摘要	The microgravity research, as a branch of the advanced sciences and a spe- cialized field of high technology, has been made in China since the late 1980's. The research group investigating microgravity fluid physics consisted of our col- leagues and the authors in the Institute of Mechanics of the Chinese Academy of Sciences (CAS), and we pay special attention to the floating zone convection as our first research priority. Now, the research group has expanded and is a part of the National Microgravity Laboratory of the CAS, and the research fields have been extended to include more subjects related to microgravity science. Howev- er, the floating zone convection is still an important topic that greatly holds our research interests. 目录 1. models of floating zone convection 1.1 floating-zone crystal growth 1.2 physical model 1.3 hydrodynamic model 1.4 mathematical model references 2. basic features of floating zone convection 2.1 equations and boundary conditions 2.2 simple solutions of fz convection 2.3 solution for two-layers flow 2.4 numerical simulation 2.5 onset of oscillation references 3. experimental method of fz convection 3.1 ground-based simulation experiments for pr≥1 3.2 temperature and velocity oscillations 3.3 optical diagnostics of free surface oscillation 3.4 critical parameters 3.5 microgravity experiments 3.6 ground-based simulation experiment for pr《1 .references 4. mechanism on the onset of oscillatory convection 4.1 order of magnitude analysis 4.2 mechanism of hydrothermal instability 4.3 linear stability analysis 4.4 energy instability of thermocapillary convection 4.5 unsteady numerical simulation of 2d and 3d 4.6 two bifurcation transitions in the case of small pr number fluid 4.7 two bifurcation transitions in the case of large pr number fluid 4.8 transition to turbulence references 5. liquid bridge volume as a critical geometrical parameter 5.1 critical geometrical parameters 5.2 ground-based and mierogravity experiments 5.3 instability analyses of a large prandtl number (pr≥1)fluid 5.4 instability analyses of a small prandtl number (pr《1)fluid 5.5 numerical simulation on two bifurcation process references 6. theoretical model of crystal growth by the floating zone method 6.1 concentration distribution in a pure diffusion process 6.2 solutal capillary convection and diffusion 6.3 coupling with phase change convection 6.4 engineering model of floating zone technique references 7. influence of applied magnetic field on the fz convection 7.1 striation due to the time-dependent convection 7.2 applied steady magnetic field and rotational magnetic field 7.3 magnetic field design for floating half zone 7.4 influence of magnetic field on segregation references 8. influence of residual acceleration and g-jitter 8.1 residual acceleration in microgravity experiments 8.2 order of magnitude analyses (oma) 8.3 rayleigh instability due to residual acceleration 8.4 ground-based experiment affected by a vibration field 8.5 numerical simulation of a low frequency g-jitter 8.6 numerical simulation of a high frequency g-jitter references
