脉冲数调制 - As analyzing the electromagnetic scattering characteristics of two - dimensional electrically large conducting objects , the object is divided into some small regions by using spatial decomposition technique ( sdt ) , but still consider the coupling effect among all the regions , the surface current and rcs of the object can be computed with progressive iterative numerical method ( pnm ) . then the wide - band electromagnetic scattering characteristics of two - dimensional electrically large conducting objects are analyzed with the asymptotic waveform evaluation ( awe ) technique
文中应用空间分解技术( sdt )将二维电大导体目标在空间中分解为若干子区域，考虑子区域间的耦合，采用累进迭代方法( pnm )快速计算表面电流和雷达散射截面，然后与渐近波形估计技术( awe )结合分析了二维电大导体目标的宽带电磁散射特性。 - Then an efficient and more accurate nonlinear finite element procedure based on the plastic node method ( pnm ) by combining elastic large displacement analysis theories with a plastic hinge model is presented to analyze the ultimate strength , directly accounting for the geometrical and material non - linearity and the influence of initial deformation and residual stress
然后采用塑性节点法，考虑结构的几何非线性和材料的非线性双重以及各缺陷因素影响，分析了不对称船体结构的极限强度。通过与实验值的比较，说明简化方法与塑性节点法都能较准确预报极限强度。
