According to operation characteristics of the main engine 9K98ME-C7, a combined turbines-exhaust gas waste heat recovery system is proposed to recover waste heat and increase system energy efficiency. Thermodynamic models based on the first thermodynamic law and the second thermodynamic law are formulated. The superheated steam yield, the total electric power yield, the first thermodynamic law efficiency, the exergy efficiency at different exhaust gas boiler working pressure, and the variation of the exergy efficiency under different feed water temperature and different steam turbine back pressure are analyzed. Thermodynamic results indicate that the most appropriate exhaust gas boiler pressure is 0.8MPa for studied main engine and the total thermal efficiency with combined turbines arrangement has climbed up to 53.8% from 48.5%
Paramedetera elongata sp. nov. from China is described and illustrated. A key to the species of the genus from China is presented.
We applied decoupling relationship analysis in this study to explore the relationship between agricultural carbon emissions and agricultural economic growth using data from Hotan prefecture in 1999-2013. The results demonstrated: 1. During 1999-2013 the decoupling index between agricultural carbon emissions and agricultural economic growth showed a “decoupling, hooking, and decoupling” three-state process. This was in the relative decoupling stage between 1999 and 2004, the relative hook state between 2005 and 2009, and the relative decoupling stage between 2010 and 2013. According to the elastic index, the relationship was in a strong decoupling state between 2000 and 2002, a weak decoupling state between 2003 and 2004, an expansive negative decoupling state between 2005 and 2009, and a weak decoupling state between 2010 and 2013. 2. Hotan is an area whose carbon emissions intensity is higher than that of the China and Xinjiang regions, is a serious lag on the decoupling stage to the nation and the region, and cannot achieve its agricultural carbon emission reduction targets by 2030. Therefore, a low carbon agriculture economy is the best strategic choice to develop its economy and address global climate change in Hotan. Thus, we have proposed policy recommendations including the establishment of a low carbon sense, the change of agricultural development way, the development of agricultural S&T, and the establishment of an incentive mechanism.
The following five species of the genus Dioides from China are described as new to science: Dioides furcatus sp. nov., Dioides incurvatus sp. nov., Dioides jinxiuensis sp. nov., Dioides minutus sp. nov. and Dioides rufescinasus sp. nov. A key to separate them is presented.
Agriculture is one of the main sources of anthropogenic greenhouse gases on the earth, but it also serves as a carbon sink, which has great potential for greenhouse gas absorption. Based on the scientific calculation system of carbon emissions and carbon sinks in agriculture, we calculated the carbon emissions and carbon sinks of agriculture using data from Hotan Prefecture for the period 1999-2014. The results showed that the net carbon sink (total carbon sinks and total carbon emissions) showed a stable increase trend in Hotan during 1999-2014. The carbon sinks level of agriculture in Hotan prefecture is more than three times of that in China and more than two times that in Xinjiang. Thus, the agricultural carbon sinks function of Hotan is obvious. To realize sustainable agricultural development and to transform agricultural carbon sinks into the power to promote regional economic development, we established the ecological compensation mechanism of agricultural carbon sinks from the aspects of the main body of compensation, compensation principle, compensation method, and compensation standard within the premise of the ecological function of carbon sinks in agriculture. We use the net carbon sinks amount multiplied by the unit price of carbon sinks to obtain the amount of agricultural carbon sinks compensation in this paper. Compensation methods include government compensation and market compensation. Government compensation mainly comprises financial, material, policy, and technical compensation. Market compensation mainly uses the carbon trading platform to compensate for the net carbon sinks of agriculture.
