预报方程 meaning in Chinese
prognostic equation
Examples
- Contrast experiment shows that multi - time factors can improve the quality of prediction equations and make effective rate reach 90 . 0 percents and reduce sum of residual squares 23 . 8 percents meanly
对比试验表明，多时刻因子可改善大多数预报方程的质量，有效率达90 . 0 % ；多时刻因子使预报误差明显减小，预报方程的残差平方和平均减少23 . 8 % 。 - A diagnostic equation for n0s , the y - intercept of the assumed exponential snow distribution , is allowed to vary with snow mixing ratio . the scheme assumes a marshall - palmer distribution law for rain , snow and graupel with a constant intercept parameter n0
该方案将雪的m ? p分布谱参数截距n _ ( os )表达为雪的比含水量的函数，建立了n _ ( os )的诊断预报方程。 - Based on the dynamic frame of mm5 and reisner 2 explicit cloud scheme , a new double - moment microphysical scheme was developed , in which both the mixing ratios and number concentrations of cloud water , rain water , cloud ice , snow and graupel were predicted
从本质上说，该方案预报的仅仅是粒子的比含水量。在mm5动力框架内，在其中的reisner2方案基础上采用双变参数方案，增加了云水、雨水、雪和霰的数浓度预报方程。 - By use of correlation analyzing of temperature in heilongjiang province and previous general circulation or surface temperature , provision predictors are chosen to develop a predictive relationship of temperature anomaly in january or july of heilongjiang province with the theory of screening regression
通过对黑龙江气温与前期环流场和下垫面温度的相关分析，选取候选因子，用逐步回归的原理进一步筛选，建立黑龙江1月、 7月月平均温度距平的预报方程。 - This study uses quantitative remote sensing method on soil losses which based on 3s technique and supported by gis software to probe into the application of quantitative remote sensing method on soil losses . and according as the equations of soil losses ( a = fkrslcp ) & predicting soil conservation intensity ( y = cp - cp " ) to realize the 3s technique integration on gis platform in study area of longchuan river drainage basin
本研究采用基于3s技术的水土流失定量遥感方法，以gis软件为平台，以龙川江流域为试验区，依据水土流失方程( a = fkrslcp )和防治强度预报方程( y = cp - cp ' ) ，进行了在以3s技术为支撑的水土流失定量遥感方法的应用探索，实现了在gis平台上3s的集成。
