隨距衰減
英文
distance decay-
Based on the resolving algorithm of continuous - layer method, the time order analyzing curves, acceleration curves and the response spectra of transfer function at the different points of the ground and at the same point on the different ground conditions are gained. it demonstrates that the responses of ground in x, y and z axial directions all change by time, and the obvious wave propagation appears in ground. for different observing points on the same ground condition, at more distant points from the load line, the less swings are found, that is to say, vibration possesses the obvious characteristic of attenuation
基於分層法的解析演算法，得到了在不同點以及在同一點但不同地質條件下的時程分析曲線、加速度變化曲線和傳遞函數反應譜，結果表明，地基土在x 、 y 、 z三個方向的響應都是隨時間變化的，並且伴隨有明顯的波動現象產生；對于相同地質條件的不同觀察點，距離荷載作用線越遠的地方振幅越小，即振動具有明顯的衰減性。Consequently, the theoretical model for the accelerating flame in the re - intension process is developed, called shock - flame complex
實驗利用煙跡技術捕捉了爆轟波從發生衰減到再次加強的全過程，獲得了爆轟波再加強距離隨初壓變化的實驗規律。2 vibration : while vibration levels obviously diminish in proportion to distance, they are also significantly affected by soil type and the structural characteristics of support columns
（ 2 ）振動部分：捷運列車所造成之地表振動傳播，其隨距離地衰減的趨勢是很明顯，而衰減之程度則隨著土壤性質的不同及高架路軌樑柱之特性，而產生不同衰減變化模式。In a infinite and empty space the geomagnetic field falls off in strength with the third power of distance
在無限和真空的空間中，地磁場在強度上隨距離3次方而衰減。All records are classified into three site conditions. for the two components of a record, two energy equivalent spectra are calculated, and the geometric mean of the two spectra are adopted to analysis by two - stage regression method using an attenuation model. then the attenuation law is attained
對每一條記錄，取了兩個分量所計算的能量譜的幾何平均值，選擇了衰減模型，利用兩步回歸法，對這些能量等效速度譜做了統計擬合分析，得出了地震動四種能量反應譜隨震級、距離等參數的衰減規律。This paper discusses some problems in supersonic velocity measurement, and expounds, in the form of numerical computation, the availability results about supersonic energy attenuation adapting to distance, as well as the influential factors on the measurement
摘要該文討論了超聲波聲速測量實驗中出現的幾個問題，並通過數值計算，說明了超聲波能量隨距離的增大而形成的衰減趨勢，並對影響測量精度的因素進行了討論。The principium of the simplification criterion is that the light eradiated from surface will attenuate during it ' s transmission, so the light energy eradiate from the surfaces far from the viewer will become too faintness to attract the viewer ' s attention, thus the surfaces far from the viewer can be emerged into larger surface, then by combining with the residual light energy and terrain roughness, the new simplification criterion is formed
本文根據光能衰減原理，從人的視覺效果出發，認為由於地形面片輻射的光能將隨著距離增加而不斷衰減，所以距離視點較遠處的面片輻射到視點的光能必然很微弱，這樣就可以將遠處的面片合併成較大的面片，從而達到簡化地形的目的。Based on 266 strong ground motion records from 15 earthquakes in america, an attenuation relationship was used to relate energy spectra to earthquake magnitude, source - to - site distance, and site class. the purpose of this study is to make a foundation of energy - based design and seismic hazard analysis. the main achievements of this study could be summarized as follows : 1
本文的主要工作就是利用所掌握的地震動記錄，採用兩步回歸法對地震動的各種能量參數進行回歸分析，找出地震動的能量參數隨震級、距離等參數的衰減關系，為基於能量的方法能夠應用到抗震設計及震害評估等實際工程中奠定基礎。分享友人
