But that depends on negligible inflation; and given that the current American rate is 3.8% and that the average rate since 1900 has been 3.1%, this is a big risk for investors to take.
但前提是几乎没有通货膨胀;鉴于当前美国通胀率为3.8%,自1900年以来的平均通胀率是3.1%,投资者购买国债风险就大了。
The portion of the current confined to the surface layer becomes negligible.
