边界辐射函数与衍射理论的关系

The relationship between boundary radiation function and diffraction theory

论述了基尔霍夫衍射理论的不自恰性,从数学和物理两个层面上进行了修正.根据辐射理论重新设定了平面衍射物的边界函数,并以此条件推导了基尔霍夫衍射公式,并赋予新的含义.讨论了衍射公式和边界函数的物理意义,分析了基尔霍夫错误的根源,给出了全新的、物理意义明确的边界条件.

The selfcontradiction problem of Kirchhoff diffraction theory is interpreted, and it is corrected from mathematic and physics. Firstly according to radiation theory the boundary function of planar diffraction body is given, based on this condition the Kirchhoff diffraction formula is deduced and obtained. The physical meanings are given as well.Secondry Then the physical meanings of the formula and boundary function are discussed. The origin of Kirchhoff's error is analyzed. The ultimate conclusion is that the new boundary condition with clear physical meaning is derived.
