涡电流分选技术是回收有色金属的关键技术,具有运行成本低、处理量高、无二次污染等优点.磁辊作为涡电流分选机的核心部件,决定了物料的分选效率和回收品位,因此优化其结构参数至关重要.通过建立磁辊的有限元仿真模型,分析了背铁厚度s、磁极厚度d、磁极对数p和等磁辊参数对磁场强度及分布的影响规律;并以磁感应强度和频率的组合参数(B^(2)f)作为涡流力评价指标,优化了磁辊的结构参数.研究结果表明:涡流力随磁辊半径的增加而增加;在磁辊半径不超过148 mm条件下,磁辊的最佳结构参数为背铁厚度20 mm、磁极厚度60 mm、磁极对数8对.

目的:探讨全麻诱导期经静脉输液管(墨菲氏管)给药能否减轻芬太尼诱发的呛咳。创新点:寻找一个简单易行、安全可靠的方法减轻全麻诱导期芬太尼诱发的呛咳。与既往芬成尼和呛咳相关的研究相比,本研究试验组操作不仅简便、快速,而且无需额外使用其它药物或设备,不增加人力成本或病人经济负担。方法:择期行全身麻醉手术1138例,所有患者均采用咪达唑仑-芬太尼-丙泊酚-顺式阿曲库铵-气管插管麻醉,随机分为静脉输液管缓慢滴注组(S组,573例)与经三通快速输注组(C组,565例),记录麻醉诱导期两组患者呛咳发生率及严重程度和其它不良反应发生情况。结论:静脉输液管缓慢滴注组呛咳发生率及严重程度较快速输注组明显降低,其它不良反应发生率比较差异无统计学意义。全麻诱导期经静脉输液管缓慢滴注芬太尼可明显降低该药所致呛咳的发生率,且该法简单易行、安全可靠,值得推广。
