目的 :研究分析牙结石及体内其它结石中的化学元素及其含量。方法 :用大型WSP -Ⅰ型光栅摄谱仪对牙结石、胆结石、泌尿道结石和颌下腺导管结石作光谱全分析。结果 :①各类结石都是生物形成的矿化物 ,属碳酸 -氢氧碳灰石类。②各类结石中的主要化学元素是钙、磷、镁、钠、硅、铁、铝和钾 ,其次为钡、锰、铜、铬等 2 2种微量元素。结论 :通过对结石的化学元素的测量 ,探讨防治结石形成的方法 Objective: To study and analyze the chemical elements and contents of dental calculus and other stones in the body. Methods: The total spectrum of dental calculus, gallstones, urolithiasis and submandibular gland duct stones were analyzed by a large WSP-I grating spectrometer. Results: ① All kinds of stones are biogenic minerals, which are carbonic acid-hydroxycarbides. ② The main chemical elements of various types of stones are calcium, phosphorus, magnesium, sodium, silicon, iron, aluminum and potassium, followed by barium, manganese, copper, chromium and other trace elements. Conclusion: Through the measurement of the chemical elements of stone, to explore the method of prevention and treatment of stone formation
