1、1,关于内表面积我来补充一句，就是当短半轴长度为长半轴一半时，不含直边时，椭圆封头的内表面积和体积近似计算公式为：1）：内表面积=1.084（2长半轴）22）：体积1.047长半轴32，椭圆形封头的内表面积和容积数据表：椭圆形封头的内表面积和容积公称直径Dg曲面高度h1直边高度h2内表面积F（m2)容积V（m3)300（350）75250.1210.005388250.160.00802400100250.2040.0115400.2230.0134450112250.2540.0158400.2750.0183500125250.3090.0213400.3330.0242500.3490.
