directional properties meaning in Chinese
方向性
Examples
- The window inevitably imparts directional properties .
（计数器的）窗不可避免地具有方向性。 - 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 - And then , the paper analyses the reason engaged in the directional property of underwater acoustic transducer and array , discusses the physical parameter of the directional property . to point acoustic source equal spacing linear array , the dissertation makes experiment analysis and simulation
分析了水声换能器及基阵指向特性形成的原因、表征指向特性的物理参数，并针对点声源等间距线列阵的指向性进行了数学、实验分析与方针。 - 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。
