source-axis distance
解釋
源-軸間距-
In the process of trick source infiltration, the increased soil water content is a constant value 0. 34 for clay loam soil. the distribution pattern of water content in horizontal is similarly with vertical level. the more of the distance away axis, the less of the soil water content, and the decrease is most notable near the wetting front
土壤濕潤體內含水率在水平方向上的分佈，表現為在同一水平剖面上隨著與對稱軸之間距離的增加，含水率不斷減小，減小的幅度在接近濕潤鋒處最為明顯；土壤濕潤體內含水率在垂直方向上的分佈，亦表現為在同一豎直剖面上隨著深度的增加，含水率不斷減小，減小的幅度在接近濕潤鋒處最為明顯。 -
When the vertical formation lies outside of the borehole, the effect of the borehole on the acoustic field decreases with the increase of the distance between the formation and the axis of the borehole ; when the source locates on the interface, with the increase of the azimuth of the dipping interface, the transmitted energy of the horizontal component gradually increases, but that of the vertical component decreases
當井外存在徑向分層時，隨著地層界面遠離井軸，對井內聲場的影響減小。 2 、當聲源位於地層界面以上時，隨著地層傾角的增大，水平分量透過地層界面的聲能量是逐漸增大的；垂直分量的透射聲能量卻是減小的。
