We use mechanics testing method like stretch and bend to test the 3mm magnesium alloy(MB3) after friction stir welding. The stretch sample can show no less than 70% of raw materials performance when the condition is suitable: R= 1500r/min,v = 90mm/min,R/v=16.7 and F=1470N. Curve intensity of the joint reaches 90.2% and 83.0% at obverse and inverse curve separately.

objective to investigate the paregoric effects of butorphanol when the errhysis occurs inside the epidural catheter during continuous epidural anesthesia.methods 60 cases of kidney stones received elective surgery.during this surgery they underwent continuous epidural anesthesia and eight cases of them showed the errhysis in the epidural catheter.then epidural injection of butorphanol was given for analgesia and hr,map,spo2 as well as muscle relaxation conditions were monitored before and 5,10,20 min after injection.the conscious and breathing of patients were also monitored.results before and 5,10,20 min after injection of butorphanol,hr and map difference were not statistically significant.the analgesic results were satisfactory.conclusion butorphanol has a definite analgesic effect when the errhysis occurs in epidural catheter during continuous epidural anesthesia.

目的 探讨在连续硬膜外麻醉中，硬膜外导管内渗血时，应用布托啡诺镇痛的效果。方法择期行肾结石手术患者60例，行连续硬膜外麻醉，其中8例硬膜外导管内渗血，均经硬膜外腔注入布托啡诺镇痛，分别监测注入前及注入后5 、10 、20 min，hr、map、spo2及肌肉松驰情况，同时监测患者神志及呼吸情况。结果注射布托啡诺前及注射后5、10、20 min，hr、map差异无统计学意义，镇痛效果满意。结论在连续硬膜外麻醉中硬膜外导管渗血时，注入布托啡诺维持麻醉镇痛效果明确。
