Based on the method of anti-seismic computation of underground structure and the theory of impulse response function, a generalized impulse function method applied to the time ?history seismic response of underground structure was proposed.

Equivalent load density models for feeders based on pulse function;

The breakdown current and the corona current are represented by a new pulse function and a double exponential function respectively.

With the pulse function completely shows that the forces that the pellet receives With step function deduces the equation of the pellet s movemen

The impulsive functions not using any extra conditions and the semigroups being analytic or compact, the author obtains the existence results of mild solutions and uniqueness of classical solutions by the method of e.

In the paper,dynamic impulse response model and method of time series are used to calculate the radiation ability.

Period impulse function and Riemann lemma;

On a property of impulse function;

When there are impulse functions or its derivative and its integral in the convolution, the computation will be convenient if we use the operator methods and combine the basic properties of the convol.
