本文用改进的Walkley-Black滴定法和LECO燃烧法分析了33个湖相和浅海沉积物样品的有机碳含量。两组数据的比较产生斜率为0.992、截距为0.00且相关系数为0.989的回归线。因此，两种方法获得的结果完全一致。由于滴定法涉及很少的设备或操作员培训，它可以用于小型实验室和学校，这些实验室和学校缺乏足够的资金或样品量来购买或证明更快但更昂贵的LECO仪器。
ABSTRACT Thirty-three samples of lacustrine and shallow marine sediments have been analyzed for organic carbon content by a modified Walkley-Black titration method and by the LECO(FOOTNOTE 3) combustion method. Comparison of the two sets of data yields a regression line with a slope of 0.992, intercept of 0.00 and a correlation coefficient of 0.989. Thus results obtained with the two methods agree precisely. Because the titration method involves little equipment or operator training it can be used at small laboratories and schools that lack sufficient funds or volume of samples to purchase or justify the faster but more expensive LECO apparatus.
