边界反射 meaning in Chinese
edge reflection
Examples
- The absorbing boundary conditions to avoid the artificial boundary reflections must be required in the numerical simulation of seismic wave propagation
摘要在地震波传播数值模拟的过程中，需要使用吸收边界条件从而达到衰减人为边界反射的目的。 - The snapshots of the theoretical and salt model show that they reduce artificial reflections to a great extent and absorb energy over a wide range of incident angles
理论模型及三维盐丘地质模型波场切片快照试算结果表明，该吸收边界条件可以有效地吸收人为边界反射，适用于较大入射角情况，从而消除了边界有效波信息的干扰。 - It was found that after our careful processing of the absorption boundary for artificial reflection , we could use the time - trace records at the surface to invert the locations of seismic sources or underground scatterer accurately
经由适当的消除人为边界反射，在只利用地表的历时记录即有效的推求出震源及散射体的精确立置。 - Compared with the initial value problem , the weak entropy solution of the initial - boundary value problem includes the following new interaction type : a central rarefaction wave collides with the boundary and the boundary reflects a new shock wave which is tangent to the boundary
与初始值问题相比较，初边值问题的弱熵解包含了以下新的相互作用类型：中心稀疏波与边界相撞，边界反射出一个与之相切的新激波。 - In this paper , deconvolution and linearized inversion of receiver function are improved ; multi - channel deconvolution and wavelet inversion are developed for receiver function . the elastic wave motion equation is applied in the simulation and migration of receiver function in lateral inhomogeneous media , multi - grid algorithm is introduced in numerical modeling of elastic wave motion equation , and phase - delay boundary condition is also provided to absorb boundary reflection
在此基础上，重点研究和发展了横向非均匀介质中，基于波动方程的数值模拟与偏移成像方法，首次将多重网格算法引入到弹性波方程的数值模拟和接收函数的偏移成像，还发展了一种延迟边界方法，以消除人为边界反射的影响。
