一九八六年第十二期答案 1.答:在描述物理定律和探头物理量之间的联系时,经常会涉及一些不随时间和环境条件而变化的普适常数,人们称它们为基本物理常数或基本常数。目前国际上推荐了(在基本常数表中列出)37个有独立符号的基本常数。它们包括:引力常数G、阿伏伽德罗常数e_0、真空中光速c、法拉第常数F、玻耳兹曼常数K等宏观基本常数,以及普朗克常数h、电子电荷e、电子质量m_e、电子轨道半径a_0、精细结构常数a、玻尔磁子μ_B、水中质子回旋磁比γ_p、电子康普顿波长λ_e等微观基本常数,此 Answers to the Twelfth Issue, 1986 1. A: In describing the connection between physical laws and physical quantities of the probe, there are often some ubiquitous constants that do not vary with time and environmental conditions, and are referred to as basic physical constants Or basic constant. It is internationally recommended (listed in the basic constant table) 37 basic constants with independent symbols. They include macroscopic fundamental constants such as gravitational constant G, Avogadro’s constant e_0, vacuum speed of light c, Faraday’s constant F, Boltzmann’s constant K, etc., and Planck’s constant h, electron charge e, electron mass m_e, Electron orbital radius a_0, fine structure constant a, Bohr magnet μ_B, Proton gyromagnetic ratio γ_p, Electron Compton wavelength λ_e and other microscopic basic constants, which
