1) variable-wise unfolding
变量展开
1.
In this paper,a new statistical batch monitoring approach based on variable-wise unfolding and time-varying score covariance structures is proposed.
针对多向主元分析(MPCA)模型批过程在线监测的缺陷,提出了一种基于变量展开和主元协方差随时间变化的MPCA方法,该方法按变量展开,不需要对新批次未反应完的数据进行预估,而数据之间的动态联系通过时变主元协方差得以保存,并且不需要建模批次的长度相等;将该方法应用于青霉素补料分批发酵过程的实时监测中,结果表明该方法比传统的MPCA方法具有更可靠的监测性能。
2) two-time scales expansion
两时间变量展开
3) Large Independent Variable
大自变量展开
4) variable transformed series expansion method
变量变换级数展开法
1.
Vectorial eigenmodes supported by the buried rectangular and rib optical waveguides are obtained using variable transformed series expansion method.

2.
A multi functional 2×2 multimode interference optical switch based on the deep etched GaAs/GaAlAs optical rib waveguide with spot size converter is proposed and analyzed by using the variable transformed series expansion method and three dimensional finite difference beam propagation method.
提出了一种基于深刻蚀脊形光波导带模斑转换器的多功能 2× 2GaAs/GaAlAs多模干涉型光开关 ,并用变量变换级数展开法及三维有限差分束传播法对其进行了模拟分析与优化设计 。
5) Deformation/Outspreading
变形/展开
6) expansion and variation rule
展开变化
1.
The expansion and variation rule requires that the direction and position of expansion line should be determined by those of the ruche,and the position and shape of the expansion line can be determined by analogy and profile modeling.
