Then it puts forward sub-regional-economic cooperation as the best choice for Yunnan and its neighboring countries to have economic and trade cooperation. In the practical study of developing Yunnan"s frontier trade, this essay analyzes to the full the current situation and existing problems of developing Yunnan frontier trade, combining with China"s accession to WTO, exploration of the west regions and the founding of the ASEAN. Frontier trade plays an important role in the nation"s and Yunnan province"s social economic life. It has great influence on the nation"s safety. Frontier trade is centered on the low-cost consumable supplies and consignation trade. Its prosperity for a long time relies on the inland, which constitutes three remarkable characteristics of Yunnan"s frontier trade.

在开展云南省边境贸易的实践研究中，本文从六个方面较为全面地分析了云南省边境贸易发展的现状、存在的问题，指出：边境贸易在全国和全省社会经济生活中占有重要地位，对国家安全影响深远；边境贸易以低附加值商品和易货贸易为主；边境贸易市场的繁荣长期依赖内地，是云南省边境贸易最显著的三个特点，结合中国加入WTO、西部大开发、大东盟的成立等，对云南边境贸易在新时期的发展方向作了一些初浅的探讨。

Properties of efficient portfolios and the efficient frontier to the model are systematically analyzed. Our main results concerning the properties are: every efficient portfolio can be solved by minimizing portfolio risk under a given level of portfolio return or by maximizing portfolio return under a given level of portfolio risk; on the efficient frontier, the risk is a convex and strictly increasing function of the return and the return is a concave and strictly increasing function of the risk; the utility function on the efficient frontier can be expressed as a quasi-concave function of the risk or the return if the investor's utility function is quasi-concave.

从理论上系统地对该模型下的有效投资组合和有效前沿的性质进行了分析，结果表明：每一个有效投资组合可通过在给定期望收益水平的条件下最小化投资组合风险来获得，或者在给定风险水平的条件下最大化期望投资组合收益来获得；在有效前沿上，风险是收益的严格单调递增凸函数，收益是风险的严格单调递增凹函数；当投资者的效用函数是拟凹函数时，则有效前沿上的效用可表达成风险或收益的拟凹函数。

Location of the inland frontier regions have greater uncertainty and imperfectibility at politics and economy than other regions,therefore the border " shielding effect " makes the actual advantage of location of the inland frontier regions uncertain,especially the relative advantage may change in the future,cause the transaction costs of the inland frontier regions to be redounded .

After the winding up of the 10-year long first-phase of the nation-wide land frontier defense infrastructure construction, the overall capability of patrolling roads and frontier wire entanglement have been extended to 20,000 kilometers, and the fast response and emergency handling capabilities of the frontier defense troops have been improved greatly.

历时10年的第一步大规模陆地边防基础设施建设完成后，边防巡逻路、边境铁丝网等基础设施建设达到2万公里，边防部队快速反应和处置突发事件能力明显提高。

Location of the inland frontier regions have greater uncertainty and imperfectibility at politics and economy than other regions,therefore the border " shielding effect " makes the actual advantage of location of the inland frontier regions uncertain,especially the relative advantage may change in the future,cause the transaction costs of the inland frontier regions to be redounded .

内陆边境地区在政治和经济上存在较大的不确定性以及信息上的不对称性和不完善性，由此产生的边界&屏蔽效应&使得内陆边境地区的区位实际优势不确定、特别是相对优势在未来可能发生变化，导致内陆边境地区的交易成本被抬高。

The existing points and lines would form a closed geometric shape. If we put the new point Z outside the closed geometric shape at first and later then found that the point Z has neighboring relationship with the existing point A which is inside the closed geometric shape, we could not link point Z and A directly because that would bring line crossing. If we rearrange the point Z into the closed geometric shape, that also would cause a lot of work to do. With the help of Exclave, all problems could be solved easily. We use point X outside the closed geometric shape as the Exclave of the point A. Then the line between point Z and X could demonstrate the neighboring relationship of the point Z and A.

原有的各点和相邻线段往往会形成一个封闭的几何图形，如果我们把新增点 Z 设在原有的封闭几何图形外部，后来又发现该点 Z 和位于封闭几何图形内部的点 A 存在相邻关系，这时不能直接将两点连接因为那将产生交叉，而如果将点 Z 重新设在封闭图形内部也将导致大量的调整工作；此时借助外飞地的概念，可以轻松地解决上述问题，即在封闭几何图形外部设置点 X 作为点 A 的外飞地，两点使用同样的颜色，用点 Z 和点 X 的相邻线段表示点 Z 和点 A 之间的相邻关系。

According to the principle of the diameter of a circle corresponding to the right angle and the principle of short side for little angle in right triangle, projecting the initially-chosen point to the hyper-planes of the linear equation group in which every linear equation can be regarded as a hyper-plane and the projection points can be obtained. The initially-chosen point, and one arbitrary projection point, and the solution point are all on the surface of the relative hyper-geometry ball, therein-to, there is a projection point which is nearest to the solution point and it can be regarded as the next iterative initially-chosen point, so the solution problem of the linear equation group can be changed as an iterative problem of approaching the solution on the surface of a hyper-geometry ball.

根据直径对应的圆周角足直角以及直角三角形中短边对小角的原理进一步知道，当将初始点向线性方程组中各个方程所代表的超平面上投影得到投影点时，初始点和其任何一个投影点及方程组的解点都将位于一个相应的超球面上，其中必定存在一个投影点离问题解点的距离最短，即把该点作为下一次迭代的初始点，从而可将线性方程组求解的问题变成球面上逼近解点的迭代问题。
