Objective: To provide anatomic data for treating tumors in the posterior and middle tentorial incisural space through comparing anatomic features of the median and paramedian infratentorial-supracerebellar approaches. Methods: 10 formalin-fixed cadaveric specimens were dissected in steps by using the standard median and paramedian infratentorial-supracerebellar approaches under operating microscope respectively.

目的：通过正中和旁正中幕下小脑上入路的解剖学比较研究，为手术治疗小脑幕中和后切迹间隙的肿瘤提供解剖学基础方法：取10例福尔马林固定的尸头标本在手术显微镜下分别模拟正中和旁正中幕下小脑上入路进行逐步解剖，观察和比较不同手术入路所暴露的视野范围，描述重要解剖结构之间的关系。

At an average follow-up of 34.3 months, using the Sports Ankle Rating System, the average clinical rating score was 96.2, the average quality-of-life measure was 96.7, and the average single assessment numeric evaluation was 95.3. Radiographs at final follow-up showed no mortise widening or lateral talar subluxation. Two patients had mild degenerative changes on lateral radiographs with anterior tibial osteophytes.

It has been well documented that the fibular collateral ligament is the primary varus stabilizer of the knee.8,10 Consequently, isolated FCL injuries can elicit abnormal varus knee instability that can lead to functional limitations, a varus thrust gait pattern, and the potential development of medial meniscal tears or medial compartment arthritis over time due to the increased compressive forces at the medial tibiofemoral compartment.16,23,30 In addition, it has been demonstrated that varus instability, primarily due to a deficient FCL from an untreated posterolateral knee injury, causes a significant increase in force on both anterior cruciate and posterior cruciate ligament reconstruction grafts.11,21,22 Therefore, a reconstruction technique to address nonrepairable acute or chronic isolated FCL tears is important to address these pathologic abnormalities.

已经证实腓侧副韧带是防止膝关节内翻的主要稳定结构[8，10]。因此，FCL离断伤可以引起异常的膝关节内翻不稳定，从而导致功能受限、膝内摆步态和潜在发展为内侧半月板撕裂或由于在增加胫股关节间隙的压力会随时间推移发生内侧间室关节炎[16， 23， 30]。此外，已经证实了主要由膝关节后外侧损伤后未经治疗导致FCL功能缺陷引起的膝内翻不稳可以引起前交叉韧带和后交叉韧带重建移植物受力明显[11，21，22]。因此，认为不可修复的急性或慢性FCL离断撕裂伤的重建技术对这些病理异常非常重要。

Electric potential waveshapes of tower body and crossarms were presented by EMTP, also voltage waveshape between upper or lower crossarms and any given phase conductors.

分析结果表明，在高杆塔情况下，降低冲击接地电阻对耐雷性能的改善效果不大；在中横担外侧加设辐合地线和上横担中部增设避雷线以及适当调整导线与上下横担之间空气间隙的距离可有效的改善输电线路的耐雷性能；在条件允许的情况下，建议降低杆塔高度。

The influence of impulse voltage waveshape on particle-initiated breakdown voltage of a GIS system in SF6 and SF6/Air mixtures is reported. The results are compared with the characteristics of air gaps. For the SF6 gaps, breakdown voltage depends on wave-front duration but almost independs on wavetail duration. For the gaps in SF6/Air mixtures, the influence of impulse waveshape also depends on SF6 contents and electrical field non-uniformity

作者研究比较了正极性冲击电压波形对SF_6、空气、SF_6/空气的 GIS 电极装置由固定导电微粒引发的击穿电压的影响，结果表明：SF_6间隙的击穿电压受冲击电压波前时间长短的影响较大，而与波长的关系不大，当采用SF_6/空气混合气体时，则这种影响随SF_6含量增大而愈明显，并与电场不均匀程度有关。

A method is hence proposed to prevent the fault by setting a surge arrester at inlet side of circuit breaker,or setting a surge arrester with gap at line terminal tower if there isn't a position for setting the arrester within substation.

探讨了断路器的性能、现行有关标准和规程的适用性，得出解决故障可采取的措施：在断路器的进线侧安装避雷器，如变电站内无安装位置的话，可在线路终端塔上安装带间隙的线路避雷器。
