compared with typical programming models in unity

UNITY是一种简单统一的理论、计算模型和证明系统,而且具有很强的把UNITY程序映射成不同的计算机体系结构模式的能力.该文在简述UNITY机理的基础上,分析UNITY与几种典型的程序设计模型(函数式、命令式、逻辑式、基于规则式、Petri网、CSP)的区别,并给出它们对应的等价UNITY程序转换,最后,介绍Seuss对完善UNITY的新策略

Electrosynthesis of A New Electroactive Poly(2,2'-Diaminophenyloxydisulfide)

在Pt电极上 ,LiClO4 和不同酸的乙腈 /四氢呋喃溶液中 ,通过动电位连续扫描法合成了新型电活性聚 (2 ,2’ -二氨基苯氧基二硫化物 ) (PDAPD) ,研究了电解质LiClO4 及不同酸 (HCl、CF3COOH、CCl3COOH、CH3COOH)的浓度对合成产物的影响 ,实验结果表明 :浓度为 0 .1mol/L的LiClO4 及浓度在 0 .0 5～ 0 .5mol/L之间的HCl是获得高电活性的聚合物导电膜的最佳实验条件A new electroactive poly(2,2' diaminophenyloxydisulfide) (PDAPD) was successfully synthesized from acetonitrile(AN)/tetrahydrofuran(THF)solutions containing the supporting electrolyte(LiClO 4)and the various kinds of acids(HCl,CF 3COOH,CCl 3COOH) on Pt electrode by consecutive cyclic voltammiry. The effects of the concentrations of supporting electrolyte(LiClO 4) and acid(HCl,CF 3COOH,CCl 3COOH) on electrodepositon of PDAPD film were investigated. The best experimental conditions for electrosynthesis of a highly electroactive conducting polymer film are that the concentrations are 0.1 mol/L and between 0.05 mol/L～0.5 mol/L,respectively for LiClO 4 and HCl.作者联系地址：广州大学化学系,广州大学化学系,广州大学化学系,广州大学化学系,广州大学化学系,华南理工大学高聚物结构与改性研究室,华南理工大学高聚物结构与改性研究室 广东广州510405 ,广东广州510405 ,广东广州510405 ,广东广州510405 ,广东广州510405 ,广东广州510641 ,广东广州Author's Address: 1.Dept. of Chem., Guangzhou Univ., Guangzhou,510405 China; 2.
