bare core meaning in English

露芯
裸堆芯
无反射层堆芯

Derived from optical waveguide fundamentals , outstanding advantages of mfld in high s / n ratio and sensitivity were theoretically presented . to resolve inconsistent change tendencies of mode - filtered light obtained in bare core sensing system and in modified sensing system , that is , the mode - filtered light signal declines with the increase in analyte ris in bare core sensing system but increases with the increase in analyte ris in modified sensing system , we started with light energy radiation theory , and obtained the details of mfld mechanism by discussing in detail the radiant energy ' s reflection and refraction at the interface , thus establishing a mathematical model of mfld . we concluded that the inconsistent change tendencies of mode - filtered light were essentially coherent
为了解决实验中裸光纤体系与修饰光纤体系在获取模式滤光信号上出现的不一致现象，即裸光纤体系中随着分析对象的折射率增大，获取的模式滤光信号呈下降趋势，而在修饰光纤体系中分析对象的折射率增大，获取的模式滤光信号却是增大的，我们从光的能量辐射学入手，详细地讨论了光辐射能在传输路径上的反射与透射，获得了模式滤光信号产生的细节，以此建立了模式滤光检测的新模式。
