摘要：1 判断结构是否适合用钢结构钢结构通常用于高层、大跨度、体型复杂、荷载或吊车起重量大、有较大振动、高温车间、密封性要求高、要求能活动或经常装拆的结构。直观的说：大厦、体育馆、歌剧院、大桥、电视塔、仓棚、工厂、住宅和临时建筑等。这是和钢结构自身的特点相一致的。

摘要：为了方便软件与应用系统的开发与调试,提出一种可复用的微处理器片上调试方法.通过设计通用的调试指令集和增加调试模块,并扩展处理器内核功能,实现了断点设置与取消、内核运行的流水级精确控制、内核资源访问、任意程序段运行中特殊事件的统计等片上调试功能.该方法已在自主研发的SuperV_EF01DSP上实现.在CMOS 90nm工艺下的综合结果表明,新增的片上调试功能不影响SuperV_EF01DSP的关键路径时序,而芯片总面积仅增加了3.87%.

摘要：To improve the accuracy of the vehicle crashworthiness simulation,it is necessary as well as important to integrate the valid forming effects of key *** has been agreed by many that one-step simulation results should be used only as a qualitative trend of the part but not as an engineering result for further structural analysis,especially for a relatively complex *** study shows that it is inaccurate to analyze the forming effects with one-step simulation based on the geometry of the final part through comparison with the incremental simulation and verification with the actual part,whether in thickness or in plastic ***,incremental simulation is very time consuming and infeasible in the early stage of vehicle design due to lacking of forming tools and process *** engineering approach is proposed to meet the requirement of accuracy as well as the time efficiency,where one-step simulation is conducted based on the geometry of the transformed part instead of the final *** geometry of the transformed part is generated by simple die design engineering and proves to offer much more accuracy than the one-step simulation based on the final part geometry.

摘要：三向SX-815E型自动生产线实训装备可以模拟一个与实际生产情况十分接近的控制过程，使学习者得到一个非常接近于实际的教学设备环境，从而缩短了理论教学与实际应用之间的距离。但是，在教学过程中，因各种原因，在调试过程中经常出现中断。程序中断后需要手动操作机械机构才能复位，既消耗了学生宝贵的实训时间，又在一定程度上加大了设备的损耗。本设计是探讨自动生产线在设计、调试过程中如何做到循序渐进，从手动、单步、单周期逐步进行调试，而又不需要使用复杂的IST功能指令，使得学生更容易掌握自动生产线在设计、调试的一般过程。
