Secondly, overcoming drawback of single variable fitting ar models lacking of other variables acting on factor variable, a set of the trace formulas are given about the time - change coefficient matrixes of multivariable fitting ar models
2應用逐段線性化的方法推導出了多維ar （ r ）自適應模型時變系數矩陣的遞推公式，克服了單變量ar （ r ）自適應模型沒有考慮其他變元對因變元的作用的缺陷。 -
The low - ti series show variable degrees of nb - ta depletion in primitive mantle - normalized spidergrams with slightly enriched to depleted nd isotopic compositions, whereas the transitional series exhibit similar geochemical features to emii - oib and have transitional characteristics between the high - ti and low - ti rocks. all three groups show no continuous shift in major and trace elements and cannot be regarded as different phases during magma differentiation process. on the basis of normalization to mgo = 8 %, the high - ti diabases have the lowest sig, nag and highest tig and peg
通過詳細的巖石學和元素-同位素地球化學研究，這些巖石具有各自不同的地球化學特徵，其中高ti系列的低la nb 、 zr nb比值和虧損的nd同位素組成顯示其類似於oib的特徵，過渡ti系列則顯示出emii - oib的特徵，而低ti系列則高la nb 、 zr nb比值和變化的nd同位素組成顯示出一定比例的富集巖石圈地幔或地殼物質的參與。 -
State observer is a realizable dynamic system in practice. it is driven by the input signal and output signal of the observed system. its output can trace the state variable of the observed system properly
所謂狀態觀測器就是一個在物理上可以實現的動力系統，它在被觀測系統的輸入輸出信號的驅動下，產生一組輸出，使得該輸出能夠很好地逼近被觀測系統的狀態變量輸出。
