1) population declining mechanism
种群递减机制
1.
To resolve the problem,a novel algorithm called Population Declining-Mutation Ant Colony Optimization(PDMACO) is proposed by introducing population declining mechanism and mutation mechanism of Genetic Algorithms(GA) to ACO.
蚁群算法(ACO)解决组合优化问题有着优良的性能,但由于信息素的不断积累,容易陷入早熟收敛,不能得到全局最优解,为了克服这个缺点,把种群递减机制和遗传算法中的变异机制引入ACO,提出了种群递减-变异蚁群算法(PDMACO),然后将PD-MACO应用到多用户检测中;仿真结果证明,PDMACO多用户检测器在抗多址干扰和远近效应能力方面远优于ACO多用户检测器,并接近于最优多用户检测器。
2) Population reduce
种群衰减
3) population depression
种群减退
4) Dispersalmechanism
种群行为机制
5) population control
种群控制

This study covers the contact toxicity,repellence activity and population inhibition of green prickly ash essential oil,red prickly ash essential oil,1st grade spicy element and 2nd grade spicy element against Tribolium castaneum adults at 30 ℃.
在30℃的恒温条件下,研究了青椒精油、红椒精油、一级麻素和二级麻素这4种花椒提取物对赤拟谷盗成虫的触杀、驱避及种群抑制作用,结果表明二级麻素和青椒精油的触杀效果较好,红椒精油的效果最差;两种花椒麻素对赤拟谷盗都表现出较好的驱避效果,且随着浓度的提高而增强,随着时间的延长而降低;花椒精油及麻素对赤拟谷盗的种群抑制作用随着药剂浓度的增大而增强,其中一级麻素的抑制效果最好,两种花椒精油的抑制效果较差。
