In-liquid plasma evaporates a surrounding liquid by their heat and generates bubbles. As to the 27. 12MHz high frequency underwater plasma in 10-101kPa, simultaneous observation of two plasma emission distributions or a plasma emission distribution and bubble behavior was performed by assembling a high-speed camera and optical systems, such as a dichroic mirror. Excitation temperature distribution was calculated from two distributions of plasma emission. The periodicity of the cycle of the growth and the departure of bubble became more regular with the increase in a pressure. Just before the departure of the bubble the temperature in the bubble which was stretched between the electrode and the rising bubble was found to reach the maximum.

液体等离子体通过其热量使周围的液体蒸发并产生气泡。至于27。在10-101kPa的12MHz高频水下等离子体中，通过装配高速相机和二向色镜等光学系统，同时观测了两个等离子体发射分布或一个等离子体发射分布和气泡行为。根据等离子体发射的两种分布计算了激发温度分布。随着压力的增大，气泡的生长和离开周期的周期性变得更加规律。在气泡离开之前，在电极和上升气泡之间拉伸的气泡温度达到最大值。
