Second: Comparetive study of ordinary X-ray film, CT and 3D-CT in the jaws fractures. Ordinary X-ray film, CT and 3D-CT was performed in 61 cases of jaws fractures. The diagnosis of these three imaging methods was compared with each other and with the operation findings. The result shows that the fractures in body and angle part of mandibal could be shown excellently by all these imaging methods. 3D- CT is the best method in showing the mandibular fractures. Ordinary X- ray film is poor, and the accuracy of CT and 3D-CT is similar in showing the macxillary fractures.

二。颌骨骨折的常规X线、CT和三维CT对比研究：通过对61例不同类型的上、下颌骨骨折常规X线、CT和三维CT显示情况的对比分析，同时与手术结果相对照，结果表明对下颌骨体部和角部的骨折三种影像学检查均显示准确；对下颌骨髁状突骨折的显示三维CT优于CT和常规X线；对上颌骨骨折的显示常规X线显示较差，CT和三维CT显示准确率相似。

The strength and toughness of the nanocomposites are improved because of the addition of anao-Zno. The volume resistance strength and toughness of the nanocomposites are improved because of the addition of nano-ZnO. The volume resistance coefficient is decreased 8×10 times, surface resistance coefficient is decreased 5.7×10^4 times, and the friction coefficient is decreased 29% by adding nano-ZnO. The friction, wear properties, and the antistatic property of MC Nylon 6/ZnO nanocomposite are better obviously than MC Nylon 6. The macro stress of MC Nylon 6 structure is changed by the tensile test so that the preferred orientation of crystal surface (002+202) is more obvious.

纳米ZnO的加入起到同时增强增韧的作用；使体积电阻系数降了8×10^4倍、表面电阻系数降了5.7×10^4倍、摩擦系数降低了29%，MC尼龙6/纳米ZnO复合材料摩擦磨损性能和抗静电性能明显优于MC尼龙6；经过力学拉伸试验的破坏，引起MC尼龙6结构发生宏观应力变化，造成（002+202晶面）产生明显的择优取向。
