摘要：

There are two conservation quantities needed to derive conservation laws of sine-Gordon equation in a frame of laboratory reference. One of them could be derived easily with a standard process, but the other could not. After the gauge transformation e(-ithetasigma2/2) is introduced, we simply obtain the other one without any questionable assumption.
