harmonic

形容词[乐]和声的，悦耳的; [物]谐波的; 和睦的，融洽的; [数]调和的

名词[物] 谐波; [乐]泛音，和声; [数]谐函数，调和函数

1. 谐波：★ 谐波:(harmonic) 对周期性交流信号量进行傅立叶级数分解,得到频率为基波频率大于1的整数倍的分量. 我国供电系统频率为50Hz,所以5次谐波的频率为250 Hz. 7次谐波的频率为350 Hz. 11次谐波的频率为550 Hz,13次谐波的频率为650 Hz.

2. 谐音：高通过滤器(High Pass Filter)必然将会把不必要/不需要的低音率去除,这信号之后会被传到谐波发生器(Harmonic Generating),在这里,信号将会被相位移动(Phase Shift)和制造一些和输入信号有关的谐音(harmonic).

3. 谐振：因为半自动武器都要留较大公差才不会卡子, 还有传动系统会干扰枪管的谐振(harmonic), 因此手动的bolt action 都是比较准的. 这与制造技术无关, 而是不同导向之设计的结果. 因此在 1 MOA 精度以内的狙击枪, 都是手动的.

4. 调和：为实现无冲突周期性消息调度,PMS MAC协议采用了消息周期调和(Harmonic)机制,将共享无线信道方式转化为确定每个节点的消息发送调度时隙. 如称一个消息集为调和消息集时,当且仅当消息集中每个消息的周期为其他所有更小消息周期的整数倍.

5. harmonic：har; 谐波

1. 和声的
    Harmonic means composed, played, or sung using two or more notes which sound right and pleasing together.

    e.g. I had been looking for ways to combine harmonic and rhythmic structures.
           我过去一直在寻找将和声和节奏结合起来的方法。

2. 泛音
    Harmonics are musical notes which can be produced on certain instruments. Harmonics are higher and quieter than the main note being played.

1. The group's harmonic cohesion makes for an energetic and lively performance.

2. Inspired by Chinese poetry and calligraphy, he incorporates Chinese timbres and themes into Western conceptions of harmonic notions and chromaticism.
