dynamic roughness meaning in English
动力糙度
Examples
- It is different from traditional concept that the concept dynamic roughness includes influence of model error , truncation error , observation error and so on
此时的糙率与传统的概念有明显的不同，它包含了模型误差，截断误差，观测误差等各方面的综合影响。 - One dimension river flow roughness parameter inverse analysis kalman filter is introduced into the model to solve stochastic error in observed data . applying kalman filter automatism revising system , dynamic roughness course is obtained . using dynamic roughness course the model result precision is improved , it is more consistent with observed data
对于一维河道糙率参数反分析，针对观测资料存在的随机误差，引进卡尔曼滤波器的自动校正系统，求解出河道糙率变化的动态过程，使用动态糙率计算，明显改善模型的模拟精度，使模拟过程和观测过程很好吻合。
