Even so I hope the following generalizations are representative .
即使这样，我也希望下面的归纳是具有一定代表性的。
In either case , generalizations cannot be properly tested .
无论哪种情况，归纳都不能被恰当地进行验证。
Generalizations that cannot be falsified , do not qualify as scientific .
归纳是不可被证伪的，因此是不科学的。
In short , given a training set , there are always at least two equally plausible , but totally opposite , generalizations that could be made .
总之，对于一个训练集，总是可以归纳出至少两个（形式）近似的，但完全相反的等式。
These difficulties do not preclude social scientists from producing worthwhile generalizations , but they are unlikely to meet the requirements of popper 's scheme , nor can they match the predictive power of the laws of physics .
