英语重复方式的语篇粘合作用

在英语语篇中,重复方式起着非常重要的作用。这种作用体现在两个层次上,一是语篇的Textur层次,一是语篇的Textual层次。本文重点叙述重复的后一种功能,即从篇章语言学的角度揭示重复的超语句层次的组篇或成文功能,即语篇的粘合功能。     

功勋队绽放“六种文化理念”奇葩

大庆油田第四采油厂第二油矿五区三采油队大力加强企业文化建设,积极倡导“六种文化理念”,取得了较好的效果。 倡导“追求卓越,崇尚一流”的核心理念。在劳动组织优化改革试点的初期,针对“人员紧张,员工工作强度大,部分员工安于现状,甚至产生畏难情绪”这一实际,适时提出了“追求卓越,崇尚一流”的核心理念,旨在鼓舞队伍士气,     

Tribology Performance and Adhesive Strength Evaluation of TiAlSiN Coating

Scratch test and friction test were performed to evaluate the internal and external interface behaviors of TiAlSiN coating, respectively. The critical compressive and shearing stress of coating failure during scratch test were calculated and the values are 30.84 MPa and 4.98 MPa respectively. The average friction coefficients of TiAlSiN coating against 2Cr12Ni4Mo3VNbN steel are 0.70 (sliding speed 50 m/min), 0.63 (sliding speed 100 m/min), and 0.81 (sliding speed 150 m/min). The elements diffusion was analyzed by EDS. Al and Si element of coating material diffuse to the steel disc, except Ti element. The oxidation decreases with the increase of sliding speed, but the adhesion increases with the increase of sliding speed. More Al element diffuses to the steel disc at the high sliding speed, but the diffusion of Si element keeps almost constant at different sliding speeds.     

新市民城乡粘合催化作用的发挥需澄清六对问题

为更好发挥新市民在城乡一体化进程中的粘合与催化促进作用,需要澄清六对理论问题。它们是:城乡一体化中的"同等"与"等同"、"同化"与"化同",新市民粘合催化作用中的"同情"与"情同"、"同共"与"共同"、"现在"与"潜在"、"自动"与"触动"问题。     

浅谈排球运动常见的损伤及其预防

<正>排球是一项对人体要求相当全面的运动,具有明显的耐力性特点,同时对力量、速度、柔韧和灵敏等素质也有很高的要求。因此,排球运动中经常伴有大强度的爆发性动作,有时也会导致运动性损伤,应多加注意预防。一、排球运动中经常损伤的部位排球运动作为一项技能性要求很高的竞技     

基于主题的微博情绪与传播力关系研究——以"中美贸易战"为例

【Purpose/significance】this paper crawls the microblog related to the "Sino-US trade war" event, aiming to clari⁃ fy the relationship between the emotional characteristics and communication power of microblogs on different themes in the event, which is helpful to control and guide the public opinion.【Method/process】Firstly, we extract the topic of microblog data, classify the data into different emotion and calculate the emotional intensity, then we study distribution of emotion types,and discuss the relationship between the emotional types and the emotional intensity and the communication power of each topic.【Results/conclusion】The results show that: ①The analysis of the proportion and intensity of emotions of dif⁃ ferent themes can effectively identify the themes and emotions with potential risks. ②The analysis of the relationship be⁃ tween high proportion and high intensity of emotion and communication power in different themes can provide reference for formulating emotion guidance strategies.     

酸激发磷石膏地聚合物胶凝材料基本物理性能研究

以原状磷石膏、水泥、偏高岭土等为主要原料,磷酸或乙酸为激发剂,制备了酸激发磷石膏胶凝材料并探究其基本物理力学性能,研究了酸激发剂的种类及掺量对胶凝材料抗压性能和抗折性能的影响。研究结果表明：磷石膏、偏高岭土、水泥的质量比为45∶15∶40,掺加量为1-5%的磷酸或乙酸,制备的胶凝材料具有较好的抗压抗折性能;掺加量为4%的磷酸制备的胶凝材料28天龄期的抗压强度达到了30.97MPa,抗折强度3.64 MPa;掺加量为4%的乙酸制备的胶凝材料28天龄期的抗压强度19.03MPa,抗折强度达到了4.08 MPa;在自然养护条件下,磷酸激发的磷石膏胶凝材料的激发效果优于乙酸。
