常見例句雙語例句The method can be used to both crystal crystal and isotropic medium crystal interfaces.這一方法既能應用于晶體-晶體界面，也能應用于各向同性媒質(zhì)-晶體界面。However, coal is usually assumed to be an isotropic medium in the traditional coal seismic exploration, and the impacts of fractures on seam are not taken into account.傳統(tǒng)的煤田地震勘探將煤層假設(shè)為單一的各向同性介質(zhì)，沒有考慮其中裂隙對煤層的影響。By use of coordinate transformation, the multilayered anisotropic medium is changed into a homogeneous isotropic medium and a theoretical T-D equation of seismic reflection wave is derived.利用坐標變換方法，將多層的各向異性介質(zhì)轉(zhuǎn)換成均勻各向同性介質(zhì)，從而推導出地震反射波理論時-深方程。通過模型的測定，介紹了各向異性系數(shù)的求取及地質(zhì)剖面的構(gòu)制方法。 返回 isotropic medium
