查询词典 harmonics

Music arranged for fingerstyle playing can include chords, arpeggios and other elements such as artificial harmonics, hammering on and pulling off with the fretting hand, using the body of the guitar percussively, and many other techniques.

Fingerstyle Guitar有个同义词是&Fingerpicking&。指弹吉他音乐通常包含和弦、琶音以及其他要素诸如人工和声、左手敲击与拉扯、利用琴体制造打击乐等等。

The proposed algorithm consists of forbidding unnecessary triggers for the inverter switches and do not need any additional circuits and off-line experimental measurement. The realization of algrithm is very simple, the harmonics in output waveform are small, and the algrithm resoves the pulsant when the system works at the low frequency. The proposed algorithm was applied to a PM synchronous motor drive system.

该算法可以省掉开关器件没有必要的开通和关断，不需要任何额外的硬件电路、离线的实验测量，算法实现简单，输出波形谐波含量小，较好地解决了系统在低频时输出电流的脉动；适用于永磁同步电机。

The frequency pairs of quadratical phase coupled harmonics are obtained by directly evaluating the generalized eignvalues of this matrix pencil without pairing.

通过直接计算该矩阵束的广义特征值确定二次相位耦合谐波频率对，从而避免解决配对问题。

The echolocation signals of Rhinolophidae and Hipposideridae are both long CF-FM with 1 harmonic and narrow FM bandwidth. But Rhinolophidae has longer duration, higher duty cycle and lower dominant frequency than Hipposideridae. All the echolocation signals of Vespertilionidae are short FM with 2-6 harmonics and wide FM bandwidth. Vespertilionidae has shorter duration and lower duty cycle than the other two families. There are obvious differences in dominant frequency between different species in this family.

菊头蝠科和蹄蝠科回声定位信号均为长CF-FM型，一般具有1个谐波，调频带很窄，但菊头蝠科的持续时间和能率环明显高于蹄蝠科，蹄蝠科能量最大处频率高于菊头蝠科；蝙蝠科回声定位信号均为短FM型，具有2～6个谐波，持续时间和能率环比其他两科低，调频带很宽，能量最大处频率在种间变化较大。

While trying to get a grasp of the septile aspect, I went back to John Addey (1920 1982), a key voice in bringing Pythagorean understanding of numbers into modern astrology. He wrote Harmonics in Astrology in 1976; it is now back in print after many years. He writes that the number seven (and the 7th harmonic)"is a difficult number to pin down" and "somewhat elusive to interpret."

为了试图给7分相位一个浅显的解释，我找到了历史上的一位占星家，名叫 John Addey ，将毕达哥拉斯对数字的理解带进了现代占星学，他1976年出版了一本《占星中的数字和谐》，书中有关数字7和7分相位，他写道&它是一个很难确定，很难下结论的数字&并且&不太容易解释和捉摸&。

The presence of harmonics in the LO can cause changes in TOI.

劳中存在的谐波会导致印度时报变化。

The more harmonics, the more rich and tonally interesting the wave becomes.

增加的谐频越多，声音就会变得越来越丰富而有趣味。

Reactive power is an important factor of modern electrical power system which always has many harmonics and works with unsymmetrical load.

在现代电力网中，无功功率是影响电网性能的一个重要因素。

To reduce the influence of an unsynchronized sample sequence on FFT and to improve the precision of harmonics in electric power system, this paper improves the algorithm by using windows and interpolation methods.

为了减小非同步采样对快速傅立叶变换的影响，提高电力系统中的谐波分析精度，文中通过加窗和插值对原算法进行了改进。

The result shows that new method can control the input current well sinusoidal, decreases harmonics components, keeps the DC voltage flatted, and provides fairly good fault ride-through capability for the PWM rectifier

结果表明，新的控制方法能使PWM整流器在故障电网下的输入电流正弦，抑制了谐波功率的产生，保证了直流电压的稳定，增强了PWM整流器故障不间断运行的能力。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
