中文摘要：

在这份报纸，光细菌能被紫外光打死，生物体之发光紧张将被减少，这被发现。与 nanooxide 的保护，生物体之发光的减少能是 supressed，因此光的细菌能被利用分析并且评估 nanooxide 的紫外防护的性质。Vibrio-qinghaiensis Q67，一种光细菌，这里被使用在细菌的光紧张上学习不同类型的影响和 nanooxide 的集中，它被 UVA， UVB 或 UVC 光分别地照亮。一个方法根据光紧张的减少的相对价值被建立，它能被用来分别地对 UVA， UVB 或 UVC 光分析并且评估 nanooxide 的紫外防护的性质。为化妆品和另外的工业分析并且评估 sunscreen 的紫外防护的性质也提供了一个有效方法。

英文摘要：

In this paper, it was found that luminescent bacteria could be killed by UV light and the bioluminescence intensity would be decreased. With the protection of nanooxide, the decrease of the bioluminescence could be supressed, therefore luminescent bacteria could be utilized to analyze and evaluate the UV-shielding property of nanooxide. Vibrio-qinghaiensis Q67, a kind of luminescent bacteria, was used here to study the influence of different kinds and concentrations of nanooxide on the luminescence intensity of bacteria, which were illuminated by UVA, UVB or UVC light, respectively. A method was established according to the relative value of the decrease of the luminescence intensity, which can be used to analyze and evaluate the UV-shielding property of nanooxide against UVA, UVB or UVC light, respectively. It also provided an effective way to analyze and evaluate the UV-shielding property of sunscreen for cosmetic and other industries.
