R, meanwhile, is what’s called the universal gas constant.

同时， R 是所谓的通用气体常数。

But thanks to improving technology and precision, these objects with limited access and unreliable longevity are now being replaced with standards based on universal constants, like the speed of light.

但由于技术和精度的提高，这些访问受限且寿命不可靠的物体现在正被基于通用常数（如光速）的标准所取代。

If you measured the deflection accurately and worked out the mass of the mountain, you could calculate the universal gravitational constant that is, the basic value of gravity, known as G and along with it the mass of the Earth.

要是你精确测量那个偏差，计算大山的质量，你可以算出万有引力的常数即引力的基本值，叫做G同时还可以算出地球的质量。
