bua的音标

Be sure to stop by the Bua Bok Cave and marvel at unique geological formations as well as the verdant tropical rainforest.

波宝（Bua Bok）岩洞一定不容错过，一定要进去见识一下独特的地质形态以及如翡翠般苍翠的热带雨林。

Conclusion Using the technique of ultrasound diagnosis ( USD) to measure the bone density, BUA ( Broadband Ultrasonic Attenuation) is an im-portant statistic data, SOS ( Speed of Sound) is of no characteristic importance.

结论用超声诊断技术（USD）测骨密度值，声量减弱（BUA）值是具有统计意义的重要参考值，声速（KE）值不具备此特点。

Methods An ARM embedded system was used to measure the speed of ultrasound, the broadband ultrasound attenuation ( BUA) and the stiffness.

方法：设计采用ARM嵌入式系统，通过超声技术测量并计算足跟骨处的超声速度、宽带超声衰减值和硬度系数。
