正规过程和倒逆过程讨论完整晶体中声子-声子散射问题时,由于要求声子波矢为简约波矢（见布里渊区），所得到的总波矢守恒条件会相差一个倒易点阵矢量G)。例如对于三声子过程有下列条件 ，(1)式中q1和q2是散射前的声子简约波矢, q3为散射后声子波矢，式(1)中G)的取值应保证q3也是简约波矢。这时会出现两种过程,其一是当q1+q2在简约区内时,可以取倒易点阵矢量G)＝0,式(1)则简化为总波矢守恒条件,称为正规过程或N过程。其二是当q1+q2超出简约区时,所取G)应保证q3仍落于简约区内,由于q3与q1+q2相差G),显然q3位于q1+q2的相反一侧，这时散射使声子传播方向发生了倒转，故称为倒逆过程或U过程。U过程总波矢不守恒,但总能量守恒,因为声子频率是倒易点阵的周期函数，而q3与q1+q2只相差一个倒易点阵矢量。N过程在低温长波声子的散射问题中起主要作用。当温度升高，简约区边界附近的声子有较多激发时，U过程变得十分显著,它对点阵热导有重要贡献。在能带电子与声子散射问题中存在着与式 (1)相仿的总波矢条件k+G＝k┡±q，(2)式中k与k┡分别为散射前后电子的简约波矢,±号分别对应于吸收或发射q声子。类似的在热中子-声子散射以及晶体中一切波的相互作用过程中，总波矢变化都相差一个倒易点阵矢量G),因此也都有N与U过程之分。这是晶体和连续媒质不同之处，连续媒质对无穷小平移具有不变性，才能求得总波矢守恒，而晶体只具有对布喇菲点阵的平移不变性，因此总波矢守恒条件会相差一个倒易点阵矢量。
