The main research contents and results are given as follows:(1) Principles and characteristics of different types of polarization controllers are analyzed, the compare of the difference of these polarization controllers are discussed based on them, drawn a conclusion that the polarization controller which based on squeezing fiber and has variable delay quantity are suitable for high speed optical communication system.(2) The reset principle of the typical four channel polarization controller which is based on squeezing fiber is analyzed, and the design of its concrete reset scheme is given based on them. The reset process and the corresponding operation list are given in detail.(3) The systematical experiment is made when the typical four channel polarization controller is put into the PMD compensator. The experiment result showed that the channel which needs reset can efficiently return to the mean place, and the effect of reset was good, it didn't cause any badness infection on PMD compensation.(4) A new type optical signal time-domain depolarizer is given, and a new PMD compensate method is given based on it.

Reset circuit so that it is in normal power supply and clock time to do so have a signal, all the motherboard does the reset signal is sent to the South, then we look at the reduction and whether it is normal, one can test the related equipment to test the reset point, to see if it has an instant change of the voltage jump, the second is to look at testing the reset card instant flash of light, under normal circumstances, it is the flash, if that does not shine or Always represent abnormal.

复位电路呢，它是在供电和时钟正常的时候呢产生的一个信号，主板上的所有这个复位信号呢，都是由南桥发出来的，那么咱们看这个复位是否正常，一是呢测这个相关设备的这个复位测试点，看它是否有瞬间的电压跳变，二是看测试卡上的复位灯瞬间闪一下的，正常情况下呢，是闪一下，如果说是常亮或不亮都代表不正常。

According to the criteria of Matta radiographicgrade,there were 18 cases with anatomic reduction, 9 with satisfactory reduction,3 with unsatisfactory reduction and 4 with joint contour reduction.

根据Matta 影像学评分，解剖复位18例，复位满意9例，复位不满意3例，4例关节轮廓复位。

The manual reset input allows other reset sources, such as a manual reset switch, to generate a processor reset.

手动复位输入允许其它的复位来源，比如利用手动复位开关产生一个微处器复位。

Methods:Twelve patients with fresh transverse fracture of patella were reviewed in the study.The hemarthrosis,blood clot,fracture fragments and soft tissues between them were cleared with arthroscopy.With the help of C-arm X-ray,the fracture was reduced with manipulation method.After the articular facet reached anatomical reduction,two Kirschners were inserted percutaneously from proximal end to distal end of fracture to fix the fragments,Two hollow screw were put along the approach of Kirschners,and tension band fixation was performed with the shape of "8".Results:All the patients were followed up averagely 12.4 months.

12例新鲜髌骨横骨折患者通过关节镜清理关节腔内的血凝块、碎骨块和骨折块之间嵌顿的软组织，直视下观察骨折复位情况以指导骨折复位固定，在C形臂X线透视下帮助骨折复位，关节镜观察关节面解剖复位后，经皮从近折端向远折端平行打入2枚克氏针固定骨折块，顺克氏针拧入2枚中空螺钉，拔除克氏针，顺螺钉空心导入钢丝，行张力带&8&字固定。

As a whole the effective assess ment index of intraoperational monitor had been established, providing reference for the lumbar spondylolisthesis surgery.Taking the SEP index value of postanesthetic patients before operation as the standard, the changes of intraoperational potential may indicate the following status: The latency period decreasing in 10%-15% or the amplitudes increasing in 40% indicated that the outlook of recovery was good enough and the prognosis was favoured.The latency period decreasing in less than 10% or the amplitudes increasing in less than 30% indicated that part of the function could be reduced.

以患者术前以及麻醉后的SEP指标值为基础，术中监测电位指标变化表现形式：①滑脱复位后，若潜伏期缩短10％～15％或波幅增加＞40％，提示预后良好；②监测电位指标平稳，或潜伏期缩短＜10％，或波幅增加＜30％，可继续完成复位，术后可有部分功能恢复和症状改善；③在复位过程中，监测电位指标出现暂时性波动，可在15～20min内恢复到基础电位，应在电位出现波动时停止复位，术后仍可恢复部分功能和改善症状。

If by means of a prereduction MRI or after neurologic deterioration during closed reduction, the surgeon becomes aware of a fragment of disc material displaced into the spinal canal, then an anterior discectomy, open reduction, fusion, and plating becomes necessary.2,7,9 In approximately half of the cases, a closed reduction will be successful in reducing the dislocation before surgery.50 In the majority of the others, an intraoperative reduction performed after the discectomy and decompression will achieve anatomic reduction.9,51 For those patients in whom an anterior discectomy and decompression have not been successful in reducing the dislocation, then a supplemental posterior open reduction should be performed.52

假如借助MRI检查，或在闭合复位过程中神经症状进一步加重，外科医生意识到有椎间盘碎片突入了椎管，此时就需要前路椎间盘切除减压、开放复位和固定融合。大约有一半的病例手术以前能够通过闭合复位来成功的将脱位复原，剩下的病例则需要在术中将椎间盘切除减压来达到解剖复位。假如有病人经过前方的椎间盘切除和减压后仍然不能成功的还原脱位，则需要再行后方的开放复位术。

The excellent and good rate for clinical and roentgenographic results were 65.3% and 67.2% respectively.

结果解剖复位12例（57.1％），复位满意5例（23.8％），复位不满意4例（19.1％）解剖复位率在最初和最近6年手术组分别为44.4％和66.7％。

For supracondylar fracture of humerus with obvious displacement,it is easy to make reduction,but the fixation and the maintenance of reduction is not easy; manual reduction with plaster or splint immobilization,though as the first-chosen method,has such shortcomings as infirm or loosening fixation of plaster or splint which may cause injury to blood vessels or nerves; open reduction may lead to further trauma to soft tissues and tissue adhesion,and to joint stiffness; the closed reduction with cross Kirschners wires under C-arm X-ray can avoid the above mentioned shortcomings and it is easy in operation.

移位明显的肱骨髁上骨折，复位容易，但固定及维持复位困难，手法复位石膏或夹板外固定虽是首选治疗方法，但石膏或夹板固定不牢固，易出现松动甚至可造成血管及神经损伤，而切开复位更易进一步造成软组织创伤，组织粘连，最终导致关节僵直功能障碍。本组C臂下闭合复位交叉克氏针治疗移位明显的肱骨髁上骨折避免了上述缺点，而且方法简单。肱骨髁上骨折；经皮克氏针固定；儿童；闭合复位
