Strabismus diorthosis under microscope has clear advantages compared with traditional strabismus diorthosis. The muscle, blood tube and the move of needle in sclera as well as the depth can be seen clearly during the operation which make the operation easy to control, so we can properly and correctly perform the operation, shorten the operation time and avoid complications like blooding, penetrate sclera which often occur during the traditional operation. The strabismus diorthosis under microscope using general micro equipments can also separate structure correctly with fewer operation steps, light reaction after operation, sooner recovery after operation, which is suit to patient who needs strabismus diorthosis.

显微镜下斜视矫正术较传统直视下斜视矫正术具有较明显优势，可以清晰地看清肌肉、血管、及针在巩膜内的走行、深浅，使手术较易掌控，可以使手术量及手术操作准确无误，缩短手术时间、避免出血、穿透巩膜等直视下手术常见的并发症的发生，同时组织分离准确，操作减少，也直接减轻了术后反应，缩短了术后恢复时间，适合所有需斜视手术患者，优势为初学者易掌握巩膜进针深度。

Centrifugal energy saving analysis and measures: 1 improve the efficiency of centrifugal pumps a first step, in the selection of comparison, when many suppliers Selection program, in considering the cost-effective choice as far as possible under the premise of efficient programs; the second step , accredited professionals must Mill producers, affecting the pump efficiency of the key components such as impellers, pump body, pump cover, diversion devices, such as the manufacture of quality producers, especially for the airfoil impeller , outlet angle, leaves the sub-degrees, the shape of flow channel, to control the quality of finish, etc., so that products are delivered in the current production under the conditions of highly efficient products; the third step, the scene in the production of installation and debugging process, pump to ensure a solid foundation, with the driving machine for good, before and after valve flexible piping layout design is reasonable, on-site control is feasible and safe, the complete and accurate monitoring instrumentation to ensure that pump operation can carry out real-time monitoring; fourth step , are at long-term operation of water pumps necessary to pay attention to the equipment inspection and found anomalies reflect real-time reporting, in the normal minor repairs, overhaul cycle, to deal with the replacement of wearing parts inspection to ensure the pump's long-term safe and efficient operation.

第一步，在选型时多比较各供应商的选型方案，在考虑性价比的前提下尽量选用效率高的方案；第二步，派驻一定的专业人员驻厂监制，对影响水泵效率的关键零部件如叶轮、泵体、泵盖、导流器等的制造质量进行监制，尤其对叶轮的翼形、出水角、叶片的分度、流道的形状、光洁度等质量进行控制，使交付的产品是在当前的生产条件下的高效率的产品；第三步，在生产现场的安装调试过程中，要保证泵的基础牢靠，与驱动机对中良好，前后阀门开关灵活，管道布置设计合理，现场控制安全可行，各运行监控仪表齐全准确，保证泵的运行过程能够进行实时监控；第四步，是在水泵的长期运行中要注意对设备的点检，发现异常情况即时反映汇报，在正常的小修、大修周期中，应对各易损件进行检查更换，保证泵的长期高效安全的运行。

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。
