The problem of multi-objective usually meet many conflict each other and can not use the objective of the same standard unit, then to employ membership function of fuzzy theory,at first each objective function to change fuzzy set and express with membership function, membership function include the maximum constraint, minimum constraint, the decrease function of monotonic property, to become optimal of the multi-objective function, but still to scanty of weighting value with regard to adjustment of objective function, thus this thesis proposes the method of combine orthogonal arrays and particle swarm optimization to solve the problem of multi-objective optimal power flow, each objective function separately add weighting value, to setting each weighting value of objective function in order to the result of anticipating.

多目标最佳化的问题通常会面临到许多互相冲突且不能用同ㄧ标准单位的目标，於是利用模糊理论中的归属函数，首先将各目标函数转换成模糊集合并以归属函数表示，归属函数包含了最大限制值、最小限制值、单调的递减函数所组成，将各目标函数利用归属函数表示，形成单一目标函数的最佳化，但是仍缺乏权重值对於目标函数的调整，於是本篇论文提出ㄧ种权重值设定与粒子群优演算法的方法去解决多目标最佳电力潮流的问题，将各目标函上分别加上权重值设定各目标函数的权重值，得到预期的效果。

NET基因多态性G1287A与社会心理学因素交互作用与MD的关联研究：G1287A AA基因型与精神质人格、内向型人格及较少采取积极应对方式可能存在超相乘模型交互作用，γ分别为2.528，1.878，1.935；与神经质人格可能存在正相加模型交互作用，γ为1.032；与生活事件可能存在夫相加模型交互作用，γ为0.791；与消极应对方式、社会支持可能不存在交互作用。

The result shows:(1) the value of R in situ is higher than 0.8, which is lower than that in lab;(2) the averaged value of relative error in spring tide is higher than that of in neap tide and the value is less than 15%.(3) the particle size is the main factor that influences the precision of OBS, while the biology, the color of particle and water, the air bubble in water have some effect on it.

主要结果有：(1)现场OBS标定R值比室内标定偏低，但也在0.8以上；(2)大潮平均相对误差值变化比小潮大，在悬沙浓度低于1.5kg/立方公尺条件下，大小潮悬沙浓度平均相对误差都在15%以下；(3)悬沙粒径大小是影响OBS观测精度的主要因素，生物、泥沙颜色、水色和水中气泡等因素也对观测结果产生一定影响。

According to their theory, they thought the value judgment including ethics and moral is meaningless statement, this result leads to a possible situation: If value judgment is unverifiable, certainly, people will doubt on both meaning and effectiveness of the judgment; if value judgment is unverifiable, the guide for people will also be meaningless, and rational intellect have to give way to the ambient pressure as well as the nescient preference.

这种关于价值判断是不可证实的论证将导致的可能后果是严重的：如果价值判断是不可证实的话，那么人们必然会对价值判断的意义和有效性产生彻底的质疑；如果价值判断是不可证实性的话，那么哲学对人类生活的指导将会显得十分无力，理性的智慧将不得不让度给无知、外在的压力和盲目的偏好。

Our analysis framework relies on the reflected Backward Stochastic Differential equation approach.We characterize the value functions of the noncallable bonds in terms of the reflected Backward Stochastic Differential equation,Then the relationship between the value function of convertible bonds and reflected backward stochastic differential equations with single reflect is built at the same time,and provide the optimal conversion strategy for bondholders.2:We get the value of non-callable convertible bonds by numerical methods.
