Under the principle and structural characteristics, a new type of excitation circuit is designed, which has simple structure, and also could solve switch on and off oscillation problems bothly.
In this paper, the oscillation properties of solutions under a kind of boundary conditions for impulsive hyperbolic differential equation of neutral type are studied.

The results of the test for the second order oscillation link and the test for typea turntable show that the software has correct test result, higher precision and real time characteristic.
