类椭球体放矿理论移动过渡方程的研究

为优化类椭球体放矿理论,在建立类椭球体放矿理论移动过渡方程的基础上,根据质量守恒定律,推导出理想散体的移动过渡方程;进一步分析实际散体放出过程中的质量平衡状态,建立了实际散体的移动过渡方程。研究发现,理想散体移动过渡方程是实际散体移动过渡方程η=1时的特殊方程。研究结果丰富了类椭球体放矿理论的理论基础。

ELECTROMAGNETIC SCATTERING BY A PERFECTLY CONDUCTING GRATING IN A HOMOGENEOUS CHIRAL ENVIRONMENT

The scattering of plane time-harmonic electromagnetic waves propagating in a homogeneous chiral environment by a perfectly conducting grating is studied.The problem is simplified to a two-dimensional scattering problem,and the existence and uniqueness of solutions are discussed by an integral equation approach.
