1) the mean difference of pressure
平均声压
1.
The formula of average pressure and the mean difference of pressure are presented as function of frequency and phase;it is known that uniform distribution of pressure amplitude can be obtained by the sets of values of frequency and phase.
声波的频率及相位影响三频声场的均匀性,通过对平均声压与声压均方差参数分析可知,频率及相位的不同取值会同时影响声波总能量与均匀性,可以通过取合适的参数实现声场均匀性。
2) average sound pressure level
平均声压级
3) arithmetical average sound pressure
算术平均声压
5) On the algorithms of sound pressure level average
论声压级平均算法
6) average sound velocity
平均声速

补充资料：平均动脉压
平均动脉压
mean arterial pressnre
在一个心动周期中动脉血压的平均值。一般说来，平均动脉压大约等于舒张压加三分之一脉压，即舒张压+(收缩压-舒张压）×1/3。
