1)  charge and flux conservation
电荷和磁通守恒
2)  charge conservation
电荷守恒
1.
In circuit analysis,charge conservation and flux conservation road are often used for instantaneous capacitor voltage and inductor current mutation,which are called the state analysis because it only has the moment of 0-and 0+.
在电路分析中,电荷守恒和磁链守恒常被用于换路瞬间电容电压和电感电流的突变问题,因为只涉及0-与0+两个时刻,可称之为状态分析,实际上反映的是系统电荷或磁链的连续性问题。

全磁通守恒(fluxoidconservation)

一个多连通超导体内每一个孔的冻结磁通是量子化的。为简单起见考虑只有一个孔。设环绕该孔的闭合曲线为C,由GL理论可得:

`\phi_L=\oint_C[bb{A}(bb{r}) \frac{m}{2e^2|\psi(bb{r})|^2}*bb{j}_s(bb{r})]*dbb{l}`(1)

式中φL为孔所冻结的全磁通,A(r)为矢势,m和e为电子质量与电荷,js(r)是超电流密度,而GL序参量|ψ(r)|2=ns为超导电子对数密度,$\psi(bb{r})=|\psi(bb{r})|e^{i\varphi(bb{r})}$为复量。由GL电流方程可将上式化为:

$\phi_L=\frac{\hbar}{2e}\oint_C\nabla\phi(bb{r})*dbb{l}$

$=\frac{\hbar}{2e}[\phi(bb{r}_p)]$

P为C上任意选定的点,[φ(rp)]表示从rp出发环绕C一周又回到rp后φ(rp)数值的改变。由于ψ(r)是r的单值函数,故[φ(rp)]=2πn,n为整数。于是

φL=nφ0(2)

φ0=h/2e=2.07×10-15韦伯为磁通量子,因此全磁通是量子化的。由于nφ0是常数,则φL不随时间变化,是守恒的,称全磁通守恒。例如初始时刻孔的磁通ΦL=0或nφ0(n≠0),则由式(1)和(2),没有附加条件,则不论外加或撤去磁场,或有电流js,以后仍保持孔的磁通ΦL=0或nφ0(n≠0),保持守恒。
