摘　　要：应用薄膜理论应力分析，指出用JB／T4729－94中的椭圆封头替代JB／T4737－95中的椭圆封头是不妥的，并对制造过程中由于拉伸减薄而使用较厚钢板来制造封头时应注意的问题进行了论述。The film theory stresss analysis was used to show that it wasnot appropriate of replacing the elliptical heads in JB/T437 - 95with the elliptied heads in JB/T4729-94, and the noticeableproblems in the process of making the elliptical heads using thethicker steel plates were discussed.
