Describes the occurrence of two local electric network oscillation accidents, analyses the causes for the oscillations and suggests corrective actions for the problems identified. 描述两起局部电网振荡事故过程,分析产生振荡的原因及暴露的问题,并提出了改进措施。
4, With a two-band tight-binding model drivened by dc-ac electric fields, we investigate the transport characteristics of Rabi oscillations between Bloch bands. 在双带紧束缚模型的框架下,讨论Bloch带之间Rabi振荡的输运性质。
