In order to get the information of interaction between metal complex and DNA and select metal complexes which can cleave DNA effectively, twenty seven transition metal complexes containing O/N coordinate atoms have been synthesized in this thesis. We report the synthesis, crystal structure and properties of the complexes. One of the complexes is the first μ〓-oxalato tetranuclear Cu complex, in which there is ferromagnetic interaction between the copper atoms bridged by oxalate ions. Two trinuclear copper complexes containing partial cubane Cu〓O〓 cores have been synthesized and discussed the magnetic properties.

However, as shown by computation, the products are thermodynamically controlled, and the S—O cleavage is predominates over the C—O cleavage.

理论计算表明，最终反应的产物是受热力学控制的， S—O键的断裂绝对地优于C—O的断裂。

Diethylthiophosphoryl chloride was synthesized by reacting phosphorus thiochloride with anhydrous alcohol in the presence of NaOH, and then a novel phosphorus-nitrogen- and sulfur-containing flame retardant, 1, 4-di(O,O-diethyl thiophosphoryl imine) benzene, was synthesized via the reaction of diethylthiophosphoryl chloride with p-phenylenediamine.

以三氯硫磷与无水乙醇在NaOH存在下合成了二乙基硫代磷酰氯，然后再与对苯二胺反应合成了新型的含磷、氮、硫的膨胀型阻燃剂：1，4-二（O，O-二乙基硫代磷酰亚胺基）苯。

The second time occurred in June, 1999 which was caused by Pan-Asia topotype serotype O FMDV (O/Taiwan/99). The virus was firstly isolated from Chinese yellow cattle in Kinmen and could infect goats and pigs.

第二次发生在1999年6月，是由泛亚洲O血清型口蹄疫病毒(O/Taiwan/99)所造成，该株病毒最早是从金门的黄牛所分离到，该株病毒除了感染牛只之外，也会造成羊只及猪只的感染。

Triatomic molecules We studied the interaction of linear triatomic molecules CO〓 and CS〓 with the intense femtosecond laser field at different intensities and polarization states. The kinetic energy of the C ion is much less than that of the O ion at the same charge states indicating that the Coulomb explosion is a concerted process, that is, the two C=O broke simultaneously.
