The first law tells us that work output cannot be produced without an equivalent amount of energy input. 第一定律告诉我们,如果没有等当量的能量输入,就不可能产生输出功。
Non-inertial cavitation is the process where a bubble in a fluid is forced to oscillate in size or shape due to some form of energy input, such as an acoustic field. 非惯性的气穴现象是泡沫在一种液体中由于一种能量输入的缘故被迫在体积和型态上震动。
