An image display apparatus includes a display having data holding function, a vertical drive circuit sequentially and selectively scanning matrix form display elements, and a horizontal drive circuit writing a voltage among binary voltage preliminarily assigned depending upon the digital data of the image signal. The horizontal drive circuit and the vertical drive circuit are operated for performing selective scan of respective display element for at least m times in one frame period. The vertical drive circuit is constituted of n number of sequence circuits and logic operation circuits for outputs of the sequence circuits, where n is smaller than m, a period from inputting to the sequence circuit to outputting from the final stage being less than or equal to half of one frame period, and at least one of the sequence circuits being used with selectively inputting a plurality of inputs.

Effected by provenance from the depression northeast and the north, sandstones shaped as semicircle,are distributed in the depression northeast ,and then mudstone and silty argillite as its transition to the southwest. The sequence is classified into two types: alluvial fan-braided river sequence, which was formed by the strong tectonic movement in the lower Jurassic, lake-delta-meander river sequence that generated in the middle and upper Jurassic.

由于受凹陷东北部及北部双向物源的影响，砂岩呈半环状分布于凹陷的东北部，向西南部过渡为泥岩、粉砂质泥岩，研究中把层序结构分两种类型：既早侏罗世强烈构造运动形成的冲积扇-辫状河形的砂泥岩碎屑层序、中晚侏罗世形成的湖泊-三角洲-曲流河形的砂泥岩碎屑层序。

Then, the sequence voltages of the slack bus is replaced, and finding the positive sequence power flow several times until convergence comes off. Compared with the three-phase Newton-Raphson method, the Jacobian matrix with the proposed algorithm is of much lower order. The computation of finding the negative sequence component from the coupling power is only division arithmetic.

本文算法中修正方程式的雅可比矩阵阶数同单相潮流算法相同，是传统三相潮流算法的1/3，而通过耦合功率求解负序分量的计算，仅仅是简单的除法运算，计算量远远小于高阶矩阵的处理，因而总体上，与传统方法相比，大大降低了计算量。
