摘　　要：应用灰度对比法的原理建立了计算机X线片蛋鸡骨放射密度法。结果表明,铝阶厚度与灰度之间呈显著的线性关系(P<0.01,r=0.997),铝阶厚度变化可准确反映蛋鸡骨骼骨量变化,不同曝光条件对骨量值无明显的影响(p>0.05)。该方法简便,精确,重复性好,经济,为研究蛋鸡骨质疏松症提供重要的检测手段。The hone radiography density method with Computer- assisted X- my film was established in layers according to grayscale - contrast theory. The results showed that Aluminium wedge thickness had good linear relationship with its grayscale（P〈0.01, r=0.997）, the change of Aluminium wedge thickness could reflect variation of bone volume exactly, different exposure parameters had not significant effects on value of bone volume （P〉0.05 ）. This method plays an important role in the cage layer osteoporosis research, with convenient, enient, accurate,economical and good repetition.
