Abstract］ objective to discuss the effect of two kinds of nursing methods of male urinary incontinence patients to urinary tract infection and patient's comfortable influence of degree.methods 80 masculine urine incontinence patients in our hospital with voluntary will were chose,and divided them into the observation group and the comparison group,with 40 examples each.the observation group used bt-ⅰ high level chamber pot,the comparison group used the catheter.compared with 2 groups after nursing of the 3rd,7th,10th,14th day-long urethral meatus bacilliculture,the severance urine bacilliculture result and the urine road junction partial symptom.results compared the results of urine road and severance urine bacilliculture,and the urine road junction partial symptom of two groups,the observation group masculine positive rate was obviously lower than the comparison group,the difference had statistics significance（p.05）.conclusion using bt-ⅰ chamber pot can effectively enhance the nursing effect of the masculine urine incontinence patients'perineum and periphery skin,enhance the patients' degree of comfort.

目的 探讨男性尿失禁患者两种护理方法对尿路感染及患者舒适度的影响。方法本着患者及家属自愿选择的原则将入住我院的男性尿失禁患者80名分为观察组和对照组各40例。观察组利用bt-ⅰ型高级透气接尿器，对照组采用留置导尿管，比较两组护理后第3、7、10、14天的尿道口的细菌培养结果及尿道口的局部症状。结果两组患者尿道口培养结果及尿道口局部不良症状比较，观察组阳性率明显低于对照组，差异有统计学意义（p＜0.05）。结论使用bt-ⅰ型接尿器可有效提高男性尿失禁患者会阴及周围皮肤的护理效果，提高患者的舒适度。

It has been emphatically demonstrated how the forces and moments in every direction of the levitating ring have been calculated from measuring signals. The other parts of the measuring device have been briefly introduced. In chapter 5, according to the symmetrical characteristic of whole model, two similar simplified submodels have been built and described on the coordinate subsystems, and its dynamic state equations have been built.

在分析了高架罐原油挥发气的性能特点及其回收方法的要求以后，提出了通过匹配式多级喷射器利用天然气进行回收的有效途径，并结合两套系统多种工况下的试验结果，给出了以方便工程应用为准则的匹配式多级喷射器的设计管理要领：全压缩比的分配，两级时，第一级约为第二级的 1.4倍；三级时，第一、二级应分别为第三级的 1.8倍和 1.3倍左右；设计点要选择在工作气体参数范围的下限或下限附近；整套系统串联的级数以 2～ 3级较为合适，一般不应超过 4级；在高架罐的耐压范围内，原油挥发气的压力越高对回收越有利

Compared with the traditional positioners, this has many advantages, such asproviding high control accuracy with low air consumption, low energy consumption,self-adjusting, wide application, the ability which can choose the flow characteristicand split range operation. Moreover, it has the function of displaying valve positionand sending alarm signal. At present, HART protocol instruments have wide marketrequirements. And it will play the leading role in the future.
