摘要：地点:巴西东南部3个分枝杆菌参比实验室。目的:评估自动化分枝杆菌生长指示管(m.IT)检测结核分枝杆菌药物敏感性的能力。设计:用自动BEc.Ec.m.IT 960(m.60)对95份结核分枝杆菌临床分离株进行链霉素(Sm.,异烟肼(INH)、利福平(Rm.)、乙胺丁醇(Em.)的敏感性检测,并与BAc.Ec.460 (B460)、比例法(Pm.、抗性比率法(RRm.的检测结果进行比较,其中88株以BAc.Ec.460、比例法、抗性比率法中的至少两种方法获得一致结果作为最终结果,并与m.60的结果相比较。结果:m.60与B460的符合率为95.2%,与Pm.96.6%,与RRm.93.4%;其中与RRm.Sm.符合率最低,与B460在Em.上符合率最低。m.60结果与最终结果的符合率为97.9%, INH与Rm.的符合率为99.2%,Sm.Em.的符合率分别为96.2%和96.9%,m.60报告结果的平均时间为6.9d。结论:与比例法和抗性比率法相比,m.60显示出了极大的优势,并且有助于患者的治疗。

摘要：This work presents the design and c.ntrol of the DAB （dual ac.ive bridge） c.nverter em.loying gyrator＇s theory. A brief sum.ary of the theory is introduc.d, and its applic.tion for the DAB c.nverter is verified with a design exam.le. After that, it develops the c.ntrol and show results of sim.lations and experim.nt. Though the c.m.utation not is studied, the advantage of m.thod is the easy way for projec. and c.ntrol of the DAB c.nverter.
