The constant reversal of the piston travel sets up inertia forces, which increase Both with the weight of the piston and with its speed.
活塞的不断往复运动产生了惯性力，惯性力随活塞的重量及其速度的增加而增大。
The plane uses a piston engine rather than a large-scale turbine jets, allowing it to travel unaffected through the ash, unlike large commercial jets.
该飞机使用活塞式发动机，而不是身材庞大的喷气涡轮机，因此它不会像大型商业飞机那样受到火山灰的负面影响。
This would allow the piston to travel up farther before the port is closed thereby reducing the power loss.
这将使活塞旅行了更远的港口前关闭从而减少功率损耗。
