structure density造句

abstract : based on the test results of frost micro pore structure density distribution of high strength concrete at minus temperat ure ( hscmt ), the frost damage fiber bundle model of hscmt was buitl . the purpose is to study frost damage factor of hscmt in the future, to deduce lost efficiency p robability of hscmt and prevent hscmt from frost in cold weather
