可操作性强的城市排水规划；③建设、完善污水收集系统，提高污水收集率，加快城市污水处理厂建设，提高污水处理能力；④对中心城河道按防洪、截污、环卫、绿化、景观的要求进行全面整治；⑤治污资金的筹措应从单一的政府投资模式向多元化的融资渠道发展；⑥制定、完善相应的法律、法规、制度以及工程建设管理措施。

In the western mining areas, when from adjustment to restriction adjustment, the original national control points are of low grade, or the points are destroyed and the surface movement is out of shape. thus, there are few control points and the reference frame conversion is a big problem in the western high elevation areas. As a result, this thesis makes a reparable design in accordance with the key problems of holing through survey.

本文就利用GPS技术测设地面近井点的网形布设、观测方法、数据处理作了相应阐述；并对由无约束平差到约束平差时，西部地区可能遇到在矿区分布的原有国家控制点往往只有低等级点，或点位遭破坏、地表移动变形等可能使可用控制点很少的情况、以及西部高海拔地区坐标系统变换问题，提出了针对贯通测量的关键问题应对方案。

In high-voltage var compensation field, when switching the capacitor banks by mechanical switch, it is easy to bound when it closes and to restrike when it opens, and the mechanical switch can not be switched frequently. When switching the capacitor banks by electronic switch in series, it needs dynamic and static voltage sharing circuit and synchronous triggering circuit. It leads to complex structure and high cost.

为解决当前高压无功补偿领域采用常规机械开关投切电容器组开关合闸时触点弹跳产生过电压，分闸时易重燃及不可频繁操作，而采用串联固态电子开关需要相应的动、静态均压及同步触发电路导致系统结构复杂且成本较高的问题，提出一种基于新型高压投切开关的高压动态无功补偿装置。
