least significant digit

基本解释

Usually, you order them from right to left, with the right-most digit being the least significant digit.
通常，从右到左排列，最右边的数字是最低有效位。
Instrument accuracy is usually specified as a percent of reading, plus a percentage of range (or a number of counts of the least significant digit).
仪器的准确度通常规定为读数的百分数，加上量程的百分数（或者最低有效位的字数）。
To compensate for this, the least-significant digit is removed from the end of a time difference resulting in a useful, but less specific data point.
为了弥补这个缺陷，从时间差异的末尾中删除最不重要的数位，得到一个有用但特定性较低的数据点。
