The single station theodolite was introduced in a measured distance from the aircraft posture information. An exhaustive approach was used to access to the aircraft axis of the feature points and the location in the space was used to obtain space posture parameters. The multi-station theodolite was introduced to get the information of the aircraft flight attitude by method of using planes to the intersection. Two-dimensional image to obtain objective axis by fitting algorithm using Hough transform. And then  Calculate the vertical distance of the origin to the target of the central axis and the origin to the target of the central axis of the angle between the normal and the X-axis obtaining the linear equation in the two-dimensional plane. Two-dimensional axis of the target image and the camera system's optical center only identified a space plane. The aircraft yaw axis angle and pitch angle can be obtained by getting the space axis using plains to the intersection method. Experimental results show that attitude angle error of the single station theodolite is less than 1 when its distance is less than 6000m and attitude angle error of the multi-station theodolite is less than 0.6 when its intersection angle is between 30 and 150. In this paper  according to test result of precision comparing the mathematical model is correct and the algorithm is reasonable in extracting effective parameters of the aircraft's attitude. 2010 IEEE.   Theoretical analysis of the effects of operational and designed parameters on the performance of a flow-through porous electrode 期刊论文  OAI收割 journal of electroanalytical chemistry, 2009, 卷号: 625, 期号: 2, 页码: 165-171 作者:  You, Dongjiang;  Zhang, Huamin;  Chen, Jian 收藏  |  浏览/下载：25/0  |  提交时间：2010/11/30 Flow-through porous electrode  Two-dimensional mathematical model  Dimensionless parameters  Mass transport  Ohmic resistance  Kinetics   Two-Dimensional Mathematical Model and Numerical Simulation Describing the Melting Process of Cylindrical Basalt Bed 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 1999, 卷号: 8, 期号: 4, 页码: 262,269 Yan Quanying; Shang Deku; Tan Heping; Zhao Yuzeng 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/12 two-dimensional mathematical model  numerical simulation  basalt bed  melting process.
