The total on advertising spent on the Chinese mainland last year rose by 25 per cent over 2003, a survey shows.

Expense reached US$23 3 billion, including television and print media, the survey/vas released by CTR Market Re-search on February 23, 2005.

The cosmetics and toiletries化妆品) sector was ranked No.1 in spending with US＄4.8 billion, an increase of 34 percent.

Advertising can be seen as the "weather glass" of the overall development of the country's economy, said Tian Tao, deputy general manager of CTR..

"The results of the survey reflect strong economic development in the country," Tian said.

"One of the most interesting-findings from the survey is that local and foreign mobile phone manufacturers reacted quite differently in terms of advertising spending," Tian said.

Most local mobile phone manufacturers had decreasing advertising expense while the foreign ones saw significant growth, Tian said.

Researchers also found that advertising on so called functional drink categories(种类) increased while milk makers decreased after a clear increase in advertising spending in 2003.

The survey also includes figures from Hong Kong and Taiwan, advertising expense in Hong Kong reached US $ 4.8 billion, an increase of roughly 15 per Cent from the previous year. Taiwan advertising spending reached US $15 billion, up roughly 27 per cent from the previous year.

In Hong Kong, the top three advertising categories were household and toiletries~ banking and investment services, and cosmetics.

In Taiwan, the top three advertising categories were real estate(房地产) , automobile and financial institutions.

生产甲醇的原料CO、H₂可由下列反应制取：CH₄（g）+H₂O（g） CO（g）+3H₂（g），试回答下列问题。

（1）已知：① CH₄（g）+3/2 O₂（g） CO（g）+2H₂O（g）△H_l；

② H₂（g）+1/2 O₂（g） H₂O（g） △H₂，

则CH₄（g）+ H₂O（g）CO（g）+3H₂（g）的△H＝____     （用含△H₁，△H₂的式子表示）

（2）一定条件下反应CH₄（g）+H₂O（g）CO（g）+3H₂（g）中CH₄的平衡转化率与温度、压强的关系如图，且T₂>T₁， 则上述反应的△H____    0（填“<”、“>”、“=”，下同），A、B处对应平衡常数（K_A、K_B）的大小关系为K_A____       K_B

（3）维持温度T₂，将0.04 mol CH₄和0.04mol H₂O（g）通入容积为1L的定容密闭容器中发生反应，平衡时达到B点，测得CH₄的转化率为50%,该反应在此温度下的平衡常数K_B=____  ，下列现象能说明该反应已经达到平衡状态的是_    ___

a．容器内CH₄、H₂O、CO、H₂的物质的量之比为1：1：1：3

b．容器的密度恒定

c．容器的压强恒定

d．3υ_正（CO）＝υ_逆（（H₂）

（4）在上述B点平衡基础上，向容器中再通入amol CH₄和a mol H₂O气体，使之在C点重新达平衡，此时测得CO有0.03mol，则a=____         。
