麻烦帮我翻译一下，谢谢！急！

Spectrum analysis of field data of combined cycle power plant：
The phenomenon of drum level sloshing is found in operational field of combined cycle power plant in General Electricity Company in USA. In order to reveal the phenomenon at least four drum level sensors are installed symmetrically on the drum, and from the analysis of the field data of drum level, the phenomenon of drum level sloshing and wave action can be discovered, especially when the HRSG runs smoothly.
Fig.15 to Fig.18 show the field data of drum level from A, B, C, D drum level sensors given by some combined cycle power plants, and also the corresponding spectrum analysis done by us. Here A, B sensors are installed at the same end of drum, and symmetrically C, D sensors are installed at opposite end. It is obvious from the spectrum analysis that different drum level from opposite drum side is reverse. Most power of drum level is focus on the 0-0.05HZ, the left power of drum level is focus on around 0.05-0.1HZ.
Combined the simulation result with the field data and its spectrum analysis, it can be found that the signal with frequency smaller than 0.05HZ are the signal of drum level trendy and ‘false water level’, and the signal with frequency bigger than 0.05HZ are the signal of drum level sloshing and wave action. The critical value should be further studied, and it may be changed according to operational condition of HRSG. Next work of this research is to further confirm the critical frequency, and design the filter to delete the signal of drum level sloshing and wave action. So the ratio of signal to noise of drum level will be improved, which will be better for the precise controlling of drum level in the combined cycle.

频谱分析实际资料的联合循环电厂:
鼓水平晃动的现象被发现在业务领域的联合循环电厂一般电力公司在美国。摘要为揭示现象至少四鼓水平传感器安装对称鼓声,从实测资料分析鼓之间的水平,这一现象的鼓水平晃动和波浪作用会被发现,尤其是当余热锅炉运行平稳。
对Fig.18不致显示实际资料的鼓级A、B、C、D鼓水平传感器受到联合循环发电厂,并相应的谱分析由我们。这里A、B传感器安装在同样的结局的大鼓,对称C、D传感器安装在另一边。很明显,从频谱分析的方法,不同的鼓水平从对面鼓边反转。大多数的力量集中在鼓水平的力量0-0.05HZ鼓,左边就是专注于周围0.05-0.1HZ水平。
结合数值模拟结果与实测资料和它的频谱分析,可以发现,随着频率小于信号的信号0.05HZ水平是时尚又“虚假鼓水位'、信号频率的信号比0.05HZ鼓水平晃动和波浪作用。的关键值进一步的研究,可以根据工况变化的余热锅炉。下一步工作本研究以进一步确定临界频率,并设计出该系统的信号滤波来删除鼓水平晃动和波浪作用。所以信噪比鼓水平将会得到改善,这将是更好的为得到精确控制水平的鼓之间的联合循环。
能选我的答案吗？谢谢O(∩_∩)O谢谢

这样的大段翻译只给5分是不是少了点...而且，很多这样的翻译都是要钱的...
