The relationships between the sulphide capacity index and the optical basicity, the mole fraction of oxygen ion and the Bell's ratio were investigated based on extensive lab scale equilibrium and industry scale quasi-equilibrium experimental data in the temperature range of 1300 1600℃. Although the sulphide capacity index has good relations with different representations of slag basicity. according to the data obtained under the lab scale equilibrium experimental conditions,the similar relations do not exist according to the data obtained under the industry scale quasi-equilibrium experimental conditions. So it is concluded that the sulphide capacity index, which has been considered as a measure of the slag basicity. can not be used for virtually all oxide slags of interest in the field of ironmaking and steelmaking. 展开更多

The national innovation capacity(NIC) has received increasingly more attention from academia and policy makers. This study develops a methodology for measuring NIC with a view to provide the evidence for policy-making concerning national innovation capacity-building, and conducts a crosscountry comparison based on the panel data of 2006-2015.(1) National innovation capacity index(NICI) is established to measure the performance of NIC from two perspectives, namely national innovation strength index(NISI) and national innovation effectiveness index(NIEI).(2) Developed countries usually perform better than developing countries in terms of the NICI if there is no huge gap in economic scale between two kinds of countries.(3) Emerging countries show greater imbalance between the NISI and the NIEI, and have generally higher average annual growth rate of the NISI and the NIEI than that of developed countries.(4) National innovation strength is closely related to national economic scale while national innovation effectiveness is closely related to national development level. Some theoretical considerations in this research may make contributions to innovation development studies.(1) NIC is regarded as the capacity for scientific discovery and technology invention, and for driving economic, social and environmental development, which emphasizes the driving effect and the influence of innovation on development.(2) The concepts such as the NISI and the NIEI are introduced to measure the NIC so as to distinguish the contribution of the size of innovation activities to the NIC and the contribution of the efficiency and efficacy of innovation-driven development to the NIC.(3) The indicator system of the NICI is designed from the perspective of the full spectrum of capacity-building process ranging from input to output by introducing the "innovation condition" as a broad sense "innovation input" and the "innovation outcome" as a broad sense "innovation output". 展开更多

Research on the carrying capacity and security of water resources is vital for its contribution to implementing sustainable development goals. The limitation of water resources is one of the most important factors that influence the sustainable utilization of resources. Studying the carrying capacity of water resources will not only facilitate monitoring and forecast of national resources and environmental carrying capacity, but also be valuable for building ecological civilization. According to the principles of evaluation system, the carrying capacity of water resources on Shandong peninsula is explored. A comprehensive evaluation model of the carrying capacity of water resources is constructed based on the carrying capacity of water resources index and the composite of water resources index. The results show that the capacity of water resources on Shandong peninsula is generally consistent with overexploitation, and that the development and utilization of water resources has reached a considerable scale under existing economic and technological conditions. The carrying capacity of water resources in this region is relatively small, and the contradiction between supply and demand of water resources is alarming. Relative countermeasures are put forward, to improve the water resources carrying capacity and to provide a basis for future sustainable development and utilization of water resources in this region. 展开更多

With population growth and increasing pressure on land resources,land carrying capacity(LCC) and food safety have been attracting great attention worldwide.From the point of man-grain relationship and by establishing LCC and land carrying capacity index(LCCI) models,this article firstly analyzes the spatial-temporal dynamics of LCC of China from 1949 to 2005 at county,provincial and national levels.Choosing 2005 as a representative year,this article then evaluates the LCC of 264 pastoral regions(semipastoral regions),663 urban regions and 592 poverty stricken regions of the country.The results show that:(1) from 1949 to 2005,with the increase of grain production,the LCC of China has been improved conspicuously,but due to the rapid population growth,the production can only maintain a low level grain consumption;(2) over the past 25 years(1980-2005),the number of population overloading provinces decreased from 23 to 15 and the mangrain relationship has been improved gradually,but there were more overloading provinces than surplus provinces in China;(3) at county level,there were 1572 overloading counties in 1980 accounting for 68.26% of the total counties of the country and where were 649 million people lived,while in 1990,2000 and 2005,the number of overloading counties were 1066,1133 and 1087 respectively,which shows that the man-grain relationship has been improved obviously during the past 25 years;as for spatial distribution,the surplus counties were mainly concentrated in agriculture developed regions,such as Northeast Plain,North China Plain,middle and lower Reaches of the Yangtze River Plain,and overloading counties were mainly located in regions with poor natural environment and low grain production capacity,such as Northwest China,Tibetan Plateau and Loess Plateau and economically developed urban regions,such as Beijing,Tianjin and Shanghai;(4) animal husbandry improved greatly the LCC of pastoral and semi-pastoral regions,while urban regions were overloading for increasing population pressure and more than half of poverty stricken regions were overloading due to critical natural environment and poor economic conditions. 展开更多

According to the relevant data about the land resources and population in Liaocheng City from 1999 to 2008, by using the research method of bearing capacity of natural resources, the thesis analyzes the relationship between natural resources and dynamic change of population in Liaocheng City. The results show that the farmland tends to diminish on the whole, and forests, garden land, urban-rural settlements and land for enterprises and mining increase slowly. Based on the analysis of the dynamic relationship between land resources and population, we conclude that the land resources still can bear the current population in Liaocheng City, but the population development inflict critical pressure on the forest resources and water resources. 展开更多

It’s necessary to forecast the shortest spontaneous combustion period for preventing and controlling the coal spontaneous combustion.During the experimental process,a calculating model of the SSCP is established on the basis of the oxidative heat release intensity and thermal capacity at different temperatures.According to the basic parameters of spontaneous combustion,heat of water evaporation and gas desorption,the SSCPs of different coals are further predicted.Finally,this study analyzed the relationships of the SSCP and the judging indexes of the self-ignite tendency.The result shows that the SSCP non-linearly increases with the decrease of dynamic oxygen adsorption and increase of activation energy.Compared with the practical fire situation of mine,this reliable method can meet the actual requirement of mine production. 展开更多

In Asia, the rice crop sustains millions of people. However, growing demand for this crop needs to be met while simultaneously reducing its water consumption to cope with the effects of climate change. Lowland cropping systems are the most common and productive but have particularly high water requirements. High-yielding rice genotypes adapted to drier environments(such as rainfed or aerobic rice ecosystems) are needed to increase the water use efficiency of cropping. Identifying these genotypes requires fast and more accurate selection methods. It is hypothesized that applying a new quantitative selection method(the score index selection method), can usefully compare rice yield responses over different years and stress intensities to select genotypes more rapidly and efficiently. Applying the score index to previously published rice yield data for 39 genotypes grown in no-stress and two stress environments, identified three genotypes(ARB 8, IR55419-04 and ARB 7) with higher and stable yield under moderate to severe stress conditions. These genotypes are postulated to be better adapted to stress environment such as upland and aerobic environments. Importantly, the score index selection method offers improved precision than the conventional breeding selection method in identifying genotypes that are well-suited to a range of stress levels within the target environment. 展开更多

A balanced ecological carrying capacity and its understanding are important to achieve sustainable development for human kind.Here,the concept of ecological carrying capacity has been used for measuring the dependencies between human and nature.China's ecological balance between supply and demand has become a global concern and is widely debated.In this study the 'Ecological Footprint' method was used to analyze the supply-demand balance of China's ecological carrying capacity.Firstly,the ecological supply and demand balance was calculated and evaluated,and secondly,the ecological carrying capacity index (ECCI) was derived for each county of China in 2007,and finally this paper systematically evaluated the ecological carrying capacity supply-demand balance of China.The results showed that ecological deficit appeared to be the main characteristic of ecological carrying capacity supply-demand balance in 2007 of China at county scale.In general,more than four-fifths of the Chinese population was concentrated in less than one-third of the land area and more than two-thirds of the land area was inhabited by less than one-fifth of the population.The spatial distribution of the ecological carrying capacity demand-supply was unbalanced ranging from significant overloading to affluence from southeastern to northwestern part of China.It appeared to be more dominant in regions located at coastal areas which are attracted by migrants and had a generally higher population density.Along with the rapid development and urbanization trends in China,ecological deficits in these regions will become more severe. 展开更多

Daily and annual average atmospheric environmental capacity coefficient(A-value) sequences for China's Mainland are calculated from hourly data recorded at 378 ground stations over 1975–2014. A-values at different recurrence intervals are calculated by fitting the sequences to Pearson type III distribution curves. Based on these A-values and source-sink balance(reference concentration 100 μg m^(-3)), atmospheric environmental capacities at the recurrence intervals are calculated for all of China's Mainland and each provincial administrative region. The climate average atmospheric environmental capacity reference value for the entire mainland is 2.169×10~7 t yr^(-1). An urban atmospheric load index is defined for analyses of the impact of population density on the urban atmospheric environment. Analyses suggest that this index is also useful for differentiating whether air quality changes are attributable to varying meteorological conditions or variations of artificial emission rate.Equations guiding the control of unorganized emission sources are derived for preventing air quality deterioration during urban expansion and population concentration. 展开更多

OBJECTIVE:To examine the clinical effects of a mixture of Chinese Yam and Epimedium in patients with stable moderate or severe chronic obstructive pulmonary disease(COPD).METHODS:Forty-nine patients with COPD were randomly allocated to a group whose usual treatment was supplemented with oral Chinese Yam-Epimedium mixture,or a control group given placebo.For each patient,body mass index,airflow obstruction,dyspnea,and exercise capacity were measured and converted into the BODE index before treatment and at one and three months after initiation of treatment.Participants also completed the St George's Respiratory Questionnaire(SGRQ) at the same intervals.RESULTS:After one month,improvements were seen in the BODE index and SGRQ of participants taking Chinese Yam-Epimedium mixture compared to controls.There were statistically significant differences in the SGRQ:three of its components and the total SGRQ scores were significantly decreased(P<0.05),respiratory symptom scores had improved(P<0.01),and the dyspnea component of the BODE index had significantly decreased(P<0.05).Similar improvements were observed after three months of treatment,but exercise tolerance had also improved:the six-minute walking distance had significantly increased(P<0.05) in the treatment group when compared with controls.CONCLUSION:Chinese Yam-Epimedium mixture can significantly improve dyspnea,exercise capacity,and the quality of life of patients with stable moderate or severe COPD. 展开更多
