| 摘 要： | 分别用米氏散射和瑞利散射对钧瓷内小气泡和分相液滴的散射进行模拟计算,以对比两种计算方法的差异.通过对比计算,解析了钧瓷乳光产生的机理.计算结果表明,对于单个颗粒的散射,气泡的散射远远大于分相.气泡和分相的散射都是各向异性,并且波长越短,散射越强.但它们对短波选择的程度随粒子半径变化是不同的,小气泡是单调的,而分相液滴会有极值出现.

| Abstract: | The scatterings of minute bubbles and phase splitting drops in Jun ware are computed respectively with Mie scattering and Rayleigh scattering in order to compare the difference of two methods by which generant mechanism of Jun ware is analyzed. The result shows that for unit particle the scattering of bubbles is far and away stronger than that of phase splitting drops. The scatterings of both bubbles and splitting phase drops are anisotropic, and the shorter the wavelength is, the stronger the scattering is. The variations of the selection of shortwave with the particle radius are different. The variation of minute bubbles is monotonic, whereas there is peak for the case of phase splitting drop. |
