For example, a date can be passed in the message using a fixed-size string representation of YYYY-MM-DD.

比如，可使用 YYYY-MM-DD 这样的定长字符串表示来传递日期。

A hash is the result of a cryptographic function that takes an arbitrarily sized string of data, performs a mathematical encryption function on it, and returns a fixed-size string.

哈希是一种加密功能所获得的结果，这种加密需要获取任意大小的字符串数据，并用算法对其进行加密，然后返回一个固定大小的字符串。

The conversion costs are all the more important for LOB input because of the potentially large size of the input string.

转换成本对LOB输入更加重要，因为输入字符串的大小可能很大。

b OK. In this example I'd use b. All right, as b get-- b is the thing that's changing as I go along here, but it could be things like, how many elements are there in a list if the input is a list, could be how many digits are there in a string if the input's a string, it could be the size of the integer as we go along. All right.?

好，在这个例子里我会用，因为b是一直在变的东西,但是也可能是如下情况：,如果输入是数组的话,变化的就是数组的元素数，如果输入是字符串的话,变化的就是字符串的长度，如果是integer的话,可能就是这个数的大小，对不对？
