- this paper studies nonlinear dynamic problems of tall building structures, first, constitutes linear dynamic equation and elasto-plastic dynamic equation of structure by using qr method, later, solves the dynamic equation by using spline unconditional stable algorithm, last, programs corresponding computer programs with c program language, and calculates some example and a tall building in constructing the courses and the results prove that qr method is not only simple in calculating and fast in constringency rate, but also precise, that qr method is a effective and economic new method
本文研究高层建筑结构弹塑性动力问题，先利用qr法建立了结构线性动力方程及弹塑性动力方程，然后利用样条无条件稳定算法求解了动力方程，最后利用c语言编写了相应的计算程序，计算了一些例题和分析了一个工程实例。qr法在理论上及方法上不用有限元法及流动法则，避免了这些传统方法在分析非线性问题时所带来巨大困难的缺陷。计算结果表明，这种方法不仅计算简便，而且精度高，收敛速度快，是一种经济有效的新方法。 - to overcome the drawback of the fdtd method in computing the pseudo low frequency electromagnetic problems, in the final, based on comprehensive study on the present adi-fdtd method, the thesis proposed an improved 2d adi-fdtd method . the numerical results show that the proposed method is more unconditional stable and computationally accurate than the conventional adi-fdtd ones
针对传统的fdtd法分析伪低频电磁场问题时的不足，通过系统研究交替方向隐格式时域有限差分法，本文提出了一种改进的二维交替方向隐格式时域有限差分法，并编制了相应的计算软件。 - in the models, the time dependent parabolic equations, deduced from the mild slope equations with currents or not, are used as the governing equations . based on the general conditions for open and fixed natural boundaries with an arbitrary reflection coefficient and phase shift, the boundary conditions for the present models are treated . the alternative direction implicit method is used to solve the governing equations and the numerical schemes are unconditional stable
在建立模型时，将原始的椭圆型缓坡方程的近似型式??依赖时间变化的抛物型方程，作为控制方程；从将开边界条件、不同反射特性的固壁边界条件相统一的表达式出发，对边界条件进行处理；用adi法数值求解控制方程，格式无条件稳定；节省了计算机内存和计算量。 - It's difficult to find unconditional stable in a sentence. 用unconditional stable造句挺难的
