对于线粘弹性裂纹体，当外应力是常数时，各位移分量均是时间相依的，且是材料流变常数的函数。
For linear viscoelastic cracked bodies, when the applied stresses are constant, the displacement components are time dependent and are functions of rheological constants of materials.
文章针对这一问题，在数据为混合相依的条件下，给出一般函数条件数学期望的估计，并讨论了它的收敛速度。
In this paper, the author gives a solution for this problem and discusses the convergent rate of nonparametric kernel estimate under mixing dependent data.
对相依时间序列数据，在一定的条件下已有人证明了局部多项式加权回归系数估计服从渐近正态分布，其中核函数是有界的。
Fan J and Gijbels I gave the asymptotic normality of local polynomial regression estimation in dependent time series, where the weighted function is bounded.
