标量数据 meaning in English
scalar data
Examples
- These data consist of scalar data ( temperature , pressure , etc ) and vector data ( velocity , etc ) , which are commonly defined on unstructured grids with complex topology
这些数据类型比较复杂，既有温度、压力等标量数据，又有速度等矢量数据，而且它们通常定义在非规则网格上的拓扑关系也很复杂。 - What the practical problems is often gotten is a single variable time series which has a time interval of t , reflect by a lot of interactive physics factor , containing the mark of all variates participating in movement , traditional time series analysis is to analyse going from this array to the form directly it ' s time develops , one dimension analysis loses useful information , the characteristics of phase space reconstruction method is to construct one dimension scalar quantity to high dimension vector , prop the geometry space of the state , show all dynamical information of system in phase space . the characteristic that just constructs again according to the phase space in this text , analyse the time series of responding , use the relevant knowledge of symbol dynamics and reconstruct phase space , put forward a kind of relation degree analysis method of the systematic mathematics model which has theory basis , so reach the correction of calculation mathematics model , make it accord with the actual systematic state
实际问题中常常得到的是一个时间间隔为t的单变量的时间序列，它是许多物理因子相互作用的综合反映，蕴藏着参与运动的全部变量的痕迹，传统的时序分析是直接从这个序列去形式地分析它的时间演变，一维分析必然丧失许多有用信息，相空间重构方法的特点是把一维标量数据构造成高维矢量，支起状态的几何空间，在相空间中展示系统全部动力信息。本文正是根据相空间重构的特点，对响应时间序列进行分析，利用符号动力学、重构相空间等方法，提出一种有理论依据的系统数学模型关联度分析方法，从而达到修正计算数学模型，使其更符合实际系统状态的目的。
