 The theory of singular perturbations is used to a find a two-term asymptotic expression for the film thickness h0. The Washburn equation  can be used as an intermediate asymptotic expression in such cases. A second-order asymptotic expression for the profile of a capillary-gravity wave traveling over the charged surface of an ideal incompressible fluid is calculated analytically. In the finite case, we obtain an asymptotic expression, asn → ∞, for the number of matrices with zero permanent. This estimate implies an asymptotic expression for the solution indicating the presence of a track behind the body. 更多 The diffracted field of a sound pulse source in a moving stratified medium, in which a shadow zone may be formed, has been studied theoretically.

The diffracted field of a sound pulse source in a moving stratified medium, in which a shadow zone may be formed, has been studied theoretically. The fundamental equation is reduced to an inhomogeneous linear differential equation of second order by a mixed integral transform, and the solution is expanded into a series of normal modes. Following the method developed by Friedlander, asymptotic expressions of eigen value and eigen functions are derived from Langer's asymptotic solutions. The approximate formula of the field near the diffracted front is obtained for the observing points far inside the shadow boundary. Based on this formula, the establishing process and the attenuation with horizontal distance of field are discussed respectively. These relations are strongly dependent upon the boundary condition and the situations of source and receiver. 本文研究了作定常无旋运动的分层介质中形成影区条件下一δ型脉冲点声源的衍射场.用混合积分变换将运动介质声学基本方程化为一非齐次线性二阶常微分方程,并将它的解展开成各阶简正波之迭加;运用Friedlander所发展的方法由Langer渐近解求出本征值和各本征函数的渐近表式;对于深入影区边界之内的观察点得到了波前附近场的渐近表式.根据这一表式讨论了场随时间的建立过程和随水平距离的衰减关系.这些关系强烈地依赖于边界条件以及声源和接收点是否位于界面上这一情况.
