n.Mathematics （名词）【数学】

The power to which a base, usually 0, must be raised to produce a given number. Ifn x = a, the logarithm of a, with n as the base, is x; symbolically, log n a = x. For example, 0 3 = ,000; therefore, log 0 ,000 = 3. The kinds most often used are the common logarithm and the natural logarithm.

对数：为使某数等于一给定数而必须取的乘幂的幂指数。如果n x=a, ，以 a 为底 n 的对数就是 x ；表示为log na=x 。如，0 3=,000；于是log 0,000=3。通常使用的有常用对数和自然对数
