1. It is shown that the numerical results of the total sound power level and the sound directivity of the original AFF agree well with those results by testing.
   结果表明，采用数值计算的方法得到原型轴流风扇的总声功率级和声源指向性与实验测试结果吻合较好。
2. In consideration of the directivity and acoustic power, the input voltage distribution of a loudspeaker array can be optimized and selected.
   运用该方法可以优化扬声器阵列的输入电压分布，获得指向性和声功率级二者兼顾的扬声器阵列。
