摘　　要：通过用不损害生物活性的材料固定压载水样中的微藻,来寻找合适的固定液,并探讨最佳的固定方案。实验结果表明:常用的琼脂、聚乙烯醇、明胶以及海藻酸钠都能有效地固定压载水中的微藻。综合考虑固定液浓度和温度的影响,确定6%聚乙烯醇溶液的固定效果最理想。同时,活性对比实验亦表明:将聚乙烯醇加入盐藻和异湾藻液并不会对其活性产生影响。Various materials without harm to activities of the organisms were chosen and tested to fix micro-algae. Subsequently, a best solution is explored to fix the micro-algae in the ships＇ ballast water sample. The results of the research indicate that Agar, Polyvinyl Alcohol （hereafter refer to PVA）, Gelatin and Sodium Alginate can fix the micro-algae in the ballast water effectively, while 60/0 PVA solution is the best choice as considered comprehensively. Meanwhile, biological active comparison experiments also show that there is no influence on the activities of the Dunaliella salina and Heterosigma akashiwo after PVA is added into the samples.
