This paper offered two pieces of practical arithmetic about encrypting of data by analyzing theory based on encrypting of data . two pieces of arithmetic are c encrypting of public key and many steps 通过分析基于数据的加密原理,本文给出了两个较实用的数据加密算法:公钥加密和多步加密算法。
With systematic analysis, this author is also to make a focal study on the vehicle routing in a supply chain and suggest a dynamic model together with a simple, practical arithmetic 运用系统分析的方法,对供应链环境下车辆路径问题进行重点研究,建立了动态模型,并给出一个简单可行的算法。
By the test, experimental datas proved : in this paper, by the practical arithmetic using image process technology, it can make accurate test on the precision of pcb hole drilling and hole diameter . this showed the method have credible stability and 通过现场初步试验,测试得到的数据证明:采用本论文选择的高分辨率光学摄像传感器和图像处理算法,对印制电路板钻孔精度和孔径的高精度检测,能够实现对电路板钻孔的自动检测和监控,具有较高的稳定性和实用性,基本满足pcb生产企业实际应用的需要。
