查询词典 gravitation

No other comparably fertile period for individual scientific accomplishment can be found except during 1665 and 1666, the original annus mirabilis, when Isaac Newton, confined to his country home to escape the plague, started to lay the basis for the calculus, his law of gravitation and his theory of colors.

除1665至1666年，Issac Newton为了躲避瘟疫将自己禁闭在乡下的家中开始构思微积分，引力定律，和光学理论这光辉的一年，历史上还没有任何一个时期个人取得的科学成果可以与其相提并论的。

In this paper the writer employs complex Riemannian Geometry and defines the absolute interval between two points as consisting of a real part and an imaginary part. Two postulates and are used: the first may be called law of gravitation and electro-magnetism; the second equation of motion.

在此文内，作者利用复变来曼几何以宇宙间两点之距离为一实数及一虚数部分相构而成，於此并用假说：一可称为吸力及电磁定律，一为物体行动定律，解释吸力及电磁力之各种现象。

First, we deduce a formula for vacuum polarization pressure as f ＝ G m M （ r ∕ r ＋ v ∕ c ）∕ r 2 , based on the isotropy of distribution of neutrinos ν0 in the lowest energy state in the physical vacuum, requested by the Pauli exclusion principle. Then, we deduced the metric equation of the general relativity and the equivalence principle according to this formula. Further, we demonstrate that this vacuum polarization pressure is the gravitation in general meaning.

首先从泡利不相容原理要求的在物理真空中最低能态中微子ν0分布的均匀各向同性出发，推导出真空极化压力公式 f ＝ G m M （ r ∕ r ＋ v ∕ c ）∕ r 2 ，然后由此公式推导出广义相对论的度规方程和等效原理，并论证此弱作用力的真空极化压力就是通常意义下的引力。
