长期以来,由于美国和世界各国在日常工作中对能源需求的不断增涨,制造发电设备的厂家都希望能生产出效率更高的火力发电和原子能发电设备来满足这种要求。当美国政府尚未制订出能源政策之前,许多工程技术人员已在努力研究强度高、韧性大的合金材料,更有效的制造工艺,以及对零件和整体等更完善的检验方法。对这工作进行得最积极的要算燃烧工程公司(以下简称CE)和拨柏葛·威尔科克斯公司(以下简称B & W) For a long time, as the United States and other countries in the world constantly increase their demand for energy, manufacturers of power generation equipment all hope to produce more efficient thermal power and nuclear power generation equipment to meet this demand. Until the U.S. government has enacted an energy policy, many engineers and technicians are already working hard on high-strength, tough alloy materials, more efficient manufacturing processes, and more sophisticated inspection of parts and whole parts. The most aggressive work to be done is to count on Burning Engineering (hereafter referred to as CE) and Plato Wilcox (hereinafter referred to as B & W)
