A numerical analysis on dual core photonic crystal fiber (DC-PCF) based surface plasmon resonance (SPR) refractive index sensor is presented.The guiding parameters and required sensing performances are examined with finite element method (FEM) based software under MATLAB environment.According to simulation,it is warranted that the proposed refractive index sensor offers the maximum amplitude sensitivity of 554.9 refractive index unit (RIU-1) and 636.5RIU-1 with the maximum wavelength sensitivity of 5800nm/RIU and 11 500nm/RIU,and the sensor resolutions of 1.72× 10-5RIU and 8.7× 10-6RIU,at analyte refractive index (RI) of 1.40 for x-and y-polarized modes,respectively.As the sensing performance in different wavelength ranges is quite high,the proposed sensor can be used in simultaneous detection for different wavelength ranges.Therefore,the proposed device is of a suitable platform for detecting biological,chemical,biochemical,and organic chemical analytes.

日常饮食中锌、铁等必须微量营养元素长期缺乏会带来严重的健康问题,通过生物强化途径提高主要粮食作物可食部分锌、铁等微量元素的含量,进而改善人体对其日常摄入量,是解决全球性隐性饥饿的有效途径。因此,开展富锌、铁等微量元素作物新品种的选育具有重要意义。为了解析作物子粒锌、铁含量的遗传机制,本研究首先对三种主要粮食作物—玉米、水稻及小麦中现已公布的子粒锌、铁含量相关QTL进行了Meta分析,以对现有数据进
