针对花键的齿形误差和齿向误差，按照误差计算原理，得出了计算结果及其随安装角改变的变化规律。

It is indicated that the accuracy of the measured value is determined rather by the practical relative error than by the maximum relative error. It is correct that the nearer the scale reading approaches the maximum, the more accurate the measurement is. The scale reading need not be required above 2/3X.

指出使用电表进行测量时，测量值的准确性是由其实际相对误差而非最大相对误差决定的；并非电表的读数越接近满刻度，测量值的准确性就越高；使用电表进行测量时，电表的读数不必被限定在2/3X上。

So the accuracy of DEM is mainly determined by error of data collection and error of elevation interpolating.

因此DEM的精度主要由数据采集和高程插值所决定。

Swindle, said Eastern Shopping and Yahoo Auctions Payment Error Information to the public, claiming a refund of the original contractors mistakenly set the previous trading installment deductions or victim error, mistake a refund will set phases such as the right to charge damaged, it tells the people to the ATM was required to operate changes, lifting hire charge; as soon as the public deceived again after the "Financial Supervisory Commission," said the account has been criminal to use the name of money laundering, must sink "financial security account" to avoid being the freezing of accounts, lured victims of the deposit removed, changed into the aforementioned fraud of financial security accounts.

1-2 Online Shopping Fraud 假借东森购物免付费显示电话、雅虎奇摩购物等方式通知民众，称原承办人误将退款设为分期扣款或被害人先前交易错误，误将退款设为分期扣款等将使权利受损，即向民众要求需至提款机操作变更，解除分期付款扣款；俟民众受骗上当后，再以「金融监督管理委员会」名义表示帐户已遭歹徒利用洗钱，需汇「金融安全帐户」，以免遭冻结帐户，诱骗被害人将存款解除，改存入前述诈骗之「金融安全帐户」。

In this paper the accuracy of the precision engineering control networks (Trilateration and Triangulation), established by using modern electronic distance measuring instruments and theodolites is discussed, and the method of optimization design is proposed that is based on the theory of probability and error propagation and applying the error ellipses to analyze the position accuracy of the points.

node location is one of the key technologies in wireless sensor network.rssi－based location is a hotspot in nowadays.for resolving biggish error in rssi－based location,the paper presents a new method of location,rssi－based triangle and centroid location,using triangle and centroid method to reduce the error of rssi measurement.simulation experiments prove that this algorithm can obviously improve the location accuracy compared to trilateration.

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。
