求翻译：引言：利用等厚干涉，由同一光源所发出的光，分别经过其装置所形成的空气薄膜上下表面反射后，在上表面相遇产生的干涉。根据薄膜干涉原理,用两个很平的玻璃板间产生一个很小的角度,就构成一个楔形空气薄膜,用已知波长的单色光入射产生的干涉条纹,可以测量头发丝的直径。是什么意思？

Introduction: the use of equal thickness interference, light emitted by the same light, respectively, after the installation of air formed by the upper and lower surface of the film after reflection, the interference generated on the surface of the meet. According to thin-film interference principle

Introduction: use thick interference, such as by the same light source light of respectively, after its installation formed by surface air films after reflection on the surface, resulting from the encounter interference. In accordance with principles, thin-film interference in a glass with one very

Introduction: the use of interference of equal thickness, by the same light source emitted by light, respectively after its plant after air thin films formed by upper and lower surface reflectance, surface meet on intervention. According to the principles of thin-film interference, between two flat
