此外，自然的法则，如重力，逆平方定律，因果关系，以及热力学意味着必有法则的赋予者。
Furthermore, Natural Laws such as Gravity, Inverse Squares, Cause and Effect, and Thermodynamics imply a Law-giver.
重力和其它基本作用力如电磁力之间的关系，是物理学长期以来最引人关注的奥秘之一。
One of the longest outstanding mysteries in physics is how gravity is related to the other fundamental forces, such as electromagnetism.
适用于保守力，像重力和弹力，对非保守力同样，适用，如摩擦力。
This always applies both for conservative forces, like gravitational and spring forces, but it also holds for nonconservative forces such as friction.
但是天文学家们最终发现如行星这样的大天体间的相互作用方式与地球重力并不相同。
But astronomers eventually saw discrepancies in the way larger objects such as planets interacted.
重力设置是令人难以置信的——而泡沫和纸板似乎是失重的，中心舞台的混凝土袋看起来重如它们原有的60磅一样。
The play on gravity is mind-boggling – while foam and cardboard appear as weightless as their original counterparts, the concrete bags at center stage look every bit as heavy as their 60 lb originals.
这项特色是很受人欢迎的，因为它精确地吻合所有已知基本作用力载体（如传播电磁力的光子以及重力的重力子）的性质。
This feature is very welcome because it precisely matches the properties of the carriers of all known fundamental forces, such as the photon (for electromagnetism) and the graviton (for gravity).
本文将重力机制下形成的地层及其适度扩展物(如沉积变质和沉积火山岩类)称之为史密斯地层。
Smith strata are regarded as the strata deposited in gravity, including related strata such as depositional metamorphic and volcanic rocks in this paper.
只有在极端的情况下，牛顿动力学的这两项修正才需上场，如极高的速率（ 狭义相对论）或极强的重力（广义相对论）。
The two proven extensions of Newtonian dynamics come into play under extreme conditions, such as extreme speeds (special relativity) or extremely strong gravity (general relativity).
指具有一定地球物理效应的区域或空间。如地球内外存在的重力场、地磁场、地电场、地热场、地应力场等。
Geophysical field - Domains or Spaces contain certain geophysical effect, such as gravitational field, geomagnetic field, geothermal field etc.
一个巨大的物体，如地球，产生重力场。这个场对所有它表面附近的物体都产生一个向下的力。
An enormous object, like the earth, generates a gravitational field, this field causes a downward pull on all objects near its surface.
本文介绍了使用改性倾斜，使病人进行负重锻炼，如倾斜蹲，在重力减少环境。
This article describes the use of a modified tilt table that allows patients to perform a weight-bearing exercise, such as an inclined squat, in a gravity-reduced environment.
