答案:

参考答案:

通电后如果出现全网路不爆时,爆破工应立即用欧姆表检查网路,出现三种情况分别放炮处理:

(1)若表针读数小于零,说明网路有短路处,这时应依次检查导线,查出短路并处理后,重新通电起爆。

(2)若表针走动小,读数大,说明有联接不良的接头,电阻大,此时应依次检查联线接头,查出后,将其扭结牢实,重新放炮。

(3)若表针不走动,说明网路导线或雷管桥丝有折断,此时需要改变联线方法,采用中间并联法,依次逐段重新放炮,或一眼一放,查出瞎炮后,按瞎炮处理规定予以处理。

When important events are happening around the world, most people turn to traditional media sources, such as CNN and BBC for the news.However, during the war in Iraq in 2003, many people followed the war from the point of view of an unknown Iraqi citizen who called himself “Salam Pax ” .(Salam Pax means peace)

Salam Pax wrote a diary about everyday life in Baghdad during the war, and posted it on his website.Pax’s online diary was a kind of website known as a “blog”.Blogs are online diaries, usually kept by individuals, but sometimes by companies and other groups of people.They are the fastest growing types of website on the Internet.

A blog differs from a traditional website in several ways.Most importantly, it is updated much more regularly.Many blogs are updated every day, and some are updated several times a day.Also, most blogs use special software or websites, which can help ordinary people easily set up and start writing their own blogs.

There are many different kinds of blogs.The most popular type is an online diary of links where the blog writer surfs the Internet and then posts links to sites or news articles that they find interesting , with a few comments about each one .Other types are personal diaries, where the writer talks about their life and feelings.Sometimes these blogs can be very personal.

There is another kind of blogging, called “moblogging ”, short for “ mobile blogging ”.

Mobloggers use mobile phones with cameras to take photos, which are posted instantly to the Internet.The use of mobile phones in this way made the headlines in Singapore when a high school student posted a movie he had taken of a teacher shouting at another student on the Internet.Many people were shocked by what the student did, and wanted phones with cameras to be banned from schools.

Many people think that as blogs become common, news reporting will rely less on big media companies, and more on ordinary people posting news to the Internet.They think that then the news will be less like a lecture, and more like a conversation, where any one can join in.
