The variable displacementpump operates in only one of the first and second pumpdisplacement settings.
变量泵仅运行在第一和第二泵排量位置中的一个位置上。

The design principle is to decrease the pump velocity, reduce stroke or to use a small pump to reduce the pumpdisplacement and keep proper submersible depth.
设计原理是减慢泵速、缩短冲程或改用小泵来降低排量，保持适当的沉没深度。

Stimulated Raman scattering signal wavelength is like making a longer wavelength signal path or spontaneous Raman scattering of a Raman - displacementpump.
