英文摘要： For a deeper research and exploration about virtual-oriented maintenance time measurement and dependability evaluation, this project would keep a foothold in the interdisciplinary area of virtual reality, maintenance engineering, human factors engineering and simulation science, and study what the inherent law between complex maintenance tasks and time. A measurement method of virtual maintenance time based on motion-time mechanism would be established by how complex maintenance tasks would be breakdown and compounded. Meanwhile, a compensation equation would be established to show what and how factors affect the accuracy of virtual maintenance time. And evaluation index system and method about dependability of virtual maintenance time would be proposed through a further analysis of internal and external factors. With solution to the problems of virtual-oriented maintenance time measurement, quantitative compensation and dependability, this project would improve the dependability of virtual maintenance verification technique and promote it in-depth development. What's more, this project could also provide a scientific idea to research what the otherness is between virtual reality and actual world.
