| 释义 | 〔logarithm〕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 〔toothed〕Having teeth, especially of a certain number or type. Often used in combination:有齿的：具有牙齿的、特指具有一定数量或种类的牙齿的。通常使用于复合词中：〔print〕To write (something) in characters similar to those commonly used in print.书写：以类似于通常使用的印刷字体的写（东西） |
