image theory

Principle of hydrodynamic images
铃力学镜像原理
The text uses the method of ray tracing that is based on improved traditional mirror image principle of the radio wave forecast and two ray propagation model , which can be used in any complex propagation environment and found any propagation path from the sending set to receiving machine without redundancy computer
本文是基于无线电波预测中传统的镜像原理与双射线传播模型的结合而提出的改进了的射线跟踪算法,它能用于任何复杂的传播环境中,能找到从发射机到接收机之间的所有传播路径而无须冗余的计算。
On the basis of the stresses analysis , the existed design rules of pressure tunnels are discussed . first , the pore - water - pressure distribution in the rock mass around the pressure tunnel is evaluated using the image well method proposed by harr ( 1962 ) . the seepage - induced stresses in the rock mass is analyzed , and several conclusions are gained
首先，运用harr ( 1962 )镜像原理推求压力隧洞围岩中水压力分布；结合水压力的分析，利用fernandez ( 1994 )的假定推求压力隧洞围岩中渗流产生的应力场，并对不同地表条件下渗流产生的应力场进行详细分析，从中得到一些结论。
