Methods The basic governing equations of quasicrystal elasticity theory and Gauss's theorem were applied in the derivation. 目的推广经典晶体弹性理论中的几个基本定理到准晶弹性理论中去。
Coulomb's law and Biot-Savart's law are two basic electromagnetic laws while Gauss 'theorem and Ampere's theorem are more practical and convenient in applications. 在电磁学中,库仑定律和比奥&萨伐尔定律是基本定律,而高斯定理和安培环路定理实用性更强,应用更方便。
The latter is concluded by Gauss's famous Fundamental Theorem of Algebra. 后者以高斯的代数方程的基本定理作为结束。
Furthermore, some equations and theorems such as Gauss's theorem are put forward. 应用上述充要条件可以导出其它公式及定理,如高斯定理等。
