这段路，你为什么不滑车省些油呢？

The children lined up for a coast down the snowy slope.

孩子们排队等着在雪坡上滑雪.

The driver turned off the engine and let the truck coast down the incline.

司机关掉了马达让卡车滑下斜坡.

Then, multi-ample coasting-own data and power calculation method were applied to verifying the results. The results show that the two-stage coast-down test method is correct and feasible.

采用多车速滑行试验法和功率法对两段法计算结果进行验证，证明了采用两段滑行试验法计算汽车滚动阻力系数和空气阻力系数的正确性。
