为分析电流型全桥软开关逆变器中出现的频率跃变现象,针对软开关电路的高维、自治特性,提出了一种基于半解析半数值方法的广义离散映射模型,并基于Floquet理论给出依据该离散映射模型的系统局部稳定性判定方法。
After switching, the original state of circuit capacity voltage or circuit inductance current hasn t the jump normally, but sometimes there can be the jump.
在电路换路后,其电容电压或电感电流的初始状态一般不产生跃变,但有时也可能产生跃变,当一时难于确定时,可先将电路化为其s域模型,并将0-值带进换路后的电路模型,再应用拉氏变换的初值定理,即可在s域解决t域响应的初始状态0+值的问题。
The results indicate that annual temperature has three relatively big jumps in recent one hundred years which happens in 1920, 1955 and 1978 respectively.
指出 :①我国气温有 3次全国性的跃变 ,分别在 192 0、195 5和 1978年 ,每个阶段平均持续期为 30年 ,这和北半球气温跃变点是基本一致的 ;②我国气温从 1978年开始进入了一个稳定增温的气候阶段 ,直到目前全国年平均气温比上一气候阶段增加了 0 。
The jump was defined as the level that the preceding numbers of R data could not completely describe the present value.
与统计概念不同，文中的跃变定义为前Ｒ个数据不能完全表达当前时刻值的程度。
In the cutset of capacitive branch in which voltage s leaping is possible, if there is no impulse current in those branches except for capacitive ones, capacitive charge is conservational, otherwise it may be not conservational.
