By making use of the integral method and some results of the functional differential equations, oscillatory properties of solutions of a class of lagging-type hyperbolic equations with variable time-lag were studied and a series of criterions on the oscillatory properties of the equations were established.

An attempt has been made to apply a gradient method for optimizing motor cars oscillatory parameter using microcomputers.

Some conditions are precented under which every solution of the equation is oscillatory, either tending to zero or tending to infinity as t tends to infinity.
