Big -endian是将高位字节存储在内存的低地址中，将低位字节存储在内存的高地址中。
Big-endian means that the most significant byte is stored at the lowest memory address and the least significant byte is stored at the highest memory address.
而little -endian意味着最低位字节存储在最低地址(按低位优先的顺序存储字)。
Little-endian means that the least significant byte has the lowest address (the word is stored little-end-first).
Little - endian是将低位字节存储在内存的低地址中，将高位字节存储在内存的高地址中。
Little-endian means that the least significant byte is stored at the lowest memory address and the most significant byte is stored at the highest memory address.
其他三个低位字节称为记录标识符 （RID），其中包含标记的MSB 所引用的元数据表中的行索引。
The lower three bytes, referred to as the record identifier (RID), contain the index of the row within the metadata table to which the token's MSB refers.
这就是说，在x86系统上，最低位字节(最小值)首先存储在ll的第一个字节中；在PowerArchitecture系统上，它们则存储到最后。
That is to say, on the x86 system, the least-significant byte (the smallest values) are stored in the first byte of ll; on the Power Architecture system, they're stored in the last.
图像字节内的位填充次序：最高位首先填充还是最低位首先填充。
Fill order of the bit within the image bytes: most significant or least significant bit first.
统计8字节块中每字节中的1的个数，如果1的个数为偶数，那么就设置最低位为1使它成为奇数。
Count the number of ones in each byte of the 8-byte block; if the number of ones is even, make it odd by setting the least significant bit to one.
如果一个字节中1的个数已经为奇数，那么就将它的最低位设置为零。
If the number of ones in a byte is already odd, you will set its least significant bit to a zero.
如果一个字节中1的个数已经为奇数，那么就将它的最低位设置为零。
If the number of ones in a byte is already odd, you will set its least significant bit to a zero.
