This paper presents the statements of the Uniqueness Theorem for magnetic field at first, then proves it in Conlomb Norms and general conditions. The latter is only a special one under the normal case.

本文首先给出静磁场唯一性定理的表述形式，对一般情况下和库仑规范条件▽A=0下的情况均作了证明，得出后者只是一般情况下的一个特例。

It is a usual presumption that distribution function can decide characteristic function and characteristic function can also decide the distribution function by the uniqueness theorem.

但通过本文引入的反例，我们可以知道，唯一性定理在有限区间上不成立，不过在无穷限区间上我们仍可以说，分布函数和特征函数是一一对应的。

Taylor expansion gives proof to the uniqueness theorem and the maximum modules principle , which is simple and clear at a glance, compared with the traditional proo

利用泰勒展开式证明了唯一性定理，最大模定理，与传统证明相比，具有简单、一目了然的特点。

The limits of non－ degenerate quasilinear equations (i.e. the regularizing problems) are established. The uniqueness theorem is proved by the contraction property of the solution.

通过对非退化拟线性抛物型方程系列解的极限研究，给出问题的存在性证明，对解的唯一性证明，用解的压缩性质。

For instance, we obtained the existence and uniqueness theorem and several judgement theorems on stability and instability for several types of nonlinear singular systems. Using Z-transformation, we estabilished the response formula of discrete singular systems with delay, and obtained the sufficient and necessary condition of rearchability.

如我们得到了某些非线性广义系统解的存在唯一性定理，及稳定与渐近稳定的判据；利用Z变换方法，得到了滞后离散广义系统的一般响应公式，进而得到了局部可达与局部能控的充要条件等。
