序往上排了

好歹你说个0-1接近什么的理由也成啊。

发帖数: 13724 | 8 狗了一下，原来按键电话布局是在计算器布局出现后设定的，
有几个理论解释为啥按键电话布局如此。
It is pretty odd that a calculator and a touch-tone telephone have exactly
opposite layouts for their keypads, which have many identical components.
The reasons behind the differences are not known for certain, but a few
theories exist.
The first theory deals with the telephone's circuitry and tone-recognition
hardware. When the touch-tone telephone was being designed in the late 1950s
, the calculator and adding-machine designers had already established a
layout that had 7, 8 and 9 across the top row. Data-entry professionals, and
others who used calculators fairly regularly, were quite adept at
navigating these keypads. They could hit the numbers extremely quickly,
which was great for data entry, but not so great for dialing a touch-tone
phone. The tone-recognition technology could not operate effectively at the
speeds at which these specialists could dial the numbers. The telephone
designers figured that if they reversed the layout, the dialing speeds would
decrease and the tone-recognition would be able to do its job more reliably
. This theory has little proof to substantiate it, but it does make sense.
A second theory refers to a study done by Bell Labs in 1960. This study
involved testing several different telephone-keypad layouts to find out
which was easiest to master. After testing several layouts, including one
that used two rows with five numbers each and another that used a circular
positioning, it was determined that the three-by-three matrix that had 1, 2
and 3 across the top was the easiest for people to use.
Another theory is based on the layout of a rotary telephone. On a rotary
dial, 1 is at the top right and zero is on the bottom. When designing the
new touch-tone keypad, putting the 1 on the top-right didn't make much sense
, because Western writing is read from left to right. But putting 1 on the
top-left, and the subsequent numbers to the right, did make sense. Using
that formula, the resulting rows fell into place, with zero getting its own
row at the bottom.
All of these theories attempt to explain why telephone and calculator
keypads are exact opposites, yet no one theory can be pinpointed as the
definitive reason. It is common practice today to use the telephone-keypad
layout when designing new products that utilize a keypad, such as Automated
Teller Machines. |

这个比较是问为啥电话-计算器（which 被电脑“照抄”）不一样，也许我的语文表达
