《人民日报》献礼70周年新媒体产品传播分析——以《70年，我是主角》为例

新中国成立70周年,人民日报纸媒与新媒体平台共同发力致敬伟大时代,新技术结合新思路,传播主流媒体声音,出现了一批优秀的新媒体产品。本文以微电影《70年,我是主角》为例,通过分析视频的表现形式、叙事手法、画面节奏和情感诠释,探究其创新之处,以期为我国主流媒体微视频传播发展提供参考。

70年来的断想

育才建校70周年了。当年的莘莘学子，如今已是耄耋老人。缅怀从前，感叹万千。

Interaction of temperature and salinity on the expression of immunity factors in different tissues of juvenile turbot Scophthalmus maximus based on response surface methodology

Central Composite Design(CCD) and response surface methodology were used in the experiment to examine the combined effect of temperature(16-28℃) and salinity(18-42) on Hsp70 and IgM genes expression levels in turbot(Scophthalmus maximus) liver and kidney.The results showed that the coefficients of determination(R^2=0.965 2 for liver Hsp70,0.972 9 for kidney Hsp70,0.921 for liver IgM and 0.962 1 for kidney IgM) and probability values(P<0.01) were significant for the regression model.The interactive effect between temperature and salinity on liver Hsp70,kidney Hsp70 and liver IgM were not significant(P>0.05),while the interactive effect between temperature and salinity on kidney IgM was significant(P<0.01).The model equation could be used in practice for forecasting Hsp70 and IgM genes expression levels in the liver and kidney of juvenile turbot via applying statistical optimization of the response of interest,at which the maximum liver Hsp70,kidney Hsp70,liver IgM and kidney IgM of1.48,1.49,2.48,and 1.38,respectively,were reached.The present model may be valuable in assessing the feasibility of turbot farming at different geographic locations and,furthermore,could be a useful reference for scientists studying the immunity of turbot.

70多年前我大街上看热闹

70多年前的民国时期，我还是个10来岁的孩子。那时候浙江家乡武义县城只有一条街，人们称它为“街路”。当时家住小巷里的我，常常觉得日子过得太平淡，周围环境太安静，只有到街路才可以看到各种各样的热闹。可是母亲对我实行“封闭式管理”，不准我随意走出家门一步，不用说上街路了。
