瞬態聲波 的英文怎麼說
中文拼音 [shùntàishēngbō]
瞬態聲波
英文
transient acoustic waves-
The wavelet method is applied to analyze the transient record of cavitation noise of bubble collapse successfully
同時引入了小波方法對瞬態的空化噪聲信號進行了分析,取得了良好的效果。Design of an ultrasonic transducer for measuring transient high temperature
用於瞬態高溫測試超聲波傳感器By means of the corollary of 3. 5 which stated that carrying on double wavelet transform to the signal would not change the convergence of modulus maxima line when scale comes to zero, this thesis put forward a new measuring method
當信號中混入較大的噪聲時,這種方法仍然可以實現瞬態信號波至點的精確檢測。採用matlab及wavelab工具箱對本論文所提出的方法進行設計及模擬研究。Digital wavelet frame denoise the transient scatter response signals
離散小波框架消除瞬態散射回波噪聲In vibration test, the signal is always along with noise. if the noise belongs to white noise, fourier transform is very suit to identify and process it, after then remove it. but when there exists low energy impact signal, traditional band pass filter remove noise and the precise position of impact signal is blured
對于白噪聲,由於它是穩定信號,所以也可以使用fourier變換定位,以便在合適的頻段進行提取。但是對于低能量突變瞬態信號,在信噪比比較低的情況下,由於帶通濾波的平滑作用,瞬態信號的位置信息也變得很模糊了。Adopting noise - initiation mode of stimulated brillouin scattering ( sbs ), the transient sbs equations are numerically solved, and the intensity distribution of transmission beam when the gaussian beam passes brillouin medium is simulated
