本文叙述了1928-1929年Kapitza发现金属中线性磁阻的历史及其解释。事实上，卡皮扎发现了两种不同的现象。其中之一，Lifshits和Peschansky在1958年解释了具有开放费米表面的金属多晶样品在经典大磁场下的线性磁阻。另一种现象是量子线性磁阻出现在金属或半金属中，当只有最低的朗道能带参与电导时，载流子浓度很小，有效质量也很小。描述了这一反常现象在不同材料中的表现。
In this paper, the history of the discovery of the linear magnetoresistance in metals by Kapitza from 1928-1929 and its explanation are described. Actually, Kapitza discovered two different phenomena. One of them, the linear magnetoresistance at classically large magnetic fields in polycrystalline samples of metals, having open Fermi surfaces, was explained by Lifshits and Peschansky in 1958. The other phenomenon is the quantum linear magnetoresistance appearing in metals, or semimetals, with a small concentration of carriers and a small effective mass, when only the lowest Landau band participates in the conductivity. Manifestations of this unusual phenomenon in different materials are described.
