Dr Packard's model gets round this by abandoning simple logarithmic transformation in favour of a more complicated, so-called nonlinear model.
通过舍弃简单的对数转换进而采用更复杂的非线性模型，帕卡德博士的模型解决了这个问题。
From here, it is possible to round-trip by reversing the transformation (looking in the class attribute for the specializing element name, and renaming the current element to match).
这种情况下可以通过逆反转换返回原来的形式(在class属性中查找专门化元素名并重新命名当前元素以与其匹配)。
