近年来,我国传统外语语言实验室管理模式受到高校外语语言实验室的冲击,高校外语语言实验室在教学和科研过程中显现出了重要作用,对提升教学质量具有重要意义.高校外语语言实验室管理模式的建立是在传统语言实验室管理模式基础上建立的,是对传统管理模式进行的科学合理的改革,对推动我国教学模式创新和提高教学质量具有重要意义.

The relation between sodium dehydroacetate and preservation quality of pickling pepper was studied by analyzing the effects of sodium dehydroacetate on fermentation and quality in preservation process.The results show that the increase speed and accumulation value of sodium dehydroacetate acidity during fermentation process of pickling pepper is lower than CK when sodium dehydroacetate is added in pickling pepper before fermentation and the fermentation process of pickling pepper is restrained when the concentration of sodium dehydroacetate is above 0.03%,and adding sodium dehydroacetate in pickling pepper during preservation can raise the acidity of sodium dehydroacetate and reduce loss of vitamin C,nitrite increases amount and the total colony number compared with CK and the better preservation quality can be obtained under adding above 0.03% sodium dehydroacetate during preservation.
