最後，他以自身的經驗指出，觀音法門可以充分開發腦波來發展天賦，讓人輕鬆快樂，增進學習效率。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。In principle, ultrasonic sensors are suspended over a road, which keep emitting pulse signals periodically to nearby and feed back waves to decide existence of any obstacles, thus to detect the speed, height, length, different sizes ( heavy, medium and small ) of moving vehicles and accumulative flow as well as length of motorcade. optionally, it can be applied to multitude driving lanes simultaneously for traffic data. by integrating and analyzing these measured data, the necessary figures concerning traffic flow may be obtained, which are fundamental basis guiding road buildings

通過對這四種小波的結構地震反應分析研究說明： littlewood ? paley小波不適合於用來作結構地震反應分析，因為在littlewood ? paley小波下的結構地震反應太小，不符合實際情況；用meyer小波作結構地震反應分析比較合適，和有限元法的結果比較接近；也可以用諧波小波來作結構地震反應分析，只是在諧波小波下的結果略為偏大；單邊指數小波下的結構地震反應分析比有限元法稍大一點，它通過小波變換大大簡化了結構地震反應分析。用小波變換方法來進行結構地震反應分析和以往方法不同的是：它不僅可以知道地震波的具體頻率段對結構反應的影響，而且同時考慮了地震波的幅值非平穩性以及頻率非平穩性；另外與以前方法得到的結果有差異的是，第二振型及以後的高一點的振型的反應沒有以前的方法衰減得快。分享友人
