Based on the commonly used mathematical model of the ion flow field of HVDC lines, the relationship between the ion flow field of actual HVDC lines and that of scaled model lines has been derived theoretically. The necessary condition that the scaled model lines has to be satisfied to has also been obtained.

The numerical method is used to calculate the ion flow field under actual HVDC lines and under scaled model lines respectively. It is shown that the ion flow fields of both lines accord with the derived relationship very well indeed.

A field meter,measuring the field above ground level under the DC line,have been developed. Furthermore, lateral profiles of current density and electric field were studied by laboratory models of monopolar and bipolar lines with bundled conductors. The characteristics of ion flow field under 500kV HVDC line were predicted.

The model construction and principle of 500 kV common-tower double-circuit lines was introduced in this paper. On the basis of model line and its parameters,the paper calculated mode line parameters and fixed its composition and parameters(for example: simulating coil impedance,simulating capacitance and simulating parallel reactor parameter),gave the schematic diagram.

In this comprehensive study we present results obtained for the first time from a direct mass spectrometric investigation of the exhaust gases of a high pressure SF6 arc in a model circuit breaker.

However, we have found that besides CF4 also excess carbon is formed, which is deposited on insulators of the model circuit breaker.

The functional significance of male-specific neurons is discussed with respect to their putative receptive field and a model circuit for target location by male flies.

This is demonstrated by an electrical model circuit simulating extracellular recording conditions.

It will be demonstrated, however, that this can be done equally well by means of a further alternative model circuit.

They are interpreted in terms of one of the alternative model circuits shown by Reichardt et al.

The input to the model circuits responsible for the characteristic sensitivity of the SF-system to small-field and relative motion is provided by retinotopic arrays of local movement detectors.

By fitting appropriate model circuits to the data the above listed individual resistances can be deduced.

Our studies of evolved model circuits suggest that, in the absence of other constraints, there is no compelling reason to expect neural circuits to be functionally decomposable as the number of interneurons increase.

Several model circuits are used to illustrate the interpretational difficulties.

This paper discusses an analog neural network implementation for solving primary vision problems such as computing depth from two stereoscopic images, reconstrueting and smoothing images from sparsely-sampled data, computing motion, and model matching. In this paper we put stress on the following questions: 1) Designing efficient algorithms for computing the optimal solution; 2) The computation characteristic and theoretic framework of neural network model circuits; 3) Networks of nonlinear analog neurons which...

This paper discusses an analog neural network implementation for solving primary vision problems such as computing depth from two stereoscopic images, reconstrueting and smoothing images from sparsely-sampled data, computing motion, and model matching. In this paper we put stress on the following questions: 1) Designing efficient algorithms for computing the optimal solution; 2) The computation characteristic and theoretic framework of neural network model circuits; 3) Networks of nonlinear analog neurons which are effective in computing the solutions of optimization problems and may be generalized to solve the nonconvex energy function of vision The results suggest a novel computational strategy for solving primary vision problems so that reconstruction of smooth surfaces from sparsely-sampled data is implemented.
