对于一个科学家来说，没有什么比意识到他/她的专业领域正在发展，昨天的知识状态在今天已经过时更令人兴奋的了。杰出的哲学家恩斯特·马赫在1878年首次报道了冲击波反射现象，距今已有125年。对这一迷人现象的研究随后被放弃了大约60年，直到约翰·冯·诺依曼教授和布莱克利克尼教授在20世纪40年代初开始研究。在他们的监督下，进行了15年与伪定常流中冲击波反射各个方面相关的深入研究。正是在这一时期，人们发现了四种基本的激波反射构型：规则反射、单马赫反射、过渡马赫反射和双马赫反射。从50年代中期到60年代中期的10年时间里，世界各国（如澳大利亚、日本、加拿大、美国、苏联等）对激波反射现象的研究一直处于低潮。直到苏联的Tatyana Bazhenova教授、加拿大的Irvine Israel Glass教授和澳大利亚的Roy亨德森教授重新开始了对这一现象和相关现象的研究。在他们的科学领导下，报告了许多与这一现象有关的调查结果。在20世纪70年代中期，由多伦多大学航空航天研究所的Irvine Israel Glass教授领导的研究小组可能是最有成效的。1978年，也就是马赫第一次报告他关于反射现象的发现的整整100年之后，我发表了我的博士论文。论文中，第一次，分析过渡标准之间的各种冲击波反射配置建立。我的博士学位的发表，是因为我至今还不知道的原因。这些发现引发了对反射表面的各种几何形状和性质以及各种气体中的冲击波反射现象的深入实验和分析研究。实验研究的中心从加拿大转移到了日本，特别是由高山和义教授领导的冲击波研究中心。在他的监督下，流动可视化技术达到了
Nothing is more exciting to a scientist than realizing that his/her areas of expertise are developing and that the state-of-the-knowledge yesterday is outdated today.The distinguished philosopher Ernst Mach first reported the phenomenon of shock wave reflection over 125 years ago in 1878. The study of this fascinating phenomenon was then abandoned for a period of about 60 years until Professors John von Neumann and Bleakney initiated its investigation in the early 1940s. Under their supervision, 15 years of intensive research related to various aspects of the reflection of shock waves in pseudosteady flows were carried out. It was during this period that the four basic shock wave reflection configurations, regular, single-Mach, transitional-Mach and double-Mach reflections, were discovered. Then, for a period of about 10 years from the mid-1950s until the mid-1960s, the investigation of the reflection phenomenon of shock waves was kept on a low flame all over the world (eg Australia, Japan, Canada, USA, USSR, etc.) until Professor Tatyana Bazhenova from the USSR, Professor Irvine Israel Glass from Canada, and Professor Roy Henderson from Australia re-initiated the study of this and related phenomena. Under their scientific leadership, numerous findings related to this phenomenon were reported. Probably the most productive research group in the mid-1970s was that led by Professor Irvine Israel Glass in the Institute of Aerospace Studies of the University of Toronto. In 1978, exactly 100 years after Ernst Mach first reported his discoveries on the reflection phenomenon; I published my Ph. D. thesis in which, for the first time, analytical transition criteria between the various shock wave reflection configurations were established. For reasons which for me are yet unknown, the publication of my Ph. D. findings triggered intensive experimental and analytical studies of the shock wave reflection phenomenon over a variety of geometries and properties of the reflecting surface and in a variety of gases. The center of the experimental investigation was shifted from Canada to Japan, in general, and to the Shock Wave Research Center that was led by Professor Kazuyoshi Takayama, in particular. Under his supervision flow visualization techniques reached such
