Then the element equation and unit tangent rigid matrix are deducted on the basis of description of UL coordiate and principle of imaginary, the balance equation and overall tangent rigid matrix are integrated via introduction of terminal condition, and the nonlinear equation group is finally parsed on the basis of combination method of Newton-Raphson and increment.

接着基于U.L 坐标描述，从虚功原理出发推导出单元的平衡方程和单元切线刚度矩阵，引入边界处理条件集成了整体结构的平衡方程和总切线刚度矩阵，并采用Newton—Raphson 法和增量法相结合的方法求解非线性方程组。

150HP-300HP screw air compressor rotor is the German GHH-RAND joint shaft type unit,adopts the third generation asymmetrical dentate 5:6 rotors,The major axis is more reasonable than the choice, the tangent speed of rotors is only 30-36m/s, is far lower than that———60m/s of common air compressors, it keeps 0.003INCH between rotors that will not abrase forever, the space between teeth dropping variance is small, so the backflow loses is slight, Enhances10-12% kf the efficiency compared to the 4:6 dentate, save power 20%, adopts the Swden SKF bearing.

150HP-300HP）螺杆机转子为德国GHH-RAND联轴式机组，采用第三代非对称齿型为5：6的转子，长径比选择合理，其转子的切线速度仅为30'36m/s，远低于一般空压机60m/s 的切线速度，转子之间保持0.003INCH间隙永不磨损，齿间落差小，故回流损失小，比4：6齿型提高效率10-12%，省电20%，采用瑞典SKF轴承，极大延长了主机的寿命。

Methods A retrospective analysis of paranasal coronal computedtomography scans of 200 sides from 100 patients were performed. The junction point between vertical line of orbital plate and anterior cranial fossa, the angle from the line between the above point and attachment point of cribriform plate to horizontal line, the distance from vertical line of orbital plate to attachment point of cribriform plate, were measure respectively.

回顾性分析100例患者200侧的鼻窦CT，在冠状位上测量眶板垂直切线与前颅底交点，此点与中鼻甲骨质筛板附着点的连线与水平线的夹角、眶板垂直切线与中鼻甲骨质筛板附着点之间的水平距离。

Everyone was required to lake a full-length standing X-ray film of the lower extremity. The hip-knee-ankle angle, femorotibial angle and tibial plateau-tibial shaft angle were measured on their anteroposterior radiographs. while the posterior slope of tibial plateau was measured on their lateral radiographs based on three reference lines: anterior tibial cortex tangent line, tibial proximal anatomical ink acid posterior tibial cortex tangent line.

受试者拍摄下肢站立位全长X线片，并按要求测量髋－膝－踝角、胫股角和胫骨平台内翻角，再分别用胫骨中上段前侧骨皮质切线、胫骨中上段轴线和胫骨中上段后侧骨皮质切线作为参考线测量胫骨平台后倾角。

The method of slope deflection entails writing two equations for each member of a continuous frame, one at each end, expressing the end moment as the sum of four contributions:(1) the restraining moment associated with an assumed fixed-end condition for the loaded span,(2) the moment associated with rotation of the tangent to the elastic curves at the near end of the member,(3) the moment associated with rotation of the tangent at the far end of the member, and (4) the moment associated with translation of one end of the member with respect to the other.
