求翻译：同时从模型估产的相对误差动态变化来看，随着时间的推移，即越临近小麦成熟期，估产误差越小，说明气象因素的累计作用对冬小麦估产具有重要的意义。是什么意思？

At the same time from the model estimation of the relative error of the dynamic of the changes, over time, that is, the closer wheat maturity, yield estimation error is smaller, the cumulative effect of meteorological factors on winter wheat yield estimation is of great significance.

Meanwhile looked from the model estimation relative error dynamic change that, along with the time passage, namely more approaches the wheat mature period, the estimation error is smaller, explained the climatic factor the accumulation function has the vital significance to the winter wheat estimati

At the same time relative error of the estimation of dynamic change of view from the model, with the passage of time, that is, the more approaches of wheat mature, smaller yield estimation error stating the cumulative effects of meteorological factors on winter wheat yield estimation is of great sig
