To verify the feasibility of applying Neutral Regression Equations to retrieve Landsat8 sea surface temperature (SST), and compares the retrieval accuracy and difference of the two thermal infrared bands, this paper establishes Neutral Regression Equations based on 32 MODIS SST training points, and uses buoy SST and MODIS SST to validate and compare the retrieval results. The results show that the Landsat8 SST retrieved by these Equations has high accuracy and good consistency with MODIS SST. Buoy SST verification shows that the root mean square error ( rmse ) of the two bands is less than 0.5°C, and the deviations range is less than 1°C; MODIS SST verification shows that the mean deviation( bias ) of the 10 th and 11 th bands are -0.16°C and -0.22°C, respectively, and their deviations range is basically within ± 1°C; the retrieval accuracy of the 10 th band is higher than that of the 11 th band. Using Neutral Regression Equations to monitor the thermal discharge from Houshi Power Plant has achieved a wonderful effect, the temperature rise plume is jet-like, and affects a large range with a total area of 1.88km 2 and a maximum thermal pollution distance of 2.5km.

Healthy water environment is the prerequisite for river resource utilization, social and economic development, new urbanization and healthy and happy river construction. Through the literature database retrieval statistics, summarizes the river water environment research to numerical simulation analysis, environmental quality improvement direction. The indicator system, evaluation method and significance of river ecosystem health assessment, and water ecological security assessment are introduced in detail. Finally, the types of river water environment numerical models are summarized, and the advantages and disadvantages of mainstream models and their application conditions and characteristics are compared and analyzed. In order to provide basic reference for river water environment numerical simulation machine watershed ecological environment protection and maintenance.

Based on the BIM cloud service, in the green construction evaluation system, this paper introduces the sub-module and the overall architecture. In the sub-module, it includes auxiliary evaluation system, load balancing architecture, and data service. It is an effective method to store data. Through the conversion and integration of data storage methods of various computer protocols, the traditional green construction evaluation methods can be efficiently and accurately evaluated by cloud computing servers. At the same time, the database can hold a large amount of data and continue to expand.

With the ever-enhanced comprehensive national strength, China plays an increasingly important role on the international arena, and it has participated in more and more terminal projects on the African continent. By summarizing the three aspects of comparing basic parameters and technological parameters, this paper analyzes three practical projects of micromidi airport terminal buildings in Africa that were designed and constructed with Chinese participation. Finally, in the aspects of design standard, construction scale, service standard, technological process, the response of natural environment elements and the response of cultural elements, this paper compares and analyzes with the airport terminal in China. How to respond to the local cultures and realize the localization design was discussed when Chinese architecture marched into the world construction market.

In order to improve activity of the catalysts used in SCR DeNOx system of flue gas, a series of catalysts activated by different activating liquids under varied conditions in boiler directly were conducted. Then these catalysts were characterized by SEM, FT-IR and BET technology. And NO conversions of the activated catalysts were studied and compared with that of inactivated catalyst. The above experiment shows that NO conversion of the activated catalyst can be up to 99%, which 30% higher than that of inactivated catalyst, so activity of catalysts were improved greatly. Furthermore, optimal activating liquid labeled L2 and effective technology parameters were gained in the experiment.
