【Methods】 With random sampling 0～1-year-old infants from Wuhan,the dual-energy X-ray absorptionetry(DEXA) was applied to measure their BMD,176 infants whose BMD were under normal were randomly assigned to two groups,one was the intervention group,in which infants were accepted synthetical interventional measures included sleep,dietary structure,activity in outdoors and appropriate calcium supply.
【方法】随机抽取武汉地区0~1岁婴儿,采用双能X线吸收法(the dual-energy X-ray absorptionetry,DEXA)检测其骨密度,将BMD异常的婴儿176例随机分为两组:一组为干预组,从第一次测试之日起在睡眠、膳食结构、活动量、日照时间及补充维生素D和钙剂方面采取综合干预措施,另一组为对照组,采用自然育儿方法。

补充资料：传能线密度
分子式：
CAS号：

性质：又称定限线碰撞阻止本领。以L△表示。可以写为L△=(dE/dx)△，dx是粒子所经距离，dE是在能量转移小于某一定值△条件下，由于碰撞而损失的平均能量。△通常是指一段射程，也可表示能量。它们分别可以称为射程截止LET和能量截止LET，如无说明，LET通常是指能量截止LET，单位为eV/m。如让△=∞，则LET在数值上与阻止本领相同。
