摘要：

The operation of a real-time task under Microsoft's Windows 98 Operating System was investigated. The uniformity of the frame rate achieved in an animation program was measured to assess its suitability a visual stimulus in a physiology experiment. Much better performance is obtained when timing of the animation is controlled by the thread scheduler of the operating system, rather than using the hardware timing which is more traditionally used.
