摘　　要：为探索胎儿组织钙含量特征及其状态与未成年人钙缺乏的关系 ,测定 4～ 10月龄胎儿 7种组织钙含量并进行统计分析。结果显示 ,胎儿组织钙含量是一非稳态变量 ,是时空环境的函数。组织钙含量随时间和组织重量增加而减少 ,使每克组织钙含量向降低的方向发展 ,这一特征可延续到 2 0岁左右。结果提示 ,胎儿和未成年人组织钙含量随生长发育而降低的生理特征增加了对钙缺乏的敏感性 ,是低龄人群钙缺乏的生理基础 。In order to probe the relationship between calcium content and its status in fetal tissue and minor's calcium deficiency. the calcium content of seven tissues of fetus aged 4 to 10 month was measured and analyzed. Results showed that the calcium content in fetal tissues was an unstable variable, and it was a function of spatio-temporal factors. Calcium content in fetal tissues reduced with the increase of age and weight of tissue, making a continuous decrease of the calcium content in per gram tissue. This characteristic could last to about the age of 20 years old of children. The physiological character that calcium content in tissues of fetus and minor decreases with the development can make people to be more aware to calcium deficiency, laying the physiological basis of calcium deficiency of the people in low age, providing the physiological information for adjusting and controlling the calcium nutrition of the fetus, minor and pregnant woman.
