翻开近一时期的报纸杂志,有关PM2.5(细颗粒物)的报道十分抢眼,令人遗憾的是,绝大多数媒体都把后面的数字2.5写成了与前面PM同样大小。众所周知,H2O(水)、SO2(二氧化硫)等专业符号中的数字2绝对不能写成和前面的字母一样大小,但在这些PM2.5的报道中,几乎无一例外地写错了。在近年的媒体刊用稿件中还有诸多类似问题需要注意。
Newspapers and magazines that opened a period of time ago, PM2.5 (fine particles) is very eye-catching reports, it is regrettable that the vast majority of media have put behind the number 2.5 has been written in the same size with the previous PM. It is well-known that the number 2 in professional symbols such as H2O (water) and SO2 (sulfur dioxide) can never be written in the same size as the previous letter, but almost invariably in these PM2.5 reports. In recent years, there are many similar issues in the media coverage issues need attention.
