。最近，许多研究都集中在Takahashi引入的James型常数上。本文给出了关于James型常数的两个不等式，并证明了这些不等式可以用来估计某些具体空间的James型常数的值。特别地，对于任意τ≥0，我们已经计算出了詹姆斯型常数J X，t (τ) （t1 - l2）的精确值。
. Recently, many recent studies have focused on the James type constant introduced by Takahashi. In this study, we have presented two inequalities on the James type constant, and shown that the inequalities can be used to estimate the values of James type constant for some concrete spaces. In particular, for any τ ≥ 0, we have calculated the exact values of James type constant, J X,t ( τ ) of l 1 − l 2 , for t ≥ 1 . .
