现了悬浮水滴各振动模式与半径区间的对应规律.理论和实验指出悬浮液滴被两个阈值分为三种主要模式; 半径小于下阈值，

悬浮液滴因表面张力缩成水珠状; 半径大于上阈值，液滴内外气压差过零，破坏原有振动，表现为液滴底部产生大气泡的现象.

effect and the threshold radius of Leidenfrost stars in various stages. It is found that the vibration modes of floating

droplets correspond to radius range. Both the theoretical and experimental results indicate that floating droplets are

divided into three main modes by two thresholds. When the radius is smaller than the lower boundary of threshold，

droplets are contracted to a spheroidal one because of surface tension; on condition that the radius is larger than the

outer boundary of threshold， the pressure difference between the inner and external part of droplets is negative，

which destroys the original vibration of droplets and forms a bubble at the bottom of droplets. In this case that floating

droplets between two modes， forms Leidenfrost stars and the modes of stars is linearly enlarged with the increase

of radius. In contrast， the modes of stars decrease with evaporating.
