According to analysis of roots locus,fast excitation tends to decrease damping of power systems which is controlled by AVR than slow excitation.But eigenvalues of power system are far from imaginary axis and strong damping is obtained when fast excitation system is added.

在高放大倍数的AVR控制下，快速励磁较慢速励磁更容易恶化系统阻尼；但是在同时附加励磁控制的情况下，快速励磁可使系统的机电模式根轨迹远离虚轴，机电模式阻尼较大；而慢速励磁下，系统机电模式根轨迹接近虚轴，机电模式阻尼较小，快速励磁优于慢速励磁。

Based on the analysis of the short life of the bearings in the speed increaser of Morgan finishing unit and elastic spacers and breaking of input shafts,the transformation is made to the output and input shaft bearings and the related parts in the speed increaser ,with the good results.

针对高线摩根精轧机组增速机轴承和弹性垫片使用寿命短，输入轴断轴等事故进行分析探讨，通过对增速机输出轴轴承、输入轴及相关配合零件的改造，取得较好的使用效果。

When packing for the valve, the valve packing section and the same space, it is best Preloading Central: When the time for the pump, valve packing and the space section (about 0.3mm-0.6mm) axis and the disk so that there is a leakage of the root space is conducive to lubrication and cooling.

当盘根用于阀门时，盘根截面和阀的空间一样，最好是预压环：当用于泵时，盘根截面和阀的空间(约0.3mm-0.6mm)使轴和盘根有一泄露间隙，有利于润滑和散热。

It was achieved by intradural microanastomosis of the L6 ventral root to S2 ventral root. After axonal regeneration, the "patellar ligament-spinal cord center-bladder" reflex pathway was reestablished. The function of the reflex arc was observed by nerve electrophysiological experiment, detrusor electromyography experiment, urodynamic testing and HRP retrograde tracing before and in 8 months after the spinal cord was destroyed horizontally between S1 and S4 level. There was one case of conical SCI patient who had L1 fracture and paraplegia was received intradural microanastomosis of the L6 ventral root to S2 ventral root after Li fracture and paraplegia.

将Beagle犬L6前根近端与S2前根远端在硬膜内显微吻合，经一段时间的轴突再生后，建立&膝腱－脊髓中枢－膀胱&人工反射弧，术后8个月，在破坏S1~S4脊髓节段前后分别进行神经电生理、膀胱肌电图及尿流动力学和辣根过氧化物酶逆行示踪等检查；对1例L1压缩性骨折伴截瘫患者行右侧T11与52前根经腓肠神经移植硬膜内吻合术。

How to ensure this new structure to be in elastic state under frequent earthqu ake, be mendable under design earthquake and not collapse under infrequent earthquake, especially the last item, is the problem to be solved imminently in engineering field. Center around this problem, 5 aspects of investigation are carried out as following:(1) The experiment of seismic performance of ASCCs in this new frame structure has not been reported, in order to study this problem, 9 ASCC specimens with shear steel plate are tested subjected to the horizontal low cyclic loading, in which, the shear span ratio is 3 and axial compression ratio is different. The hysteretic curves of 9 specimens are obtained. The seismic performance indexes such as energy dissipation, stiffness degradation, strength degradation, skeleton curves and ductility of this kind of column are acquired, and the seismic fortification measures including ultimate values of axial compression ratio under different seismic degree are suggested.

1新型框架结构中所采用的角钢混凝土柱抗震性能的试验研究尚未见报道，针对这一问题，本文进行了9根剪跨比为3、不同轴压比、采用钢板箍的角钢混凝土柱在水平低周反复荷载作用下的试验研究，获得了9根试验柱的滞回曲线，考察了该类柱的耗能、刚度退化、抗力衰减、骨架曲线及延性等抗震性能指标，建议了角钢混凝土柱在不同抗震等级下的轴压比限值等抗震构造措施。

It may be turned by a pulley with a belt or a chain connecting it to a pulley on a second shaft. The supporting structure may be assembled with bolts or rivets or by welding.

一根轴可由联结另一根轴的传动轮的皮带轮或链条轮来带动旋转；支撑结构的组装可用螺拴、铆钉或焊接。

In these devices, one of the shafts is typically driven by a motor or pulley, and the other shaft is driving another device.

在这些装置中，典型的情况是，一根轴由发动机或皮带轮转动，另一根轴将动力传递给其他部件。

The main shaft drives the lay mechanism and is geared to another shaft which operates at half of the speed of the crankshaft.

这样，普通织机应具备两根轴，主轴驱动筘座并通过齿轮驱动另一根轴。

Thus a normal loom has two shafts. The main shaft drives the lay mechanism and is geared to another shaft which operates at half of the speed of the crankshaft.

这样，普通织机应具备两根轴，主轴驱动筘座，并通过齿轮驱动另一根轴。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
