以五硫化二磷、对甲苯酚与三乙醇胺为主要原料,以甲醇为溶剂,成功合成了O,O\'-二(对甲苯基)二硫代磷酸三乙醇铵盐(TADPD).采用动电位极化曲线和失重法评价了TADPD作为新型缓蚀剂在H2SO4溶液中对Q235钢的缓蚀性能.缓蚀性能评价结果表明TADPD是一种混合型缓蚀剂,最高缓蚀率可达99.05％,该缓蚀剂在Q235钢表面的吸附符合Langmuir吸附等温模型;研究缓蚀性能影响因素发现,随着缓蚀剂TADPD浓度增加缓蚀率升高,随腐蚀体系温度升高和H2SO4浓度增大缓蚀率均下降,静置时间对缓蚀效果

在剖析参数对粒子群算法效率和寻优能力影响的基础上,提出了动态自适应时变参数优化的粒子群算法,根据迭代过程对算法中的惯性权重、加速因子进行对应的非线性自适应调整,同时引入动态自适应的控制因子避免寻优过程中粒子因速度远离全局最优位置,并将运用变参优化的粒子群算法应用于三维和多维函数寻优.实验结果表明:动态自适应变参优化的粒子群算法比标准粒子群算法有更好的算法效率和寻优能力,同时在解决多维优化问题上亦具有出色表现.运用结果证明基于动态自适应时变参数优化的粒子群算法较普通的粒子群算法更有优越性.
