In the new method for two-dimensional problems the line integrals onboundary elements are converted into the evaluation of potentialfunctions at the ends of these elements.For three-dimensional cases,thesurface integrals on the usual boundary elements are transformed,through an application of Stokes'theorem,into line integrals on thebounding contours of these elements.

边界轮廓法是刚刚出现的一种新型的边界元法，该方法的核心是利用边界积分方程被积函数散度为零的特性，对二维问题，原积分方程中沿边界单元的线积分被化为单元两端点势函数之差计算，对三维问题，将边界单元上的面积分转变为沿单元轮廓的线积分，它是一种十分简便有效的边界元新技术。

Evaluation each period of green food business enterprise piece, habitat monitor area, real object total amount and sale sum Be importation index sign; Again selection each year green food export sum is output index sign, to 1999-2006 year China green food development level of time sequence data calculation result enunciation: Green the food export's ability exaltation trend, which is a DEA for 2004-2006 years valid of age, but further analysis after detection: Green food yield 2002-2006 year average growth 29.2%, but export rate didn't°yet break 13%, and every year export rate growth not arrive a percentage point, and the demand of international market at continuously extension, particularly west nation green food consume growth the rate is in above 20%, this has already result in produce and foreign trade mutually separate, can't orientation open of market economy of request, this elucidation our country green food export development medium of strategy existence very great problem, For further expanding the international market, the analysis of market-orientation should be strengthened, the product quality and enterprise credit should be improved and the proper strategy and way to access market should be taken in order to break through the green barrier and keep up the competition ability which can be continuously developed.

评价将各期的绿色食品企业个数，产地监测面积，实物总量和销售额作为输入指标；再选取各年绿色食品出口额为输出指标，对1999——2006年中国绿色食品发展水平的时间序列数据计算结果表明：绿色食品出口能力呈现逐年提高趋势，2004——2006年是DEA有效的年份，但进一步分析之后发现：绿色食品产量2002—2006年平均增长29.2%，而出口率还没有突破13%，而且每年出口率增长不到1个百分点，且国际市场的需求量在不断扩大，尤其西方国家绿色食品消费增长率在20%以上，这已造成生产与对外贸易相分离，不能适应开放的市场经济的要求，这说明我国绿色食品出口发展中的战略存在很大问题，需要进一步开拓国际市场，加强市场定位分析，提高产品质量和企业信誉，并选择适宜的进入战略及方式，以利于冲破绿色壁垒和保持持续发展的竞争能力。

The primary views as following: water rights allocation means to distribute the natural resource water's usufructs, real right of product water and water-abstract rights in different areas and among various subjects by government or market, which is an important method to use water efficiently and to better resources structure; water rights allocation should emphasize the value of efficiency and equity; water rights administrative allocation should follow nine principles such as the principle of the priority to residents' daily water and take into consideration the domestic water and the environment water, the principles of sustainable development, of united planning and macro-adjustment, total quantity control and ration management, plan the distribution of water by unit of drainage area, respecting the conventional water rights, earlier applicants first in the same sort of rights, combination of administrative allotment and transference with compensation, the water rights gained by transferring is terminable; water rights allocation inside the government departments should distribute according to population, area, and output via planning and negotiation means; water rights allocation outside the government departments should decide the use order according to the kind of water, which can be realized by competition or non-competition methods.

主要观点是：水权配置是运用行政或市场手段对自然资源水的使用权、产品水物权和取水权在不同区域之间或不同用水主体之间的分配，是有效利用水资源、实现资源优化组合的重要手段；水权配置应当兼顾效益和公平两大价值目标；水权行政配置应当遵循居民生活用水优先并兼顾生活和生态环境用水、促进人类可持续发展、统一规划宏观调配、总量控制定额管理以供定需、以流域为单元制定分水方案、尊重习惯水权、同类水权申请在先、无偿划拨与有偿出让相结合、出让方式获得水权有期限等九大原则；水权行政内部配置应当以人口、面积、产值等为依据通过计划和协商等方式进行配置；水权行政外部配置应当按照用水类别确定不同的用水顺序，并通过竞争性和非竞争性手段实现。

Analysis results on townships and villages general statuses showed township health center and village clinic are the major health care facilities in rural poor areas. The number of staff in 36 THCs and 104 VCs were a little lower than the national average. In township health centers, 59. 9% staff are with primary or without any professional titles and 35. 9% of the total staff have no professional degrees. The average gross value of fixed assets per THC is 186000 yuan, among which special equipment values 41000 yuan. Among professional buildings 43. 3% of total area were dangerous. Only one THC can provide emergent service. 47. 2% THCs be able to diagnose and deal with common emergent stomachache. The provision of health services was lower than average level of national rural areas. Frontier Model analysis showed regression coefficients of total outpatient emergency service, total inpatients, average personnel income, number of total staff, number of doctors and technical index were all larger and positive. It meant that these variables would contribute more to the cost-frontier, and their increase would cause the total health cost rising. So increasing health service provision, improving service quality and functions of health facilities may be the best ways to increase efficiency of these facilities. Also the model showed THC inefficiency eu was 1. 68, which means 40% of the cost wasted. Apart from internal and external factors, residents'health care utilization deficiency and inequity is one of major factors causing inefficiency eu.

乡、村基本情况结果表明，农村贫困地区乡卫生院和村卫生室是农民就近就医的主要场所；36所乡卫生院以及104所村卫生室的人员数量，略低于全国同期农村平均水平；在乡卫生院中，初级职称和无职称者的比例占59.9％，无专业学历者占35.9％；平均每院固定资产总值18.6万元，其中专用设备4.1万元，业务用房中危房面积占43.3％；36所卫生院中，具备急救条件的只有1所，能诊断和处理常见急腹症的占47.2％；卫生服务提供量均低于全国农村平均水平；Frontier模型方法显示，总门诊人次、总出院人次、平均人员工资、人员总数、医生数和技术指数等指标的回归系数较大，且均为正数，即这些变量对"前沿"成本的贡献较大，其正向变化均会带来卫生服务总成本的增加，表明增加卫生服务提供量，提高质量以及完善机构服务功能，是提高乡卫生机构效率的有效途径；同时Frontier模型结果显示，卫生院的低效率〓为1.68，经换算即40％的成本处于浪费状态；影响乡卫生院低效率〓的因素有外部和内部的，而需方卫生服务不公平及利用不足是其主要因素之一。
