alone is performed，completely accurate values will be obtained. We take the measurement of position for an oscillator
in a ground state for instance，and calculations show that the oscillator must gain some energy during the measurement
and the amount of the energy increases without bound along with degree of the accuracy. Therefore，neither
position nor momentum can be accurately measured.
Key words： position measurement; harmonic oscillator; energy divergence
