摘要：肺癌术后肺部并发症(postoperative pulmonary complications,PPCs)风险预测模型能帮助医护人员识别患者PPCs概率,为临床医护人员快速决策提供依据。本文评估和总结肺癌PPCs风险预测模型的研究现状,从模型类型、构建方法、模型性能、临床应用等方面分析其优势、不足与挑战。发现目前肺癌PPCs风险预测模型对PPCs发生有一定的预测效能,但其在研究设计、临床应用及透明化报告等方面存在一定的不足。建议今后开展大样本、前瞻性和多中心研究,构建多组学预测模型,实现精准预测,促进临床转化应用与推广。

摘要：海洋石油平台上部组块和钻机模块分别单独使用空气压缩机制造仪表气已有多年经验。文章从降本增效理念出发,将上部组块和钻机模块的仪表气系统进行一体化工艺设计,详细阐述了仪表气一体化工艺设计原则和注意事项;通过引入高压氮气工艺流程,优化密封隔离性仪表气罐尺寸,解决了因密封隔离性仪表气罐尺寸较大而影响平台总体布置的难题。

摘要：This paper aims to make study on Tess’death from two major areas,which includes social factors and human *** the perspective of social factors,the moral concept in Victorian era tends to be *** double standard towards chastity entrenched in people’s *** are oppressed by such moral concepts and controlled by *** is the one who is prosecuted by such ***,the rise of capitalism changed the old economic form,which made devastated blow to the peasant class,Tess belongs to the peasant class,her fate is also influenced by such devastation;apart from conservative moral concept,unfair law and hypocritical religion are also responsible for Tess’*** Victorian era,law and religion serve for the bourgeoisie and protect their interest instead of the peasant class like Tess,which indirectly caused Tess to kill Alec and become a *** the view of human factors,Tess’parents,Alec and Angel also play an important role in Tess’*** for her parents,who are vain and selfish,devoted to marry their daughter a rich husband and do not care about her own happiness;besides,Alec obsessed with Tess’beauty and seduced her,which directly made her be despised by people and feel immoral about herself;and Angel’s love also made Tess lives a more miserable life,since his initially strong love aroused Tess’hope but the final abandon threw her down to the *** all the three social factors and two human factors,Tess’tragedy is inevitable.

摘要：Based on Hyland’s(2005)framework of stance,this study explored the distribution of authorial stance used by undergraduates in their BA *** two self-built corpora,the result of the study shows that the use of stance markers in the corpora displays the following sequence:hedges>boosters>attitude markers>*** analysis on each stance marker reveals that undergraduates,as novice academic writers,have some problems with appropriately using stance markers in their academic *** results provide some implications for both student writers and teachers of academic writing.

摘要：根据现有主减反共振隔振和主动控制理论,设计新型直升机主减隔振原理样机模型。随着直升机工作频率的改变,隔振系统识别频率的变化,自动调节隔振器质量块位置,使系统始终有隔振效果。以直升机原理样机为对象,加入基于神经网络的控制方法,对实验对象进行动力学特性标定,获得质量块位置与工作频率之间的关系。研究频率跟踪算法,将神经网络和频率跟踪算法两者结合,编制出可以采集信号,识别频率的LabVIEW程序。实验结果证明,新型主减隔振系统隔振效果和控制效果符合预期,可以为直升机主减的振动主动控制系统设计提供一定的指导。
