As a case in this study, there is a non–representative PK duality model which adopts the least squares method or even the Monte Carlo method to estimate their parameters. Using yield frequency analysis to recommend fertilization, only a group of P and K coenobium, the sixth treatment, meets the conditions of goal yield.

对Monte Carlo法也不能得到典型式的晚稻磷钾非典型肥效模型，用产量频率分析法计算推荐施肥量，表明只有一组磷钾肥用量组合入选，导致磷肥推荐用量偏高而钾肥偏低。

It stands that the coenobium number is not enough as a basis for fertilization recommendation, and results in the P recommending application rate on the high side and K on the low side. Under the same goal yield, the Monte Carlo method may obtain the average P and K recommending application amounts which are within the P and K optimum application rates based on NP, NK and NPK multivariate representative models in the same experiment sites.

在相同目标产量下，改用Monte Carlo法，平均推荐用量介于相同试验地所建立的氮磷、氮钾和氮磷钾典型肥效模型的推荐用量之间，结果明显优于产量频率分析法。

When the concentration of MAH is higher than that of St, some MAH monomer reacts with St to form SMA, others can directly grafts onto PP macroradicals. When the amount of St added is higher than that of MAH, part of St monomer may preferentially react with PP macroradicals to form more stable styryl macroradicals, while others copolymerize with MAH, yielding SMA. MFR of the grafted PP is lower in this case. It is considered that MFR of the grafted PP is decided by concentration of free monomers, or, number of grafting reactive species. FTIR analysis confirmed the above mechanism.

当MAH单体用量多于St单体时，一部分MAH单体与St反应生成SMA，另一部分可直接与PP大分子自由基进行接枝反应；当St单体用量多于MAH单体时，除与MAH反应生成SMA之外的St单体可先与PP大分子自由基反应，并起到稳定PP自由基的作用，这时接枝物的MFR较小，亦即接枝物的MFR与体系中可进行接枝反应的活性种数目有关。
