脈沖 impulse; pulse; impulsion; out-burst; pip (熒光屏上的) 一個(gè)光脈沖 a pulse of light; 一個(gè)聲脈沖 a pulse of sound; 一個(gè)壓力脈沖 a pulse of pressure; 在低頻率(譬如每秒十次)時(shí), 所感覺到的是脈沖而非振動(dòng)。 at low frequencies, such as 10 per sec., pulsation is sensed rather than vibration
The white gaussian noise was successfully separated from noise signal in low - field pulse nmr system and its parameters were estimated by using this method 采用該方法從實(shí)際低場(chǎng)脈沖核磁共振系統(tǒng)噪聲信號(hào)中分離出高斯白噪聲并對(duì)其進(jìn)行了參數(shù)估計(jì)。
