expansion ratio

基本解释

The large expansion ratio of liquid-to-gas can rapidly build pressure in systems where liquid can be trapped.
在液体受到束缚的系统里，液体到气体的大膨胀率能够迅速导致压力积累。
For any given portion of air, the greater expansion ratio allows more energy to be converted from heat to useful mechanical energy meaning the engine is more efficient.
对于任何给定的空气部分，更强大的扩展比允许更多的精力从热量转换为有用的机械能，这意味着发动机效率更高。
