Based on the optical rotatory dispersion effect,an optical filter for selecting the second harmonic of a frequency-doubled laser is constructed from quartz in combination with polarizers.The operating principle is analyzed by matrix formulation,and the result indicates that the second harmonic of a frequency-doubled laser will be obtained when the rotation angle has a difference of(2n+1)π/2 (n=0,1,2,3,...)between the two polarizations of the second-harmonic laser and the fundamental laser.The spectrum of the output laser is taken by the AQ-6315A spectrometer,and the experimental results are in good agreement with the theoretical results.

12月18日，“2013年《社会蓝皮书》发布暨中国社会形势报告会”在北京举行。蓝皮书指出，收入分配改革必须改变和改善社会收入分配结构，否则简单的收入翻番也不能叫做收入分配改革。 “应加快调节收入和利益分配结构步伐，但是也应该注重顶层设计”。该书主编之一，中国社科院荣誉学部委员、中国社会学会荣誉会长陆学艺对《中国新闻周刊》说。 《中国新闻周刊》从相关渠道获悉，原计划在12月底出台的《收入分配体制
