1) annulus
[英]['ænjuləs] [美]['ænjuləs]
环形隙缝
2) annular micro-gap
环形缝隙
3) ring slit flow
环形缝隙流
1.
The concentric ring slit flow theory of fluid mechanics ,which is flow rate and pressure difference formula ,is usually used for analysis, research and engineering calculation in hydraulics problems, but the formula origin in general references which is based on the ordinary analysis of parallel plate (plain) pressure flow theory is not refined mathematics analysis .
在液压技术问题的分析,研究和工程计算中,经常要用到流体力学中的同心环形缝隙流理论,即流量—压力差公式Q=πdh3Δp/12μL;而通常的研究中并未对这一公式由来作过严格的数学分析,只是根据平行板(平面)压差流理论作出变通分析而得出的结论。
4) square-loop slot element
方环形缝隙
1.
The mechanically tunable characteristics of double-layer FSS(frequency selective surface) with square-loop slot elements is studied under normal incidence and 45° oblique incidence of plane wave with TE and TM polarization.
研究了双层方环形缝隙频率选择表面(FSS)在正入射和TE、TM波45°斜入射情况下借机械平移调谐频率的特性,结果表明:该频率选择表面具有较好极化和入射角度适应性;按2。
