建立了蒸汽管道多层复合保温结构传热模型,采用DN200mm管道实验研究了不同保温结构和保温材料对隔热性能的影响,根据实验数据验证了数学模型准确性,并以此为基础给出了不同工况下最佳保温方案的确定方法。实验结果显示,管道表面热流密度随着对流层的加入和气囊层数的增加而降低,随披肩厚度和保温总厚度的增加逐渐降低,而反射层数量增加热流密度先降低后升高。传热模型预测结果与实验数据高度吻合,相差不到6%。从经济性分析,不宜采用对流层作为保温材料。最终确定的最佳保温方案能够显著降低系统的供热总成本,最优保温厚度值随管内介质温度和管径的增加而升高。对于温度大于400℃的高温管道,采用复合保温结构相比于单一硅酸铝保温可节省超过30%的投资。

第三十九届中国控制会议

作者： Zihao Guo Jian Tang Junfei Qiao haijun he Faculty of Information Technology Beijing University of Technology Beijing Key Laboratory of Computational Intelligence and Intelligent System

Municipal solid waste incineration（MSWI） is a widely used domestic waste resource treatment technology. However, this process products pollution dioxins（DXN）. It has high toxicity and durability. This is one of the main reasons of "not in my backyard" effect when constructing MSWI plant. As the long period and high cost of off-line DXN detection method, it is difficult to realize the real-time monitoring of DXN emission concentration. The massive unlabeled samples in the industrial field contain the generation mechanism of DXN, which are not fully utilized. Aim at the above problems, this paper proposes an unmarked samples and improved deep belief network（DBN） based method to construct DXN soft measurement model. Firstly, a large number of unlabeled samples are added to the training input sample set to improve the learning ability of soft measurement model at pre training phase. Then, an energy function is derived as the activation function of restricted Boltzmann machine（RBM）. Finally, for the whole DBN, dropout algorithm is used to improve the robustness of the model, and the adaptive learning rate error back propagation algorithm is used to fine tune the weight iteratively at the fine tuning phase. The validity and rationality of this method are validated by DXN data set.

Forensic Medicine and Anatomy Research 2016年第2期4卷 23-28页

作者： Qi Wang Lingyun Yang Yinming Zhang Yao Yao haijun he Zhenyuan Wang School of Forensic Science and Medicine Xi’an Jiaotong University Xi’an China Sanyuan Branch of Xianyang Public Security Sanyuan China

Blunt cardiac rupture is a characteristic of high death rates and rapid death process. But sometimes it is hard to find out the cause of cardiac rupture of traumatized patients, especially when it relates the relationship between injury and disease. In the 2 cases reported herein, both of the 2 patients had pre-existent cardiac pathological changes when suffered from traumatic injury. Our aim is to evaluate autopsy findings from a medicolegal point of view, and offer our proposals on how to deal with this sort of cases.

Furnace temperature is an important indicator to control and optimize the Municipal Solid Wastes Incineration（MSWI） process. However, limited by the environment and instruments, it is difficult to measure the furnace temperature online and accurately. In this paper, a TS fuzzy neural network is utilized to design the prediction model in MSWI process, trying to obtain the real-time and accurate measurement of the furnace temperature. First, the mechanism of the MSWI process is introduced in brief. Then, the structure and training method of the TS-fuzzy-neural-network-based prediction model is introduced in details, which helps to build the nonlinear relationship between the furnace temperature and other process ***, the designed prediction model is applied to a real MSWI plant, and simulation results demonstrate the effectiveness and outperformance of the proposed methodology.
