脉冲周期 IPP
repetition interval
impulse period
recurrence interval
- 就是说当脉冲周期小于某一临界值时,存在全局稳定害虫灭绝周期解。
When the impulsive periodic increase, the trivial periodic pest-eradication solution loses its stability and a positive periodic solution comes out. - 本设备采用电子控制喷吹系统,任意调节脉冲周期和宽度,操作灵活方便。
The equipment adopts electronic control spraying and blowing system and can adjust pulse cycle and width freely. Its operation is flexible and convenient. - 介绍了与之有关的两个模型:(1)高速中子里的中微子火箭喷流模型;(2)脉冲星周期突变的3P2中子超流涡旋涡旋相振荡模型。
Two relevant models are intro-duced: (1) The neutrino rocket model for neutron stars with high velocities; (2) The 3P2-superfluid phase transi-tion model for pulsar glitches.
