It was found with SPME-GC-MS method that five green leaf volatiles were emitted immediately from tea leaves after mechanical damage, and (Z)-3-hexenal, (Z)-3-hexenol or (Z)-3-hexenyl acetate were the major volatiles emitted from mechanically wounded tea leaves.
通过SPME-GC-MS测定发现,茶树叶片经机械损伤后均可立即释放5种绿叶性气味物质。 其中(Z)-3-hexenal、(Z)-3-hexenol或(Z)-3-hexenyl acetate的释放量较大。
It is central content of thedissertation how to evaluate mechanical damage that ceramicengender in a grinding process and to set up a grinding modelbased on damage control.
如何对陶瓷材料磨削时产生的力学损伤进行评价,进而建立基于损伤控制的磨削方法,是本文研究的主要内容。
