Comprehensive analysis shows that, the primary wave travel - time under the satisfactory first interface and the secondary interface with slot is always longer than that under the first interface with slot, but is shorter than that of the formation wave, while the primary wave amplitude under the secondary interface with slot is smaller than that under the first interface with slot, but is larger than that under fully cementing condition
分析結果表明，第一界面膠結良好，而第二界面竄槽的初至波到時總是延遲于第一界面竄槽的初至波，但卻比地層波早，其幅度明顯小於第一界面竄槽的初至波，但比全膠結的幅度大。 -
In the primary experimental study, the microwave power, the microwave frequency, and the mode are measured, hie relations among the microwave radiation, the intensity of the magnetic field, the position of the magnetic coil, the amplitude of the beam current, and the a - k gap are investigated
在初步的微波實驗中，測試了微波的功率、頻率和模式，測試了磁場強度和線圈位置對微波輻射輸出的影響，測試了束流大小和陰陽極間距對微波輻射輸出的影響。實驗結果發現微波的功率和模式基本與模擬結果吻合，器件工作穩定，重復性良好。 -
Therefore the dynamical characteristic is acted as detected parameter for fractured detection ( primary amplitude secondary frequence ). and the amplitude of mean sguare and central frequence are acted as evaluational parameter, based on the those studies, the new ideas is put forward that fractured azimuth is dected by lateral difference and fractured density is dected by vertical difference for three facters of fracture, wavelet acted as analysis tool and direction by wave field characteristic applied the multiple scale edge dectection and self - adaptive edge detection into the detection theory of seismic fractured azimuth, also put forward the wavelet different scale filter method of the fractured azimuth detection
因而，確定了主要以振幅，其次是頻率的地震波動力學特徵作為裂縫檢測的被檢參數和均方振幅和中心頻率作為檢驗檢測結果正確與否的評價參數。在上述研究基礎上，針對裂縫的三要素，提出通過橫向求異檢測裂縫方位和縱向求異檢測裂縫密度的新思想。並以小波作為分析工具，以潛山波場特徵作指導，將數字圖像處理中的多尺度邊緣檢測和自適性邊緣檢測引用到地震裂縫方位檢測中來，並提出了小波變尺度濾波法新的裂縫方位檢測法。 -
For successfully applying ae on detecting crack during fatigue test, noise restraining, signal locating and the building of ae features database has been deeply investigated in this thesis. in brief, the following are the primary contents : by analyzing the source of noise, several methods of restraining the noise are proposed : space filter, amplitude filter, bp filter, parameters filter, hit time setting and illustrate analysis
