This study was designed to evaluate the effect of tracheal topical anesthesia using EMLA? Cream (EC) coated on the endotracheal tube (ETT) with or without epidural anesthesia (EA) on isoflurane requirement during general anesthesia (GA) and investigate whether EC coated on the ETT with EA was associated with the additive effect compared with the effect when each anesthetic was administered independently. The prospective randomized, double-blinded, and controlled study included 60 ASA I–II patients scheduled for upper abdominal surgery requiring GA. Patients were randomly assigned to one of the following groups: group 1 received GA, group 2 received EC+ GA, group 3 received GA+ EA, and group 4 received EC+ GA+ EA. Isoflurane was administered at the required concentrations to maintain the mean arterial pressure at a level not exceeding 20% of preoperative values. The percentage mean expired concentration (%MEC) was used in calculating the isoflurane requirement. Emergence agitation, postoperative sore throat, and hoarseness were recorded. Groups 2, 3, and 4 exhibited a significant reduction on isoflurane requirement compared with group 1 (P<0.05). The isoflurane requirement evaluated by %MEC decreased by 12%, 38%, and 50% in groups 2, 3, and 4, respectively. The incidence of emergence agitation was significantly lower in groups 2 and 4 than those in groups 1 and 3 (P<0.05). Tracheal topical anesthesia using EC coated on ETT with or without EA reduced the isoflurane requirement during GA, indicating that EC combined with EA exhibited an additive effect on the requirement of general anesthetic.

在工程全生命周期中,工程管理信息化规划与实施过程涉及组织的战略管理和项目管理两个层面,匹配问题是工程管理信息化过程中的核心问题之一。在战略管理层面,首先要充分明晰工程的信息处理需求,进而根据需求确立信息系统规划的目标;在项目管理层面,工程信息处理能力的形成不是工程参与各方能力的简单叠加,而是其能力相互匹配的结果,匹配程度的高低决定了工程的整体信息处理能力的高低。更进一步,工程信息处理能力与工程信息处理需求的匹配程度决定了工程管理信息化水平的高低,同时也会对工程的整体绩效水平产生影响。

上个世纪末,我国饲料工业总产量比改革开放前增长了近70倍。1999年全国配合饲料合格率也从20世纪80年代的40%~60%提高到95.7%,这是一个巨大的成就。但目前饲料工业标准化工作则相对滞后。入世以后,我国饲料工业标准化体系将面临着与国际质量管理和质量保证标准的接轨以及与环境管理系列标准的配套问题。为此,在近期内应把握时机,及时作好我国饲料工业标准化工作水平的提高及更新换代。当前应重点抓紧饲料安全性标准的增删与修订。对饲料卫生标准、饲料原料标准、饲料质量监测技术及生物学效价评定等方面的标准必须全国统一;而对饲养标准则应因地制宜分类设置,根据具体情况可以跨省区设一类饲养标准,也可以在一个省或区设多种类型的饲养标准。
当前,饲料市场各个流通环节中的法制建设任务仍然十分艰巨。要坚决杜绝一切有损社会、生态效益的饲料添加剂进入市场;特别要严密监视国外活菌制剂类饲料及一切激素类饲料添加剂非法进入我国市场。要加强保护我国目前尚保留着的大面积净土;要为合法的、科学的饲料添加剂正名。这是争创“中国产绿色产品”品牌,提高我国饲料工业产品市场竞争能力的重要保证。

A new pipe rupture valve for hydraulic elevator is designed. Mathematical models established for the hydraulic elevator system are used in numerical simulations on the Simulink environment of Matlab kits. The effects of different viscous damping diameters, inlet pressures of pipe rupture valve, and elevator loads on the hydraulic elevator system s dynamic performance are analyzed. Experimental research is also carried out using a hydraulic elevator experiment rig. The numerical simulations accord with experimental results in general. Dynamic performance indexes are assessed by the EN81-2 standard. The results show that the newly designed pipe rupture valve meets the designing requirement for hydraulic elevators.

在网络带宽受限的网络控制系统中,设计了一个基于一维输入输出映射关系的模糊逻辑调节器,对 控制系统的带宽进行动态管理。通过调整该模糊逻辑调节器中的非线性偏移因子可以进一步改善系统的控 制性能和带宽需求。同时利用线性矩阵不等式及资源受限条件来确定带宽动态分配的上下界来保证系的 稳定性。另外,定义了多回路归一化控制质量和归一化带宽需求度性能衡量指标来评价网络控制系统的全 局性能。在此评价方法下,提出的模糊带宽管理方法和采用固定带宽分配方法进行仿真比较。结果表明模 糊带宽管理方法相对于固定带宽分配方法而言在提高系统控制性能的同时也节省了网络带宽。
