And I think people would start looking to see, well, maybe other dimensionless ratios like the ratio of the mass of the electron to the mass of the proton are changing.

而且我认为人们也会开始考虑，像电子的质量对质子的质量的比值，也许其他无量纲的常数也在发生变化。

But the acceleration it produces on the elephant and on the mass, are in an inverse ratio of their masses.

但这个力使大象和物体产生的加速度,与它们的质量成反比

That is why we don't worry about the motion of the nucleus 1 because the ratio of mass is about 2,000 to one.

这就解释了为什么我们不担心,原子核运动起来,因为原子核和电子的质量比约为2000：

But accurately working out Mathilde's volume (necessary because density is the ratio of mass to volume) was harder.

ECONOMIST: Asteroids

The AMS paper will report the positron-electron ratio in the mass range of 0.5 to 350 Gigaelectronvolts.

BBC: Alpha Magnetic Spectrometer to release first results

The most likely alternatives, butter and pig fat, were ruled out using a technique called isotope-ratio mass spectrometry, which measures the molecular weights of the chemicals in a sample.
