冲杯实验结果表明：复合能场铸轧板的深冲性能明显优于普通铝板，其制耳率仅为1.7%。
The drawing experimental results show that the draw ability of cast-rolled strip under composite energy field was obviously better than the general one, and the earing ratio was only 1.7%.
结果显示，在触指的两端和对称制耳处金属充填相对困难，在弯曲变形区域零件的应力最大。
The results show that the metal filling is relatively difficult in both ends of the contact finger and the symmetry ears, the stress reaches to the largest in bending deformation.
以3004铝合金为实验材料，研究了异步轧制对该合金的变形织构以及相应的制耳率的影响。
Effects of cross shear rolling on the deformation textures and the deep drawing earing of 3004 aluminium alloy were studied.
由此提出新的设想：每个制耳对平均制耳率的贡献是不一样的，并以制耳的相对高度作为加权系数，从而推导出新的平均制耳率计算公式。
Asuming that the contributions of each earing to the earing ratio is different, and the relative heights are used as weight coefficients, a new calculation formula for earing ratio has been derived.
