      * ## 检材编码
-     * ```
-     * JC <物证编号后 28 位> <顺序号4位>
-     * 例如:
-     * JC 5201010400002020030002 0000001 0001
-     * 合计 34 位
-     * ```
-     * 一份物证, 有可能会多次送检。每次送检的时候, 在原来的顺序号上递增。
-     * 定义这个编号的时候有点纠结, 有两个方向的关联: 在案件号上扩充、在物证号上扩充。我们选择在物证号上扩充。
-     * 检材编码的长度不一定刚好是 34 位！我们取“物证编号后 28 位”时, 其实是去掉物证编码前第1个字符后剩下的部分。
-     * 如果物证编码不是 29 位, 那么取到的就不是 28 位, 而是物证编码长度减1位。
