摘　　要：物质波的衍射与依靠介质传播的波的衍射有着本质的不同。依靠介质传播的波的实质是能量凭借介质的波动,从能量源向远处传播。物质波是一种粒子波,粒子自带能量。粒子在空间的某一点的动量不同。当粒子遇到观测屏时动量较大,在屏上形成明斑点;反之,当粒子遇到观测屏时动量较小或出现负值,则屏上形成暗斑点,这就是物质波衍射明暗斑纹的实质。The diffraction of material waves is fundamentally different from the diffraction of waves propagating through a medium.The essence of waves propagated through a medium is that energy propagates from an energy source to a distance through the waves of the medium.Material waves are particle waves that carry their own energy.Particles have different momenta at a certain point in space.When particles encounter the observation screen,their momentum is large,forming bright spots on the screen;On the contrary,when particles encounter the observation screen with small momentum or negative values,dark spots are formed on the screen.This is the essence of the light and dark spots in material wave diffraction.
