2) the geometrical metrical error
站址测量误差
1.
Based on the method of position location in bistatic sonar,the orientation equation based on the distance and the formula of location error in multistatic sonar were deducted,and the algorithm using distance datas was discussed,and the affected orientation precision of the geometrical metrical error and the temporal metrical error were argued.
在双基地声纳系统的定位方法[1]基础上推导了基于距离信息的多基地声纳系统的定位方程及定位误差的表达式,讨论了多基地声纳系统利用距离信息进行定位的定位原理,讨论了站址测量误差和时间测量误差对系统定位精度的影响,并对不同站址布局下,系统的误差分布特点进行了研究,得出了使定位精度达最高的一种站址布局方案。

测风站
station for air measurement
CefengZhon测风站(station for air measurement)测定风速的专用设施。矿井的总进、回风道,以及各翼、各阶段和各主要作业区的进、回风道,均应设置测风站,并挂记录牌,注明测风站的编号。测风站应符合四点要求:(l)选在巷道的直线段,前后10一15m范围内巷道断面无明显变化。(2)长度不小于4m,其断面积不小于4m2.断面内无障碍物。(3)周壁光滑平整,木支护的巷道需钉以木板,不支护的巷道壁面上应涂抹水泥砂浆。(4)测风站边壁与巷道边壁之间的空隙应严密堵塞,防止漏风。 (染昌才)
