【摘要】 利用肥皂膜的等厚干涉原理,研究了竖直面内肥皂膜条纹位置及薄膜厚度的分布规律,发现竖直面内肥皂膜的厚度为微米和亚微米量级,其分布随着成膜时间的变化而变化:在肥皂膜形成初期,膜厚分布近似于"铃铛"形;在肥皂膜形成中期,膜厚分布为标准的楔形;而在接近破裂时其形状类似于倒立的"漏斗"形。更多还原

【Abstract】 Distribution properties of soap fi lm in vertical plane are investigated via equal thickness interference theory. It is found that the thickness of soap fi lm is of micron or sub-micron orders, and the distribution properties are changing with forming time. At the beginning, the soap fi lm is bell-shaped, at the middle time, the soap fi lm is wedge-shaped and when the soap fi lm is going to broke the soup fi lm is upside down funnel-shaped.更多还原
