The algorithmic relaxes the strict limit on sample frequency, and can guarantee SGUUB(semi-global uniform ultimate boundedness) of the closed-loop system.

该算法对采样频率无严格限制，最终可确保系统闭环半全局一致有界收敛。

This paper described the fact that we pre-process sample by SPE, then Semi-volatile Organic compounds in drink source water were analyzed by GC-MS method, the result was discussed.

用固相萃取的方法对样品进行预处理，再进行GC - MS分析测定，对饮用水源水中的痕量半挥发性有机化合物进行了测定，并对结果进行了讨论。
