1) profile bar
异型条
1.
The formulation and technology of the special material of extruding PA66 profile bar produced for cold bridge by twin-screw extruder were introduced.
介绍采用双螺杆挤出机生产冷桥用PA66挤出异型条专用料的配方及工艺。
2) conditional heteroskedasticity model
条件异方差模型
1.
First of all,the trend term and cycle term are obtained from the original time series by Census X12,which is given a conditional heteroskedasticity model.
首先,利用Census X12分解水文时序,由其得到的周期项与趋势项分别建立相应的条件异方差模型;其次,对于分解序列后得到的残差项,建立基于BX数据生成的灰色Markov预测模型;再次,将三个模型进行耦合,编制了算法流程,由此提出了一种基于条件异方差的水文时序分析与预测模型;最后以河南省淮河流域的鲇鱼山水文站1975-1999年逐月的径流量为例进行了应用验证。
