Authors: Yang Hengyi , Hou Mengnan , Cui Aoran 
Published: July 2020

Abstract
Existing research indicates that many countries are in danger of disappearing completely due to sea level rise. Therefore, many environmentally displaced persons (EDPs) will be generated. The number of these EDPs and the ways of resettling with humanitarianism are promising issues. Tuvalu is the fourth smallest country in the world, and its country has stated that it has plans to relocate the country, so it has attracted our attention. Firstly, assuming that the population of the area is not affected by sea level, establish block population growth model, predict the future normal population. At the same time, build the prediction model of BP neural network based on EMD to predict the future sea level, and the connection between the two models is time. When the sea level reaches a certain threshold, the area’s environment is no longer stable, and in this time the year when the threshold was reached and the corresponding population were determined. We use the analytic hierarchy process to evaluate the influences of various social policies on cultural loss risk, which can effectively adjust the policy and protect the diversity of culture. Accepting refugees to the society, economy and culture of a country is a great challenge. Later, we set up the secondary fuzzy comprehensive evaluation model, and a lot of impact factors are classified as economic, social, ecological and other categories. Standardize and normalize the data. Using the entropy weight method to determine the weight of each index. Give a score for every country, and countries or regions of high scores have the ability to accept the refugees. Last, we use the analytic hierarchy process to evaluate the influences of various social policies on cultural loss risk, which can effectively adjust the policy and protect the diversity of culture.

The Role of Sodium-alkali Waste Gas Washing and Desulfurization Technology in the Exhaust Gas Treatment of Marine Diesel Engines
Authors: Liang Ensheng 
Published: July 2020

Abstract
to reduce the concentration of sulfur oxide in the exhaust gas of marine diesel engines, the application of sodium-alkali waste gas washing and desulfurization technology in the exhaust gas treatment of marine diesel engines is explored. First, the reaction mechanism of sodium-alkali wet washing desulfurization technology is introduced, including the absorption process model of sulfur oxide, the absorption rate equation, the equation for absorbing sulfur oxide in aqueous solution, and the process of dissolving and absorbing sulfur oxide in sodium hydroxide solution. Then, a method to improve the absorption rate of sulfur oxides is proposed. Finally, the influence of load and pH of washing solution on desulfurization efficiency is discussed. The results show that the sodium-alkali waste gas washing and desulfurization technology has a good desulfurization efficiency. The desulfurization efficiency under different loads is more than 99%, and the maximum is 99.7%, which meets the desulfurization requirements of the national heavy oil exhaust gas treatment system. The higher the pH of washing solution, the more obvious the desulfurization efficiency. The results of this research provide a theoretical basis for the development of Chinese ships.

Authors: Wu Haoyu , Qiu Fengkai , Li Hongze , Zeng Ming , Sun Chenjun 
Published: July 2020

Abstract
This paper studies the relationship and differences between carbon emissions and industrial development in four countries with different development levels from a global perspective. First, the Tapio decoupling model was established, and the overall dependence of countries of various development levels on carbon emissions was analyzed from strong to weak. Then, establish a panel data model to study the influencing factors of carbon emissions in countries with different development levels from 2015 to 2019. The results show that the added value of industry and agriculture has a significant positive effect on carbon emissions in countries of various development levels, and forest area has a significant negative effect on carbon emissions. Developed countries are still the largest emitters. Therefore, industrial and agricultural production is still the most important factor affecting carbon emissions, and the increase in forest area helps reduce the impact of carbon dioxide.

Research and Design of Marine Trash Classification Robot Based on Color Recognition
Authors: Dong Xun 
Published: July 2020

Abstract
The UN (United Nations) identifies sustainable development of the marine ecosystem as a major goal. To achieve the goal, the garbage in the ocean has to be removed, and as people recognize that different types of classification should be disposed differently, classification is critical after garbage is collected. This led to the engineering goal of constructing a robot that can pick up garbage in the water and classify the garbage into its right category. The robot was developed by attaining four critical functions: driving under water condition, a set of gripper, color recognition and garbage classification. Results of data obtained from developing the garbage classification was plotted on multiple graphs including training and validation loss, training time, training and testing accuracy and so on. After the critical functions are fulfilled, it is shown that the accumulative testing accuracy for garbage classification algorithm was around 90.6%, while the programs for the other three critical functions all compiled successfully. It was a regret that datasets weren’t shaped to the same sizes and the critical functions should be synthesized for further research.

Published: July 2020

Abstract
This paper conducted an in-depth analysis on the characteristics of components of heavy metals in PM2.5 by studying the atmospheric heavy metal elements during winter in Chengdu. On the basis of the limiting value of heavy metal element concentration in PM2.5 in major cities at home and abroad and the national standard limiting value on heavy metal element concentration, this paper compared and evaluated the pollution level of heavy metal elements in PM2.5 during winter in Chengdu and analyzed the typical characteristics of heavy metal elements in haze days and non-haze days as well as the potential sources. The following conclusions were drawn: 1) in PM2.5 during winter in Chengdu, the major component was K, minor components were Fe, Ca, Zn, Cu, Pb, Ba, Mn, As, Cr and Cd, trace components were Se, Ag, Hg, Ni, V, Au and Ga and ultra-trace components were Co, Sb, Ti and Sn, and the proportion of the aforementioned components was 2.10706%, 2.14783%, 0.01933% and 0.00009% respectively; 2) the major component, minor component, trace component and ultra-trace component of heavy metal elements respectively accounted for 1.621%, 1.641%, 0.016% and 0.00004% of PM2.5; 3) the proportion of all the heavy metal components in PM2.5 in haze days was lower than that in non-haze days, which indicates that the relatively high concentration of PM2.5 might be caused by non-metallic salts; 4) in PM2.5, the proportion of Pb, Cd, Mn and Cu was lower than both the domestic average level and the international average level; the proportion of Zn and Ni was at the domestic average level but slightly higher than the international average level; and the proportion of As was at both the domestic average level and the international average level; 5) the mean value of Pb concentration during winter was 0.08717µg/m3, which was lower than the limiting value of the national standard GB 3095-2012; and 6) there was a rather high level of consistency between such elements as were K, Ca, Fe, Zn and Ag as well as PM2.5 on the typical haze day, which shows that obvious colinearity existed in the emission source of the aforesaid elements and such elements might come from road dust sources; on the typical non-haze day, random-peak daily variation occurred in heavy metal components, which might result from unorganized emission from peripheral pollution sources; however, the proportion of ultra-trace components of heavy metals on the typical non-haze day was slightly higher than that on the typical haze day, which might be closely related to the local background transmission.

Research on Method of the Flow Passage Condition Monitoring and Diagnosis for Steam Turbine
Authors: Wang Jiayong , Deng Debing , Zhao Qingsen , Xu Shiming 
Published: July 2020

Abstract
Monitoring and diagnosis of the steam turbine flow passage is the most important premise to achieve the power plant condition maintenance. The existing characteristic flow area of steam turbine changes with main steam flow and can not accurately reflect the flow passage state of steam turbine. In order to reflect the state change in turbine passage accurately, the characteristic flow area of steam turbine stage should be investigated in the same main steam flow. Because main steam flow on-line measuring method accuracy is deficient, a new method based on the exhaust pressure of IP cylinder as character parameter of main steam flow is proposed, and a correction method which takes the impact of the heat regenerative system on main steam flow into consideration is presented. Meanwhile, in the diagnostic process, the measuring result is strongly influenced by the system inevitable measuring error which directly affects the deviation between the characteristic flow area and its standard. Thus confidence intervals of characteristic flow area is given to eliminate the system errors. Finally, the actual diagnostic example in the article indicates the practicability of the method. It can be used to diagnose the flow passage of steam turbine and provide reliable basis to find out the steam turbine potential.
