车辆周转强度

Intensity of Freight Car Circulation

本文在深入分析车辆周转时间θ局限性的基础上，提出超越θ的铁路运输新指标：车辆周转强度ｆ，并计算了我国铁路４５年（１９４９～１９９３）的ｆ实迹值，分析了ｆ作为综合评价车辆运用指标的效果。本文是《车辆周转时间指标体系的探讨》（见本刊１９８９年第１期）一文的续作。

On analyzing the limitation of index θ of freight car circulation, the author introduces a new index f which represents the intensity of freight car circulation. After the f values are computed. based on the railway performance records in the past 45 years (1949～1993 ), the merit of using f as on evaluation index for car circulation is assessed. This paper is a continuation of Probing of the index of Car Circulation Time .
