The combination of soil layer has negligible effect on the p - wave propagation . 4 the effect of complex media basin on seismic wave propagation the significant parameters controlling the propagation in basin contain sediments / bedrock shear - wave velocity contrast , sediment depth and the degree of saturation 4 、复杂介质情况下盆地对地震波传播的影响基岩与沉积层的剪切波速比、沉积层的深度、沉积层的饱和度是影响地震波在沉积盆地中传播的重要因素。
Therefore , xigeda filling material is a compounding filling made up of several soft rocks mentioned , which has more complex medium feature than single type filling material . we must certificate whether it satisfy minimum intensity standard of speedway ' s filling if the filling is used as roadbed material of express highway 因此昔格达填料是由上述几类软岩组成的混合填料,与单一类型填料相比具有更为复杂的介质特征,将其用作高速公路路基路堤填料,需要验证其能否满足高速公路对填料的基本要求。
In the areas of radar stealth and anti - stealth technology research , radar target identification , complex antenna system design and modern electric systems ’ emc analysis , we often need to simulate the electromagnetic characteristics of some electric large objects which is composite of complex structure and complex medium 在雷达目标隐身和反隐身技术研究、雷达目标特性识别、复杂天线系统设计、现代电子系统电磁兼容性分析等领域,经常需要对一些具有复杂结构和复杂媒质组成的三维电大尺寸目标作电磁建模。
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 电离层是随机时变,各向异性,非均匀、色散的复杂介质。为了保证依赖于电离层进行的短波通信质量,必须了解电离层的实时状态信息。高频返回散射探测可以实时监测与短波通信或高频天波雷达相关的天波传播信道的状态,对短波通信和天波雷达工作起了重要的辅助作用。
