本文研究了v_0及v_0为常数时,凹界面产生折射迴轉波的形成条件及其运动学与动力学特点,并在非纵折射野外观測中找到了实际的例子。当地震界面为大傾角曲界面时,在一定条件下会形成地震波时距曲綫的迴转。地震反射迴轉波的运动学与动力学特点,在文献[2,4]中已經討論过。理論上的推断,已由地震模拟实驗的結果加以証实。在本文中,主要希望尽可能浅近地来推导折射界面为一定曲率的圓弧形界面时,纵折射测线上折射迴轉波的形成条件。并以新疆地区某大断裂附近获得的非纵折射記录,来說明折射迴轉波的动力学与运动学特点。
In this paper, the formation conditions and the kinematics and dynamics of the refracted gyroscope at the concave interface are studied when v_0 and v_0 are constants. The practical examples are also given in the field observations of non-longitudinal refraction. When the seismic interface is a large-inclination curved interface, under certain conditions, the rotation of the seismic wave from the curve will be formed. The kinematics and dynamics of the seismic reflection wave are discussed in [2, 4]. The theoretical inference has been confirmed by the results of the seismic simulation experiment. In this paper, we mainly want to deduce as far as possible to the refractive interface of a certain curvature of the circular arc-shaped interface, the longitudinal refraction line reflection wave formation conditions. The non-longitudinal refraction records obtained near a major fault in Xinjiang are used to illustrate the dynamic and kinematic characteristics of the refracted gyroscope.
