多媒体时代我们怎样从事新闻事业     

张莘  赵海鑫 《传媒》2000,(1):24-25,7

现今所谓的“第四媒体“,即网络传媒,已经对印刷出版物构成了威胁,其内容的广泛性、大容量,势不可挡地从纸媒体手中夺走读者群。而其快捷性和低成本优势,更令纸媒体望尘莫及。 就拿报道北约导弹袭击我驻南大使馆事件来说,网络传媒充分展现了其天生的优势。北京时间1999年5月8日凌晨5时45分,北约的3枚导弹悍然袭击我驻南大使馆。仅仅42分钟后,中国的普通老百姓即从互联网上知道了这一骇人听闻事件。和1998年的美国空袭伊拉克  相似文献   

牛官     

赵海鑫 《孩子天地》2005,(5)

暑假,我回农村老家体验生活,让我受益非浅,感受颇多。回老家的第二天,舅家的孩子,小名叫大海,比我长两岁,安排我来当官。需要说明的是,这官不是管人的,是管牛的牛官,说白了就是当放牛娃。放牛,在农村是一件极为平常的事,但对城市的孩子来说,就很稀奇而有趣了。那天,我们是四个牛官,老爷、二老爷、哥哥和我。当牛官,首先要有统揽全局的本领--就是什么地方草好,什么地方草差,什么时候  相似文献   

Grindability,grading and wettability of recycled plaster     

李志新  彭家惠  赵海鑫  邱星星  赵敏 《天津大学学报(英文版)》2016,22(5):480-485

The changes of grindability, grading and wettability of recycled plaster(R-P)and the mechanisms of these changes were studied by using vickers hardness, particle size distribution(PSD), scanning electron microscope (SEM) and nitrogen adsorption porosimetry to reveal that R-P was obviously different from plaster of Paris(POP). At the same milling time, R-P had the characteristics of high specific surface area, fine particle diameter and uneven size distribution compared with POP, so R-P possessed both good grindability and poor grading. The water absorption, dissolution rate and mass loss in dry-wet cycle of the hardened recycled gypsum(hardened RG) increased, while the water saturated strength and dry-wet cycle strength decreased significantly compared with the hardened virgin gypsum(hardened VG). Therefore, poor wettability could be seen in R-P. The analyses indicated that the changes of grindability and grading could be attributed to the reduction in hardness and the increase in the porosity of hardened RG and that the poor wettability of R-P was caused by the increase of large pores and the changes of microstructure of hardened RG.  相似文献
