third, i present three methods to find vulnerabilities : source scan, fault injection and reverse engineering 其后具体阐述了如何检测软件中存在的安全漏洞,分为源代码扫描、软件错误注入和逆向工程三种办法。
there are several ways to achieve the multichannel measurement, and the single radiation source scanning method is the most feasible 实现多通道烟幕透过率测试有几种技术途径,单辐射源扫描式测试是其中最具有可行性的测试方法。
firstly, sp supposed to be generated by point curl source which is the border of dipole layer rather than the line dipole layer in section view, then, curl source scanning function is given, and image is retrieved by probability tomography approach 首先把剖面上偶极层的线分布产生的场看作是偶极层的边缘旋度源的点分布产生的场;然后给出旋度源的扫描函数,用概率成像方法对旋度源进行成像。
