利用元素分析仪和原子吸收光谱仪分析了褶纹冠蚌(Cristaria plicata Leach)的四个不同培育阶段的珍珠的十三种元素的含量,以期从连续动态的角度探讨珍珠的形成机制。结果表明,随着育珠时间的延长,珍珠中Ca元素的含量是逐渐增加的,C和H元素的含量则是逐渐下降的。在微量元素中,Na、Cu、Zn、Mg和Sr的含量比较高,其中Na在晚期的珍珠中的含量显著高于早期的珍珠,而CuZn、Mg等其它微量元素则是在早期珍珠中的含量明显高于晚期珍珠,它们随着育珠时间的延长呈指数下降。
The content of thirteen elements of pearl in four different growth stages of Cristaria plicata Leach was analyzed by elemental analysis and atomic absorption spectrometry in order to discuss the formation mechanism of pearl from the perspective of continuous dynamics. The results showed that with the extension of the time of pearl, the content of Ca in pearl gradually increased, while the content of C and H decreased gradually. Among the trace elements, the contents of Na, Cu, Zn, Mg and Sr were relatively high, among which, the content of Na in late pearl was significantly higher than that in early pearl, while the other trace elements such as CuZn and Mg were in early pearl Content was significantly higher than the late pearl, they grow exponentially with the extension of time.
