问题 问答题

某地区政府部门委托某工程咨询公司对本地区的能源利用状况进行市场调查,调查统计的该地区2013年能源消耗和产值情况见表5-1。

   为了资源的可持续利用,该地区政府部门要求到2018年该地区能源消耗总量控制在700万吨标准煤以内,并据此制定相应的5年规划。   按照目前发展思路,初步规划方案预计2018年该地区各类用户的数量分别达到:居民家庭150万户,工业企业2.3万户,服务企业1.4万户,其他行业0.3万户,机关事业单位数量不变。   问题:

按照地区政府部门对2018年能源消耗的控制要求,依据目前该地区能源消耗和产值状况,量化分析该地区的产业能源消耗结构和产业产值贡献比例,并分析两者的关系。

答案

参考答案:

产业能源消耗结构

居民家庭:100/640=15.62%

工业企业:500/640=78.13%

服务企业:30/640=4.69%

其他行业:8/640=1.25%

机关事业单位:2/640=0.31%

产业产值贡献比例

居民家庭:0

工业企业:250/980=25.51%

服务企业:600/980=61.22%

其他行业:80/980=8.16%

机关事业单位:50/980=5.10%

工业企业占能源消耗的很大比例78.13%,但相应的产值贡献率仅为25.51%,能耗产值贡献较差;服务企业占能耗比例4.69%,但是却贡献了61.22%的产值。

Jack was so excited about getting a new backpack because his old one had a broken zipper(拉链) and a hole in the bottom.

Jack’s elder brother took him to buy a new backpack. There were so many cool ones. How would he ever decide? He saw blue ones—his favorite color. He saw ones with his favorite action hero on the front. And then Jack saw a backpack with a black square design. When he opened it, he saw it had a hidden, secret small bag. He liked it, which made it different from others.

“This is the one,” he said, then carried it to the check-out counter.

That evening, Jack carefully filled his new backpack with his school things. He put his special pen in the secret small bag. The next day in English class, Mr. Mack said, “Let’s write an essay about earthquakes!” Jack looked for his pen in his backpack, but he couldn’t found it! He rummaged through his desk and his pockets, but no pen.

Jack asked if anyone had seen his pen, but no one had. Mr. Mack lent him a pencil, but Jack was feeling anxious because he lost his pen. When he got home, Jack told his brother he couldn’t find his favorite pen. His brother said, “You must have put it in that secret small bag.”

Jack laughed and said, “That small bag was so secret that I forgot all about it.”
