Combinational simulations of free energy of polymer solution

It is conceptually proposed that the total entropy of polymer solution is contributed from two distinct parts: the positional and the oomformational. The former can be represented analytically, while the latter can be simulated with the random self-avoiding walk model on the simple cubic lattice for multichain systems. The obtained results indicated that both the conformational entropy and the mixing heat are consistent with the scaling laws wry well.

讨论了工艺过程中产生的界面态陷阱电荷Ｑ（ｉｔ）对高频ＭＯＳ－ＣＶ特性线的形变规律，提出了一种沿电压方向形变的数据处理方法，以此算出Ｑ（ｉｔ）密度在禁带中的分布，并对常规高频ＣＶ法的测量误差作了讨论和修正，由于数据的采集和处理可以由微机完成，使这种方法变得简便、准确并易于在工艺线上推广使用。     

Recognition of ring pairs in the data analysis of Cherenkov detectors

We present a new algorithm for the identification of ring pairs in Cherenkov detectors. The approach combines linear regression methods for the construction of an appropriate reference quantity, methods from statistics for the evaluation of hypotheses and Monte Carlo simulation runs for the tuning of threshold levels.

Interval parameter perturbation method for evaluating the bounds on natural frequencies of structures with interval parameters

For structural parameters with uncertainties, interval mathematics can, in the case where the probabilistic distribution density of uncertain variables is unavailable, deal with the influence of uncertainties in structural parameters on the response of structures. In order to evaluate the region containing natural frequencies of structures with interval parameters, the interval parameter perturbation method is presented in this paper. The advantage of the present method is its computational efficiency in evaluating the region containing natural frequencies. A numerical example is used to illustrate the efficiency of the method proposed. The project is supported by National Youth Natural Science Foundation of China and National Outstanding Youth Science Foundation of China.     

样条能量配点法分析高层框架结构

本文利用样条能量配点法来分析高层框架结构。先将框架模拟成等效性质的正交异性连续体,然后选取样条函数与连续函数的乘积来构成该连续体位移函数,最后用能量配点法来求解。
