【摘要】 利用日本微重力中心８００ｍ落井装置，完成了半浮区液桥振荡对流的微重力实验，对振荡对流的典型物理量诸如内部温度、流场、自由面边缘变化及表面波进行了综合测量。实验结果给出了振荡对流由地球重力环境向微重力环境的过渡，以及不同几何参数半浮区液桥的振荡特征，并首次获得了微重力环境下热毛细对流的表面波位形及边缘振荡特征．更多还原

【Abstract】 The inacrogravity experiments of oscillatory covection in liquid bridge of halffloating zone were carried out by using the 800 meter drop facility in the Japan Macrograv-ity Center,The coordinated measurements of typical physical quantities such as internaltemperature,flow field,edge variation of free surface boundary and free surface wave wererealized.The experimental results comprise the traiisition of oscillatory covection fromEarth’s gravity to microgravity environment and show that the oscillatory features are de-pending on the geometrical paranieters of the halfaoating zone。 Comfiguration of free surfacewaVe for the thermocapillary covection were alsoobtained for the first time.更多还原
