研制了一种能在高温下长时间产生100万g以上的超重力加速场的装置，用于凝聚态原子的沉降。该系统由油悬浮轴承高温空气涡轮机电机和钛合金试件转子组成。实验结果表明，在内径为40 mm的转子上，最大转速可达220 000 rpm，试样可在300 ℃以上连续加热数天。在温度> 200摄氏度时，最大加速度场大于1.1 × 10（6）g。该装置可用于高温固体和液体中的强加速度场（兆重力场）科学。(C)1996年美国物理研究所。
An ultracentrifuge apparatus to generate a strong acceleration field of up to or higher than 1 000 000 (1 x 10(6)) g at high temperature for long times has been developed for sedimentation of atoms in condensed matter. The system consists of a high-temperature air turbine motor with oil-floating bearing and a specimen rotor made of a titanium ahoy. It was confirmed that the ultracentrifuge experiment could be performed for a maximum rotating speed greater than 220 000 rpm with a rotor inner diameter of 40 mm. The specimen could be heated to over 300 degrees C far durations of several days. The maximum acceleration field achieved was higher than 1.1 x 10(6) g for temperatures > 200 degrees C. This apparatus can be used for strong acceleration field (mega-gravity field) science in solids and liquids at high temperature. (C) 1996 American Institute of Physics.
