It is, rather, a thing of sealing-wax and string, held together by arbitrary mathematical assumptions.

相反，它是一种密封蜡和绳子的东西，由任意的数学假设结合在一起。

Susy, as this theory is known for short, got rid of the arbitrary assumptions by predicting a set of heavier (and as-yet-unseen) particles, a " superpartner" for each known fermion and boson.

Susy，这个理论的简称，通过预测一组更重的（和尚未见过的）粒子， 即每个已知费米子和玻色子的“超级伙伴” ，摆脱了武断的假设。
