平等公理

axiom of countability───可数性公理

income inequality───[劳经]收入不平衡；所得不均

air quality───空气质量

axis of evil───邪恶轴心

axis of evils───邪恶轴心

dose of reality───现实的剂量

good quality───良好品质，高品质；好质量

This system is self-suffient in the sense that if we wish to deduce an equality involving only some of the three functions, then we need only to make use of the corresponding axioms.───本系统中的各组原始公理还是自足的，即如想推出只含某些函数符号的永真公式时只须使用相应的公理便成。

We can use these axioms and the usual properties of equality to establish additional properties of integers.───我们使用这些公理，以及方程的常见属性来构建整数其他的属性。
