| 摘 要： | 对 4 1个样品的激光法与传统法 (筛析部分—沉析部分 )的粒度分析成果 (粒级百分含量、粒度参数和海陆相样品的粒度成果 )作了相关对比。找出 2种分析方法之间的内在联系 ,以期在将来的粒度分析中 ,可以通过参数矫正来实现 2法的数据转换。从分析可知 ,海陆相沉积对样品的影响很小。 2种方法的原理不同 ,从而产生了激光法低估粘土部分百分含量的结果

| Abstract: | Correlation analysis between laser method and pipette sieve method of grain size measurement for 41 sediment samples has been reported in this paper. It includes the comparison of correlation coefficients and regression equations for each definite size percentage and the comparison of the regression equations between grain size parameters and also the comparison of size results between marine samples and terrestrial ones. It is expected that the internal connections of the two methods realize the data transfer between them in future work. It can be concluded that there are little differences between the results of marine samples and terrestrial ones. Laser grain size analysis underestimates the content of the clay fraction than traditional method does because of their different principles. |
