With such distortion profiles, the new theory can be used to investigate the stability behaviour of parallel shear flow, and thus suggests a new possible approach to instability.展开更多

In fact, confronting some of the elements of the theory with recent scientific discoveries, one cannot be anything but astounded by the magnificent capacity of the Athenian philosopher＇s investigations of the perceptible and metaphysical world, a true precursor of the times展开更多

This is something new in the annals of Chinese publishing history and also a mater of importance in the building of human fights theory in China. The launch of the journal is an indicator of China’s steady opening up and social progress and the healthy development of China’s human fights. For a considerably long period of time after the founding of New China, due to the influence of the ultra-展开更多

文摘This paper suggests a hydrodynamic stability theory of distorted laminar flow, and presents a kind of distortion profile of mean velocity in parallel shear flow. With such distortion profiles, the new theory can be used to investigate the stability behaviour of parallel shear flow, and thus suggests a new possible approach to instability.
