Years before de Brosses introduced the term to art criticism, an anonymous music critic called "baroque" the music of Rameau's Hippolyte et Aricie, first performed in 1733, which he found noisy, unmelodious, and capricious and extravagant in its modulations, repetitions and metrical changes.

多年以前，de Brosses引用这艺评的术语，佚名的乐评者称「巴洛克」，是指拉莫（Rameau，法国18世纪音乐家）的歌剧《Hippolyte et Aricie》在1733年首演，他发现这歌剧喧闹、无旋律，转调时过度铺陈，而且变来变去，一直反覆和改变拍子。

Results All the NQs can activate the calcium release channel to some entent and induce Ca2+ transportation.The modulations of 1,4 NQ,1,2 NQ,1,4 NQ2S and 1,2 N are biphasic and depend on their concentrations.The mechanism of gating modulation depends on oxidation and reduction of NQ.The by-products of NQ during oxidation and reduction do not interact with RyR.
