objective to discuss perioperative complication and management of patient with high risk copd following esophagectomy.methods 45 patients with high risk copd underwent esophagectomy with epidural block combined with general anesthesia.perioperative treatment included smoking cessation,chest physiotherapy,prevention and control of infection of air way and appropriate bronchodilators of air way,breathing exercises,nutrition support and oxygen therapy.painkiller was instilled after surgery,early exercises,ensuring unobstruction of the air way,mechanical ventilation was applied when needed.results 3 had hypoxaemia in operation.after surgery,all patients had spo2 somewhat declined.6 had lung infection.6 were removed of bronchial secretion by bronchoscope.2 were supported by ventilator by using intubation.2 underwent tracheotomy.1 had disturbances of acid base balance and treated by using hydrochloric acid muriatic acid.all patients recovered rather smoothly and discharged from hospital.conclusion high risk copd is not the absolute contraindication of esophagectomy.active management before and after surgery ensures the safety and recovery of patients.

目的 探讨重度慢性阻塞性肺疾病简称慢阻肺病人食管切除术围手术期常见并发症及其处理。方法 45例重度慢阻肺的病人在全麻联合硬膜外阻滞下进行开胸食管切除手术，围手术期处理包括术前戒烟、胸部理疗、预防和控制呼吸道感染、解痉化痰、呼吸功能锻炼、营养支持和氧疗；术后硬膜外镇痛、早期锻炼、保持呼吸道通畅，部分病人予以呼吸支持。结果术中3例出现低氧血症。术后所有病人pao2均有不同程度的下降，6例出现肺部感染，6例行纤维支气管镜吸痰，2例通过气管插管给予呼吸机支持，2例行气管切开术，1例酸碱平衡紊乱使用盐酸精氨酸治疗。所有病人均痊愈出院。结论重度慢阻肺病人并非开胸食管切除手术的绝对禁忌证，积极的术前准备和严格的术后管理可减少和控制术后急性发作，有助于确保此类病人的围手术期安全和康复。

To prevent epidemical disease prevalence caused by microorganisms in indoor air, a study was carried out to investigate the effect of ventilation, peracetic acid and ozonization on microorganisms reduction in the indoor air within a campus. The experimental results indicated that ventilation was an effective measure in reducing indoor air microorganisms with economy and simple operation.

为了防止室内空气微生物导致的传染病发生，对某校园室内的空气进行通风、过氧乙酸和臭氧灭菌降低微生物的实验研究结果表明，通风可以有效地降低室内微生物的浓度，是最为经济和易行的措施；过氧乙酸灭菌效果好，持续时间较长，可在不易实施通风情况下采用过氧乙酸灭菌；臭氧具有迅速杀菌的效果，使用时要与人保持一定距离，最好超出 1m。

By constructing the piecewise linear function from samples, it is able to approximate the measured metric more precisely. Compared with current popular sampling algorithms, FASM algorithm can provide more precise estimation of metric under the same samples. In the condition of retaining the same approximation errors, our adaptive sampling methodology only requires fewer samples, which will save sampling costs considerably during sampling process.

与当前常用的抽样算法相比，在采集相同的样本数量情况下，本文的拟合模型对指标进行的估计更准确、稳定；而在保持相同的拟合误差时，自适应抽样算法则可显著减少所需采集的样本数量，节约数据采集过程的代价。

Compared with U.S. and EU, China airline industry is still in the transition process from central planning to a market economy, has prominent characteristics of administration monopoly, and face kinds of constraint factors for full deregulation. So the government should push the regulation reform orderly on the base of prudentially balancing efficiency, sustainable development and public interest.

与美欧相比，我国民航业仍然处在向市场经济过渡的转轨阶段，仍然保持着相当浓厚的计划经济色彩和行政垄断特征，仍然存在着限制全面放松规制的各种因素，为此应以2002年启动的全面体制改革为契机，在权衡效率、可持续发展、有效竞争和公共利益等目标的基础上有序推进我国民航业的规制改革。

When the power system load in a small disturbance, the system itself to maintain the stability of the power transmission capacity, the use of automatic excitation regulator device may reduce the reactance of the generator, and then further to maintain the transformer high-voltage bus voltage constant, so compensation not only its own reactor, but also compensation for the step-up transformer reactance, thus greatly improving the power limits of generators, which greatly increased the static stability of power system.

当电力系统的负载发生微小的扰动时，系统本身保持稳定送电的能力，使用自动励磁调节装置，则可减小发电机的电抗，再进一步维持变压器高压母线的电压恒定，这样不仅完全补偿了自身的电抗，而且还补偿了升压变压器的电抗，这样就大大提高了发电机的极限功率，即大大地提高了电力系统的静态稳定。
