gravitational field

基本解释

When we throw up an object in a gravitational field, you have the trajectory in a plane.
,当我们把一个物体,放到引力场中，我们会得到在一个平面上的轨迹。
But if you want a seriously big time warp from gravity, you have to go where there's a very big gravitational field.
但假如你希望重力对时间有巨大的影响，那么你就不得不去一个有着极大的重力场的地方。
For example, the electric field or gravitational field is given by the gradient of the gravitational or electric potential.
例如由重力势梯度给出的重力场,或由电势梯度给出的电场。

But others note that Jupiter's powerful gravitational field can just as easily send an object into Earth's path as push it deeper into space.
Everything -- gold, silver, diamonds, particles -- everything accelerates the same way in a gravitational field, due to this remarkable fact.
所有东西,金,银,钻石,粒子,所有东西,在引力场作用下都以相同的方式加速,原因就是这个显著的事实

You know, if you want to measure the potential energy of something in a gravitational field, you have to define the zero somewhere, right, because it's arbitrary. You can set it anywhere you want. It's the same with enthalpy.
你知道，如果你想测量重力场,中某种东西的势能，你需要，在某处定义一个零点，对吧？,因为势能的值是任意的,你可以把它设定在。

Its gravitational field thus bends and focuses the light from the distant object, making it appear closer than it really is.
ECONOMIST: Japan’s new telescope

the field of force surrounding a body of finite mass in which another body would experience an attractive force that is proportional to the product of the masses and inversely proportional to the square of the distance between them

Moreover, the movement of the disk in the external gravitational field isn’t isokinetic. On the edge of the disk, the velocity field gradient of the Vertical direction would be great.
而且在外部引力场中整个吸积盘的运动不是等速的,在吸积盘的边缘区域竖直方向速度场的梯度会很大,由于粘滞作用会产生热量。
