南的sheng gonglo超声功率(ultr巴扣nicp洲阳r)超声场中单位时间内通过某一面积的声能，单位为W。在自由平面波或球面波声场中，通过面积S的平均声功率为: 甲=夕25明81脚式中6为面积S的法线与声波法线之间的角度，p为声压，p为介质密度，。为声速。测量超声功率的方法有辐射压力法、电学法、光衍射法和t热法。由于辐射压力法易于操作和校准，被IEC推荐为兆赫频率范围内液体中超声功率测量的标准方法。毫瓦级和瓦级超声功率基准装置均由自动电子徽量天平、消声水槽和反射靶悬吊系统组成。lmw一义幻mw超声功率所产生的辐射力约为零点几至几百微牛，而0.ZW一20W超声功率产生的辐射力约为零点几至几十毫牛。它们的测量不确定度均为5%(包含因子k=2)。这两套基准装置的主要区别，是毫瓦级装里为了减小水的表面张力影响和靶的悬吊系统扭转引起的波动，采用了单根悬吊丝，测量时超声垂直向上辐射。(熊大莲)
