epicenter distance meaning in English
震央距离
Examples
- 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
当震源深度远小于震中距时，如果没有深度震相的参与，只能得到误差较小的震中相对分布，深度的相对位置仍有较大的误差。 - 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
通过对理想双线性体系的均值弹塑性位移比与强度折减系数进行了统计分析与数值拟合,建立了两大类场地土(硬土、软土)下的- r - t回归公式。 - 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
为克服广义线性反演对初始模型的依赖性，并保持其快速收敛的特点，本文首次将小波变换引入到接收函数波形反演，将接收函数分解到不同的分辨尺度上，分别进行广义线性反演，并将低分辨率的反演结果作为高分辨率反演的初始模型，渐近地获取宽频带接收函数的模型，克服了非线性问题线性化带来的非唯一性。
