引入了可测量坐标和自旋投影的层析概率分布来描述量子态，作为密度矩阵的替代。对于这样的概率分布，得到了与自旋1/2粒子的Pauli方程类似的结果，而不是通常的波函数方程。给出了带电粒子在恒定磁场中运动的朗道能级和相干态的层析描述的例子。
The tomographic-probability distribution for a measurable coordinate and spin projection is introduced to describe quantum states as an alternative to the density matrix. An analogue of the Pauli equation for the spin-½ particle is obtained for such a probability distribution instead of the usual equation for the wavefunction. Examples of the tomographic description of Landau levels and coherent states of a charged particle moving in a constant magnetic field are presented.
