Methods: The muscular branches originating from the three parts(radial tunnel part, supinator tunnel part and post-tunnel part) of PIN were observed on 30 sides upper limb specimens.The dimensions and morphology of the radial tunnel, supinator tunnel and the arcade of extensor carpi radialis brevis muscle were observed and measured with caliper, and the surface projection of the entrance and exit of the ST were located.

30侧尸体上肢标本，将PIN分为3段(即桡管段、旋后肌管段和旋后肌管后段)观察其肌支的分支情况；用卡尺对桡管、旋后肌管和桡侧腕短伸肌腱弓的形态和大小进行了观测，并对ST入口和出口的体表投影定位。

On the other hand, after the reformation the unit specific energy consumption decreased 10 kilogram equal normal fuel oil per ton raw oil. In this paper, author analyse the principle and the advantages of the two stage riser fluidize catalytic cracking technology, where catalyst flow in relay and react in section, and short contact time and high c/o ratio. This paper propose a new method to calculate the catalyst circulation rate in each riser of a two stage riser fluidized catalytic crack unit and find out that the c/o ratio is lower than it should be by calculation use this method and give a suggestion to solve this problem.

Conclusion1 Critically ill patients with indwelling catheters were of the high positive rate of microorganisms,and microorganism spectrum was of special properties;BF formed mainly inside the catheter,the occurrence rate of BF inside the catheter was high and the formation time was short;Changes on catheters and the result of microorganisms was positively correlated with the BF formation.2 Indwelling catheter time was the independent risk factors for the BF formatiom, while age、APACHEⅡscore、sex、urine sugar and the types of antibiotic usage were the potential risk factors for the BF formation;Nurses should perfect the catheter measures for critical ill patients,emphasis on the assessment of risk factors of BF formation,and implement special care in high-risk patients.3 In the early stage of BF formation,irrigation could play the role of eradicative BF effectively;While later,it couldn't,but it can delay the speed of BF formation and maturation;In the choice of washing methods,injection type washing method is superior to infusion.

结论1重危患者留置尿管微生物培养阳性率高，且微生物菌谱具有特殊性；重危患者尿管表面BF主要在尿管内壁形成；内壁BF的发生率高，形成时间短；肉眼观察尿管表面改变情况以及微生物鉴定结果与BF形成呈正相关。2尿管留置时间是重危患者留置尿管表面BF形成的独立危险因素；年龄、APAcHEⅡ评分、性别、尿糖定性以及抗生素使用种类是其可能的危险因素；护理过程中应完善重危患者尿管护理措施，注重对BF危险因素的评估，并对高危患者实施重点护理。3 BF形成早期，冲洗能发挥较好的清除作用；BF形成后期，冲洗无法彻底清除尿管表面BF，但冲洗能延缓BF形成与成熟的速度；在冲洗方式的选择上，注洗式冲洗法对尿管BF的清除效果优于输注式冲洗法。

The major concentsare summarized as follows: 1.Experimental research on the GFRP Tubed short reinforced concrete columns underaxially loaded are carried out to investigate the mechanical properties of working feature, theeffect of GFRP tube confining,ductility of the specimens.The effects of concrete strength,loading condition,ratio of longitudinal reinforcement and ratio of stirrups are researched.

objective to evaluate clinical effect of the handling protaper nickel-titanium rotary instruments in preparation of canals of posterior teeth.methods 96teeth with pulpitis or periapical periodontitis were instrumented by handling protaper rotary instruments using step-down technique,and by k files using step-back technique for control.all teeth were obturated with lateral condensation methods.the efficiency of preparation was analyzed with ra-diographs before and after operation.results no transportation,apical blockage and ledge were found in test.the technique could keep canals smooth.there were two ledge,one instrument fracture and nine transportation in control.the operative time was shorter and post treatment pain seldom occurred in handling protaper group.conclusion the handling protaper niti rotary instruments can prepare the canals effectively and safety.after the preparation,the canals could be easily washed,sterilized and filled.it is an efficient instrumentation method for posterior teeth's canals and be used widely.

目的 评价手用protaper预备后牙根管的临床效果。方法选取患有牙髓炎和根尖周炎的后牙96例，随机分成试验组和对照组各48例，试验组用手用protaper多锥度镍钛旋转器械逐步伸入法预备根管，对照组用k锉，逐步后退法预备根管，两组均用侧向加压充填法充填根管，根据治疗前后的x线片，评价后牙根管预备效果。结果试验组无根管偏移、根尖阻塞、台阶，且根管壁平滑流畅，无器械折断等并发症发生。对照组有2例台阶形成，器械折断1例，根管偏移9例。试验组操作时间短且术后疼痛轻微。结论应用手用protaper预备后牙根管快速、安全，成形效果好，易于根管冲洗消毒及填充，可视为临床上预备后牙根管的有效方法。
