腹腔镜全子宫切除术中手术室护理配合路径的应用效果

目的评价腹腔镜全子宫切除术中手术室护理配合路径的应用效果。方法选取2020年12月至2022年12月苏州大学附属张家港医院收治的108例腹腔镜全子宫切除术患者作为研究对象,按照随机数字表法将其分为对照组(54例)与观察组(54例)。对照组实施手术室常规护理服务,观察组实施手术室护理配合路径。比较两组的术后并发症以及术后康复时间。结果观察组术后并发症总发生率低于对照组,差异有统计学意义(P<0.05)。观察组术后康复时间短于对照组,差异有统计学意义(P<0.05)。结论腹腔镜全子宫切除术患者实施手术室护理配合路径,可减少术后并发症,缩短术后康复时间。

旅游体验的时间余白

体验是旅游研究中的关键问题之一,作者的思考基于此但又超出了这一范畴,提出可在两个旅游体验项目之间设置时间余白,以巩固刚刚发生了的体验效果,为接下来的新体验做好心理准备,由此有助于生成一种仪式感。文章基于社会对余白文化的认识提出了一个新的研究视角,即把旅游与社会,乃至与物理学结合起来,认为在旅游体验中应有复原意识,而时间余白则有助于这一思考。旅游者在体会到每一次体验获得的同时,也意味着某些失去,应力图把失去的应有感知拾捡回来,而对时间的关注将有助于这种意识的生成,因而本研究也可谓是关于旅游时间的讨论。

宽带8PSK解调高速数传接收机设计

受卫星信道热噪声、多普勒、畸变影响,传统八进制相位键控(8PSK)接收机性能不佳,速率不高,较少应用于航天测控通信系统。针对这一问题,设计并实现了一种基于FPGA的航天测控系统宽带8PSK解调高速数传接收机,采用Gardner算法实现时钟恢复,利用基于最大似然估计的鉴相算法完成载波同步,并用分数间隔的并行恒模均衡算法提高接收性能。该技术已应用于某接收系统并实现了600Mb/s 8PSK信号解调,误码率在1×10-3～1×10-8之间时,解调损失与理论值不超过2dB。宽带8PSK解调高速数传接收机可为我国二代中继系统提供支持。

Hall曲线在渤海油田热采井中的应用

将Hall曲线理论引入到海上稠油热采井的监测和管理中,建立起了热采井累积注水量与累积注入压力×注入时间的Hall曲线关系。应用结果表明,渤海油田稠油热采井的注入Hall曲线符合线性关系,运用该方法可以认识注入井的地层参数、实时监测注入井的异常变化情况和评价正常生产井的热采效果。

Study on evaluation of cities' ability reducing earthquake disasters

Cities ability reducing earthquake disasters is a complex system involving numerous factors, moreover the re-search on evaluating cities ability reducing earthquake disasters relates to multi-subject, such as earthquake sci-ence, social science, economical science and so on. In this paper, firstly, the conception of cities ability reducing earthquake disasters is presented, and the ability could be evaluated with three basic elements the possible seis-mic casualty and economic loss during the future earthquakes that are likely to occur in the city and its surround-ings and time required for recovery after earthquake; based upon these three basic elements, a framework, which consists of six main components, for evaluating citys ability reducing earthquake disasters is proposed; then the statistical relations between the index system and the ratio of seismic casualty, the ratio of economic loss and re-covery time are gained utilizing the cities prediction results of earthquake disasters which were made during the ninth five-year plan; at last, the method defining the comprehensive index of cities ability reducing earthquake disasters is presented. Thus the relatively comprehensive theory frame is set up. The frame can evaluate cities ability reducing earthquake disasters absolutely and quantitatively and consequently instruct the decision-making on reducing cities earthquake disasters loss.

快速康复护理在卵巢囊肿蒂扭转围手术期的应用效果

目的探究快速康复护理在卵巢囊肿蒂扭转围手术期的应用效果。方法选取东营市河口区中医院2018年1月至2020年12月收治的86例卵巢囊肿蒂扭转手术患者为研究对象,以随机数字表法分为对照组与观察组,每组各43例,分别实施围手术期常规护理、围手术期快速康复护理。比较两组术后康复用时(肛门排气时间、首次进食时间、下床活动时间、住院时间)及并发症发生率(肺炎、切口感染、下肢深静脉血栓、尿路感染)。结果观察组的术后肛门排气时间、首次进食时间、下床活动时间及住院时间短于对照组(P<0.05);观察组的并发症总发生率为2.33%,低于对照组的13.95%(P<0.05)。结论对卵巢囊肿蒂扭转患者围手术期实施快速康复护理,可缩短其术后康复时间,降低并发症发生率,效果理想。
