In prophase there existed thermal and magma activity , and before the 其下为一火成岩体隆起带,之下有更深部的热力作用区。

The piedmont , a compressive ground stress area , contains oil / gas pools dominated by structure formed reservoirs 山前为挤压地应力作用区,油气成藏多以构造成藏为主。
To map the regions of trpt1 and pit13 responsible for their interaction with 4 each other , a series of deletions of trpt1 or pit 13 were constructed and examined by yeast two - hybrid 在引出, ” i ”卫与pit13的相互作用中,通过系列缺失方法,证了trpti的功能区(即p门出的作用区位于其氨基酸序列的80 220 。
It is presented that the gas - gushing volume is well consistent to where it is affected by fault through comparing the gas - gushing volume of affected zones to that of normal zones 研究表明,断层作用区与煤层瓦斯高涌出量具一致性;断层落差与最大瓦斯涌出区至断层点的距离具极好的相关性;瓦斯异常涌出范围与断层落差之间也呈现良好的线性关系。
Due to applying double beams , the velocity spread is lower because of smaller influence of space charge compared with single beam mig . in the interaction region this beam is easy to start oscillation and reject mode competition effectively 与单注磁控注入枪相比,双注枪可以提供速度零散小、高束流的电子注,在互作用区更容易起振,且能更好的抑制模式竞争。
A virtual cathode oscillator with an axially extracted te10 or te11 mode based on the tomachan accelerator in our laboratory is investigated using the pic simulation code . the tomachan accelerator can run with an electron beam of 400kev and 8 . 9ka 基于tomachan加速器电子束参数设计的轴向提取te10 / te11模虚阴极振荡器,不需要改变束-波作用区结构,只需通过更换提取波导,即可实现te10 / te11模式微波的轴向提取。
2 . to design an axial magnetic field . the cathode lies in 0 . 4 - 0 . 7 of peak value of the magnetic field and excursion channel in a uniform magnetic field to suppress space charge effects ; to design transition section between the gun and excursion channel in converse computation . 3 选择电子枪阴极处于轴向聚焦磁场峰值的0 . 4 - 0 . 7倍处;漂移通道(互作用区)位于均匀轴向聚焦磁场中,以抑制电子束的空间电荷效应;使用反算法设计电子枪和漂移通道之间的过渡区。
Studies show that the radius of the coaxial l - band bwo can be smaller than that of the non - coaxial l - band bwo . the coaxial bwo of l - band can be very compact and convenient for real application . so investigation on the compact coaxial l - band bwo is of great interest to the high - power microwave field 研究表明同轴相对论返波振荡器可以在相互作用区半径不大的情况下较容易地实现l波段的微波输出,对研制重量轻、体积小的紧凑型l波段返波振荡器有重要的实际意义。
