About Measure

Abstract: In this paper, the limitation in the application of the Riemann integral is pointed out, and the Lebesgue Measure is educed by introducing a new partition, and the Messurable Set and the Unmeasured Set are mainly discussed. In the end, the method to construst a Unmeasured Set in is obtained,and a example of Unmeasured Set in is given.
