Gravitational waves can't exist in one or two-dimensional space.(在一维或二维空间,引力波无法存在。)
Their loveliness masks the toll exacted by the gravitational pull of their large bodies and the strain of daily survival.(他们的可爱掩饰了引力对巨大身体的拖累和日常生活的艰辛。)
The earth gravitational potential was developed up to 11th degree and 11th order for all of zonal and tesseral harmonic terms.(地球重力势对带谐、扇谐和田谐项都展开到了第11次和第11阶。)
This is the gravitational potential energy.(这是重力势能。)
Under the control of the Sun's gravitational force, each planet maintains an elliptical orbit and all of them travel in the same direction.(在太阳引力的控制下,每个行星都维持在一条椭圆形的轨道上,并按照相同的方向移动。)
We shift the gravitational center of it.(我们转移他的重力中心。)
There seems to be a kind of gravitational pull toward God.(似乎有一种引力把我拉向了上帝。)
Notice that the gravitational potential energy increases.(注意,这里,重力势能是增加的。)
Is that causes by gravitational attraction?(这是由万有引力作用产生的吗?)
