摘要
用原子吸收分光光度计、可见光分光光度计对甘肃鼢鼠(Myospalax cansus)骨骼中Ca、K、Na、Mg、P 5种常量无机元素作了测定。结果表明,甘肃鼢鼠骨骼中5种元素含量依次为Ca>P>K>Na>Mg,Ca含量维持较高水平;同一元素在不同部位骨骼的含量存在差异,部分含量差异显著,5种元素总量在不同部位骨骼的分布顺序为:后肢骨>前肢骨>脊柱;根据甘肃鼢鼠骨骼Ca与P比值推断二者主要以羟基磷灰石形式存在。
The contents and distributions of the inorganic Gansu Zokor （Myospalax cansus ） were determined macroelements-Ca, K, Na, Mg and P in skeletons of by AAS （Atomic Absorption Spectrometry ） and SP （Spectrophotometry）, The results are as follow： The contents of these five elements in Gansu Zokor＇ s skeletons are in the turn of Ca 〉 P〉 K 〉 Na 〉 Mg, which is mainly due to the food habit of the animal. The contents of these five elements differ in different parts of skeletons, some of which differences are significant by t-test （ P 〈 0.05）. The total amount of these elements also differs in different parts of skeletons： skeletons of forelimb 〉 skeletons of backlimb 〉 backbone, and this may relate to the important roles these skeletons play when moving. Gansu Zokor has a normal content of Ca in skeletons, according to the ratio of Ca to P, these two elements may exist as a form of Ca10 （ PO4 ）6 （OH）2 in skeletons of Gansu Zokor.
