This paper briefly introduces the current development of supercavitating torpedoes in the world,and explains some confusable terms,including cavity,supercavitation, natural supercavitation ,air supercavitation and cavity number.

在简要回顾各国超空泡鱼雷发展概况的基础上，解释了几个易混淆的与空泡有关的新术语(空泡、超空泡、自然超空泡、通气超空泡和空泡数)，分析了超空泡的形成机理和特点，详细阐述超空泡鱼雷在总体结构和性能、动力推进、控制系统和弹道形式等方面的技术特点，概括超空泡鱼雷与普通鱼雷在结构外形、流体动力布局、系统组成和工作特性等方面的不同之处。

Furthermore, the research shows that the cavitator diameter has an important effect on the fineness ratio of the ventilated supercavity, which is not the same as the natural supercavity.

此外，研究表明空化器直径对通气超空泡的细长比的影响较大，这与对自然超空泡形态的影响不相同。
