In the presently mobile position technology, GPS's position method is one of the best. This method owns high accuracy less than 15 meters, and can be used with GPS chip in the mobile station. But GPS chip with the high price makes this technology difficult to popular. Therefore, the position technology of GSM communication network is attention to the people gradually. TOA or AOA is more often used among position technology, these methods need only the help of the position measuring instrument to attain time and angle for position calculation. They have good position accuracy, but they are also too expensive to popular. Every positioning technology has its bottleneck such as external environment influence, cost and positing efficiency. Therefore, the purpose of this research lies in finding out the mobile station location and does not emphasize the raise of the accuracy and it only uses existing information to finish position action.

在目前的行动定位技术中，以GPS定位技术为最佳，不仅拥有少於15公尺的高定位精确度，更只需在行动端加装GPS晶片即可使用，可惜高价格的GPS晶片使得此技术难以普及化，因此，以GSM通讯网路为主的定位技术逐渐受人们所重视，其中，又以TOA或AOA等定位技术较常被使用，仅透过位置测量仪器的帮助，便可取得定位所需的时间和角度，并且拥有不错的定位精确度，可惜也受到高价格因素的关系难以普及化，而每种定位技术都有其瓶颈存在，不论是外在环境的影响、成本和定位效能上；所以，本研究的目的在於找出行动端位置，即利用现有的资讯（细胞识别码、讯号强度等）来完成定位动作，而非强调其定位精确度的提高。

摘 要：节点定位是无线传感器网络中的关键技术之一。基于rssi的定位技术是现阶段研究的热点，为解决rssi测量方法定位误差较大的问题，提出一种将rssi测量方法与三角形质心算法相结合的新型定位算法，该算法用三角形质心算法减小rssi的测量误差。仿真表明该算法比基于rssi的三边测量法定位算法的定位精度有较大提高。

The dosage is determined by pH control approach, which does not require a routine jar test. This method can simultaneously determine the optimal pH and economical dosage for oxide-CMP wastewater. The coagulant can be added directly into the raw water without the pH adjusting at first. According to this method, the coagulant acts like a titrant and the pH of the oxide-CMP wastewater is monitored. The optimal dosage is the one that corresponds to a specific pH.

本论文主要以「pH控制法」来决定线上加药剂量值，其与传统瓶杯试验不同的是，其加药逻辑可直接对线上加药进行控制且毋须定期确认参数。pH控制法视混凝剂为酸滴定药剂，直接对进流之氧化层研磨废水进行加药，及至特定pH时，加药停止，此时之加药量即为电性中和去稳之控制点，远较过量加药法经济。

In this thesis, the theories and methods of GA are analyzed in detail , the trend of GA in recent times is briefly discussed.

Phase-lagged cyclic boundary condition is implemented by a novel method in conjunction with the developed sliding interface technique to accurately simulate the arbitrary pitch ratio rotor/stator interaction without any modifications of the physics of the problem. It's for the first time to compose the computational area into one structured grids including both rotor/stator of centrifugal or axial turbomachinery with arbitrary pitch ratio. This method can eliminate the iteration of boundary conditions on the sliding interface and calculate the unsteady flow within rotor and stator simultaneously.
