low indicator meaning in Chinese

低指示器

The preparation of optically active composite is a promising alternative to obtain a kind of new and competitive sensing membrane for fiber optic sensors , and has attracted the global attention . in this thesis , the modified sol - gel sensing membranes based on fluorescence quenching have been prepared by using tetraethoxysilane ( teos ) and dimthyldimethoxysilane ( dds ) as the main material , formamide as the drying control chemical additive ( dcca ) , ru ( phen ) 3cl2 and ru ( bpy ) 3cl2 as the indicator . this kind of membranes is crack - free and has low indicator - leaking rate
本文以四乙氧基硅烷( teos ) 、二甲基二乙氧基硅烷( dds )为主要原料，以甲酰胺为控制干燥剂，二价钌离子络合物钌( ) ?联吡啶( ru ( bpy ) _ 3cl _ 2 )和钌( ) ?菲咯啉( ru ( phen ) _ 3cl _ 2 )为荧光指示剂，采用改进的溶胶凝胶技术，通过添加控制干燥剂和有机掺杂两种手段，制备了基于荧光猝灭原理的光纤氧敏感膜。
