This study is to clarify the influence of ultrasonic irradiation on foaming.The supercritical carbon dioxide was dissolved into the sample.Foaming was carried out in the hot water (temperature was slightly lower than Tg of PS) by irradiating ultrasonic in order to propagate effective ultrasonic to the sample.We used amorphous polystyrene (a-PS) as a sample because ultrasonic can affect the crystallization. The concave vibrator which can focus ultrasonic wave on the sample enhanced cell number density in comparison with the planar vibrator.The use of concave vibrator caused arrangement of cells with different size in laminae.

这项研究是为了澄清超声辐射对泡沫的影响。将超二氧化碳溶解在样品中。在热水中进行了泡沫（温度略低于PS的温度略低于PS的TG），通过对样品进行超声来传播效率的超声烯（我们使用的异源性多晶），因为它可以将其传播到一个样品中。与平面振动器相比，可以将超声波聚焦在样品增强的细胞数密度上的凹振动器。使用凹振动器会导致在层中具有不同大小的细胞排列。
