The human settlement environment is a dynamic subsystem in which people live, produce and live in the social system, and is constantly evolving. Aiming at how to comprehensively evaluate the suitability state of a given human settlement environment in a certain time and space and the evolutionary trend of this state, the set pair analysis theory and its partial connection numbers are introduced into the suitability evaluation of human settlements, and the set of human settlements is established. Analyze and evaluate the model and apply it to the suitability status and development trend of human settlements in Jiangxi Province from 2013 to 2016. The results show that the suitability of the province from 2013 to 2016 is between excellent and good, and it is going every year. The direction of more livable development, the intensity of development trend is between 0.5 and 0.53, suggesting that the relevant government decision-making departments need to continuously increase the investment in the livability of the province's human settlements, and ensure that the environmental livability is not weakened.
The effects of aminosulphonic acid-based Superplasticizer(ASP)on the fluidity of cement paste and harden perfomance and mechanical performance of fresh concrete are studied.The water reducing rate, adaptation to cements and compatibility with naphthalene-based water reducer of ASP are tested. Teating results indicated that in comparison with naphthalene-based water reducer, ASP has the characteristics of low cost, highly effective water reducing ability and the ability restraining slump loss, and also has excellent adaptation to cements and good compatibility with naphthalene-based water reducer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
