We are developing a bubble-projection three-dimensional display (BP3DD) that will generate reflecting points in a liquid. We examined bubble generation in water and ethanol to find the most suitable conditions for the BP3DD. Experimental results showed that when the water pressure was lower, the required energy to generate bubbles decreased linearly. The required energy should be lowest when the water pressure is similar to the water vapor pressure. When bubbles were generated in ethanol solution, the required energy was lower than that required in water. The minimum required energy to generate bubbles was approximately 2 J. We can conclude that the required energy to generate bubbles is dependent on the physical properties of the liquid and its pressure.

我们正在开发一种气泡投影三维显示器（BP3DD），它将在液体中产生反射点。我们检查了水和乙醇中的气泡产生情况，以找到最适合 BP3DD 的条件。实验结果表明，当水压较低时，产生气泡所需的能量呈线性下降。当水压与水蒸气压相似时，所需能量应最低。在乙醇溶液中产生气泡所需的能量比在水中低。产生气泡所需的最小能量约为 2 J。我们可以得出结论，产生气泡所需的能量取决于液体的物理性质及其压力。
