Results showed that the polyphenoloxidase was activated when the high pressure treatment on the pear juice was carried out under the temperature 50 ℃,the dwell time 10 min,the pH5 and the pressure between 200～300 MPa.

实验结果分析表明：在处理温度为50℃、保压时间为10min和梨汁pH值为5的条件下，200～300MPa处理梨汁时多酚氧化酶被激活，活性表现最高；500MPa时酶的活性下降到75.3%。协同温度为30℃处理梨汁时，酶的活性反而增大；30℃以后，酶活性随温度升高而迅速降低；有效协同高压处理的温度为40℃。

While laybacking up the lower section of the crack, I concentrated on conserving my energy by climbing as fluidly and in as relaxed a manner as possible. I felt surprisingly strong through the first series of difficult moves, but as I began to execute one of the last ones, my timing and body position were slightly off. As I tried to thrust my finger tips into a small undercling slot, my foot popped off and I suddenly found myself dangling 2000 feet above the ground.

在裂隙下面部份要layback上时，我专注的尽量流畅和用放松的方法来节省体力，我觉得自己好像惊人的强壮爬完第一个连续难点，但当开始爬最後一个时，我的步调及动作有点不配合，我试著强把指尖放进一个小倒拉缝时，脚砰的滑掉，突然觉得自己在距地面二千英尺的地方摆荡。

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。
