奥运官网7月23日讯 今天下午，北京奥组委开闭幕式工作部常务副部长、北京奥运会开闭幕式运营中心主任王宁介绍了8月8日晚烟火燃放的情况。配合开幕式文艺表演和仪式程序的进程，在国家体育场顶部、奥林匹克中心区、奥林匹克森林公园、城区中轴线和居庸关长城等处燃放眩目多彩、造型各异的焰火，营造欢庆、热烈的奥运气氛。总长度大约20分钟。

从公布的信息可知，开幕式焰火燃放阵地分布在国家体育场、奥林匹克中心区、龙形水系、奥林匹克森林公园、城市中心等地。奥运会开幕当晚，从永定门经过天安门到达鸟巢的历史中轴线上，共设立29个焰火阵地燃放特效造型焰火，以表现第29届奥运会来到中国，来到北京，来到鸟巢。国旗升起后，采用红、黄两色牡丹礼花弹，沿着龙形水系上的22个燃放阵地迅跑，展现了跨度长达3.5公里的巨龙奔腾。在展示从世界各地征集来的数千张笑脸照片时，天空同时也打出2008个笑脸的焰火。圣火点燃后，鸟巢空中和居庸关长城上会出现同样的焰火造型，表现古今同步、跨越时空的对话。

据王宁介绍，开幕式焰火燃放呈现出这样的特点，首先是与文艺表演和仪式程序紧密结合。除在开幕式结尾部分集中燃放焰火，形成高潮之外，焰火燃放将贯穿节目始终。我们将根据节目内容和进程，燃放具有特殊造型的烟花，使之成为开幕式不可分割的重要组成部分。

第二个特点是突出了奥林匹克元素。焰火燃放的有些造型，将试图融入奥林匹克形象和寓意，凸显奥林匹克理念。比如，用特殊的焰火造型体现奥林匹克走进中国、走进北京、走进鸟巢的寓意，表达中国人民对“百年奥运”的殷切期盼；我们还将首次用烟花打出奥运五环造型等一些特殊效果。

同时，烟火燃放还具备高科技的特点。焰火燃放将采用空气发射技术、膛压发射技术，并采用数码点火控制系统进行控制。这些技术都是在焰火燃放中第一次使用。

为了体现绿色奥运的理念，焰火燃放将使用部分微烟火药和先进的发射技术，减少烟花燃烧后的烟尘、残渣和垃圾，减轻对环境的污染和负面影响。

焰火燃放一方面会为场内的观众服务，渲染现场气氛；同时也考虑到周边地区的市民，让他们也可以一同欣赏到烟花绽放的美景，整个奥林匹克中心区将成为开幕式现场的延伸，构成城市景观的一部分。

王宁透露,开幕式焰火燃放除了使用喷泉、花束、罗马烛光、盆花、礼花弹等传统烟花品种外，还将使用芯片礼花弹、特效造型礼花弹、微烟焰火等新型烟花品种。

王宁表示，由于焰火燃放范围广，环节多、实施难度大、安全要求高。为了保证焰火燃放的安全、顺畅，已经组织有关部门和专家制订了焰火产品及设备的质量、安全、技术、检验及验收标准文件，对烟花生产、检验、运输、储存、燃放的全过程进行监管，确保了产品质量和产品安全。同时，经过充分的论证，制订完成了周密的焰火燃放实施方案、组织运行方案，建立了严密的指挥通讯系统，采取措施确保燃放现场及周边人员、设施和建筑物的安全。

王宁说，7月16日在进行开幕式首次带妆彩排时，按照8月8日的焰火燃放规模，在鸟巢本体等核心区域进行了同比例的焰火“试燃放”。当天晚上，许多市民有幸观赏了精彩的焰火表演，许多网友还在网络上发布了大量的焰火表演的视频和图片。总体上讲，焰火表演达到了预期的艺术效果，组织运行和安全保障都得到了测试。这次焰火燃放对国家体育场钢结构、膜结构均无任何影响和损坏，也没有对现场观众产生影响。

(BEIJING, July 23) -- Fireworks will be set off during the opening ceremony of the Olympic Games on August 8 to create a joyous and festive atmosphere, an official said on Wednesday.

Wang Ning, deputy director of the Opening & Closing Ceremonies Department of BOCOG, said fireworks of different shapes will be displayed above the main stadium of the Games, Olympic Forest Park and the Juyongguan section of the Great Wall.

"For the first time, the shape of the Olympic Rings will be formed in the sky," said Wang, adding that Olympic symbols and elements will be a part of fireworks' designs with an aim to promote Olympic ideals.

Firing skills will feature compressive air launches, chamber pressure launches and computerized ignition technologies, employed for the first time in the display of fireworks, he told the media attending a press conference in Beijing.

To reflect the "Green Olympics" concept, some of the fireworks will use less smoking powder to minimize smoke and dust pollution, Wang said.

The designers intend to highlight the fireworks' effect both on the ceremony's stadium and larger areas around the facility so that the Olympic central zone will be an extension of the ceremony owing to the splendid fireworks.

Cai Guoqiang, a member of the core creative team in charge of visual & special effects of the opening and closing ceremonies for the Beijing Olympics and Paralympics, updated the press on the implementation of a comprehensive design and production project.

He said he joined the team in 2005 and it took him 2 to 3 years to do preparatory work. "Gunpowder is one of the inventions of China, but the fireworks this time are not only for the sake of pumping up the atmosphere, but also have a goal to achieve - playing the role of storyteller," he said.

Cai gave an example: Along the dragon-shaped landscape water system of the Olympic Green, the fireworks will be fired up into yellow and red peonies. The computer ignition system will control the fireworks, and within seconds, the fireworks will span 2 to 3 kilometers following the flag raising process.

During the climax of the art performances, the firing squad will display thousands of pictures of smiling faces collected from around the world, according to Cai's design. At that moment, fireworks will mimic 2008 smiling faces in the sky, said Cai.
