4.1.2塞曼效应 896年，塞曼在研究磁场对光的影响实验时发现 One of the items in the Zeeman archive is a laboratory notebook that contains the first recorded observation of the Zeeman effect [8].The entry is dated 2 September 1896 and is preceded by many pages of notes on totally unrelated experimental work.It opens with the words: 'Influence of magnetization on flame.'The notes that follow describe a very simple experiment:a piece of asbestos,soaked in a solution of kitchen salt,is put in a flame placed between the poles of a magnet.With the help of a grating,a spectrum is created.The vellow sodium D-lines appear as narrow and sharp lines.'When the magnet is switched on',the description continues, the lines become wider until they are two to three times 塞曼(P.Zeeman, as wide'.This simple sentence describes the discovery 1865-1943),荷兰 something new. A publication describing his 人，1902年诺贝尔 experiments was presented by Kamerlingh Onnes at the 物理学奖获得者 monthly meeting of Saturday 31 October of the Section "in recognition of the of Sciences of the Dutch Academy of Sciences.In it Zeeman concluded: extraordinary service they rendered by their researches The experiments have made it increasingly probable that into the influence of magnetism absorption and thus also emission lines of a gaseous upon radiation phenomena" substance are widened by magnetic forces.[4] A.J.Kox,Euro.J.Phys.18(1997)139-1444.1.2 塞曼效应 塞曼（P.
