This theory has three constants, i.e. speed of light c, de Sitter radius R and Planck length lp. 这个理论有三个不变常数,光速c,德西特半径R和普朗克长度(PL)lp。
If the scalar to be quantum mechanically stabilized with a most probable radius of the planck length. 如果把标量场X看作时间变量,则可得到宇宙的最可机半轻为Planck长度,这说明宇宙是量子力学稳定的。
A brief review is presented of three fundamental physical quantities derived by Max Planck in 1912, referred to have as the Planck mass, Planck length and Planck time which had been arranged in the tables of 1986 and 1998 fundamental physical constants. 简要介绍了普朗克于1912年提出的三个基本物理量:普朗克质量、普朗克长度(PL)和普朗克时间.它们已被列入1986和1998年基本物理常数表。

It is shown that under the quantum conformal fluctuation the expectation values of the proper time and the proper length in any space-time are bounded at Planck time t_p and Planck Length(PL) l_prespectively. 在这种量子共形起伏下,任何时空的本征时间和本征长度的最小极限分别为普朗克时间t,和普朗克长度(PL)1p。
