Under normal circumstances, using a vehicle inside the three-point seat belts, seat belt shoulder strap should be placed on the chest through the site, across the chest of the Central, while the waist is best placed in the abdomen below the pelvis is best placed in the following locations, press live in the thigh, not to suppress the abdomen, so that the calf would not have been caused by oppression, but also to learn to drive on the way to add a security.

一般情况下，汽车里面用的是三点式安全带，安全带的肩带应该放在胸部靠上的部位，穿过胸部中央，而腰带最好置于腹部下方，最好放在骨盆以下位置，压住大腿，不要压住腹部，这样就不会对肚子里的宝宝造成压迫，同时也给学车的途中添加了一份安全。

Pleural calcification was missed by chest film but found in 4 by CT. Pleural effusion was noted in 3 by chest film and 4 by CT. HRCT is superior to conventional chest film in demonstrating the changes in the seconday pulmonary lobule such as focal emphysema, interlobular septa thickness and bronchiolar wall thickness.

胸部x光显示肋膜增厚者10例，CT18例，肋膜钙化者无，CT4例，肋膜积水者3例，CT4例，高解像力电脑断层检查更可显示次级肺小叶內的变化如局部气肿，小叶问隔增厚，小支气管壁增厚，这些均优於传统胸部x光片。

Chest radiography and chest computed tomography showed diffuse multiple cavitary nodules of the bilateral lung fields.

病患的胸部X光片和胸部电脑断层均显示两侧肺部散佈著瀰漫性、多发性的开洞式结节。

Methods There were 100 cases in normal group and 36 cases in group of chest injuries. All cases were performed in volume scan according to conventional chest scan by SIEMENS Sensation 4 MSCT , then performed in thin slice low and high contrast image reconstructions. After that, all the source images were input into CT 3D work stations,costicartilage were imaged by post process software such as multiplanar reconstructions, maximum intensity projection, surface shade display and volume rendering technique. All the pictures were observed and analyzed by two radiologists.

利用西门子Sensation 4 多层螺旋CT机按照胸部常规扫描条件对胸部外伤组36例和对照组100例患者进行容积扫描，然后进行薄层低对比及高对比图像重建，并将重建图像导入CT三维（3D）工作站，利用多平面重建成像、最大密度投影、表面遮盖法成像及容积成像技术对图像进行后处理，由2名CT诊断医生一起对各种后处理图像进行观察和分析。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
