工程热力学有多重要怎样才能学好（热力学工程公式学）

工程热力学对能源动力、建能、航空航天专业地学生超级重要，是学习其它专业课的基础，也是将来科研开发的基础，也就是说是将来的饭碗。

工程热力学课程是世界范围内超级的难学习、难教课程。

美国UCI的一个公开课，前面讲这个课程太难了，后面讲了卡诺循环的证明，而证明方法还是错的，为什么是错误将在讲课中说明。

为什么这么难？

课程内容比较多、研究对象是气体、公式多、概念多、比较抽象。

很多学生开学初一般不好好学习，以为概念不重要，不重视，到了5-9周一些同学几乎听不懂老师在讲什么。原因是学生没有思考没有记住前面所学的概念。

教材不适合学生自学。我教了33年80余次本科生的66-77学时的工程热力学，只有个别学生可以看下去，而且是在课间休息时间不断提问的情况下进行的。

教师对课程的理解对教学也有很大影响，最近在网上看了几所名校的国家级精品工程热力学课程课堂录制视频，各有特色，有的有受益。教到第二定律的时候，从学生上课表情来看，有的大学学生是呆若木鸡（可能听不懂），有的大学学生是不耐烦（可能闲多了）。而广东海洋大学的学生这时候多数还听地津津有味，只有后面两排学生心不在焉。

还有更重要的原因是大、二三学生没有见过相关的设备没有见过，对设备和课程名词比较抽象。

你知道下面设备的部件名称吗？热力学学习中会用到。

发动机的压气机、涡轮

汽轮机

喷管

Engineering thermodynamics is of great importance to students majoring in energy, power, energy construction and aerospace. It is the basis of learning other specialized courses, and also the basis of future scientific research and development, that is, the future job.

The course of engineering thermodynamics is one of the most difficult to learn and teach courses in the world.

An open class of UCI in the United States, the first lecture is "this course is too difficult", the second lecture is about the proof of carnot cycle, and the method of proof is still wrong, why it is wrong will be explained in the lecture.

Why is it so hard?

The course content is more, the research object is gas, the formula is more, the concept is more, is more abstract.

Many students do not study well at the beginning of the semester, thinking that the concept is not important, do not pay attention to. up to 5-9 week some students can hardly understand what the teacher is talking about.The reason is that the students did not think and did not remember the previous concepts.

Textbooks are not suitable for students to teach themselves.I have taught engineering thermodynamics 66-77 credit hours to undergraduates for over 33 years and 80 times. Only a few students can read it, and it is done in the context of continuous questioning during breaks.

Teachers understanding of the course also has a great impact on teaching. Recently, I watched the video recorded in the class of state-level high-quality engineering thermodynamics in several famous universities online, which has its own characteristics and benefits.When teaching the second law, from the students in class expression, some college students are stupefied (may not understand), some college students are impatient (may be more idle).And guangdong ocean university (second class university) students at this time most still listen with interest, only the back two rows of students absent-minded.

There is also a more important reason is that the students have not seen the relevant equipment, not seen the equipment and curriculum terms are relatively abstract.

Do you know the part name of the following equipment?Youll see that in thermodynamics.
