On utilizing the half-sections of a minimum inductor image-parameter band-pass filter as suggested by C. C. Koraн, the formation of a composite filter requires such processes as equivalent network transformations and impedance-level transformations.Owing to the relatively complicated form of the coefficients of network elements, calculations usually turn out to be laborious. In this paper steps are considered with the aim of simplifying the overall computations.The paper starts with a discussion of some of the relevant equivalent circuits, and after introducing the symmetrical relationship of the theoretical cut-off frequencies x1 and X2 together with the expression of definition of the parameter n, succeeds in establishing certain typical composite sections with compact expressions of normalized element coefficients, as shown in Table 2, by mears of which it is easier to obtain a composite filter with a minimum inductor. Examples are given at the end of the paper to illustrate the steps involved.

最少电感元件带通滤波器具有电感元件数目最少的优点。在利用所提出的影象参数最少电感元件带通滤波器各种半节来构成复合滤波器时,其复合过程一般比较复杂,通常要经过等效网络变换、阻抗水平变换等步骤才能合并,由于这种类型结构的元件系数计算公式形状较繁,所以更增加了应用时的不便。本文讨论了一些相关网络的等效电路,在引进理论截频的对称关系及通带参数n的定义式后,得出了等效网络的比较简洁的表示式及其在极端值时的各种衍生结构。由此可以建立一些典型的复合节,利用这些复合节,并加上适当的阻抗水平变换后,可容易地获得所要求的复合滤波器。

This paper establishes a new conceptual model for snowmelt runoff forecasting in real-time by using the equation of continuity and second-order diffuse equation in hydraulics. According to Jones′ formula that (?)Q/(?)≈1/C (?)Q/(?)t and difference equation, the author derived that an one-step ahead predication model could be written asQ_(t-1)=A_(t)Q_(t)+B_(t)I (?)+G_(t)I(t-1)Let the sonw coverage of the basin as input, we can forecast the snowmelt runoff in real time. The results are satisifactory.
