正交胶合木(CLT)是一种适合于建筑工业化的人工绿色材料,具有可预制、可再生、自重轻但强度和刚度较高等特点,有较好的环境效应。如果能够在正交胶合木基础上加上预应力,则该组合结构受力性能将会得到进一步提升。主要对不同初始张拉力... 正交胶合木(CLT)是一种适合于建筑工业化的人工绿色材料,具有可预制、可再生、自重轻但强度和刚度较高等特点,有较好的环境效应。如果能够在正交胶合木基础上加上预应力,则该组合结构受力性能将会得到进一步提升。主要对不同初始张拉力下预应力-正交胶合木组合结构进行试验研究:考虑预应力钢绞线的2种不同初始张拉力,设计了2个CLT剪力墙构件进行拟静力往复加载试验,得到了2个构件的骨架曲线、刚度退化曲线、等效粘滞阻尼系数、变形模式等内容;同时,通过将试验结果与国内相关研究成果进行对比分析,发现施加预应力对CLT结构整体刚度、耗能能力等有较大提升;相比于预应力-木组合结构组装于钢底梁上,预应力-木组合结构组装在混凝土底梁上在一定程度上减少了钢节点的使用,缩小了两者之间的刚度差,使得混凝土底梁情况下构件屈服荷载、屈服位移以及最大承载力方面有一定的提升。 展开更多

This article discusses Task-based Language Teaching(TBLT)implemented in the Chinese classroom.TBLT involves a three-phase pedagogical sequence,including pre-task,on-task,and post-task.Different task-based learning activities are designed to promote learners’language acquisition through the performance of tasks.Learners are engaged in interactive and collaborative communication to accomplish meaningful and relevant real life tasks.This article explores the application of one TBLT unit in Chinese for learners’language development in terms of both fluency and accuracy. 展开更多

Objective Access to improved sanitation is a fundamental human right and an important aspect of Public Health.However,an estimated thousands of people in Ghana especially,the West Mamprusi Municipal Assembly(WMMA)still have no access to adequate toilet facilities.This has brought untold health repercussions to the inhabitants,the community,and the environment at large.To address this menace,the community-led total sanitation(CLTS)was implemented.This study aimed to assess communities’perspectives on the implementation of CLTS and to understand the factors influencing its success and failures.Methods A mixed-method approach involving sequential qualitative and quantitative methods was employed in this study.Participants for the quantitative study were randomly selected and surveyed using questionnaires.The qualitative study employed focus group discussion involving purposively sampled participants including assembly members,opinion leaders,and assembly staff.Results The CLTS program in WMMA realized an apparent use of construction and proper use of household latrines leading to a reduction of open defecation free(ODF)and two communities achieving sanitized status in the history of the study area,enabling the training of latrine artisans and natural leaders to facilitate the CLTS expansion and sustainability,improved sanitation and hygiene,strengthened the enforcement of community rules and regulations and many others.Conclusion The CLTS program has received more widespread acceptance in the study area than the previous government policy of constructing public toilets,which was greeted with massive failures due to poor implementation.To ensure that gains achieved through CLTS implementation are sustained longer,it is recommended that chiefs and opinion leaders should be involved in the CLTS programs to ensure checks and enforcement.The entrenchment of bylaws and more education to address enduring myths and misconceptions will sustain the program.Subsidies in the form of sanitation loans for latrine construction materials by the government and supporting non-governmental organizations(NGOs)will be paramount in sustaining ODF. 展开更多

With the progress and development of society and the continuous advancement of curriculum standard reform,society has higher requirements for students’English skills.The junior high school stage is the best time to cultivate students’communication skills,however,junior high school English classes are currently still based on traditional teaching as the main teaching method,which only focuses on cultivating students’reading and writing skills,thus neglecting the training of listening and speaking skills.Despite its evident benefits,the implementation of the task-based language teaching(TBLT)method in junior high school English communication classes is not without challenges.The current state of these classes reveals a significant gap in the integration of communicative tasks into the teaching process.This gap stems from a variety of factors,including the lack of appropriate resources,insufficient teacher training,and the deeply ingrained reliance on traditional teaching methods.This study will briefly explain the definition and characteristics of the task-based language teaching method,analyze the current situation of junior high school English communication classes,the difficulties of using TBLT in junior high school English classrooms,and the application methods of task-based teaching methods.The teaching method makes up for the shortcomings of English communication classes in junior high schools and improves the quality of teaching. 展开更多

Task-based language teaching approach(TBLTA), which lays stress on "learning by doing", gained increasing popularity in English teaching in recent years. The design of phonetic teaching calls for more emphasis from English educators since it is one of the basic rounds of English teaching. This paper made a trial on the utilization of TBLTA in the English phonetic teaching context and designed a TBLTA model for English phonetic teaching based on discussions about model and merits of TBLTA. 展开更多
