热能与动力工程专业毕业论文

你小子是写作文呀。

给你个提纲，自己去补充内容。什么都靠别人帮助，最后倒霉的是你自己。

1，能源动力是人类体力的扩展；

2，能源和动力机械开创了人类的工业革命，极大地提高了生产力；

3，英国人发明了蒸汽机，取得了工业革命的领导地位；

4，美国人广泛应用蒸汽机铁路，和内燃机公路，取得了二战后的领导地位；

5，化石能源的寿命是有限的，人类需要可再生的能源；,

6，传统的化石能源，煤和石油也给环境带来了污染，威胁到人类的生存；

7，太阳是一切能源的根本来源，光伏发电，风力发电，生物质能源等新能源都是来自太阳；

8，人类需要清洁的新能源来保障可持续发展，同时也保护人类赖以生存的自然环境；

9，科技进步和技术创新是人类寻找新能源的途径。

包括你自己在内，不爱花力气不爱动脑子，等到没有能源时，将会蜕变为猿人。

Over the last 20 years, mainly due to the vibration caused by the fatal accidents occurred one after another, inflicting huge economic losses. Furthermore, the vibration is still new to large units shipped impossible grid, the normal operation for the main the crew during normal operations, continuous vibration problems affecting the normal production, Units often reduced load and operation of the sick, and even the unit was forced to stand, these incidents not uncommon. The system based on LabVIEW virtual instrument software platform for turbine vibration signal window read, and spectral analysis and correlation analysis. LabVIEW virtual instrument is a common core of computer hardware platform, defined by the user, with virtual front panel, the test function test software from a computer equipment system. The system completed the turbine vibration signal read, the signal rectangular window Hanning, Hamming window window choice, and then the signal amplitude spectrum, power spectrum and phase spectrum analysis and correlation analysis, and operating with graphics and display interface. The result of running the system proved that the system can accomplish the signal read, and three window function and the dynamic analysis of the various options and graphical display with the results.

《燃煤电厂锅炉烟气净化用除尘过滤材料的试验研究》，这是我的题目，只要是试验部分很难。但是苦恼的很，还是学长给的莫文网，很快就帮忙搞定了

参考下吧：针对工程需求,本课题重点改进了针刺滤料结构、材料组成和后

整理措施,即采用具有表面超细纤维层、逐层逐渐采用更粗纤维层的梯度结构过滤层主要采用PTFE与PPS复合纤维,采用PTFE与适量玻璃纤维做底层,。
