介壳虫

Over the last three decades,measurements of the δ13C and δ18O values of ostracode shells have been extensively used in lake palaeoenvironmental reconstruction.

由于湖泊生物碳酸盐样品不同的前处理方法可能会影响到稳定同位素测试结果的重现性和辨析率以及实验室之间数据的可比性，采用有效的方法对介形虫壳体进行预处理是保证介壳稳定同位素测试的一个关键环节。

Many methods for sample preparation have been applied in stable isotope measurements of ostracode shells from lake sediments. However, for stable isotope measurements of biocarbonate samples, different methods will probably affect the resolution, reproducibility and inter-laboratory comparison of the measurement results.
