ConclutionDTI may be more sensitive in pristine wallerian degeneration of spinal cord compression and can reflact the degree of injury of spinal cord compression.DTI is more precise checking method and can provide valuable information of quantization for earlier diagnosis of spinal cord compression in vivo.

结论磁共振弥散张量成像技术对脊髓受压损伤早期发生的华勒氏变性改变较敏感，并能反应其受压损伤程度，是目前早期活体诊断脊髓受压损伤比较准确的检查方法，对脊髓压迫症能提供有价值的量化信息。

There are some AChR plaques of morphological abnormality, and no contact sites of N-CAM with AChR although the intensity and scope of N-CAM staining is increased.D: Yiqi Huayu Recipe-treated group on the 20th day after L5 nerve root compression. All the AChR sites are reoccupied by N-CAM and the morphology of AChR are restored. E: Untreated group on the 30th day after lumbar nerve root compression. AChR plaques display irregularity in shape, with a few round or spindle shaped cupulae. Meanwhile, some N-CAM stainings are still shown to be around the AChR. F: Yiqi Huayu Recipe-treated group on the 30th day after L5 nerve root compression.

随着时间的推移，AChR斑的形态渐趋规则，N-CAM反应也逐步增强，至造模后20 d达到最高峰，但益气化瘀方组仍然明显优于模型组，其不仅在数值上超过了胚胎期大鼠，且与AChR全部重叠；而模型组仍可见到不少重叠不全且形态异常的AChR斑。L5神经根受压后30 d，N-CAM的表达水平开始下降，基本局限于终板区内，其下降速度和范围在益气化瘀方组明显大于模型组；模型组不仅N-CAM的表达明显高于益气化瘀方组，且仍能见到一些成熟不全的AChR斑；而益气化瘀方组AChR斑形态已接近于正常。

The compression can be achieved by lag screw fixation, a plate tensioning device, or the use of the compression hole of the dynamic compression plate.

这种加压可以通过拉力螺钉，张力带原理放置的钢板，或者应用动力加压钢板上的加压孔来获得。

The disturbing rields caused by the speedup and quietude of upper crustal movement in Tibetan Plateau indicate that, when the upper crust movement is speedup in Tibetan Plateau and keeps the boundary condition unchanged, the energy stored in upper crust is released, the driving force by Indian plate increases the horizontal compression stress and movement in other layers in Tibetan Plateau, and increase the horizontal compression stress in the whole geosphere in North China area Comparing the disturbing distribution of horizontal compression stress in the upper mantle layer, the value in North China area is only about one twelfths of that in south part of Tibetan Plateau.

3青藏高原地区地壳非均匀活动在中国大陆岩石层引起扰动场的研究结果表明，在保持板块边界作用强度不变的情况下，青藏高原地区岩石层上部地壳运动的增强，增加了其岩石层下部的向前推挤，同时也增加了对其它块体的推挤作用，以上地幔盖层内最大水平主压应力的扰动值为例，华北地区比青藏高原南部地区小一个量级。

It is considered that pre-tension stress counteract the compression stress in welding zone generated by thermal expansion, consequently reduce the compression plastic deformation, and depress the tension stress in welding zone when cooling down, and accordingly minish the compression stresses far from the welding zone.

分析认为，预拉伸应力部分抵消了焊接区热膨胀产生的压缩应力，从而减小了压缩塑性变形，进而减小了冷却时焊接区域的拉伸应力水平，相应地远离焊缝区域的压缩应力也随之减小。

Alternatively, the con- trollers can use the synchronous rectifier itself or loss- less inductor current-sensing methods to provide overload protection with lower power dissipation.
