請問各位大大@@ 在WSJ看到一段如下: If interest rates rise faster than inflation, owners could get squeezed, especially if they have floating-rate debt, experts say. "These tight [yields] rates will have a very small margin of error,"XXX says. 請問最後一句: "These tight [yields] rates will have a very small margin of error,"中的 these tight yields 指的是通膨率和資產報酬率(yield)嗎?它們有小範圍的誤差??這句子究竟怎麼翻@@ 謝謝><
