To improve library network security , we should Cret draft network security management strategies , construct multi-level protection systems , and then put emphasis on daily security management .

图书馆加强网络安全，首先要制定网络安全管理策略，并构建整体性的多层防护体系（安装防火墙，部署入侵检测系统，安装防毒墙等），要加强日常安全管理。

Chemiluminescence resonance energy transfer ( CRET ) involves nonradiative energy transfer from a chemiluminescence ( CL ) donor to a suitable acceptor molecule .

化学发光共振能量转移是将能量由化学发光反应的供体分子传递给合适的能量受体分子。

The fluorescence spectrum of the Luminol-H2O2-HRP-F system at its free state and bound state were discussed , respectively . This thesis also studied the mechanism of the Luminol-H2O2-HRP-F CRET system .

分别讨论了Luminol-H2O2-HRP-荧光素化学发光共振能量转移体系在游离状态和绑定状态下的荧光光谱性质，并对其反应机理进行了研究。

This thesis studied the luminol-H2O2-horseradish peroxide ( HRP ) - fluorescein ( F ) chemiluminescence resonance energy transfer ( CRET ) system . Based on this CRET system , an aptamer-biosenser was established , achieving a high sensitivity detection of thrombin .

本文对Luminol-H2O2-辣根过氧化物酶（HRP）-荧光素（F）化学发光共振能量转移体系的反应机理进行了研究，基于该体系建立了适体生物传感器，实现了对凝血酶的高灵敏度检测。
