In this paper we introduced how to use uncertain relationship to simply calculate the zero position energy of one dimension linear harmonic oscillator, and then the resonant energy grade equation were gotten based on Planck hypothesis.

In the experiments of measuring Plank constant by the method of photoelectric effect, the raising point of the volt-ampere character curve of a photoelectric tube to each kind of monocromatic lights can be extracted by 3-ranking step-differential, precisely to 0.

Improvement on apparatus of Planck constant measurement;

Planck constant measured by progressive average method;

Curvature method of testing Planck constant in photoelectric effect experiment;

A brief review is presented of three fundamental physical quantities derived by Max Planck in 1912, referred to have as the Planck mass, Planck length and Planck time which had been arranged in the tables of 1986 and 1998 fundamental physical constants.
