roll wave meaning in Chinese
滚动波
Examples
- It was not easy designing a radar system able to pick out a submarine peniscope from aimd the endless rolling wave father .
要设计一种能从不断翻滚的海浪回波中辨别出潜艇望镜的雷达系统，并非易事。 - Ground roll wave has characteristics of strong energy , low frequency and slow attenuation
摘要面波具有能量强、频率低、吸收衰减缓慢等特点。 - There are rolling waves , but even these have a relaxed , non aggressive personality to them
这里也有翻滚的波浪，但即使是这些翻滚的波浪也具有一种轻松的并不咄咄逼人的特性。 - By using band and equal distance wavelet transform and average energy method , the ground roll wave can be recognized and suppressed belier , hence obtaining good results
采用窄档等频距小波变换方法，在含面波的低频频带内，用平均能量法识别和压制面波，取得良好效果。 - In the low band of wavelet transform , energy of ground roll wave is normally greater than the average energy in overall band of seismic reflection event , which is regarded as the discrimination criterion for it
在小波分频后的含面波频带内，同一时刻较强面波能量总要比该时刻全排列的平均能量大得多，这是分频识别强面波的判别准则。
