This deviation from perfect sinusoids is usually expressed in terms of harmonics distortion of the voltage and current waveforms.
这种偏离完全正弦的畸变称为电压、电流波形的谐波畸变。The case of a harmonic oscillator driven by sinusoidally varying force is an extremely important one in many branches .
在许多领域中受正弦变化力策动的谐振子是一种十分重要的运动。Signals with sinusoid modulated phase is the general form of micro-Doppler signals in radar echoes from targets with micro-motions.
正弦调制相位信号是微动目标雷达回波微多普勒信号的一般形式。Fast and accurate computation of the arcsine function in a modern engineering has been used widely.
快速精确的反正弦函数运算在现代工程中应用广泛。We start with a simple sine curve and customize it to look just as we want it to.
我们从简单的正弦曲线开始，将其定制为我们所希望看到的形状。Its output sine signal needs to be converted into the same frequency square TTL signal received by the controller shown in Fig. 2.
它的输出正弦信号需要转换成相同的频率平方米的TTL信号控制器收到的显示图。2。Different from other manufacturers, SINEE determined its global strategy based on self-owned brand since the beginning of its establishment.
与国内其他企业不同，正弦电气一开始就确定了要做自主研发生产、自主品牌的国际化战略路线。However, it is possible to achieve the sinusoidal back EMF waveform at the small pole-arc to pole-pitch ratio.
但是，它可以实现在小极弧极间距比正弦反电动势波形。Fatigue life of random vibration can be calculated by the fatigue life of sinusoidal vibration under first natural frequency.
可以通过一阶固有频率下正弦振动试验试件寿命得到随机振动下试件的寿命。
