目的： 在进行海洋生物活性物质分离筛选的过程中，我们发现柄海鞘中的一个具有很高药用价值的活性物质—海鞘醇，这是一个既具有还原性有具有较强氧化性的甾醇类有机化合物，实验表明它具有极高的对抗乙型肝炎病毒的体外活性。

Unreducibility of emergence can be concretely explained as existence of downward causation ontologically and existence of different descriptive language of different levels epistemologically.

在此前提下，将复杂系统突现的基本特征具体化：突现的整体性具体化为复杂系统全局模式的出现；不可预测的新颖性具体化为非迭代模拟的不可预测性；不可还原性具体化为在本体论上存在下向因果关系、在认识论上存在不同层次的描述语言。

Study on thermostable and salt-tolerant water-soluble polymers with super- high molecular weightChemical degradation of HPAM in aqueous solution and its influence factors werestudied. The oxidative degradation mechanism, including auto-oxidation and chainscission two processes, having longer kinetic chain length was established. Notably, inthe presence of the reductive impurities the oxidative degradation of HPAM inaqueous solution is remarkably accelerated.
