英文摘要：

It is explained that only a forced, non-damped, and typical sinusoidal pulse source can be the ideal one for producing a strong hydraulic resonance to promote the magnitude of pulsed water-jet. A novel scheme to make ideal pulse is pioneered, which consists of a constant discharge source and a by-pass cylinder in which the piston reciprocally moves with sinusoidal velocity to make the cylinder volume fluctuate sinusoidally. The techniques of using cam drive mechanism for electric reciprocating pump to gain an even piston velocity, an：l using cam or crankshaft mechanism for the by-pass cylinder to gain a sinusoidal piston velocity are put forward.
