    A method of testing stability of sampled-data systems with a relay-type nonlinearity is presented. In the z-domain, a linear sampled-data system which is equivalent to a nonlinear system under steady state condition can be found, and the existence as well as the stability characteristics of the limit cycle can be defined.

    Susceptance of Circular Apertures in Wave Guides
    (交大學刊編輯委員會, 1966-10)

    Tan Chang
    A brief description of the general principles and methods of finding the aperture susceptance of circular apertures in the transverse plane of wave guide is presented. The standing wave method and equivalent magnetic wall method apply only to smaller apertures. For large apertures the variational method is used to extend it to the case of circular wave guide. The results obtained from these methods are found to be compatible.

    The dependence of current amplification factor on emitter current, temperature, resistivities, surface treatments as well as on the radiation effects are investigated. The experiments show that the current amplification factor is more dependent on recombination and scattering mechanism than the other effects. Temperature effect is profound also, high temperature causes high gain(400% at 200℃), low temperature causes very low gain (5% at liquid oxygen). Both the neutron and the Υ-ray irradiation cause the Frenkel defect in the crystal and thus also decrease the current gain preatly. Recovery of gain is obtained by heating at 300℃, 150℃ etc. in dry nitrogen atmosphere and then followed by quick annealing.

    Operational Solution of Inhomogeneous Wave Equation
    (交大學刊編輯委員會, 1966-10)
    陳俊雄
    ;
    C.H.Chen
    The Laplace transformation, the three-dimensional Fourier transformation, and the convolution theorem are used to solve the inhomogeneous scalar wave equation in unbounded space. The solutions obtained consist of retarded potential and a function which is expressed as a superposition of the plane wave solutions. The retarded potential solution contains a unit step function which makes the physical explanation of the result more obvious. Some comments on the four-dimensional Fourier transformation method of approach are also included.

    The Metal-Oxide-Semiconductor(MOS)Field-Effect Transistors
    (交大學刊編輯委員會, 1966-10)
    陳龍英
    ;
    L.I.Chen
    The operation theory of MOS field-effect transistors based on some simplifying assumptions are analyzed. Then a simple method is presented to determine the effective surface carrier mobility, the parasitic resistance in the source region, and the transconductance in the saturation region. Some curves which are necessary in the method are plotted. The saturation drain current and gate voltage of these curves are normalized to the zero bias saturation drain current and pinch-off voltage respectively, thus this method is valid for different kinds of MOS transistors. The curves show that the parasitic resistance may be neglected for most of the practical MOS transistors.

    海鷗
    (1967)
    楊英風
    本件作品完成於1967年，屬於「抽象風格」的作品之一。楊英風於1951年至1961年於豐年雜誌擔任美術編輯期間，曾經親赴霧峰故宮博物院考察，臨摹了許多古代雕塑，深入研究殷商銅器上的紋飾，並進一步將殷商紋飾轉化應用於作品之上，在「殷商風格」系列、「山水風格」系列、「抽象風格」系列裡皆可見到殷商紋飾的元素。本件作品是以一種較為簡化的手法表現出海鷗凌越於海浪之上的飛翔英姿，以接近符號化的簡化線條勾勒出海鷗的型態，而下方則採用殷商銅器上常見的迴紋加以轉化表現出波瀾翻滾的狀態，使作品在現代簡約中又透出一種屬於中國藝術的況味。
