When a collimated laser beam illumines the curved liquid surface by the wetting rod, the special reflective patterns, which correspond to the boundary light reflection, can be produced. In fact, there is the pattern with dark central region and the high visibility diffraction fringes around, and the radius of dark region largen with the reduced radius of the incident beam.

当平行激光束垂直入射到由细棒润湿效应引起的弯曲液面上时，边界反射产生特殊的反射图样，图样的中心为圆形暗场，周围有清晰的衍射条纹，并且暗场的半径随入射光束半径的缩小而变大。

Inthis paper, a new method is presented, in which we measure the thickness ofsurface film layer by means of measuring the distance between correspondingtwo dark lines in two groups of white light interference fringes that are res-Pectively produced by two beam reflected by two surface of the thin filmlayer and another beam coming from another arm in Michelson interferome-t...

本文提出一种新方法，它利用迈克耳逊干涉光路，通过对膜层前后两表面反射光束和来自另一臂的反射光束产生的两组白光干涉纹黑线间隔的测量，即可得到表面膜层的厚度、这种测量方法迅速、简便、设备简单、精确度高、不损伤膜层表面，适合在实验室和工厂广泛应用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
