The Comparion of Thermal economy Cogeneration Between Winter and Summer The thermal economy, which signifies the energy-saving ability of a power plant, is the key factor in analyzing energy utilization rate.
According to related material, currently, the big-scale coal-firing cogeneration of our country can reach a thermal efficiency as high as 85%[6], compared to which the thermal efficiency of straw power generation products is still low.

Preparation and Characterization of Ni-Modified Fe-Mo and Catalytic Selective Oxidation of p-Xylene Zu-Zeng Qin1,2, Zi-li Liu1, a, Yan-bin Liu2, Rui-wen Liu2 1 School of Chemistry and Chemical Engineering, Guangzhou University, Guangzhou 510006, China 2 School of Chemistry and Chemical Engineering, Guangxi University, Nanning 530004, China a Corresponding author.
Therefore, the green process of TPAL preparation has gradually become a hot spot. it uses the selective catalytic oxidation as the method, PX as the raw material, and oxygen or air as the oxygen source[2].
The key in the partial oxidation of PX to TPAL is the preparation process of the catalyst.

Phytoremediation is a green remedial engineering technology to repair polluted soil, and serves as a hotspot of technological research on the integrated remedy of environmental pollution[2].
Material and Methodology 1.1 Experimental Samples Samples for experiment are taken from Huanggua Mountain in Yongchuan District of Chongqing City.

Characteristics of Electromagnetic Waves Propagation in Corridor for High-rise Buildings Li Xiang-Jiang 1, Fan Jing 2 1.International Education College, Nanyang Institute of Technology, Henan Nanyang, China 473004 2Department of Electronics and Electrical Engineering, Nanyang Institute of Technology, Henan Nanyang, China 473004 lixiangjiang_111@163.com Keywords: high-rise building; electromagnetic wave; rectangular dielectric waveguide; propagation characteristics Abstract: With the popularity of wireless communication systems, the question of radio signal coverage is getting more and more attentions in corridor for high-rise buildings.
The four bands, 210MHz, 460MHz, 1.2GHz and 2.0GHz, are chosen as the key frequency bands for measurement.
Based on the experiment, when the frequency is higher than 2.0GHz, its transmission is much influenced by personnel's movement and metal material, and that the signal stability problem need to be carefully considered.
Because of more and more attention given by public on the problem of radio signal coverage in indoor buildings, this study [12] provides the theoretical guidance for the majority of engineering and technical personnel for the design and installation of the indoor wireless communication system.
