square millimeter

The square of an odd prime is an anti-sociable number;

奇素数的平方都是孤立数

In this paper,with the Baker method,we prove that if p>C,then a-bs_p is never a square,where C is an affectively computable constant depending only on a and b.

本文运用 Baker 方法证明了:当 p>C时,a-bs_p 都不是平方数,这里 C 是仅与 a,b 有关的可计算常数。

The thermodynamical properties of the two dimensional square lattice and the three dimensional simple cubic lattice transverse Ising model with spin - 1/2 are investigated within the framework of the finite cluster appraximation.

本文在有限集团近似的框架内研究了自旋为1/2的二维平方晶格和三维简立方晶格横场伊辛模型的热力学性质,得到了相应的相图,临界温度和临界横场。
