Based on the traditional plastic limit analysis , an improved rigid - nonlinear hardening approximate model is established 摘要应用传统的极限分析理论,提出一种改进的刚性非线性强化近似模型。
However , the analyses of suspension bridge structures are still preferred by finite displacement analysis based on 2d ( two - dimensional ) or spatial skeleton approximate models 但大跨度悬索桥的分析至今还局限于用平面或空间骨架近似模型。
Using the approximate model of main steam pressure and linear quadratic optimal control theory , the lq sub - optimal control strategy is brought forward 基于主蒸汽压力降阶近似模型和二次型最优控制原理,文中还给出了主蒸汽压力的lq次优调节策略。
The second section : the process of induce heating is a complex process . after analysis the heating mechanism , this thesis build up an approximate model for the system 二、感应加热的过程是一个很复杂的工业过程,它涉及电、磁及热等多种物理过程。
Additionally , the comparison between these two methods is made . due to the approximate model - independence of anc method , the final results are adopt the values given by the anc method 由于anc方法的模型近似无关性,采用该方法给出的值作为最终结果: 13c基态、第一和第三激发态anc系数分别为1
We use a scaling matrix which make the algorithm generate sequences of point in trust region and the interior of the feasible set . because of the boundedness of the trust region , trust region algorithm can use non - convex approximate models 构造合理的仿射变换矩阵,在投影空间构造信赖域子问题,产生迭代方向,使迭代点既保持在信赖域内,又是严格可行域的内点。
A study is made of the theory of linear fractal interpolation and a model called fractal interpolation approximate model is presented from the self - similarity of share price signals . also , a comparison is made of the interpolation method and times 研究了线性分形插值理论,结合股价信号的自相似性,提出了股价序列分形插值逼近模型,并作了插值方法和插值次数的比较。
For the characteristic of the river course and the conditions of water - sand are different in adjacent year . it follows the thinking that respectively build approximate model by the data of water - sand in different years , then finds out the forecasting model by recurring the approximate parameter array of each year 由于连续年份下河道特性、水沙条件的差异,本文采用各年水沙资料分别建立拟合模型,各年拟合参数按时间序列递推给出预报模型的研究思路。
