As umbirfpa is a new type of infrared detecting device , its work principle is complex and its performance is affected by many factors . in the initial stage of developing , the design experiment and theoretical understanding are little interiorly . furthermore , the problems such as sensitivity reduced , dynamic range shortened , nonuniformity increased come forth if umbirfpa is not designed properly Umbirfpa是一种新型的红外探测器件,微测辐射热计的工作原理复杂,其性能受到很多因素的影响,目前国内尚处于发展初期,缺少实际的设计经验和理论认识,同时umbirfpa又是在集成电路工艺线上生产的,投资大、周期长,如果设计不当,不仅可能导致灵敏< wp = 13 >度降低、动态范围缩小、噪声增大、非均匀性增大等问题,更可能的是根本就不能用于成像,从而造成很大损失。
In order to get through the undergraduate teaching quality evaluation organized by the ministry of education , we have a research on the cognizance of comprehensive designing experiments , and at the same time , we also briefly discusses some problems which should be paid more attention to in the process of comprehensive designing experiments 摘要为顺利通过教育部普通高等学校本科教学工作水平评估,对如何开展综合性设计性实验认定进行了探讨,并对开展综合性设计性实验中注意的几个问题进行了简要阐述。
In order to realize the function of this system , a virtual parts library was established with solidworks and three - dimensional parameterized modeling was realized at the same time based on the practical part prototypes , which have been used in mechanism kinematics scheme design experiments in the physical laboratory 首先,以机构运动方案设计实验用到的实物零件为原型,用solidworks软件对各类零件进行了三维参数化造型,建立了一个虚拟零件库。然后,根据实现系统功能的需要编制了相应的程序模块。
Water hydraulic pressure servo loading system can be used to execute static presses test , the tired test , the sum settle strength test , the resilience split test , static structure strength test , the structure pieces design experiments among others . it has a very extensive application in the aerospace field 水压伺服加载系统可用来对负载结构件进行静力抗压测试、疲劳测试、额定强度、断裂韧度、结构静强度、操作容限设计等试验,在航空航天领域有着十分广泛的应用。
