说明：  实现二十段赛段各段的油耗及耗时，累加得到总油耗和总耗时。如果总耗时超了，就自动调整增加四个加速段中若干段的加速度，再算。难点在于，滑行段的末速度得假设，然后计算平均速度各种阻力得出减速度得出末速度和假设的末速度不一致，要再次假设迭代，直到某次假设值和末速度相差在允许范围内（你自定），迭代完成。所得结果作为下一赛段的初速度，逐段计算。
(To achieve fuel consumption and time consumption in each section of the twenty stage, cumulative total fuel consumption and total time consumption are achieved. If the total time is over, it will automatically adjust the acceleration in some four acceleration segments. The difficulty is that the end velocity of the gliding section is assumed, and then the average velocity of all kinds of resistance is calculated to draw a decrease in the velocity and the final velocity is not consistent with the final velocity of the hypothesis. Again, the iteration is assumed again until a certain value and the final velocity differ in the allowable range (you are self determined), and the iteration is finished. The result is calculated at the beginning of the next stage. If you don't have a problem earlier.)
