The Hamming distance is used in telecommunication to count the number of flipped bits in a fixed-length binary word, an estimate of error, and so is sometimes called the signal distance.

汉明距离可以在通信中累计定长二进制字中发生翻转的错误数据位，所以它也被称为信号距离。

Here, what's different between autocrine and paracrine is that there's some distance between the cell that produces the signal and the cell that receives the signal, but it's not too great a distance because the blood system doesn't have to be involved.

自分泌和旁分泌的区别在于,旁分泌中,产生信号的细胞和接收信号的细胞,之间存在着一定的距离,但这个距离并不远,因为血液系统并不参与
