By using the renorming of Banach space, it was proved that every Banach space has an equivalent norm which is not strongly rough, and every Banach space has an equivalent norm which is not even, and every real Banach space has an equivalent norm ‖| · ‖| , such that ( X , ‖| · ‖| ) is not strictly convex or smooth.

应用再赋范方法，得到了任意Ｂａｎａｃｈ空间都存在不是粗的等价范数，任意Ｂａｎａｃｈ空间都存在不是平的等价范数等结论，证明了任意实Ｂａｎａｃｈ空间一定存在等价范数‖｜·‖｜，使得（Ｘ，‖｜·‖｜）既不是严格凸的，也不是光滑

This indicates that the nonsquare constant is not necessary to be 2~(1/2) in some spaces with P_λproperty for someλ, and that P_λproperty does not imply strict convexity or even uniform convexity.

其次,介绍了关于非方常数,等腰正交的基本定义和基本结论,并且构造了一个具有P_λ性质的Banach空间,计算出了该空间的非方常数,从而说明了对于某特定的λ,具有P_λ性质的赋范空间其非方常数不一定为2~(1/2) ,同时也说明了具有P_λ性质并不能保证赋范空间的严格凸性或者一致凸性。
