14世纪，欧洲旅行家马可•波罗在他的《东方见闻记》中曾描述：“中国人的燃料是一种黑石头…”他所说的燃烧的“黑石头”就是煤．其实，在他见到中国人用煤以前，中国人已经用煤一千多年了．煤是一种重要的化工原料，用煤作燃料，不仅是极大的浪费，而且因烟煤中含有硫的化合物（如FeS₂），燃烧会产生SO₂而污染环境．

若煤中含FeS₂5%，假设燃烧时硫全部转化为SO₂而排入大气中，其燃烧化学方程式如下：

4FeS₂+11O₂

（1）我国计划从2001年至2005年，将SO₂排放量从每年1995万吨降至1800万吨，意味着2005年比2001年可少燃烧这种煤多少万吨？

（2）为了消除SO₂对空气的污染，可用烧碱溶液吸收．那么2005年比2001年可以节约烧碱固体多少万吨？

For millions of Chinese Internet users, the penguin is more than a flightless bird from the Antarctic. To them it is the symbol of QQ, the instant-messaging service marking its 10th anniversary.

QQ’s creator, Ma Huateng, 38, is a lover of stargazing, and describes himself as a combination of idealist and realist. “ I’m introverted. My friends believed I was too shy to find a girlfriend,” Ma said. He found a girlfriend, now his wife, through chatting online on QQ. Born in Hainan province, Ma loved watching stars and dreamed of becoming an astronomer. He moved to Shenzhen, along with his parents, in southern Guangdong province when he was in his teens. Ma was impressed by the slogan “ Time is money, efficiency is life” found all over the city. It was the most famous slogan born in Shenzhen, representing China’s reform and opening. The pioneering city provided chances for Ma to watch burgeoning reforms. He saw people carry big bags of cash to buy stocks after China launched a capital market in Shenzhen and Shanghai in the late 1980s. When he graduated from Shenzhen University in 1993, Ma designed a stock exchange software system and sold it for 50,000 yuan ($ 7,3000). He then worked as an IT engineer for five years.

It was in 1998 that Ma realized Internet would transform China and the world, and launched his own company, Shenzhen Tencent Inc. A unit of Tencent, Tencent Holdings Ltd, went public on the main board of the Hong Kong Stock Exchange in 2004. “ China’s reform and opening provided me with a chance to grow the company,” Ma said. The country had only 3 million Internet users when QQ made its debut in 1999, but now China has around 300 million Internet users, Ma said. Hu Qiheng, chairwomen of the Internet Society of China(ISC), said reform and opening not only improved people’s living standards, but also gave them a chance to explore the outside world and a chance for the Internet to boom in the country.

It was in the late 1990s that China’s major Web portals mushroomed, including Sina, Sohu, 163, Tencent and Alibaba. That boom came to sa sudden halt when the internet bubble burst in 2000. “We were under great pressure when the Internet bubble burst. Things have only recovered since 2005,” Ma said. The IT sector was among the first batch of industries in China to experience zero-tariff treatment, meaning that the nation’s Internet sector had to face challenges from international peers.

QQ, with around 450 million users, provides services such as chatting, music, games and QQ currency-an indispensable currency in china’s virtual community. “ Chinese websites have survived the competition with foreign peers over the past ten years, but it will be the next ten years that decide Chinese Internet enterprises’ fate,” Ma said. Domestic enterprises have to compete with international companies on services, innovation and core technology, he said. One of Ma’s favorite films is March of the Penguins-a French documentary directed by Luc Jacquet. He said: “Penguin is a lovely animal to me. It is a combination of love, courage and adventurism.”
