The adjoint system integrals for time free, optimal N -impulse transfer during a firing peri- od in 5-phase selected are derived.

3-D profilometry for the impact process with marked fringes tracking;

With the development of scientific research and technical production, 3-D shape dynamic measurement has been generally lucubrated in some fields such as high-speed, hydromechanics, stress analysis, impact process, explosion process and so on.

In order to ensure thatair-drop mine fuse safety unit can act effectively while air-drop sea mine enters water, we need know theimpingement acceleration signal peak value and pulse width of the air-drop mine in the process of entiretrajectory impingement such as opening an umbrella overhead , impinging entering water an.

This paper introduces the design of pulse measurement and transition process system based on virtual instrument.

In the experiments we measured the direct-current resistance at the high-temperature superconducting tape joint and applied the tape with over-current AC impulse.
