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。
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。
