| Abstract: | With the help of mechanics integral transfromation principle,we have not only derivated the second Lagramge equations but also gotten the differential equations of motion about micro-breadth oscillation system .In the meantime, we have also found the conditions that should be met for relative equilibrium state of the system and discussed the effect of micro-breadth oscillation to the state or frequency of canonical oscillation. In the last place, we have gotten correction formala for frequency. |
