简介:摘要:“化学平衡”在高中化学阶段有着举足轻重的作用,在此模块中有一个重要的具有重要且具有功能性的物理量:“化学平衡常数”。有很多实践研究者提出在一线教学中引入K可以帮助学生理解化学平衡,从而提升学生对化学反应限度的认识。在本文中,笔者实行了一定的教学策略得出了基于K为本质的复习教学能够转变学生迷思概念的结论。
简介:摘要:采暖供热管网的平衡是确保供热系统正常运行的关键问题。本研究旨在探讨采暖供热管网平衡综合水力平衡调节方法,以提高供热系统的能效和稳定性。通过对管网水力特性和系统运行状态的分析,结合实际工程案例,提出了一种综合水力平衡调节方法,并对其进行了验证和评估。研究结果表明,该方法可以有效解决采暖供热管网中存在的水力不平衡问题,提高系统的水力性能和供热效果。本研究对于优化采暖供热系统的设计和运行具有一定的指导意义。
简介: I therefore encourage you to take both English and your mother tongue language very seriously. They are both good for your future. Those who are able to should also try and pick up at least a casual knowledge of another Singapore language,will give all of you a good future. It will allow you to reach out to a world of knowledge and technology,they start at Primary Three. And there is huge demand for English language training among those who have already left school - either because they did not have a chance to learn the language earlier or because they are trying to achieve a higher command of the language.
