  1. The ionosphere is a complex medium, which is aeolotropy, asymmetry, dispersive and changes randomly with time. in order to improve the communication quality of the shortwave that depends on the ionosphere, we should have aknowledge of the current condition of the ionosphere in real time. the backscatter sounding of high frequency can diagnose the real - time channel characters for shortwave communication or hf radar, which is great assistant to shortwave communication and hf radar

    電離層是隨機時變，各向異性，非均勻、色散的復雜介質。為了保證依賴于電離層進行的短波通信質量，必須了解電離層的實時狀態信息。高頻返回散射探測可以實時監測與短波通信或高頻天波雷達相關的天波傳播通道的狀態，對短波通信和天波雷達工作起了重要的輔助作用。
  2. In this paper, the authors study the mathematical model for seismic wave propagation in complex underground medium, discuss the boundary element method for solving seismic wave equations in frequency - domain, and investigate the computational formation of separation of wave equations in frequency - domain

    摘要分析了復雜地下介質情形地震波傳播的數學模型，討論了地震波數學模型數值求解的頻率域邊界元方法，並得到波動方程頻率域邊界元法的離散化計算公式。
