Digital oscilloscope template was built with virtual instrument technology so signal processing of wave shape display time frequency amplitude phase was implemented .

采用 虚拟仪表技术构造数字示波模板，以完成波形等显示，及 时间、频率、幅度、相位等信号 处理。

The complexity of model structure in Virtual Reality system causes too much polygons which damage the virtual scene roaming transform smoothly and frame processing can not be completed on time .

虚拟现实系统中模型结构复杂，模型多边形数目太多破坏了 虚拟漫游场景变换的平滑性，使模型的帧 处理不能 及时完成。

The virtual simulation machining can effectively detect and eliminate errors in the program to shorten the processing time reduce waste generation to avoid duplication of work and a substantial increase in work efficiency improve processing quality reduce production costs .

利用 虚拟仿真加工，可以有效的检测和消除程序中的错误，缩短 加工 时间，减少废品的产生，避免重复工作，大幅提高工作效率，改善加工质量，降低了生产成本。
