谐波系数 meaning in English
harmonic coefficient
harmonic constant
harmonic wave factor
Examples
- It is studied that small inclusions in aluminum alloy are detected by ultrasonic transmission method in this paper . frequency analysis of the ultrasonic signal is done . harmonic factor and relative valid spectral power are calculated
本文采用超声穿透法对ly12铝合金板材细小夹杂物进行了检测试验研究，并对超声信号进行了频谱分析，计算了谐波系数和相对有效谱功率。 - There are functions such as drawing the chart of amplitude - frequency and phase - frequency , calculating and displaying the highest peak value , the total sum of amplitude and the effective line - breadth of the signal in the program . so an effective technical means is supplied for the analysis of ultrasonic signal
软件系统具有幅频图及相频图的绘制、最高峰值、谐波系数及有效谱宽度的计算及显示等功能，从而为超声信号的频谱分析提供了极其有效的技术手段。 - The harmonic factor raises with the growth of volume percentage of hardening particles no mater what detecting direction is . but it is not a linear variation course . the harmonic factor mounts up slowly under the critical value but increases rapidly while exceeds the critical value
在正、逆向检测时，随着强化粒子体积百分数的增加，在有效频带范围内谐波系数同时单调增加，但其变化是非线性的，即在临界值以下，谐波系数的变化趋于平缓，而超过临界值以后，随着强化相粒子体积百分数的增加，谐波系数快速增加。
