log·a·rithm AHD[lôʹgə-rĭY"əm, lŏgʹə-] D.J.[ˈlɔːgəˌrɪðəm, ˈlɒgə-]K.K.[ˈlɔgəˌrɪðəm, ˈlɑgə-]n.Mathematics(名词)【数学】- The power to which a base, usually 10, 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, 10 3 = 1,000; therefore, log 10 1,000 = 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,10 3=1,000;于是log 101,000=3。通常使用的有常用对数和自然对数
