pulsating sphere
pulsating sphere 双语例句
The acoustical radiation power is expressed as a Hermitian quadratic form, while the radiation modes is determined by general eigenvalue decomposing, and then the radiation efficiency is computed via the orthodoxy of radiation modes with regards to impedance matrix and average velocity matrix; lastly, the validity of the method is proved by pulsating sphere and radiating cube with analytical results.
先将结构的声辐射功率表示为一个正定的厄米特二次型,运用广义特徵值分解求解了复杂结构的声辐射模态,然后利用声辐射模态关于阻抗矩阵与均方速度祸合矩阵的正交性,求解了复杂结构的声辐射效率,最后用具有解析解的脉动球与辐射立方体验证了该方法的有效性。
Taking a pulsating sphere as an example, some parameters in its sound field are calculated.
并以脉动球作为算例,对其辐射声场中的有关声场参数进行了计算。
