Through analyzing actual harmonic measuring data , studying harmonic management methods , we have contrapuntally managed harmonics in serious polluting district , acquired better effect .
A polyphonic composition in which themes or a theme stated successively by a number of voices in imitation are developed contrapuntally . The song is ended , but the melody lingers on .
Researching on the friction characteristic , establishing the friction model under different velocity , and then taking effective measures contrapuntally play an important role on the motion function of the cylinders.Formerly the research objects about the friction are rubber seal cylinders .
Partial binding can result obvious outline at binding points on the fabric , which is limited in pattern design and production application , and therefore should be contrapuntally selected in product development . 3 .
