Test results show that gradation 1 and gradation 4,gradation 2 and gradation 3 have the similar performance of frost resistance; the frost resistance coefficient of the former is about 40% when the cycle of freezing and thawing is 50 and the coefficient of the latter is still larger than 70% when the cycle is 100.Besides,the former is much smaller than the latter and the frost resistance coefficient decreases with the increase of cycle of freezing and thawing.
This paper systematically deals with the formation and changes of the theme of “depth emotion” in The Peony Pavilion,traces the theme to its historical origin,and reveals its ethical values and philosophical meanings that were not presented in other similar plays,thus providing a new theoretical perspective for the reading of it.
The results of taking the design and construction plan of pile foundation static load experiment for bridge of south-north water transfer as an example and adopting slow speeded load method to explain the relationship between load and displacement,can give reference for similar engineering.
The concentration, production intensity and yield to glucose of pyruvic acid reached 80.51g/L, 1.83g/L·h and 0.69g/g in 7L-jar fermentation, which were 44.36%, 57.48% and 22.78% higher than the control results respectively. The numbers has reached to or even surpassed the best international results ever reported using the similar strains.
In this paper,we give two new sufficient and necessary conditions for Banach spaces to be K-strictly convex by using Hahn-Banach continuation theorem and the number which is similar to K-dimensions volume.
