验证了基因外显子的三周期特性，提出了一种优化确定阈值的方法，分别用固定窗口滑动，及滑动序列来对基因进行识别-Verified exon three-cycle characteristics, proposed an optimization to determine threshold and using fixed window sliding and sliding sequence to identify genes

以250bp为窗口沿着染色体滑动，计算每个窗口的GC含量。-250bp for the window to slide along the chromosome, calculate GC content of each window.
