本文首先例举了句长限制一定、训练语料不同的情况下，GIZA++运行中的一些数据和图表，其中包括对运行时间、内存等资源消耗量的统计；然后统计了句长限制不同但训练语料相同的情况下，GIZA++的运行数据。通过使用最小二乘法对这些数据进行函数拟合，对GIZA++的计算性能进行初步的预测分析。该方法可以在过程运行前大致估计出所消耗的资源量，从而避免在运行中出现由于资源不足而导致程序崩溃的情况。

This article provides data and tables about time and memory for GIZA++ in the cases limiting the length of sentences as well as in the cases with a constant total number of sentences. The leastsquares method is also used to compute the approximating functions for them, by which some preliminary predicting analysis is further done for GIZA++.The method can predict the amount of resources to be consumed,and thus avoids the program collapse because of the shortage of resources in the running.
