At the present time,the phenomena of many particles diffraction have been studied in many experiments,and these experiments have been explained by some theoretical works.We study the double-slit diffraction by a quantum mechanical approach.Starting from the Schredinger equation and using Kirchhoff's law,we obtain the diffraction wave functions for the double-slit.We find that when the effects of decoherece is considered in the C60 double-slit diffraction,the calculation results are in accordance with experimental data.
This paper get a general survey of advances in Wave Mechanics.The development of Wave Mechanics goes back to ancient times.The principle of least action is the source of Wave Mechanics,so it is the mother of several principles.Erwin Schrdinger was the greatest contribution scientist of Wave Mechanics,secondary was Louis de Broglie.The Schrdinger equation not only can treat the movement of microscopic particles,but also can analysed some of the macroscopic scientific problems.There's no time for Schrdinger to study the non-linear Schrdinger equation(NLS),but de Broglie devoted oneself to the study of nonlinear Wave Mechanics,and established contact with the solitary waves.At present,the most research works involve the nonlinear differential equations in mathematics,but ignore the physical meaning.In the sciences of waves,the study of electro-magnetic waves are important field,many problems demand clarification.From the Wave Mechanics point of view,we must integrate the classic electro-magnetic wave equation with the Quantum Mechanics wave eqution,the isolated discussion age of classic fields and waves was extremely early ended.
