1．能正常计时。显示模式分为24小时制和12小时制。其中12小时制须显示上、下午。“时”、“分”、“秒”都要显示。 2．具有快速校准时、分、秒的功能。手动校准，用一个功能键选择校时、校分功能，用另一功能键调校对应时、分数值。 3．整点自动报时。在离整点10s时，便自动发出鸣叫声，步长1s，每隔1s鸣叫一次，前四响是低音，最后一响为高音，最后一响结束为整点。 -1. To resume normal time. Display mode is divided into 24-hour and 12-hour clock. Including 12-hour clock to be displayed on the afternoon. "Time", "sub", "seconds" must be displayed. 2. Fast calibration, minutes and seconds functions. Manual calibration, using a function button to select the school, the school hours functions, corresponding with another function key set, the score values. 3. The whole point of automatic timekeeping. The whole point away from the 10s, they automatically send calls, step 1s, at intervals of 1s tweet once, the first four bass sound is the last one for the treble ring, ring the end of the last one for the whole point.

给出了沉浸式虚拟维修仿真系统的框架，从样机建模和交互技术两个方面对其关键技术进行了研究．提出 了虚拟维修样机的概念，通过定义样机部件的约束运动和交互特征来实现其所要求功能，而交互技术则主要集中在 抓取和防穿越处理上．建立了基于Jack系统的沉浸式虚拟维修仿真原型系统，并以某机构的拆装为例对其进行了初 步的应用验证-Give the Immersive Virtual Maintenance Simulation System framework, from prototype modeling and interactive technology for its two key technology areas were studied. Put forward the concept of a virtual prototype of repair, by the definition of prototype components bound to exercise and interactive features of implementation of its functional requirements, and the interactive technology was mainly concentrated in the crawl up and deal with anti-crossing. Jack set up a system based on Immersive Virtual Maintenance Simulation prototype system and the dismantling of an institution as an example of its application for a preliminary verification
