For the thrashing due to true sharing of data, we thoroughly study the relationship between array element accesses and loop indices of a nested loop, present a complete set of ideas, theories, and methods with which the staggering relation and the compacting relation between the threads of the nested loop (either with a single linear function or with multiple linear functions) can be determined at compile-time, and accordingly the nested loop (either perfectly nested or imperfectly nested) can be restructured to avoid the thrashing problem.

使用这套理论和方法，我们在编译时就可以确定出嵌套循环（含单线性函数或多线性函数，紧嵌套或非紧嵌套）各线索间的错位关系，一致错位关系和压缩关系，根据这种关系对嵌套循环进行重构可以使真共享抖动问题得到很好的解决。

Secondly, according to the spectral correlation theory of second order cyclostationary processes, maximumlikelihood filters are used to estimate the cyclic spectra. By estimating the crossspectra of the two frequency shifted versions of cyclostationary signal, the cyclic spectra can be obtained. The analysis effective bandwidth of maximumlikelihood filters is studied in details. In case of cross-spectra estimation, the analysis effective bandwidth of maximum-likelihood filters is not correct. A new method to calculate the analysis effective bandwidth is presented.

第二，根据二阶周期平稳随机信号的谱相关理论，提出了循环谱密度估计的最大似然滤波器法，即采用最大似然滤波器估计出周期平稳信号的两个频移分量之间的互谱密度，从而得到了循环谱密度的估计；对最大似然滤波器的有效分析带宽做了详细的分析，指出了在互谱密度估计时以往的有效分析带宽不正确，并提出了互谱密度估计时的有效分析带宽的新的计算方法。
