对于金属导体引起的电场不规则畸变，采用有限元的方法计算场强以验证是否超出临界值。
And finite element method was adopted to calculate the electric field strength to find whether it is beyond the critical.
利用HIOKI3164和TOPVIEW31分析软件，可对交-直-交变频器中电压、电流、功率、频率进行准确测量，不论它是不规则波形还是畸变波形。
In AC-DC-AC VVVF, We can accurately measure voltage, current, power and frequency with The HIOKI3164 and TOPVIEW31 analysis software, even if the wave is irregularities and distortion.
试验表明其出口平均总压恢复系数较低，周向总压畸变指数较大，旋流较强且很不规则。
Test results show lower exit average total pressure recovery, larger circumferential total pressure distortion and stronger and more irregular secondary flow.
利用面阵CCD测量不规则平面物体面积时，图像畸变对测量精度影响很大。
In the area measurement of an object with irregular plane using area array CCD, the precision is greatly influenced by image distortion.
由于局部放电脉冲波形是不规则的，显然，它们的频谱是不同的，这将导致在测量点上脉冲波形的畸变。
Since a partial discharge pulse waveform is irregular and the spectrum of each pulse is different, a pulse wave form will be distorted at the measuring terminal of the circuit.
