紫外辐射

It developed for military affairs first in Occident .It utilizes the characteristic of NUV spectrum (240-280nm) that UV spectrum of object is much greater than that of solar radialization in the aerosphere. Double spectrums imaging system gets UV and visible images to identify the object and background. Image infusion is a essential step of succedent image processing.

它利用中紫外区的"日盲"(240—280nm的中紫外)特性，即目标发出的紫外线远远强于太阳的紫外辐射，通过双光谱图像检测系统观察和检测该波段的紫外目标信号与背景可见光图像，并利用图像配准与融合技术，把紫外光图像准确地定位于背景图像，形成合成图像达到检测目的。

To understand whether the GST can protect plant from the damage of ultra-violet radiation,a UV inducible GST gene was isolated from an Arabidopsis cDNA library.The plant expression vector containing the GST cDNA was constructed and transferred into Arabidopsis thaliana plants by the Agrobacterium-mediated vacuum method.Molecular genetic analyses showed that the overexpression of the UV inducible GST could increase the tolerance of the transgenic plants to UV radiation

为了阐明GST在紫外辐射下是否对植物有保护作用，以紫外强烈诱导表达的GST cDNA为探针，筛选拟南芥cDNA文库，获得了这种GST的全长cDNA；利用此cDNA构建植物表达载体，并通过农杆菌介导法转化拟南芥，使其在拟南芥中得到大量表达；通过对转基因植株的紫外辐射耐性分析，证实了该GST的过量表达可明显增强拟南芥对紫外辐射损伤作用的耐受性。

Based on the measurement of chromophoric dissolvable organic matter in 22 shallow lakes in the middle and lower reaches of Yangtze River, the attenuation of ultraviolet radiation in the lakes in the middle and lower reaches of Yangtze River and corresponding penetrating depth were estimated using empirical models; and checked up utilizing the field measured attenuation of ultraviolet radiation in Lake Donghu Wuhan.

基于对长江中下游22个浅水湖泊有色可溶性有机物吸收的测量，运用经验模式估算了紫外辐射在长江中下游湖泊的衰减及对应的穿透深度，并利用在武汉东湖实测的紫外辐射衰减进行了检验。

Although ultraviolet-absorbing compounds were induced by solar ultraviolet radiation, they could not fully counteract the damage to H. fusiformis induced by UVR.

此外，阳光紫外辐射也诱导产生了一定量的紫外吸收物质，但并不足以抵抗紫外辐射对藻体的伤害作用。

Effects of solar ultraviolet radiation on the growth and photosynthesis of the economic brown alga Hizikia fusiformis were investigated while exposed to full spectrum solar radiation (280－700 nm), solar radiation depleted of UV-B (320－700 nm) and solar radiation deprived of total UVR (400－700 nm) in order to understand its responses to changes in solar UVR.

为探讨经济褐藻羊栖菜对阳光紫外辐射变化的响应，我们在全波段阳光辐射(280－700 nm)，去除UV-B辐射(320－700 nm)以及光合有效辐射PAR (400－700 nm)三种辐射条件下对其进行培养，测定了其光合作用与生长的变化。

Furthermore, the mixture of \%Cordyceps sinensis\% extract and lysogenic bacteria was irradiated with UV. The results demonstrate that the new methods are practical and easy to conduct, and that \%Cordyceps sinensis\% has a strong protection effect

本研究还将冬虫夏草浸出汁与溶源菌混合后进行紫外辐射，通过几种方法进行比较，结果证明建立的新方法确实可行，易操作；同时也表明冬虫夏草具有较强的抗紫外辐射作用
