In addition to these, a system identification computer program for the chain grate stoker was developed as well. After that, the system identification techniques based on PRBS and program was applied to an industrial-scale boiler. Practice shows that this method is easy and feasible. It could provide the theory model for the design and upgrading of the boiler's control system.

结合某20t/h链条工业锅炉的现场试验数据，利用该方法及其对应的程序对锅炉动态特性进行了建模，经验证，该辨识模型具有较高的可信度，可为锅炉控制系统设计和优化升级提供相应的理论基础和科学依据。

The gas solid interaction was studied, the solid concentration and particle size distribution contours downstream of the nozzle were obtained. The particle roping mechanism in a coal conveying pipe with large diameter was also studied with the fiber probe. The on-line coal concentration measuring facility is needed for NO〓 reduction. In this work, a set of on-line coal concentration measuring facility was developed and installed in the coal conveying pipes of a 660MW capacity utility boiler, which can give on-line accurate coal concentration information for the operator.

论文首次采用基于光学波动法的激光光纤探针，对高浓度的低NO〓燃烧器出口的气固两相流动的详细结构进行了试验，研究了配300 MW煤粉燃烧锅炉的燃烧器出口高浓度气固相射流中颗粒浓度、粒度随射流发展的演变规律，分析了利用水平浓淡燃烧器和齿形燃烧器实现对低NO〓燃烧有利的气固结构，并验证了基于DES方法的气固两相数值模拟的计算结果。

The existence of Kaiser effect was verified under Brazilian tests conducted on coarse-grained granite.

验证了粗晶花岗岩在劈裂试验条件下凯塞效应的存在性。

Secondly, most of the constitutive relations of SMA, which have been established before, are so complex that they cannot be used to calculate in the design of SMA springs. In this paper, it puts forward to an easier mechanical constitutive relation of SMA spring, which is fit for designing. Its applicability has been proved by the experiment which includes SMA spring compression and uninstall.

其次针对以往从机理分析建立的形状记忆合金力学本构模型过于复杂、不适合工程设计计算的缺点，建立了简单的SMA弹簧的力学本构模型，通过对形状记忆压簧的压缩、卸载试验，来验证了这个模型的适用性，并与其它文献的实验结果相比较，二者结论基本一致。
