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.
动态电路换路时 ,若存在由纯电容和理想电压源构成的回路 ,则电容电压就有可能跃变 ,在含电压可能跃变的电容支路的割集中 ,若除电容支路外的支路中无冲激电流存在 ,则电容电荷守恒 ,否则电容电荷有可能不守恒 ;若存在由纯电感和理想电流源构成的割集 ,则电感电流就有可能跃变 ,在含电流可能跃变的电感支路的回路中 ,若除电感支路外的支路中无冲激电压存在 ,则电感磁链守恒 ,否则电感磁链有可能不守恒。

The law that the voltage on a capacitance and the current in a inductance can t leap is deduced in the case that the voltage and the current are finite.
电容电压与电感电流不能跃变的换路定率,是在电容电流与电感电压为有限值情况下推导出来的。
In this paper, the reconstruction of 6 regional dry /wet grade series with one--year resolution for the last 1 033 years in East China and the variation feature of them, such as periodicity and abrupt change, are presented.
本文利用我国的历史气候记载,为东部6区域重建了最近1033年的时间分辨率为1年的区域于湿气候序列,讨论其可靠性,并分析其变化的准周期性和跃变特征。
With the help of a 10a slipping window,we find that those 10a global had an abrupt change between 1981—1987a,and so did Area Ⅰ and Ⅱ.
5°N)是值得重点关注的两个区域,二者之间存在较强的负相关;取长度为10a滑动窗口研究-Cglobal随时间的演变特征发现,C-global在1981—1987a之间发生了明显的跃变,并且这一跃变可能是年代际尺度上的行为;区域Ⅰ和Ⅱ对这一跃变也有清晰的反映,区域Ⅱ的跃变略滞后于区域Ⅰ;与此同时北太平洋海域关联系数的最小值点随时间演变还出现了明显的"位移"。
