As for the data files of type 'w', that we can compact with LZ78 in some rapidly optimizing speed, the optimum selection of 'h' could take the highest compression ratio.

而对于采用LZ78压缩优化速度较快的W类数据文件，H参数的最佳选择可以得到最高的压缩比。

Then through experiments of comparing the improved algorithm with LZ77 and LZ78 in compression ratio and compression time, we conclude that the improved algorithm performs much better overall.

进而通过实验，将改进后的算法在压缩率和压缩时间上与LZ77和LZ78算法相比较，得出改进后算法在整体上的性能优于LZ77和LZ78。
