潮流计算程序，初始值使用高斯赛德尔法迭代所得，具有很高的精度和求解效率。(Flow calculation procedures, the initial value of iteration proceeds using high Sisaideer method with high accuracy and solution efficiency.)

频域波束成形算法，适用于所有一维和二维阵列的波束成形计算。对于采样时间较短的信号，采用了2次分段，对于采样时间足够的信号则只需要1次分段计算。计算结果包含成像图结果和各扫描点处的频谱结果(Frequency domain beamforming algorithm, applicable to all one-dimensional and two-dimensional array beam forming calculations. For shorter sampling signal, using a second segment, the sampling time sufficient signal need only 1 segment calculations. Calculation results include the results of spectral imaging of the results of each scan point)
