说明：  微处理机中的存放顺序有正序(big endian)和逆序(little endian)之分。正序存放就是高字节存放在前低字节在后，而逆序存放就是低字节在前高字节在后。例如，十六进制数为A02B，正序存放就是A02B，逆序存放就是2BA0。
(The order of a microprocessor is stored in the sequence (big endian) and reverse (little endian) of the points. Sequence is the high byte is stored low byte first store in the post, while the reverse is stored high byte first byte in the post. For example, the hexadecimal number A02B, the positive sequence storage is A02B, stored in reverse order is 2BA0.)
