基本解釋

Broadband ultrasound attenuation(BUA) reflects the degree of bone mineral density.
寬帶超聲衰減（BUA）反映了骨密度疏密程度。

The broadband ultrasound attenuation and bone stiffness of the osteoporosis group were lower than the normal group(P0.01).
骨質(zhì)疏松組跟骨超聲振幅衰減平均值和骨硬度指數(shù)值均小于骨量正常組（P0.01）。
Methods An ARM embedded system was used to measure the speed of ultrasound, the broadband ultrasound attenuation(BUA) and the stiffness.
方法：設(shè)計(jì)采用ARM嵌入式系統(tǒng)，通過超聲技術(shù)測(cè)量并計(jì)算足跟骨處的超聲速度、寬帶超聲衰減值和硬度系數(shù)。
