Three Qualities in My Future Spouse Introduction
I. Similar interests
II. Be trustworthy
III. Get along with family
Conclusion
Three Qualities in My Future Spouse
Finding a right spouse which means finding a person who I can see myself growing old with and loving in my later life. Once I have determined that special person, all of my hard work will be worth it and I can get ready for a lifetime of happiness. My right spouse should demand some qualities that I would like to have in the future.
She should have similar interests with me. The common interest can be a launching point for an everlasting relationship. If I am a novelist and my loved spouse refuses to read, we may run out of things to talk about. Common interests can make a relationship thrive. For example, we should have the same family values. The woman I am going to marry should have similar interests.
She should be trustworthy for me. In fact, If she does not trust me, she is probably making me as bitter as she has making herself. I can not work on confidence issues within herself without trust between us. Happy family and successful career demand she’s trust in me. So she’s good trust in me is the most important reason to go together.
She should get along with my family. If she does not even try to connect with my family shows she should not be critical of the people who I love and have been loyal to me throughout my life. There might be cases where my parents do not like my future wife. Marriage is a joining of two lives that existed prior to meeting the other person. Getting along with my family is a guarantee of our happy marriage.
Consider the three qualities I want in a spouse. These qualities may be so
important to me that I would have a hard time even considering a person who I should get married because that is what I want and what my family wants. I regard these three qualities that I am most looking for in my future spouse as the most valuable condition definitely.

专业点题北航机械原理
一、齿轮传动的基本概念 渐开线齿轮的啮合特点：(1)渐开线齿廓能够保证定传动比;(2)渐开线齿廓之间的正压力方向不变;(3)渐开线齿廓传动具有可分性。 齿轮机构的特点是：传动平稳、适用范围广、效率高、结构紧凑、工作可靠、寿命长。但制造和安装精度高、制造费用大，且不适合于距离较远的两轴之间的传动。齿轮传动可以用来传递任意轴间的运动和动力。 齿轮传动按照一对齿轮传递的相对运动分为平面齿轮传动和空间齿轮传动，平面齿轮传动又分为直齿圆柱齿轮传动、斜齿圆柱齿轮传动和人字齿轮传动;按照工作条件可以分为开式传动、半开式传动和闭式传动。 齿轮传动的基本要求是：传动准确、平稳;承载能力强。 二、齿轮传动的设计与计算 齿廓曲线与齿廓啮合基本定律：在啮合传动的任一瞬时，两轮齿廓曲线在相应接触点的功法线必须通过按给定传动比确定的该瞬时的节点。 渐开线齿轮啮合的正确条件：啮合轮齿的工作侧齿廓的啮合点必须总是在啮合线上，即两齿轮的模数和压力角应该分别相等。 齿轮传动的无侧隙啮合及标准齿轮的安装：一个齿轮节圆上的齿厚等于另一个齿轮节圆上的齿槽宽是无侧隙啮合的条件;外啮合齿轮的标准中心距为，内啮合是标准中心距为。
齿轮及其变位的相关计算：相关参数为齿数、模数、分度圆压力角、齿顶高系数和顶隙系数及标准直齿轮的几何尺寸计算，包括分度圆直径、齿顶高、齿根高、齿全高、齿顶圆直径、齿根圆直径、基圆直径、齿距、齿厚、齿槽宽、中心距、顶隙以及变位齿轮的变位系数等。 渐开线齿轮的根切现象：用展成法加工齿轮式，若刀具的齿顶线或齿顶圆与啮合线的焦点超过被切齿轮的极限点，则刀具的齿顶会将被切齿轮的齿根的渐开线齿廓切去了一部 分。避免根切的最小齿数，用标准齿条刀具切制标准齿轮时，因为 ，最少齿数为17。 三、机构的组成 构件指独立的运动单元，两个构件直接接触组成仍能产生某些相对运动的连接叫运动副。运动副按照相对运动的范围可以分为平面运动副和空间运动副;按运动副元素分为：低副-面接触、应力低;高副-点接触或线接触，应力高。其中运动副元素是只形成运动副的组建之间直接接触的部分。 四、机构自由度的计算 机构相对于机架所具有的独立运动的数目，叫机构的自由度。设一个平面机构由N个构件组成，其中必定有一个构件为机架，其活动构件数为n=N-1.设机构共有个低副、 个高副，因为在平面机构中每个低副和高副分别限制两个自由度和一个自由度，故平面机构的自由度为。在计算平面机构的自由度时，应该注意三种特殊情况：(1)复合铰链：三个或更多的构件在同一处联接成同轴线的两个或更多个转动副，就构成了复合铰链，计算自由度时应该按照两个或更多个运动副计算。(2)局部自由度：在有些机构中，为了其他一些非运动的原因，设置了附加机构，这种附加机构的运动是完全独立的，对整个

北京大学考博英语历年试题分析
北京大学考博英语历年试题综合分析 导言：考博英语真题的重要性 全国各大院校在制定本校英语专业考试大纲时，对英语的考核基本上不指定参考书，考生在备考时往往感到漫无目的，无所适从，所以对各大院校的考博英语历年真 题分析则显得尤为重要。华慧考博英语教研中心在历时8年的教学研究的过程中，总 结国内50多所重点院校的考博英语试题的出题特点与规律，认为考生精研各院校的历年试题对考出良好的成绩有非常大的帮助。 考博英语试题的独特性 众所周知，英语类的考试，如高考、大学英语四六级、专业四八级考试、研究生 入学考试等均由统一的命题组人员统一命制试题，命题组阵容强大，且耗费的人力、物力也不在少数，其题目基本是原创题目。而考博英语却并非这样，因此，考博英 语有其自身的独特性，考博英语的独特性主要表现在其命题方式与题目来源两方面。 首先，从命题方式来看，博士考试中，要求考生达到英语的最低分数线，这一要 求就注定了各大考博院校的英语试题的命题方式，各大考博院校不会花费大量的人力、物力及时间原创一套考博英语试题。并且各大院校为了保证其试题的准确性，一般会 选择已经考过的各类相关难度的试题，这样就可以避免出现大量的因个人学术水平方 面而引起的错误和争议。 其次，从题目来源看，各大院校的考博英语试题基本来自专四、专八、六级、杂 志文章或其它考博院校的原题，极少出现原创题目。因其题目来源的独特性，我们研 究各大院校的考博英语试题就显得非常有必要且益处极大。如果考生在考前了解了这 一情况，且充分重视这个规律，那么获得考博英语高分不是什么难事。所以考生考前 精研考博英语真题是非常有必要的。
