These disadvantages could be eliminated in three-phase systems if the energy account based on the integral of the active power of the positive sequence component with the fundamentalharmonic.
在三相系统中,以正序基波功率的积分作为计量标准,同样可以消除这两方面的不利影响。

The chords the students liked best have frequencies with that harmonic relationship, too - all the frequencies are integer multiples of a common fundamental frequency.
