Dehydroascorbate reductase catalyzes the re-reduction of DHA to ascorbate by glutathione. Thus, dehydroascorbate reductase is critical for protection of cellular components against oxidative injury.

脱氢抗坏血酸还原酶以谷胱甘肽为底物，催化脱氢抗坏血酸还原为抗坏血酸，在循环利用抗坏血酸、保护细胞组分抵御氧化损伤中发挥重要的作用。

Thepressurized and well-mixed hydrogen/air mixture is rapidly ignitedthrough the spark because hydrogen has a fast flame front.

加压，并充分混合的氢/空气混合物是通过迅速点燃星火，因为氢有一个快速火焰面。

Products include: aluminum hydroxide, magnesium hydroxide, white carbon black, bentonite, extinction powder, muscovite, sericite, talc, GCC, light calcium, clay, water-washed kaolin, alumina, titanium dioxide, such as modified more than 26 kinds of products.

There are two important mechanisms for increasing laser power afteradding hydrogen:(1)The gas temperature and CuBr vapor density at the center of lasertube are reduced, it decreases collision energy depletion of electron and leads to increaseelectron temprature;(2)Electron density increases during the pulse, the skin effect andthe" black center" of laser are improved.

同时，脉冲期间的电子密度增加，电子密度的趋肤效应减弱，激光的&黑心&现象被改善。2存在一个最佳充氢范围，其原因是：充氢后，随着气体温度的进一步降低，电子温度和铜原子数密度也将下降，它们与使电子温度升高的因素相互制约，抑制了激光能级粒子数的增长。

Every living organism consisted of hydrogen in its constituents. Petroleum, natural gas and town gas also composed of hydrogen.

一切生物的细胞组织成份里都含有氢，石油、天然气和煤里也含有氢。

Using the time-match semiempirical models for two flares (one is classified as a SB flare and the other a 2B flare), which were deduced from the spectral data obtained with the solar tower telescope of Nanjing University, we calculate the radiative loss at different phase of the flares.

针对我们已经建立的二个定态色球耀斑半经验模型，计算了耀斑不同时刻下的色球辐射损失速率，包括氢在四个能级假设下的所有跃迁、CaⅡ在五个能级下的所有跃迁、MgⅡ在三个能级下的所有跃迁、以及负氢离子的自由——自由和束缚——自由跃迁等。
