实际问题中常常得到的是一个时间间隔为t的单变量的时间序列，它是许多物理因子相互作用的综合反映，蕴藏着参与运动的全部变量的痕迹，传统的时序分析是直接从这个序列去形式地分析它的时间演变，一维分析必然丧失许多有用信息，相空间重构方法的特点是把一维标量数据构造成高维矢量，支起状态的几何空间，在相空间中展示系统全部动力信息。本文正是根据相空间重构的特点，对响应时间序列进行分析，利用符号动力学、重构相空间等方法，提出一种有理论依据的系统数学模型关联度分析方法，从而达到修正计算数学模型，使其更符合实际系统状态的目的。 - abstract : based on the fundamental principle of hypothesis strain equivalence, itwas investigated a physical concept of high strength concrete at minus temperature ( hscmt ) freezing damage parameter, the elastic modulus of frost concrete with anti freeziug admixture and without antifreezing admixture built and it was analyzed their variate process and the condition adaptated . it is purpose to judge hscmt frost failure process

- based on the theory of stochastic finite element, the structural parameters of frame-shear structure including stiffness and mass and damping are simulated to be stochastic variables . by solving recurrence equation of stochastic finite element, the duration curve of mean value and standard deviation of seismic response can be obtained for every floor of frame-shear structure . an analysis is thus given to the effects of independent variation and simultaneous variation of structural parameters on the seismic dynamic response of frame-shear structure . as shown by the results, with regard to frame-shear structure, the effect of variation of strucural parameters on the change of mean value are chiefly the increase of standard deviation of response . variation of stiffness will cause the response of frame-shear structure to variate greatly; variation of mass shows less effect; and variation of damping shows insignificant effect . the effects of simultaneous variation of various structral parametres on seismic response are only slightly greater than the effect of stiffness variation alone
以随机有限元理论为基础，将框剪结构的刚度、质量、阻尼等结构参数为随机变量.通过求解随机有限元的递推方程，得到框剪结构各层的地震动力响应均值和标准差历时曲线.分析结构参数单独变异，以及同时变异对框剪结构地震响应的影响.研究结果表明,对框剪结构而言，结构参数的变异对响应的均值变化影响都不大，主要是增大响应的标准差.刚度的变异性将引起框剪结构的响应发生大幅度变异，质量的变异性影响稍小，阻尼的变异性影响不显著.结构各参数的同时变异，对框剪结构地震响应的影响，仅比刚度单独变异的影响稍大 - by introducing the single factor experiment model, considering the single tank's technique level and the firing score as variance factor and response variate, we analyze experiment data, calculate if the change of the factor influence the firing score, then we can conclude if there is some defference in technique level between each tank
