摘　　要：针对所提出的用空气室引发水力共振以增强脉冲水射流的设想，应用水力瞬变特征线解法，建立系统的数学模型，差分网格只取脉冲源、空气室和喷嘴3个边界点，采用变时步法解算。这种方法具有灵活性大、受限制小、便于使用的突出优点。Applying the Method of Characteristics, the paper structures the mathematic models for analyzing the phenomena of pulsed water-jet system embodied air-chamber. The differential grid has three boundaries only, eg. pulse source, airchamber and nozzle, none interior node being involved. For dealing with the condition that the lengths of upstream and down- stream sections may be unequal, the novel Variable Time Step Method is adopted. This analysis technique has the glaring advantages of flexibility, less limit, and convenient for use.
