It was shown that the 3D deformation in the tunnel at soft rock was obvious at F7 fault and phyllite section, with the characteristics of large deformation and longitudinal displacement developing in the opposite direction of work face and being stable at a distance about 2.0 times of tunnel diameter from the work face. And the 3D displacement of tunnels at F7 fault zone developed in an uneven symmetrical way, while there was good consistency for 3D deformation at slate section. Furthermore, there was a mutally verifying relationship between 3D deformation and ground stress distribution of tunnel region.

结果表明，F7断层和千枚岩地段软岩隧道三维位移十分明显，具有隧道大变形特性，其纵向位移背离开挖面方向发展并在相距开挖面约2.0倍洞径时趋于稳定状态；F7断层地段隧道三维位移呈不均匀对称地发展变化，而板岩地段三维位移变化的一致性较好；隧道三维变形规律与隧道区域地应力场的分布存在相互印证关系。

Fault rocks, microstructures and homogeneous temperature (concentrated around 160℃) of fluid inclusions in the quartz veins shows that the fault belt mainly underwent shallow brittle deformation and the highest-grade dynamic metamorphic rock is mylonitized sericite phyllite.

显微构造、断层岩与石英脉流体包裹体均一温度(集中在160℃附近)均显示，断裂带以浅层脆性变形为主，最深动力变质岩仅为糜棱岩化绢云母千枚岩。

Meanwhile, it has more proven this intelligent fault diagnosis method which has merged the advantages of ANN and ES can solve the equipment fault diagnosis problem that faults have pilosity nature, uncertainty and disguise such as the Condensation Equipment. The diagnosis results are precise and credible.

进一步证明了基于神经网络与专家系统结合的智能故障诊断方法能够很好地解决象凝汽设备这类故障具有多发性、不确定性等特点设备的故障诊断问题，其诊断结果精确、可靠。

The shutdown is to pull out the plug-in board-by-block, each pulled out a piece of plate on the boot machine running observation, once pulled out a piece of normal operation after the motherboard, then the cause of the malfunction is the fault of the plug-in board or the corresponding I / O Bus slot and load circuit fault.

该方法就是关机将插件板逐块拔出，每拔出一块板就开机观察机器运行状态，一旦拔出某块后主板运行正常，那么故障原因就是该插件板故障或相应 I/O 总线插槽及负载电路故障。

The core com ponents,including fault location com ponent,time controller,arriving time of directional travelling waves and fault location precision,are analyzed in detail.

就其核心部分——故障测距元件的构成、定时器控制量的选择、方向行波到达时刻的判定以及测量精度的考虑进行了全面的分析，指出了在实现距离测量元件、距离保护段和段中具体的技术关键，提出了有效的对策。

Under the circumstance of simple fault on double circuit transmission lines, the positive-sequence impedance is equal to the negative-sequence impedance, and the positive fault component current is equal to or greater than the negative circuit.

文中通过对线路发生简单故障与跨线故障情况下的正、负序故障分量阻抗关系和正、负序故障分量电流幅值关系的分析，提出了一种判别电力系统发生跨线故障的判别元件。

It either can be started by fault diagnosis, which can assist to make decision after accident, or can be started by static security analysis of the power system, which can be used to make the accident prefiguration and compile the fault preview.
