The theoretic model of framing camera\'s gain attenuation is analyzed.
分析了分幅相机增益衰减的理论模型,利用Mathematica软件模拟了增益随电脉冲传输时间指数衰减的曲线图。
An attenuation/gain function is drawn into the direct iteration search method that belongs to the multi variables extreme value research based on the optimization theory, so that it combines the quantitative method with the qualitative analysis by the experts and increases the explanatory ability and simulation level of the original model.
本文对确定型常参数预测方法中的自适应滤波技术加以改进，即在最优化理论中对多变量函数极值问题的直接迭代搜索性解法中引入衰减／增益函数，在建立预测模型时把对时间序列分析定量方法与专家对相关因素的定性分析有机地结合起来，提高了原自适应滤波模型的解释能力和拟合水平，特别适合于存量经济变量和某些流量经济变量在发生比较急剧变化阶段的预测。
