Here we used wavelet and spectral analysis to different kind seismic waves in volcanic area, in order to pick up their spectral character and determine the type of these earthquakes
本文對火山區不同種類的地震波形運用小波分析和頻譜分析的方法，希望能提取不同類型火山地震的一些頻譜特徵，確定火山地震的類型。 -
Expanding the system ' s hamiltonian to a real symmetric matrix in an appropriate orthogonal basis vector and then diagonalizing it, we get the energy spectrum of the system and calculate the energy level spacing distribution function and the spectral rigidity. then we study the statistical character of the energy spectrum under the changing of magnetic field intension and find that the system ' s motion transfers from regular to chaos gradually
將系統的哈密頓量在一個適當的正交基矢下展開並對角化，得到系統的能譜，分別計算系統能譜的能級間距分佈函數和譜剛度，研究了該系統量子能譜的統計特徵隨磁感應強度大小的改變而表現出的系統運動由規則到混沌的漸進變化。 -
