水听器的频响实验结果表明，当橡胶膜片的杨氏模量提高时，可以获得更为平坦的频率响应。
Experiments were carried out to test the frequency response of the hydrophone. The result shows that when the Young's modulus of the diaphragm is higher, a flatter frequency response will be obtained.
陀螺驱动频率响应曲线有两个谐振尖峰，在两峰值之间存在一个较平坦的区域。
The frequency response of the drive-direction oscillator has two resonant peaks and a flat region between the peaks.
为实现通带内频率响应平坦度高、滚降时间快的滤波效果，采用多环结构形成的高阶滤波器。
In order to achieve flatter tops and sharper rolloff in the passband, the multiple-ring higher order structure is employed.
