波长单位
wavelength unit
- 波长的一个专门单位Angstrom (A，埃)就是为了纪念他在光谱学方面的成就。
A special unit of WAVELENGTH, the ANGSTROM (a), now honors his accomplishments in SPECTROSCOPY. - 介绍用相位测距仪实现波长标准及在大长度范围内传递长度单位尺寸的情况。
The situations of realizing wavelength standard with phase diastimeter and transmittinglength unit size within a large range are introduced. - 通过CFD的方法能够对问题进行细致的研究，但是要求单位波长上包含大量的网格点来从数值误差中识别声波。
With the aid of CFD, the problem can be studied in detail, but this requires a very large number of points per wavelength to distinguish the wave form numerical errors.
