2、高斯定律 (Gauss’s law):磁场 没有所谓的“磁荷”。磁场线都是闭合的。也就是说,不存在这么一个点,使得磁场线从这里想四周射出。用公式表示就是∫Ω∇⋅Bdx=0.∫Ω∇⋅Bdx=0.由于ΩΩ的任意性,我们得到∇⋅B=0.∇⋅B=0. 3、法拉第电磁感应定律(Faraday's law of induction) 变化的...
高斯定律(Gauss' law)表明在闭合曲面内的电荷分布与产生的电场之间的关系。穿越出任意闭合曲面的净电通量等于该闭合曲面内的净电荷除以电容率: \oint_A\vec{E}\cdot d\vec{a}=\frac{Q_{enc}}{\epsilon} 。其中 d\vec{a} 是该点的单位法向量,也就是说我要的是这点的电场强度在垂直方向上的分量。而...
By using the Gauss-Ostrogradski formula and the following equality $$\begin{aligned} \displaystyle D_{\gamma }\left( y^{\nu }{B_{\theta \nu }^{\gamma }} \right) =\frac{\partial y_{\nu }}{\partial \xi ^{\gamma }}{B_{\theta \nu }^{\gamma }}+y^{\nu }D_{\gamma }{...
In this paper,based on the Gauss law,the equation of electric field line of collinear point charge system was obtained by calculating the expression of electric flux passing through a section of a electric field tube.This equation can be extended to the general case of linear charge distribution...
Equation 1.4 describes that the source of an electric field is from the charge density in a given volume, while equation 1.5 denotes that magnetic monopole does not exist. They are collectively known as Gauss’s law. Equation 1.6 or Faraday’s law explains that a time-varying magnetic field ...
Every algebraic equation has at least one real or complex solution. This assertion is the fundamental theorem of algebra, first proved by K. Gauss in 1799. If α is a solution of the equation (*), then the polynomiala0xn+a1xn–1+ ... +anis divisible byx– α. If it is divisible by...

Shock wave data have been used for EOS development at much higher pressures and temperatures than those encountered in static experiments, for example, to thousands of Kelvin temperature and hundreds of gauss Pascals pressure. Researchers have carried out combined studies on the same materials at the...
(Gauss's law) The notation we have used is the following: E, H, D and B denote the electric field (electric field strength), the magnetic field (intensity of the magnetic field), electrical induction (electrical flux density) and magnetic induction (magnetic flux density), respectively. ...
