垂直指向性 meaning in Chinese
vertical directivity
Examples
- The analytic result derived by studying the vertical directional property shows that , the vertical sensitivity distribution is homogeneous and the fluctuation is 0 db in theory . the fluctuation observed in experiments is less than 0 . 3db , which agrees well with that in theory
垂直指向性分析结果表明,光纤水听器垂直方向的灵敏度分布是均匀的,理论上波动应为0db ,而实验测得的垂直方向的指向性波动小于0 - This paper investigates the pressure sensitivity of an interferometric fiber - optic hydrophone element with a concentric mandrel including an enhanced sensitivity layer based on the theory of elastic mechanics and finite element method ( fem ) and then investigates its harmonic frequency and vertical directional property using fem , and verifies all the results derived from theoretic analysis at last
本文分别基于弹性力学的理论和有限元的方法对含弹性增敏层的同轴干涉型光纤水听器基元的声压灵敏度进行研究,并基于有限元的方法对其谐振频率和垂直指向性进行分析,最后用实验对各项分析结果进行了验证。
