求翻译：对数变换后，面板数据不会改变原有性质，可表征原变量的增加值，而且更容易消除观察数据的异方差问题和得到平稳序列。是什么意思？

After logarithmic transformation, the panel data does not change the original nature of the characterization of the added value of the original variables, and easier to remove the heteroscedasticity observed data and get a smooth sequence.

After the logarithm transformation, the kneading board data cannot change the original nature, may attribute the original variable the increase in value, moreover easier to eliminate the observed data the different variance question and obtains the steady sequence.
