scattered signal
解釋
散射信號-
Going even lower, there is a more subtle, scattered, and more medially distributed region of abnormally high signal
在向更低的平面，可以看到異常高信號散落分佈在一些細小區域。 -
The light signal back - scattered from wake bubbles can be detected by taking some measures
採取一定的措施，尾流氣泡後向光散射信號是可以探測到的。 -
The principle of vibrator is to introduce scattered energy to underground in a comparatively long time, and collect the energy through correlation and compress it into a narrow pulse. the portable high - frequency vibrator system, developed by key lab of geo - exploration and instrumentation ( jilin univ ), ministry of education, generates chirp signal and accumulates energy through a long - time bestiring. according to the characteristics of vibrator, the seismic recorder that operates on - line with vibrator must have these functions as follow : first, it must have the ability of recording a great quantity of data. second, it must have assistant channels to sample reference signal. third, it must have the function of data correlation in real - time
可控震源利用可控的小能量、長時間激發波來實現沖擊震源瞬時產生的大能量激發波。在利用可控震源進行地震勘探時，要求地震儀長時間記錄地震信號，這對地震儀的采樣長度提出了很高的要求。受存儲量和數據傳輸速度的限制，絕大多數地震儀很難對如此大的數據量進行記錄，同時，可控震源要求地震儀有兩個輔助通道並且具有數據相關功能，目前國內還沒有出現滿足要求的地震儀產品。 -
The conclusions are as follows : the ultrasonic intensity is proportion to the laser intensity ; the ultrasonic induced by a laser line source has much more advantages than by a laser point source, such as stronger energy, higher snr, more directivity and shape ; the intensity of cfpi ' s output signal is linear with ultrasonic vibration velocity, and is effected by incidence angle and scattered angle ; snr will increase by reducing cfpi ' s bandwidth, reducing incidence angle, increasing cavity ' s length and reflectivity
在分析點光源激勵聲表面波機理的基礎上，求出了線光源激勵的超聲振動的位移表達式，發現線光源激勵的近場區表面波具有波形好，信噪比高，指向性好，幅度強等特點。通過理論推導，得出共焦fabry - perot干涉儀的輸出光強除了與樣品表面的振動速度成正比，並與入射角和散射角有關；適當減小cfpi的帶寬，增加腔長，增大鏡面反射率，或者減小檢測入射角都可以提高系統的信噪比。 -
In the experiment, the scattered background neutrons is studied with the shielding method and the scattered background neutrons in the experiment hall is eliminated from signal neutrons by the method of combining the shielding experiment ' s results with the mcnp / 4a code calculation
