机械专业面试英语
英语面试是复试中的一根钉，如何拔出这根钉是考生最关心的话题，对于考研英语面试中自我介绍也是大家最担心和关注的问题，考生不难发现网上的自我介绍铺天盖地，但是同学们不能直接copy下来背，上次我们给大家整理了自我介绍的模板，大家还需要结合自身的情况整合一下，那么我们下面给大家分享下在英语面试中的常问问题以及对策：1.Why do you choose our school?The reason why I choose our school is that it is a prosperous and comprehensive university, and meanwhile the professors are the Chinese academy of science, the founder of…Then, the atmosphere of the study does attract me a lot and I also want to improve myself by competing with the other students.2. Please introduce your hometown.I am so proud of my hometown, which is a beautiful city and provide us comfortable life. Meanwhile it is known for…I am looking forward to waiting my dear teachers to visit my hometown, which will be transformed into a beautiful memory.3. How do you handle your failure?(你怎样对待自己的失败?)None of us was born "perfect". I believe I can be given a second chance to correct my mistake.4. What are your goals? (你的长期短期目标)My immediate goal is to improve my professional knowledge by study from teachers.I hope to eventually grow into a position of responsibility.”5. Why do you choose this profession? (你为什么选择你报考的专业?)Maybe it depends on my personality, an innovative achiever. I feel that in a growth industry like… I want to take a step forwards as long as I start my plan.同时我们也给大家几句万能句，这些万能句也是考验真题作文中的万能句，大家如果之前没有背过真题作文，现在开始要准备这些句子，以备英语面试口语中用：It is important to take concrete measures to put this phenomenon on hold (push forward this phenomenon).First and foremost, relevant authority is expected to make some rules or regulations in regard to +主题, and improve people’s awareness of doing sth at the same time.For another thing, as citizens, we should step up efforts to support/fight against+ 主题词.Owing to +主题, not only can we accumulate wealth, but also establish our career, fit into society and even attain social status.由于面试的时间紧，我们的准备更要有计划，更有针对性的复习，那么这个时候大家就可以把以前复习过的东西按照复试中的要求整理，首先专业课笔试，要注意基础知识及总结性的东西，回答时加上自己的观点。
机械类复试面试问题汇总(200多道题)
1．什么是刀具前角,在哪个平面内测量?前刀面与基面之间的夹角，在正交平面内测量2.轴承分哪几种,简单介绍一下?（合工大）按其所能承受的载荷方向可分为：①径向轴承，又称向心轴承，承受径向载荷。
②止推轴承，又称推力轴承，承受轴向载荷。
③径向止推轴承，又称向心推力轴承，同时承受径向载荷和轴向载荷。
按轴承工作的摩擦性质不同可分为滑动摩擦轴承（简称滑动轴承）和滚动摩擦轴承（简称滚动轴承）两大类。
3.渐开线齿廓有哪些特征?(1)发生线沿基圆滚过的长度等于基圆上被滚过的弧长;(2)渐开线的形状取决于基圆的大小;（3）基圆以内无渐开线；（4）渐开线上各点压力角不相等。
离基圆越远，压力角越大。
（5）只要渐开线齿廓制成以后，基圆半径不变，传动比不变，这是渐开线齿廓的可分性。
4.齿轮变位有哪几种,介绍一下它们的特征大齿轮用负变位，小齿轮用正变位。
径向变位齿轮与标准齿轮相比，其模数、齿数、分度圆和基面均无变化，但是正变位时分度圆齿厚增大，齿根圆和齿顶圆也相应增大，负变位时分度圆齿厚减小，齿根圆和齿顶圆也相应减小。
5.什么是六点定位原理?采用六个按照一定规则布置的约束点来限制工件的六个自由度即完全定位称之为六点定位原理。
6.什么是过定位、欠定位,是否都允许,为什么,各举个例子欠定位按照加工要求应该限制的自由度没有被限制的定位称为欠定位。
欠定位是不允许的。
因为欠定位保证不了加工要求；过定位工件的一个或几个自由度被不同的定位元件重复限制的定位称为过定位。
当过定位导致工件或定位元件变形，影响加工精度时，应该严禁采用。
但当过定位并不影响加工精度，反而对提高加工精度有利时，也可以采用。
7.火车开来和离去的声音不同,为什么?这叫多普勒效应。
简单的说,声音就是空气的振动产生不同波段的波，当火车运动时，其发出的振动声音的波长相对地面的人就会发生改变。
波段不同，声音听起来就要变化。
当火车向人驶来时，声音的波长相对于人变短，因此听起来比较尖；当火车远去时，声音的波长相对于人变长，因此听起来比较钝。
