查询词典 error condition

The error evaluation method most frequently used in current applications is the quadric error metrics, originally proposed by Garland and Heckbert in [9], in which a quadric (represented by a symmetric, positive semi-definite matrix) is associated with each vertex, subsuming the sum of the squared distances of the vertex to all its incident planes.

当前采用的最广泛的误差评估方法是QEM方法。这个方法中，每一个顶点都与一个二次误差相关联，包含了顶点到其相邻面距离的平方和。

Uncertain upper boundary function is learned on-line by using FNN, and proportion controller strengthens the completeness of FNN control strategy. FNN is trained by using disparity target learning error produced by FIE. This can avoid supersaturating problem made by feedback error directly, and restrain influence of measuring noise and improve control performance.

由于模糊技术与神经网络的结合能弥补彼此的不足，因此本文提出了一种模糊神经网络控制器与比例控制器相结合的控制方案，采用模糊神经网络在线学习不确定函数的上界，比例控制器增强模糊神经网络控制策略的完备性。

The target of this thesis is to investigate the relationship between the transmission errors and applied torques of the spur gear by experiments. The main content includes the development of the gear transmission error test facility and its test planning. The transmission error tests and analyses under different loads, center distance and the axial crossed angle on spur gear pairs are also investigated.

本论文的目标系以实验方法探讨正齿轮对之传动误差与其扭力负载之关系，主要内容包含齿轮传动误差之测试设备建构与测试规划、不同扭力负载之正齿轮对的传动误差测试分析、不同中心距之正齿轮对的传动误差测试分析及不同轴交角之正齿轮对的传动误差测试分析。

The results show that at close distances, the field waveform is dependent strongly on azimuth; at distance of several hundreds, the ratio of the peak error values at two azimuths may be bigger than 2; at the distance of 1 km, the mean error is less than 10% with a maximum value of 50%.

结果表明，回击电磁场随方位角的变化非常明显，在距闪电通道几百米距离，误差可达2倍；在1 km处，闪电通道的垂直假定对时域回击辐射场峰值计算的相对误差最大为50%左右，平均小于10%。

At this point, the satellite is in its final configuration and it will reach its final attitude by correcting the azimuth error as well as the elevation error.

在这个时机点，卫星已经进入最后的设定并且会透过修正方位角错误和仰角错误来达到最后的姿态。

The ACS switches from mode 7 to mode 3 when mode 7 is not able to maintain a small elevation error while dealing with the azimuth error at the same time.

当模式7在处理方位角错误时无法同时维持较小的仰角错误时，ACS会从模式7转换成模式3。

Currently, almost all the corrections of radar wave refraction error are based on the assumption that the atmosphere is homogeneous in the horizontal direction, and the azimuth error in the measurement of radar is not corrected.

目前进行的雷达电波折射误差修正，几乎都是建立在假设大气在水平方向均匀的条件下，认为雷达测量的方位角无折射误差，其对于下垫面均匀的平坦地区是可行的，但下垫面复杂地区方位角的折射误差必须修正。

Mode 5 has the higher gains, so it is used only at the end of the acquisition sequence, when the azimuth error can be big, or when the spacecraft has been subjected to disturbances that cause the azimuth error to go over its threshold.

模式5有较高的得益值，所以它只有在当进动序列结束、当方位角错误太大、或是当航空器受到干扰导致方位角错误超过门槛值时才会被使用。

The relative curve between wave speed error and azimuth resolution is given. 8. Based on the scaling azimuth resolution method given by the author, the effect of wave speed error for synthetic aperture processing algorithms based on Stolt migration is given.
