And by a monotone integral operator , we give an asymptotic approximation way which is further improving the older ways
并且使用一个具有单调性的算子，给出了一种更实用更有效的对破产时刻赤字分布函数渐进估计的方法。
It is well known that the coupled interactions between the ship hull and the surrounding fluid field of explosion give rise great influence to both the fluid loadings over the structural wetted surface and the responses of the hull . jt is the coupling effect that provides the major difficulties in the underwater explosion induced dynamic responses of the ship structure . the second order doubly asymptotic approximation method ( dda2 ) has been commonly employed in the world to deal with the coupling effect
本文针对daa方法不适合于分析敷有声阻抗与水差不多的声学材料(如玻璃钢与消声瓦)的船体结构与水下冲击波相互作用的局限性，依据声波的反射和透射原理对二阶daa方法的高频段进行了改进，发展并提出了能够分析声学材料流固相互作用的adaa方法( acousticdaa ) ，拓展了应用范围，使现有的二阶daa方法成为它的一个特例。
In the theoretical description of grazing emission fluorescence , the mode of fluorescence intensity emitted from layered materials dependence of grazing angle is established by applying asymptotic approximations to double fourier integrals , and the theoretic calculation formula of fluorescence intensity from a thin layer is derived . by the derived expressions , the theoretic simulation curves of several thin layers on si substrate are calculated . in the experimental setup , the requirement of construction of the setup and some important parameters are brought forward
最后，利用平稳位相方法建立了掠出射情况下薄层样品产生的荧光强度和掠出射角的对应关系数学模型，推导了薄层样品荧光强度理论计算公式，并以此为依据模拟计算得出了cr 、 fe 、 ti和ni等几种以si作基底的单层薄膜样品的荧光强度随掠出射角变化的理论曲线。
