AIM: The incidence of malrotation after femoral shaft fracture treated with close reduction and interlocking intramedullary nailing is high. To judge the degree of rotational deformity in fracture of shaft of femur by C-arm X-ray machine is necessary in the repair of tissue construction.

目的：采用闭合复位带锁髓内针置入固定治疗股骨干骨折，术中常出现远端旋转畸形，利用C形臂X射线机并以健侧NH角（股骨头－颈轴线与水平台面的夹角）作为参照物，判断骨折端旋转移位程度是组织构建修复过程中必须解决的应用技术。

Nodal and Activin, members of TGF-βsuperfamily, are mediated by the TGF-βreceptors ALK4 or ALK7, and they play important roles in mesendoderm induction and anteroposterior patterning of the neuroectoderm.

TGFβ家族的信号转导由TGFβ受体ALK4或ALK7介导，在脊椎动物胚胎的中胚层和内胚层诱导以及神经外胚层的前-后轴线分化中起着重要作用。

Then the model is modified, considering the effects of irregular entrainment interface on the top of IBL, and applied to fumigation dispersion over Nanticoke coastal area.

然后考虑混合层顶不规则夹卷界面的作用，应用于楠蒂科克沿岸陆上熏烟扩散问题，将模拟的地面轴线浓度与观测资料以及三个熏烟扩散预测模式的结果作了比较。

We know that taping refers to the business card printing and membership card when dot shape or the occurrence of nonanatomical monlchamus film thickness changes in parallel business card printing and membership card making drum axis formed by the ink of depth.

我们懂得，杠子即指在制卡和会员卡制息时网点轮廓或不朱膜厚度爆发不法规保持，在交错制卡和会员卡制息滚筒轴线标的目的所变成的不朱色深浅纷歧的条痕。

RESULTS AND CONCLUSION: The cervical three-dimension images were reconstructed clearly with the CT three-dimensional reconstruction techniques. The cervical pedicular width, the axial length,α and β angles were measured by the soft measure function.

结果与结论：应用CT三维重建技术可以获得清晰颈椎三维图像，使用软件测量功能可精确地获取预置螺钉的椎弓根管宽度、轴线长度、α及β角；在颈椎椎弓螺钉置入情况下，可测量置钉的水平角度安全范围。

Methods Thethree dimensional quantitative anatomy of thoracic spine pedicular was determined by 10adults dry thoracic spine specimens,20 X rays pictures,20 MRI and CT pictures usingVernier caliper,the pedicular included the height,the width,the length,the axis angulationof the pedicle,the point of screw penetration,the width of two pedicles,the adjacent topedicle and so on.

用游标卡尺对10具成人T1～11椎体干燥标本、20份X线片、20份MRI和CT片的椎弓根高度、宽度、长度、进钉点定位及椎弓根轴线的角度、椎弓根之间的宽度、椎弓根的毗邻等进行观测。

Experimental investigations on pulsant behaviors of particle flow were carried out on a two-dimensional spouted bed using PIV .

本文基于 PIV 处理颗粒流动图像获得了颗粒流动的瞬时速度；基于功率谱密度分布对瞬时速度的分析结果表明，喷射区轴线的中下部颗粒存在较强的速度脉动，环隙区颗粒速度脉动较弱；研究发现喷动周期与床体压力脉动周期基本一致。

The cartridge ( 2 ) is removably mounted and rotatably adjustable about an axis of rotation ( 17 ) between a first position for allowing no or little air to pass through and a second position for allowing more air to pass through than in the first position.

该筒(2)可拆卸地安装，且围绕旋转轴线(17)在用于允许极少或者不允许空气通过的第一个位置和用于允许比在第一个位置多的空气通过的第二个位置之间可旋转地调节。

The shape formed by projection of correlation line of rotative surface on which two axises Intersect by meahs of analytical method is discussed,and some related characterlstles of hyperbolic curve ,on the basis of which are given some ideas about making a drawing by correlationline projection are analysed and the actual drawing process is illustrated.

用解析法探讨了两轴线相交的回转面的相贯线投影的形状，分析了双曲线的一些相关特性，在此基础上给出了相贯线投影作图的新思路；利用实例说明了具体的作图过程。

Set out the axis line and border lines for shuttering.

放好轴线和模版边线。

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。
