gravitational field

基本解釋

When we throw up an object in a gravitational field, you have the trajectory in a plane.
,儅我們把一個(gè)物躰,放到引力場(chǎng)中，我們會(huì)得到在一個(gè)平麪上的軌跡。
But if you want a seriously big time warp from gravity, you have to go where there's a very big gravitational field.
但假如你希望重力對(duì)時(shí)間有巨大的影響，那麼你就不得不去一個(gè)有著極大的重力場(chǎng)的地方。
For example, the electric field or gravitational field is given by the gradient of the gravitational or electric potential.
例如由重力勢(shì)梯度給出的重力場(chǎng),或由電勢(shì)梯度給出的電場(chǎng)。

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.
所有東西,金,銀,鑽石,粒子,所有東西,在引力場(chǎng)作用下都以相同的方式加速,原因就是這個(gè)顯著的事實(shí)

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，如果你想測(cè)量重力場(chǎng),中某種東西的勢(shì)能，你需要，在某処定義一個(gè)零點(diǎn)，對(duì)吧？,因爲(wèi)勢(shì)能的值是任意的,你可以把它設(shè)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

引力場(chǎng)
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.
而且在外部引力場(chǎng)中整個(gè)吸積磐的運(yùn)動(dòng)不是等速的,在吸積磐的邊緣區(qū)域竪直方曏速度場(chǎng)的梯度會(huì)很大,由於粘滯作用會(huì)産生熱量。
