Methods Mice were treated with three different doses of extract of ginger:high dose (9.3 mL·kg-1), middle dose (4.7 mL·kg-1),and low dose (2.3 mL·kg-1). All mice were irradiated once with 2.0 Gy X-ray. At the same time, the negative group (treated with vegetable oil only) and positive one (irradiated as well as extract of ginger groups after treated with vegetable oil) were set up. The changes of activities of enzymes in testes of mice were observed.

AtDFA is dihydrofolate synthase localized in mitochondria, it catalyzes one glutamate added to the dihydropteroate and produces dihydrofolat. AtDFB, AtDFC and AtDFD are folylpolyglutamate synthase localized in plastid, mitochondria and cytosol respectively. A short chain ofγ-linked glutamates can be added by FPGS.Folate molecules exist in vivo mainly as polyglutamates and these are preferred by folate-dependent enzymes.

AtDFA为二氢叶酸合成酶(dihydrofolate synthase，DHFS)，定位于线粒体，在它的催化作用下，一个谷氨酸分子与二氢蝶酸(dihydropteroate ， DHP)相结合，形成二氢叶酸；AtDFB、AtDFC、AtDFD为多聚谷氨酸合成酶(folylpolyglutamate synthase，FPGS)，分别定位于质体、线粒体和细胞质，在多聚谷氨酸合成酶的作用下，谷氨酸分子可以逐一连接到四氢叶酸的谷氨酸γ位。

Applied with test of potted plant and measurement absorbency for study physiological response of activity of cell defense enzymes and lipid peroxidation of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of superoxide dismutase, catalase, antioxidant, malondialdehyde and the rate of superoxide anion(-O2) generating are mensurated under normal water condition while soil water content is 70% and light water stress while soil water content is 55% to 60% and medium water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of contents of SOD,CAT,AsA,MDA are mighty notable difference. The rate of -O2 generating is notable difference within families. The rate of -O2 generating is mighty notable difference within water grades.

为研究湿地松优良半同胞家系保护酶及脂质过氧化作用对水分逆境的生理响应，采用盆栽试验和吸光度测定结合的方法，以普通湿地松种子为对照，测定了七个湿地松半同胞家系在正常水分状态（土壤相对含水量为70%）、弱度水分胁迫（土壤相对含水量为55%~60%）、中度水分胁迫（土壤相对含水量为35%~40%）和强度水分胁迫（土壤相对含水量为20%~25%）条件下的SOD、CAT、AsA、MDA的含量和-O2产生速率，研究结果表明：无论是不同水分梯度还是不同家系水平，SOD、CAT、AsA活性和MDA含量的差异均达极显著水平，不同家系水平间-O2产生速率有显著差异，不同水分梯度间-O2产生速率差异达极显著水平。

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.
