difference engine

差分机

不过到了1821年,他将大部分其他的兴趣都转移到了设计计算器上,并建造了一台能运作的计算机器,他称之为"差分机"(Difference Engine). 他设想差分机是一台能精准地计算任何数学函数至许多小数位数的机器. 很不幸地,巴贝奇是完美主义者.

difference tone

差音

这个低音相当于两个音振动数的差,叫差音(difference tone). 还可以产生第四个音(一个弱而高的合成音),它相当于两个音振动数的和,叫加成音(summation tone). 同光线可以反射一样,亦有声反射(reflection of sound),比如我们都听到过的回声.
