重力模型 meaning in English
gravitational model
gravity models
Examples
- Earth gravitational model
地球重力模型 - Prior to applying a gravity model , one has to calibrate the impedance function
应用重力模型的之前，你应该先校准阻抗函数。 - The gravity model explicitly relates flows between zones to interzonal impedance to travel
重力模型明确的通过地区间的阻抗来将分布量和小区联系起来。 - Calibration typically entails an iterative process that computes coefficients such that the gravity model replicates the trip length frequency distribution and matches base year productions and / or attractions
典型的校准在系数计算中通常有一个迭代过程，好像重力模型复制了出行距离频数分布，同时匹配基年发生和吸引。 - Gravity model : the typical inputs include one or more flow matrices , an impedance matrix reflecting the distance , time , or cost of travel between zones , and estimates of future levels of productions and attractions
重力模型：输入的基本数据包括一个或多个流量矩阵，反映距离的阻抗矩阵，小区间的出行时间和成本，未来发生和集中预测。
