High oxygen isotope temperatures of 650 to 695℃ were obtained when pairing quartz with such resistant minerals as garnet, zircon and kyanite, suggesting that the refractory minerals have preserved their oxygen isotope compositions acquired during eclogitization and only suffered much weaker retrograde metamorphism than the other minerals in the eclogite.

石英-耐熔矿物对氧同位素温度主要集中在650～695℃之间，表明耐熔矿物石榴石、锆石和蓝晶石在该区榴辉岩中相对其它矿物来说保存最好，退变质作用最弱，因此其氧同位素温度与峰期超高压榴辉岩相变质奈件基本一致。

Multiple-paths hydrogen abstraction reactions of fluorine -with CH_3OH have been investigated at the MP2/6-311 ++ g level. The potential energy surfaces for H-abstraction reaction from carbon atom and oxygen atom were given respectively. The results indicate that there is only one minimum energy path for hydrogen abstraction from carbon atom, while multiple paths were found for hydrogen abstraction from oxygen atom. All the stationary structures, frequencies as well as PES sketch of all channels were given, in which the dominant channel is by a five-member ring transition state. The calculated heat of reaction is 170.62 kj/mol for channel 1, 119.41 kJ/ mol for branch channel 6. The results are in good agreement with experimental data.

以MP2/6-311 ++g水平上详细研究了氟原子与甲醇抽氢反应的多通道反应机理，得到了各条通道中涉及的驻点的构型和振动频率及其能量，给出了两张完整的反应势能面，结果表明，氟原子从C原子上抽氢时有一条明显的最低能量通道，而从氧原子上抽氢时要涉及多条分支通道和多个驻点构型，给出了各分支通道势能面示意图，结果表明以形成五元环状过渡态通道为优势通道，计算得到经途径1生成CH_2OH时反应放热170.62kJ/mol，经分支途径6生成CH_3O自由基时反应放热119.4 kJ/mol，此结果与实验值一致。
