In view of most situations , this vibration doesn ’ t come from equipments themselves . as a result , we construct a platen of vibration isolation which is a kind of effective vibrating suppression 鉴于很多情况下,这种振动并非来源于设备自身,因而建立隔振平台是一种有效的振动抑制手段。
With the improvement of science and technology , three kinds of straw - based wallboard have been developed in china : platen - pressed straw - based wallboard , extruded straw - based wallboard , and mould - pressed straw - based wallboard 随著科学技术的进步，以农作物秸秆为原料的复合墙体材料制造技术已在中国得到发展。
Through macroscopic examination , wall - thickness measurement , and metallographic examination of tube specimen taken from the bursted platen superheater of boiler no . 1 , the causes leading to tube - burst have been analysed 摘要通过对1号炉屏式过热器爆管管样的宏观检验、壁厚测量和金相检验，对爆管原因进行了分析。
For the limitation of the former soviet union boiler unit heating calculation standard methods in 1973 in the boiler furnace ， panel and platen superheater ， this paper puts forward the new methods of the boiler heating calculation 分析了前苏联73年锅炉机组热力计算标准方法中炉膛、分隔屏过热器和屏式过热器计算方法的缺陷，初步提出锅炉热力计算新方法。
This text is based on a large air spring vibration isolation platen . we develop a new style of active vibration isolation which make up the shortage of the original passive vibration isolation and further improve the performance of the vibration isolation platen 本文基于大型空气弹簧隔振平台,研制出一种新型的主动隔振系统,有力地弥补原有被动隔振系统的不足,进一步提高隔振平台的性能。
In the end of the dissertation , a tube lifetime evaluation software system is developed with the utility of the finite element analysis stress computation and the metallographic tests . the lifetime of the platen superheater tube is evaluated by the software system 最后，综合以上应力解析法、有限元应力计算和余相试验研究开发了管件寿命评估软件系统，并使用该系统综合评估了屏式过热器管段的寿命。
Through measuring residual swhirling flow field in the flue duct of a real boiler , and analysing layout features of front and back platen supe - heaters in large - scale tangential firing boilers , the flue gas energy distribution regularity in horizontal flue duct of tangential firing boilers has been studied 摘要通过对实际锅炉烟道烟气残余旋转流场的测量及大型切圆燃烧锅炉前、后屏过热器的布置特点分析，研究了切圆燃烧锅炉水平烟道烟气能量的分布规律。
