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.
