Reflection filters have various applications in optical communication and other systems.In this letter,we propose a narrowband high-reflection filter composed of dielectric and metallic layers,in which an optimized filter combined with an admittance-matching layer with broad stop band is achieved.The structure can be expressed as Sub | (HL)13H2L(HL)313Cr0.84H | air,with full-width at half-maximum (FWHM) bandwidth of 2.5 nm.Based on this structure,reflection filters with multi-peaks are presented,and the law of distribution of peak positions is drawn.

《说文解字》:“史,记事者也。从又持中。中,正也。”即认为“史”的字形上部是“中”字,下部是一只手,以手持“中”字,说明史官记史应该持中正态度,也就是说,许慎是从史官记录历史态度的角度去解释“史”字形体的。这一观点影响深远,大概因甲骨卜辞中有“立中”的说法,如“己亥卜,争贞,王勿立中。
