摘　　要：对近似2:1椭圆形封头可等效代替2:1椭圆形封头的几个核心论点有不同认识,指出:认定“形状相近或相当的碟形封头与椭圆形封头其设计也总是一样的”,说“两者是一回事”的提法不切实际。Different consideration on some key point of view of that the 2:1 elliptic head could be replaced by similar 2 :1 elliptic head was existed. And point that the statement of 'the design of similar shape or equal dished head was the same as the design of elliptic head' and the statement of 'Both was one thing' were unsuit-ed to the actual situation.

关 键 词：近似椭圆形封头 标准椭圆形封头 等效代替 分析
