In this special issue of , seven peer-reviewed manuscripts appear on the topic of ultrasonic transducer design and operation in harsh environments: elevated temperature, high gamma and neutron fields, or the presence of chemically aggressive species. Motivations for these research and development projects are strongly focused on nuclear power plant inspections (particularly liquid-sodium cooled reactors), and nondestructive testing of high-temperature piping installations. It is anticipated that we may eventually see extensive use of permanently mounted robust transducers for in-service monitoring of petrochemical plants and power generations stations; quality control in manufacturing plants; and primary and secondary process monitoring in the fabrication of engineering materials.
在本刊的特刊中，有七篇经过同行评审的论文涉及超声换能器在恶劣环境下的设计和运行，包括高温、高伽马和中子场，以及化学腐蚀性物质的存在。这些研究和开发项目的动机主要集中在核电站检查（特别是液态钠冷却反应堆）和高温管道装置的无损检测上。我们预计最终可能会广泛使用永久性安装的坚固换能器，用于石化厂和发电站的在役监测、制造厂的质量控制以及工程材料制造过程中的主要和次要工艺监测。
