结果表明：方波和正弦波调幅磁场的感应热功率都与调幅波频率无关。

The results show that the induction heat power of magnetic field amplitude-modulated with sine wave and square wave is unrelated to the frequency of modulating wave.

本文讨论了调幅系数为任意值的调幅波，给出了它的表达式、频谱及调幅系数、调制效率和信噪比增益的计算公式。

The amplitude modulated wave with any modulation factor is discussed in this paper. Its expression, spectrum and formula of the modulation factor, modulation efficiency, SNR gain are given.

言语若采用经调制后的方波或调幅波传递，将会获得满意的可懂度。

With square wave or amplitude modulating wave transmission, the speech communication will have satisfactory intelligibility.
