19世纪后半期和20世纪初,人们发现一系列用经典物理理论无法解释的现象,如黑体辐射规律、光电效应、原子的核式结构、康普频效应等等。这些现象迫使一些科学家放弃原来的经典理论,提出所谓“量子”概念。对“量子”现象不断的深入研究,导致1925年形成一门新的物理学分支——量子力学。从一些国家发行 In the second half of the 19th century and the beginning of the 20th century, people found a series of phenomena that can not be explained by the classical physics theory, such as the law of blackbody radiation, the photoelectric effect, the atomic nuclear structure, the Common frequency effect and so on. These phenomena force some scientists to abandon the original classical theory and propose the so-called “quantum” concept. Continued in-depth study of the phenomenon of “quantum” led to the formation in 1925 of a new branch of physics - quantum mechanics. Issued from some countries
