城市天然气技及其发展.doc

摘 要 科学技术的国际接轨不同简单的引进国外先进设备，而是应在市场经济条件下，结合本国情况，通过消化吸收和采用先进的科学技术，使整个燃气系统取得与先进国家相类似的经济效益，因此，科学接轨应该是一个广义的概念，它包括决策、经济、设备和管理等各个方面。各国城市燃气发展的模式不同，欧、美和日本就有很大的差异，因此，科技接轨必须博采众长，但提高效益的目标是一致的。科技接轨是否成功，最终应以取得的效益来评价。科技接轨的当前任务，首先应反映在规范、规程和标准的国际接轨上。 随着城市燃气的发展，用气户的增加，安全问题也日益突出，事故屡有发生。安全问题有主动的安全措施和被动的安全措施两类。主动的立足于预防，被动的立足于事故发生后，应将损失控制在最小范围之内。两者均应考虑到，但重点应放在主动的措施方面。 关键词：燃气；发展；现状 ABSTRACT International Rail pulling of science and technology of the simple introduction of foreign advanced equipment, but should be under the condition of market economy, combined withtheir own situation, through digestion and absorption of advanced technology, make the wholegas system similar to the advanced countries economicbenefit, therefore,scientific standards should be a broad concept, which includes each decision, economy, equipment andmanagement etc.. City gas development pattern of different countries, Europe, America and Japan have verybig difference, therefore, technology standards must learn widely from othersstrong points, but to improve the efficiency of the goal is the same. The success of technology standards, and ultimately should benefit evaluation. The current task of science and technology standards, first of all should reflect the international standards in thespecifications, codes and standards. With the development of city gas, with the increase of gas users, security issues are also increasingly prominent, accidents happen repeatedly. Security problems of active safety measures and passive safety measures too. The initiative is based on prevention, passivebased on after the accident, the loss of control at a minimum range. Both of them should be taken into account, but the emphasis should be put on the active measures.
