SIFR

常见例句

The Arabs refer to the zero as Siphra or Sifr from which we have the English terms Cipher or Cypher.
阿拉伯人作为斯夫拉（Siphra）或斯夫（Sifr）来提及“零”，我们有英语术语是Cipher（密码）或Cypher（翻译）。
Thus it is evident that the term Cipher is derived from the Arabic Sifr which in turn is quite close to the Sanskrit term Shubra.
因此显然地，术语Cipher是源自阿拉伯的Sifr，依次就是与梵语术语Shubra（萨巴拉）相当接近。
