The favorable regions for DNA cleavage were observed to be pH 3.6-5.6 and pH 9.0-10, suggesting that the species responsible for DNA cleavage are different in different pH regionsOur results do not support a widely accepted conclusion that the copper-bound or free hydroxyl radicals provided by CuZnSOD with its end product hydrogen peroxide lead to release of copper from its host, the Fenton reaction between the free copper and the hydrogen peroxide being responsible for the aberrant copper-mediated oxidation chemistry in CuZnSOD.

目前广泛接受的一个推测机理是CuZnSOD与H_2O_2反应生成羟自由基损伤酶自身导致Cu释放，而释放出的游离Cu进一步与H_2O_2发生Fenton反应导致了异常催化氧化反应的发生。

Flying isn't human dream, material and material are absolutely contact, and stone, contain CaCO3,... By analogy, you say that all matter, they contain more than the matter, small quarks also can find this matter, if the antimatter, like lodestone, then the humanity will use it to fly in the sky, there is the hydrogen plate, sheet metal plates of hydrogen is close to zero and even, quality, less than zero, the density of titanium and not hypothesis, maybe one day will be achieved.

人类飞天并不是梦想，物质与物质间都存在着绝对的联络，人和石头有联系，都含有CaCO3，……以此类推，你可以说到的全部物质都有联系，它们都含有比夸克还小的物质，如果能找出这种物质的反物质，就像吸铁石一样，那么人类一定会利用它飞上天空，还有就是氢板，氢板是类金属板，质量接近于0甚至小于0，密度大于钛，这并不是假说，可能以后的某一天会实现的。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
