Cimaterol has a higher solubility than that of mabuterol. The experimental data of solubility were correlated by four density-based models.The correlation accuracy highly depends on the system investigated, which is mainly determined by the density ranges and temperature.展开更多

[ Method] The mice were randomly divided into experimental groups and control group. The mice in the experimental groups were respective- ly administrated with pST and liposome-encapsulated pST via intraperitoneal injection, and those in the control group were administrated with saline. They were weighed on Day 7, 14 and 28, and the growth rate was calculated. [ Result] The growth of mice had significant difference between the experiment groups and control group （P 〈 0.05）, which indicated that the pST and liposome-encapsulated pST had growth-promoting effects in mice, and the liposome-encapsulated pST had sustained-release effects. [Condusion] The liposome-encapsulated pST can promote the growth of animal and its sustained-release peried is 7 d.展开更多

This paper tries to find the answers to two questions. Firstly, what are the main similarities between music and language？ Secondly, in what aspects can music facilitate language similarities （sound, rhythm, and acquisiti structure on？ By literature reviewing, comparison and contrast, three main ） between music and language are discussed, and then three facilitative effects of MAD on language acquisition are illustrated. They are： （1） MAD lays a foundation for language pronunciation acquisition; （2） MAD accelerates the mastery of language rhythm; and （3） MAD promotes language syntax acquisition. This paper will help teachers who like to use music-assistant language teaching method understand more about the positive effects of music on language teaching and acquisition.展开更多
