MRI characters mainly were that amyotrophy attenuated muscle and muscle outline collapsed;intramuscular adipose heterogeneitily infiltrated,which resulted in MRI signal heterogeneitily raising up and the ratio of lumbar subcutaneous fat MRI signal to lumbar dorsal muscle MRI signal descending;intramuscular spatia was revealed as line-lamellar form or featheriness or grid grid form.

Results all of the 20 x-ray cases demonstrated the trabeculae bone hazy with pathy high density in the weight-supporting zone .all of the ct cases demonstrated the collapse of the femoral head. and the 4 cases demonstrated the high density, fragment of the femoral head and cystic lucency zone in the high density area and mixed density could be seen in 3 cases. the 4 mri cases demonstrated cystic hypointensity in t1wi and hyperintensity in t2wi. the 3 mri cases demonstrated mixed intensity in t1wi and t2wi,the 3 mri cases demonstrated irregular hypointensity with collapse of the femoral head in t1wi and t2wi.

结果 x线平片20 例，均表现为股骨头持重区骨小梁增粗且模糊不清，持重部位呈斑片状或斑点状密度增高影，本组均可见（占100%）。ct扫描20 例，平扫均表现为股骨头形态塌陷，其中显示高密度硬化4 例（占20%），股骨头碎裂，显示高密度区内有不规则透亮区，呈高低混杂密度改变有3 例（占15%）。mri扫描10 例， t1wi呈斑点状或小囊状低信号，t2wi为高信号，本组4 例，t1wi与t2wi均为不规则低、等、高混杂信号，本组3 例，股骨头塌陷、变形，t1wi与t2wi均为不规则形低信号3 例。

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 results show that the influence of electromagnetic stirring on the following solidification behavior is more outstanding when the stirring temperature is near the liquidus; the number of α dendrites is declined and the morphology is transformed into rosiness and non-dendritic grains; the Al-Si eutectic's transition from lamellar structure to fibrous structure occurs in the eutectic reaction too.

结果表明：随着搅拌温度的降低至液相线附近时，电磁场对熔体凝固行为的影响逐渐显著；α初晶中树枝晶不断减少并逐渐转变蔷薇状晶和非枝晶；水淬后Al-Si共晶组织也由粗大的片层状转变为细小的纤维状和鳞片状结构。

The results showed that it is more difficult to demulsify for the emulsion of reacted acid and crude oil.

Gravure press is not discharge on down during the mode of production, the per-color business card printing and membership card after harvest cylindrical insertreleased, offline after the subject with a single eyefor a cross-cutting machine rolled business card printing and membership card making for easier and more precise printing long broken sected collection, and then set the broken sected collected leaflets business card printing and membership card making products in spinons convex, indentation, die-cutting, waste, collection, testing, packaging; business card printing and membership card making products for stamping or compact label positioning easy-care, and the increase in the operation, the disadvantage is that the above process, the operation covers an area of large plant, to make more, and sometimes the drum to the materials offline operation in cross-cutting precision |interrupted Zhang superstandard, it will be a large number of categorizing people and a large area of the workspace.

凹印机是采用上料下料不停机的生产方式，进行逐色制卡和会员卡制作后收成卷筒状取下，离线后通过一台识标横切机把卷状制卡和会员卡制作品以单幅印长断切收集，再将断切收集来的单张制卡和会员卡制作品进行棘凸、压痕、模切、剔废、收集、检验、包装；制卡和会员卡制作品如需要烫金或镭射标定位烫，还需增加工序，以上工艺缺点是工序多，占地面积大，使用机台多、人员多，有时卷筒印材离线作业在横切过程中断张精度超标，还需大量的分检人员和大面积的工作空间。

Results:The main radiological manifestations of the interface of peripheral cancerized gastric ulcer are: Small segment with prominent, regular margin, clubbed plica, slim plicae reaching the margin of the niche or margin of the small segment of are prominent. The radiological presentations of gastric cancerized ulcers are mainly tortuous large plicea and slim striped plicae, and the pathologic changes under microscope are mainly chronic superficial gastritis.
