说明：  CRC16多项式为 X16+X15+X2+1，其对应校验二进制位列为1 1000 0000 0000 0101；CRC-16码由两个字节构成，本文提供校验位计算VB原代码示例。
(The CRC16 polynomial is X16+X15+X2+1, and its corresponding check binary bit column is 1 1000 0000 0000 0101; the CRC-16 code is composed of two bytes. This paper provides an example of the check bit calculation VB original code.)
