The prominent advantage of this method is that the Earth angular momentum can be decoupled into massterm and velocity term and hence makes a complex problem simplified.
其突出的优点是可以使引起地球角动量变化的质量项和速度场项解耦，使原来较复杂的问题简化。

From that data, they've devised what they term the "habitability metric," a value representing a planet's temperature and mass that determines whether or not it can support life.
