Thermal expansion is a common phenomenon in both metals and alloys,which is important for metallic material applications in mode industry,especially in nuclear and aerospace industries.A lower thermal expansion coefficient may cause lower thermal stress and higher accuracy.A new Zr-based alloy is developed and presented.The XRD diffraction results demonstrate that only a close-packed hexagonal phase (α or αphase) exists in the microstructure.The thermal expansion and mechanical properties are studied.According to the experimental results,the new Zr-based alloy presents a low thermal expansion coeffcient and good mechanical properties.Also,its thermal expansion coefficient is stable through solution treatment.

说到一心二用，我想大家肯定不会陌生。看过《射雕英雄传》的同学都知道，里边的有趣角色“老顽童”——周伯通，最拿手的武功“左右互搏之术”就是典型的例子。一心二用不仅仅存在于小说中，在现实生活里，也很常见。譬如有些同学喜欢边听歌边写作业，或是边看电视边吃饭，这些也可称为“一心二用”。那么，一心二用这么个看上去很神奇的能力，究竟是好是坏呢？ “高大上”的一心二用？ 最近，又有这样一则新闻：美国堪萨斯城
数学史蕴含着丰富的内涵价值,对于学生情感价值观的养成,有着重要的意义。我国著名数学家华罗庚曾经说过:“数学史对于数学教育的促进价值不言而喻。”著名数学家庞加莱也指

【摘 要】众所周知，初中学生正处于青春叛逆期，心智并未成熟，很容易对学习产生抗拒心理。尤其是面对传统的教学方式时，其厌恶感十分明显。这不仅影响教学效率，对学生亦毫无益处。因此，必须调整传统的教学模式，并将“情”与“趣”融入教学内容中，才能形成愉悦的教学氛围，进而提高教学效率。基于此，本文将研究“情”与“趣”与初中化学间有何关联，再根据研究结果总结出合理的教学方式，希望本研究可推动趣味化学教学的发
