As we know, the insymmetry of medical information, the great ethical background and the indefinition of medical expenses, have greatly increase the supervising difficulty of medical insurance. It has been proved that we cannot control the growth of medical expenses simply by the enhancement of the supervision measures of insurance institutions. It is not the optimum choice. Through the analysis to behavior of the insurance institutions, medical agencies and the insurants, this paper has drawn a conclude that the fundamental reason of moral risk is the "third-party payment" social medical insurance system.

为了减少因道德风险而高涨的医疗费用，最安全的措施莫过于同时对医疗机构和被保险人进行监管，由于医疗信息的不对称，医疗消费浓重的伦理性色彩以及医疗消费的不确定性，增加了医保机构监管的难度，实践证明控制道德风险引发的医疗费用上涨，加大保险机构工作人员监管力度，往往不能达到预期的效果，显然不是一个最优的策略选择。

An optimization design scheme is crucial for torpedo, however, there has been no any such method recognized so far. This paper presents a method for torpedo lineshape optimization design based on the iSIGHT. In this method, the optimization strategies of simulated annealing algorithm and continuous quadratic planning method are adopted, and the fluid analysis software Fluent is integrated to calculate the fluid parameters of torpedo body lineshape. The comparison of the optimization results obtained by both the presented and the traditional methods shows that the torpedo lineshape optimization method based on the iSIGHT is satisfactory and feasible.

寻找最优设计方案是鱼雷设计的重中之重，针对目前鱼雷优化设计领域还没有一套公认的优化设计方法这一现状，提出了一套基于iSIGHT的工程设计优化方法，将这款商业软件应用于鱼雷线形优化设计中，采用了模拟退火算法+连续二次规划法的优化策略，集成流体分析软件Fluent对雷体线形的流体参数进行了计算，并与传统优化方法结果相比较，结果表明，基于iSIGHT的优化设计方法在鱼雷线形优化设计中是可行的，能够得到令设计人员满意的鱼雷线形优化方案。

Therefore, in order to guarantee the QoS requirements of each user, we proposed novel power allocation schemes to i minimize the maximum outage probability over all users, and ii to maximize the minimum rate under the outage probability and total power constraints.

由于每个用户的信道状态不同，采用传统的平均功率分配策略并非最优，为了满足用户的QoS要求，首先建立了在总功率受限条件下最小化最大用户中断概率的功率分配方案。

Considering a control problem of failure prone production systems with demand uncertainty, an optimal trinal hedging point control policy was proposed.

But it suffers from the following two shortcomings:(1) the object detected by instantaneous difference is inherently interfered by "virtual shadow" noise;(2) the interior detection of an object might be partly lost whenever the grey scale is quite uniform.

文章提出基于两次差分之间相关性的"复合差分法"，实现了对"虚影"的消除，并提出一种判定最优差分间隔的策略，减少了目标漏检，使目标检测的完整性得到了显著提高。

Further I make use of the conclusion to solve a storage problem, get an optimal control policy between storage and need, and give the corresponding numerical results.And we also discuss the key word that dissolve this kind of problem: the construct and analysis of variational equation.
