Among them, the transition metals promoted dearomatization proceed under mild reaction conditions with various substrates, and which could be applied for synthesis of bioactive compounds.

其中，过渡金属参与脱芳构化反应，反应条件温和、反应底物广泛，可应用于生物活性物质。

Then their synthese speed slows down.But the synthese of RNA and DNA inthe follicular cell is continuous during vitellogenesis, which may relate toformation of livetin.

而滤泡上皮细胞卵母细胞卵黄形，RNA和DNA均较快，因此认为滤泡上皮细胞分泌了一些物质参与卵黄蛋白形。
