汉语拼音：zhòng lì chǎng

一般指地球的引力场。在地面附近的局部范围内，通常可把重力场看成均匀力场。在重力场的同一位置，任何质量的物体都具有相同的重力加速度。重力加速度实质上是描述重力场强弱的一个物理量。

重力场 [zhòng lì chǎng]

1. 某区域范围而非某一特定点之力或加速度所组成之重力集合，其为位置之函数，如地球重力场。　　重力场为力场的一种，只有重力作用。

• And the proximity of a gravity well meant Patterson was backed into a corner. It would be a slaughter.

  接近重力场意味着皮特寻跑进了一个死角，接下来的是一场屠杀。

• When the ratio was large enough, the difference between the centrifugal and gravitational tests would be so small could be be ignored.

  当比值足够大时，离心试验结果趋于稳定且与重力场试验结果之差可忽略不计。

• One of the fundamental scientific objectives of modern geodesy is to determine the high precision and high resolution earth gravity field.

  确定高精度和高分辨率地球重力场模型是现代大地测量的基本目标之一，卫星重力计划就是基于这一目标实施的。

• Unlike other satellites, it has none of the usual moving parts that could interfere with the gravity measurements.

  不像其它卫星，它没有通常的会干扰重力场测量的移动部分。

• Describe, and use the concept of, weight as the effect of a gravitational field on a mass.

  描述和利用重力是重力场作用在物体上的效果的概念。

• This dark matter provides the extra mass, which in turn creates gravitational fields strong enough to hold the clusters together.

  这些暗物质轮流产生重力场以提供足够的附加质量将星团聚集在一起。

• Our current Moon did not emerge from the Earth, but was captured by Earth's gravity field during this tumultuous time.

  我们如今的月亮不是来自于地球，而是在这个混乱的期间被地球的重力场捕获的。

• Its suite of detectors designed to measure the planet's gravitational field in detail will be able to deduce Jupiter's underlying structure.

  它的那一套探测设备将用于在细节层次测量这颗行星的重力场，这将可以用于推断木星的内部结构。

• An enormous object, like the earth, generates a gravitational field, this field causes a downward pull on all objects near its surface.

  一个巨大的物体，如地球，产生重力场。这个场对所有它表面四周的物体都产生一个向下的力。
