The Application of Cohesion and Coherence Theory in Advanced College English Teaching

In 1976,Halliday and Hassan put forward the concept of cohesion and coherence theory for the first time in their book English Cohesion and discussed five types of cohesion:reference,substitution,omission,conjunction and lexical cohesion.Some scholars enriched and expanded cohesion and coherence from the perspective of cohesion conditions,phonology,structural relations at the level of meaning and discourse.Predecessors pay much attention to the theoretical discussion,while from the perspective of the theoretical application,the cohesion and coherence theory is used for analyzing the advanced college English textbook to provide the guidance for teachers and students in teaching and learning-teachers can judge and adopt appropriate teaching methods according to the cohesion and coherence theory;Students can understand cohesion and coherence in the text as well as the influencing factors,and adequately use the cohesion and coherence mechanism in listening,speaking,reading and writing.

The first prototype of cable-driven mechanisms is RoboCrane, which was developed by the National Institute of Standards and Technology （NIST）. Then many excellent properties were developed and they have a variety of applications such as aerospace, aircraft and automobile industries [1]. Example application for RoboCrane in the field of aircraft mainte- nance is equipped with a quick-change mechanism to remove the robot arm remotely.

Classical Theory of Advance of Perihelion of Mercury with Velocity Dependent Inertial and Gravitational Masses

It is shown that Mercury's motion of the perihelion around the Sun, which is believed to be explicable quantitatively only by general relativity, can be fully understood within the frame of the dynamics of special relativity. It is only necessary to take into consideration the relativistic dependence of the planet's inertial and gravitational masses on its velocity (relative to the Sun) in the conservation equations for energy, and linear and angular momenta in the gravitational field. The physical Problem is reduced to a singular, nonlinear differential equation, which is solved numerically for the planet Mercury. The advance of the perihelion of Mercury is shown to be = 42.087' for a period of 100 years, which is in agreement with the as- tronomical observations and the result (by analytical approximations) of general relativity.

基于波动应力信息的隧道地质三维超前探测技术

在隧道施工过程中,地质超前预报技术是必要手段和工序,也是制约隧道施工技术发展的关键技术难题。地震波法隧道超前地质预报施作是一个力学过程。本文将隧道围岩假设为固、气(孔隙)双相介质,在Biot波动理论的基础上,通过分析人工地震波引起的围岩应力应变关系,结合反射面处的地震波入射、折射、透射连续方程及波阻抗与反射系数关系,得到了围岩广义应力梯度与地震波瞬时振幅与瞬时频率之间的关系表达式,并建立了围岩应力信息与地质信息的联系。在此基础上,将隧道围岩广义应力梯度作为评价地质灾害的重要指标,形成了基于围岩应力信息的地震波超前地质预报方法,解决了现有预报多解性问题。经过现场试验验证,围岩应力信息能够很好地表达地质岩性变化,结合波速和走时,可以准确判定地质灾害规模、类型及位置。

基于“焦络理论”探讨晚期肺癌的治疗思路

晚期肺癌的证型多为瘀阻肺络证、痰热壅肺证、肺脾气虚证、气阴两虚证,其中气阴两虚证患者多见于Ⅲb期和Ⅳ期;而焦络理论认为“三焦不通、肾水不足、玄络闭塞”是百病之源。刘华教授认为三焦-络脉-玄府这一通路与肺癌发生、癌毒传舍等关系密切,故以“焦络理论”为指导,分析晚期肺癌的病因病机,认为邪毒犯肺,其性偏“湿”贯穿肺癌发病及转移的始末,肺络痹阻,肾虚痰凝是病机关键,故提出补肾化痰、通络解毒这一治则,主张攻补兼施,肺肾同治。文章对1例晚期肺癌患者的诊治进行分析,予以化痰抗癌与益气养阴相结合,共同作用于肺肾,使邪祛正安,共同作用于肺肾二脏。并在二诊、三诊中进行随症加减全方以益气养阴、止咳化痰为主,又肺肾同源,兼顾补肾,攻补兼施,达到治病目的。文章为后续研究提供参考,以期共同探讨治疗晚期肺癌的治疗前景。

基于传染病和网络流模型分析APT攻击对列车控制系统的影响

高级可持续威胁(APT)是目前工业控制系统面临的主要威胁之一。APT攻击利用计算机设备漏洞入侵列车控制网络,感染并且扩散到网络中的其他设备,影响系统正常运行,因此评价APT攻击对列车控制系统的影响非常必要。提出一种基于传染病模型和网络流理论结合的APT攻击影响分析方法。首先,分析在APT攻击的不同阶段设备节点状态之间的转化规则,结合传染病理论建立APT攻击传播模型,研究攻击过程中的节点状态变化趋势;其次,把设备节点的状态变化融入网络流模型中,研究APT攻击过程中设备节点状态变化对列车控制网络中列车移动授权信息流的影响;最后,结合列车控制系统的信息物理耦合关系,分析APT攻击对列控系统整体性能的影响。仿真实验展现了APT攻击过程中节点状态变化的趋势,验证该方法在分析APT病毒软件在列车控制网络中的传播过程对列车控制系统整体性能影响的有效性,为管理者制定防御方案提供依据,提升列车控制系统信息安全水平。

脑卒中患者接受预立医疗照护计划影响因素的质性研究

目的了解脑卒中患者接受预立医疗照护计划(ACP)的影响因素,为在脑卒中患者中开展ACP提供参考。方法2022年12月至2023年6月,采用目的抽样方法,选取广西某三级甲等医院康复科收治的11例脑卒中患者作为研究对象。采用现象学研究方法,对其进行面对面半结构式深度访谈,运用Co-laizzi七步分析法对访谈资料进行分析。结果针对脑卒中患者接受ACP的影响因素共提炼出3个主题:行为态度消极(对ACP了解少、对ACP需求低);主观规范压力大(社会支持度欠佳、对ACP存在抵触心理);知觉行为控制困难多(对医务人员的信任度不一、客观因素不成熟)。结论脑卒中患者接受ACP的影响因素较多,医护人员应纠正患者对ACP的认知偏差,帮助其争取社会及家庭支持,同时加强ACP的客观支持,从而促进患者行为意向的转变,以提高其对ACP的接受水平。
