我国发电总量的估测与比较分析卢建昌,牛东晓摘 要:电力工业是国民经济的基础性工业,发电量是电力工业发展水平的一个重要指标,对发电量的准确预测有利于电力工业的可持续健康发展.分别用ARIMA模型和传递函数模型对我国未来5年的发电总量进行估测,并分别对两种模型建模的过程和结果进行比较和分析.两种模型在发电量的预测中各有利弊,根据ACF和PACF,ARIMA模型较好;根据Residual和Fitted,传递函数模型较好.关键词:发电量;ARIMA模型;传递函数模型;......
than 10 nm. The sample has superparamagnetic(SPM) properties above the blocking temperature of ~16 K. The temperature dependence of magnetization was well fitted by Bloch T3/2 law considering the dipolar interaction of the particles. The field dependence of magnetization was fitted with revised Langevin equation.The magnetization of the weak ferromagnetic(WF) canted spins contributes to the linear......
Institute of Technology2. School of Materials Science and Engineering, Shanghai University摘 要:A fitted function method to describe the strain fields during..., and the deviations between experiment and simulation are less than 24%. Therefore, the fitted function method can be applied to optimize the stretching process for large forgings. The optimal value of feed......
(TG-DSC). Moreover, 2,4,6-trichlorophenol(TCP) was removed effectively(94.7% of removal percentage in 9h) under the optimized experimental conditions. The adsorption kinetics data fitted... fitted the Freundlieh adsorption isotherm with good values of the correlation coefficient. A mechanism of the adsorption process is proposed according to the intraparticle diffusion model, which......
was analyzed. Quadratic intensity dependence was only observed at weak excitation intensity. With increasing the excitation intensity, saturation was turned out. The experimental results were fitted......
值的对数偏差量数据不服从正态分布,而基于其他模型蠕变方程的偏差量数据服从正态分布且不存在异常值,这说明拟合数据与实测数据之间不会出现明显的偏差. 图5 不同模型下蠕变速率拟合值与实测值的对数偏差量在正态概率图上的分布 Fig. 5 Logarithmic difference distribution of actual measurements and fitted...变本构方程分别如下: 图6 不同模型下蠕变方程拟合数据与实测数据的对比 Fig. 6 Comparison of actual measurements and fitted creep data by different models 图7 不同模型下蠕变方程预测数据的有效性检验 Fig. 7 Effectiveness of fitted......
