epicenter distance 中文意思是什麼
epicenter distance
解釋
震央距離-
In the case that hypocenter depth is far less than the epicenter distance without depth phases available, only the relative epicenter distribution could be obtained accurately by double difference method, the depth determined would be not stable
當震源深度遠小於震中距時，如果沒有深度震相的參與，只能得到誤差較小的震中相對分佈，深度的相對位置仍有較大的誤差。 -
Multi - channel deconvolution, based on multi - channel signal analysis, is presented to recover receiver function from three - component teleseismic p waveforms clustered within certain backazimuth and epicenter distance, to increase the resolution of receiver function. wavelet inversion is also introduced to broadband receiver function, to solve for nonuniqueness cased by linear approximation of nonlinear problem, and broadband receiver function is decomposed into multi - resolution versions, and the inversion result for the low - resolution version is iteratively taken as the initial model for the high - resolution, and gradually obtain the inversion model for broadband receiver function
為克服廣義線性反演對初始模型的依賴性，並保持其快速收斂的特點，本文首次將小波變換引入到接收函數波形反演，將接收函數分解到不同的分辨尺度上，分別進行廣義線性反演，並將低解析度的反演結果作為高解析度反演的初始模型，漸近地獲取寬頻帶接收函數的模型，克服了非線性問題線性化帶來的非唯一性。 -
The method of location prediction of strong earthquakes using stable intersection regions of the linear epicenter migration track with short time and long distance, is called “ the intersection method ”
由短期、長距離、線性震中遷移線交匯得到的穩定交匯區進行強震地點預報方法稱為線性震中遷移交匯法。 -
Based on the comprehensive statistical analysis of inelastic displacement ratios, the regression equations of - r - t about the strength reduction coefficient and inelastic displacement ratios are obtained. the effects of soil condition, earthquake magnitude, epicenter distance, damp ratios and hysteretic characteristics are considered in detail
通過對理想雙線性體系的均值彈塑性位移比與強度折減系數進行了統計分析與數值擬合，建立了兩大類場地土（硬土、軟土）下的- r - t回歸公式。
