The results indicated that the DNA damage could be accelerated by Fenton reaction in the presence of ascorbic acid but was inhibited slightly by hydroxyl free radical scavenger such as mannitol or dimethyl sulphoxide under the experimental conditions.

试验结果显示，抗坏血酸存在时可以加速Fenton反应对DNA的损伤，而在同样条件下，自由基捕获剂甘露醇或二甲基亚砜对由Fenton反应造成的DNA损伤的抑制作用却不是很大。

The high activity can be attributed to the following factors: 1 Because of the perovskite structure of the host materials, the positive and negative electric charge center is not superposable, and there is a electric field which can separate the photo generated electrons and holes efficiently in the microscopic field.

以层状基质热稳定性分析为依据，经过对制备方法的优化，在不同温度下进行硫化处理，在对催化剂进行产氢性能研究时发现，在以硫化钠和亚硫酸钠为牺牲剂的产氢体系中，插入硫化镉的复合层状催化剂负载一定量铂以后，具有较高的连续的光催化分解水的能力。

The Syrophoenician woman, blind Bartimaeus, and many others had cried to Him for help,"Have mercy on me, O Lord, Thou Son of David."

2AN oxygen radicle benzene Mao water solution reaction process in, the hydrogen bromine is sour with acetic acid Mo Er compare for 1:be tetrahydroxy and 2 mols at 1:00|weigh to crystallize in the L hydrochloric acid aqua, the product accepts to lead superior turn

甲氧基苯醌水解反应过程中，当氢溴酸与醋酸摩尔比为1：1时，四羟基苯醌与2mol/L的盐酸溶液中重结晶产品收率最佳

By O2 equilibrium, gel permission chromatography, and autooxidation analyses, we have investigated that the pos itively charge of b82 Lysyl residue is indeed involved in the exhothermic O2 b inding characteristics and somewhat stabilize the tetrameric heme moiety of Hb A.

其纯度以可见光谱和血色素电泳鉴定，并以氧合平衡曲线的测定，胶质层析和氧化速率的分析检视重组血红蛋白之性能。实验结果显示β82Lysyl残基所带的正电性确实影响血红蛋白氧合时的放热反应与其四合体的安定性。

This product was prepared w ith octamethyl-cyclotetrasiloxane and tetramethyltetravinylcyclote-trasiloxane as monomers,a low visco sity hydroxyl -terminated silicone oil as an end -bl ocking agent and tetramethylammonium hydroxide as catalyst.

以八甲基环四硅氧烷为单体，四甲基四乙烯基环四硅氧烷为改性单体，羟基硅油为封端剂和相对分子质量调节剂，四甲基氢氧化铵为催化剂，在羟基硅油质量分数小于0.13%，催化剂质量分数为0.004%～0.007%时，采用共聚法制备了相对分子质量大于45×104，收率大于90%的端羟基聚二甲基硅氧烷。

A similar reaction of the sulfur analog gave only the product of tetramethylene bridged bisdititanium halides.

在企图合成硫桥环戊二烯基化合物时，得到的却是四亚甲基桥联双环戊二烯基金属衍生物。

The theoretical properties of BTATz were estimated by a B3LYP method based on 6-31G basis set. The stable geometric configuration and bond order were obtained. The vibrational frequencies, IR spectrum and thermodynamics properties under different temperatures were obtained from vibrational analysis, and the relationship between temperature and thermodynamics properties was deducted. Pyrolysis mechanism of BTATz was discussed, and the transition state and activation energy of ring opening reaction of the tetrazole were deducted.

用B3LYP方法，在6-31G基组水平上对其性能进行了计算，得到了其稳定的几何构型和键级；在振动分析的基础上求得体系的振动频率、IR谱及不同温度下的热力学性质，并得到了温度对热力学性能影响的关系式；探讨了其热解机理，推断出四唑环开环时的过渡态和活化能。
