These electrostatic waves are considered as either the ion acousticmode evolution or the ion cyclotron mode evolution.
这些静电波被认为或者是离子声波模的演化，或者是静电离子逥旋波模的演化结果。

Results showed that the research under the concept of the acousticmode is significant in the efforts of reducing the noise level of ships.
结果表明，研究结构在声辐射模态概念下的噪声特性是船舶降噪研究中的一条新途径。

For the combustion instability driven by chemical reactions, the most inspirable acousticmode is the one whose wave abdomen is the most correlative with chemical reaction distribution.
