抽象的。我们使用微 X 射线荧光结合 X 射线光吸收光谱来研究巨蛤（Hippopus hippopus）内壳层中物种特异性硫的分布。硫酸盐、含硫氨基酸和总硫谱表明无机硫酸盐是该双壳类贝壳的主要成分。内壳层中的硫分布显示出明显的年度波动，变化幅度超过一个数量级，从
Abstract. We used micro-X-ray fluorescence combined with X-ray photoabsorption spectroscopy to investigate speciation-specific sulfur profiles in the inner shell layer of a giant clam (Hippopus hippopus). The sulfate, S-bearing amino acids, and total sulfur profiles indicated that inorganic sulfate was the dominant component in the shell of this bivalve. Sulfur profiles in the inner shell layer showed clear annual fluctuations that varied by more than one order of magnitude, from
