A general relationship is derived for the area of the sample curve for a given stage in the life-cycle, in terms of the mean survival rate and duration and the number entering the stage. The influence of recruitment, development and mortality patterns on the area of the sample curve is investigated. The results indicate a simple method of analysing stage frequency data to produce a best estimate of the number entering each stage. A test example, using simulated data, is provided with a discussion of the method in relation to other techniques based on the area of the sample curve.
根据平均存活率、持续时间以及进入该阶段的个体数量，推导出了生命周期中给定阶段样本曲线面积的一般关系。研究了补充、发育和死亡模式对样本曲线面积的影响。结果表明了一种分析阶段频率数据以获得进入每个阶段个体数量最佳估计值的简单方法。给出了一个使用模拟数据的测试示例，并讨论了该方法与基于样本曲线面积的其他技术的关系。
