Translational bubble dynamics is much less studied than the dynamics of radial bubble oscillation, while in many scientific and engineering applications the control of space location of cavitation bubbles is of great practical importance. This paper aims at the theoretical study of various aspects of the translational motion of a spherical gas bubble in a high-frequency standing wave. In particular, it is shown that the translational instability that gives rise to the reciprocal translation of a spherical bubble between the pressure antinode and the pressure node is caused by the hysteresis in the main resonance of the bubble. Different types of translational trajectories that can occur in a standing wave are illustrated by numerical simulations. A general classification of the observed translational trajectories is proposed.

Applied Acoustics

自 1968 年成立以来，APPLIED ACOUSTICS 一直在发表高质量的研究论文，为从事最广泛意义上的声学应用的工程师和科学家提供最先进的研究成果报道。APPLIED ACOUSTICS 不仅着眼于最近的发展对声学的理解，以及利用这种理解的方式。该杂志旨在鼓励通过出版交流实践经验，并以此创建可用于解决相关问题的技术信息基金。特别鼓励以图形或表格形式呈现信息。如果数学发展报告是论文的必要部分，那么重要的是要确保它只是作为问题的实际解决方案的一个组成部分，并有数据支持。 APPLIED ACOUSTICS 鼓励通过以下方式交流实践经验： • 完整的论文 • 简短的技术说明 • 评论文章；从而提供了丰富的技术信息，可用于解决相关问题。欢迎提交涉及从医学和无损检测到环境和建筑物的声学应用的所有领域的手稿。

Since its establishment in 1968, Applied Acoustics has been publishing high-quality research papers, providing cutting-edge research findings for engineers and scientists engaged in the broadest sense of acoustic applications. The journal not only focuses on the latest developments in understanding acoustics but also explores ways to utilize this understanding. It aims to encourage the exchange of practical experiences through publication, thereby creating a technical information foundation that can be used to address relevant issues. Information is particularly encouraged to be presented in graphical or tabular form. If mathematical developments are a necessary part of the paper, it is important to ensure that they are merely a component of the practical solution to the problem, supported by data. Applied Acoustics encourages the exchange of practical experiences through the following means: • Full papers • Short technical notes • Review articles; thus providing a wealth of technical information that can be used to solve relevant problems. Manuscripts covering all areas of acoustic applications, from medicine and non-destructive testing to environmental and architectural acoustics, are welcome.
