摘要
分析了南黄海海域65个沉积物样品的激光法与综合法(筛析法—沉析法)的粒度分析结果,并作了对比研究。南黄海沉积物样品的激光粒度仪和筛析法测试结果很接近;激光粒度仪测定的细粒组分(>4Φ)的含量85%样品的测试效率达到75%以上,平均值为92%,表层沉积物黏土粒级的激光法与综合法分析结果呈弱正相关。用激光粒度分析南黄海海域沉积物结果可靠,可以替代传统的粒度分析方法。
We made a comparison of using laser method and comprehensive method(pipette analysis-sieve analysis)to do grain size analysis for 65 sediment samples from the South Yellow Sea area.The analysis result from the laser method is very close to that from the sieve method.Using laser granulometer to measure fine compositions(>4ф),85% of the samples could have an efficiency up to 75%,92% on the average.Results from the laser method are in weak positive correlation with those of the comprehensive method.The laser granulometric analysis method can replace traditional methods due to its reliability.
