In this paper, we discuss a problem of multiplicative Diophantine approximation of the expansions under different bases restricted on a line. More specifically, let φ : ℕ → [ 0 , ∞ ) be a positive function. A dichotomy law of the Hausdorff measure for the following set:
M ( φ ) = { x ∈ [ 0 , 1 ] : ∥ 2 n x ∥ ⋅ ∥ 3 n x ∥ < φ ( n ) for i.m. n ∈ ℕ } ,
is obtained, which depends the convergence or divergence of certain series.

一条线上不同基数下展开的倍增二苯胺逼近
在本文中,我们讨论了在一条线上限制的不同基下展开的乘法丢番图逼近问题。更具体地说,让φ : ℕ → [ 0 , ∞ ) 成为正函数。下列集合的豪斯多夫测度二分法:
米 ( φ ) = { X ∈ [ 0 , 1 ] : ∥ 2 n X ∥ ⋅ ∥ 3 n X ∥ < φ ( n ) 对于我 n ∈ ℕ } ,
得到,这取决于某些系列的收敛或发散。
