The studyshows that Chetaev's model for mechanicalsystems with non-holonomic con-straints can be reduced to three essential factors:(1)a kind of direct sum ofjet bundles according to the constraints,(2)D′Alembert's principle,(3)pos-tulate of ideal constraints.The first among the three factors only has geomet-ric significance and the second is a fundamental physics principle independentof any constraints.

Have already perplexed people for morethan 100 years. In order to have solution of quantum mechanics problem, I have spent 43years in these issues. I thought that I have perfectly resolved a series of "hypothetical problem" of the quantummechanics, giving a quite good answers to a series hypothesis like quantum, Planckconstant, De Broglie relation, uncertainlyrelation, electron angular momentum etc. The answer is that Quantum mechanicschange into "Electronphysics". This is a greatleap in the development of physics.
