模型误差 meaning in English
model error
Examples
- The results of spatial analysis and planar analysis were finely compared with the measured value . by comparison , some conclusions are obtained : model ' s errors are in evidence , when using planar model to analyze the cable - stayed bridge in building , especially for girder ' s distortion ; the transverse distributing of direct stress along axis of bridge is apparent ; and the method of planar analysis ca n ' t satisfactorily solve asymmetry of stress ' s transverse distributing
空间分析结果、平面分析结果与实测结果这三者的比较表明：在pc斜拉桥施工控制中，用平面杆系理论进行结构分析存在一定的模型误差，尤其在主梁的变形分析上；纵桥向正应力沿横向分布的不均匀性明显，用平面杆系理论没法很好地考虑此效应。 - Kalman filtering is widely used for data processing in kinematic gps positioning , while the practical application of kalman filtering requires the dynamic model ( functional model ) and the stochastic model to be reliable and accurate , yet it is difficult to maintain regular motion of the object in actual kinematic positioning , thus model biases are usually generated
摘要动态定位的数据处理中广泛应用卡尔曼滤波，而卡尔曼滤波的应用要求动态模型（函数模型）和随机模型可靠和切合实际，但实际测量定位中难以保证观测对象的规则运动，因而容易出现模型误差。 - ( 3 ) how to design the bayesian test method about the parameter ' s linear hypothesis according to the relationship between the multivariate t distribution and f distribution . ( 4 ) the bayesian diagnosis and unit root test method about the random error series . ( 5 ) the bayesian mean value quality control chart when the variance is known and the mean value - standard error control chart when the variance is unknown
然后，研究了扩散先验分布下单方程模型参数的贝叶斯估计理论，证明了模型系数的后验分布为多元t分布，模型误差项方差的后验估计为逆gamma分布；根据多元t分布和f分布之间的关系，构造了模型系数线性假设检验的贝叶斯方法；根据hpd置信区间构造了随机误差序列自相关的贝叶斯诊断和单位根检验方法，并利用单方程模型的贝叶斯推断理论研究了方差已知时的贝叶斯均值控制图和方差未知时的贝叶斯均值?标准差控制图。 - The paper analyzes the vertical stresses in soil based on geddes " assumption and stress formula , because the equivalent deep foundation is not appropriate when the lengths of piles are different . but the stress of bottom of pile is not accurate , so this paper modifies the fomula by integrating the mindlin formula . considering the model of elastic analysis method is different from the practice , correction factors nu n are introduced to get more accurate stress in soil
对于这种方法在分析桩端应力时出现应力集中的现象，对mindlin解重新积分来修正附加应力系数公式，以避免这种现象；由于弹性半空间和实际情况之间的模型误差会带来附加应力差距，通过大量的计算分析提出了修正系数m 、 n ，并给出了m 、 n随桩径、计算点深度变化的函数关系，最终使得应力的计算结果与有限元的计算结果十分吻合，而计算相对比较简便。 - The results showed that the blind beamforming algorithms could recover the desired source and null out the interfering sources . when the input snr was higher than the snr threshold , these algorithms could correctly estimate the doa . and the algorithms in thesis were robust to the model error of array geometry
结果表明，盲波束形成算法可以在捕获期望信号的同时，抑制干扰信号的输出，并在一定的输入信噪比门限下，准确、稳定地估计出目标方位，对阵列模型误差具有稳健性，且在高输入信噪比下，算法的角度分辨率不受瑞利限的限制。
