The pleural superficial blood vessels were smooth, while the round imprints of endothelial nuclei along the vascular axis and circular constrictions were found on the subpleural arteriole and the terminal arteriole.

胸膜面浅层的微血管铸型表面比较光滑，胸膜下微动脉和终末微动脉表面可以看到沿血管长轴排列的呈圆形的内皮细胞核的压痕，以及规律分布的环状缩窄。

In this Paper analysis several different complexity of the river network, found that the more complex the river network, laid on the location of the observation points higher demand,and theannular network high sensitivity than the treelike network in the Observation points layout.

论文中分析了几个不同复杂情况的河网，发现对于越复杂的河网，对观测点的布设位置要求越高，环状河网的对监测点空间布置的敏感性比树状河网高。

The round-link chain as a driving chain can always adapt to such a break, due to its vertical and horizontal articulation at that specific location.

环状连接链作为一种强劲的链状组织总是能适应这样的中断，因为它的垂直和水平的关节在那个特殊的位置上。

Some marking things are very and far apart from mutually, usually brushing past some copings of low and short buildings from the different directions, from very the distance can can see, becoming inside a wreath form district of according to thing, the sharp crest of the mansion or the 孤 tower of the top of hill.

有些标志物相距甚远，通常从不同的方位，掠过一些低矮建筑物的顶部，从很远处都能看得见，形成一个环状区域内的参照物，大厦的尖顶或山上的孤塔。

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。
