设有两个非正弦波,其基本频率相等,将此二波变为两电压,接至阴极射线示波器之两对偏转板极,则产生一复杂之李氏图形。此图形之总面积,与二波中基本频率之相角,有一极简单之关系。本文指出此种关系之存在,并引用於电子管放大器及振荡器中相角之测量。

By combining the equation of motion of a magneto-elastically coupled system derived from a classical hamiltonian and the Maxwell equations with the propagation factor neglected, we obtained a differential equation which determines the magnetic oscillations accompanying elastic vibrations of a ferrite specimen of the usual size for magnetic resonance experiments. To each normal mode of elastic vibration of the specimen there exists an associated magnetic oscillation (namely, a magneto-acoustic mode). We pointed out that the magneto-acoustic resonance phenomenon discovered by Spencer and Le Craw is a special case of the parametric oscillation involving a magnetoacoustic and a magnetostatic mode. The arrangements for observing the oscillation involving a certain magnetostatic mode and magnetoacoustic modes and the theoretical estimate of the threshold pumping power were discussed.

在本文中,我们从磁-弹性耦合的宏观表达式,通过经典场论的方法,求得弹性振动和磁振璗的耦合方程,用来分析了伴随波长约等于铁氧体样品的线度的声振动而存在的磁振璗(磁声模)。文中指出,Spencer和LeCraw所发现的磁声效应是磁声模和静磁模在注入场的激发下产生的参量振璗现象(也可以说是热声子的电磁讯号的放大)。我们引用Berk等人在讨论一种半静磁操作放大器的文章中给出的公式,算出Spencer-LeCraw实验所需要的功率,其结果与记录的数据相接近。我们提出了使任一静磁模配合磁声模产生振璗的调谐条件以及降低激发功率和观测几十到几百兆赫的声频的办法。通过磁声模和静磁模的交变场向量的空间对称性的分析,我们推导出磁声参量振璗的选择定则:对于球体三个主要弹性振动模(旋转模、向径模和椭球模),(1)静磁模(n,m,r)的Walker指标n是偶数者不产生磁声效应;(2)指标m是奇数者不与旋转模产生磁声效应,m是偶数者不与向径模或椭球模产生磁声效应。我们也举出第一类本征振动中有只可能和n是偶数、m是奇数的静磁模产生参量振璗的例子。Spencer-LeCraw局限于使静磁场调谐在(110)模上,所观察到的现象仅仅是...

The results presented in this paper may be classified into three categories. First, there is derived the characteristics of gain, bandwidth, and figure of merit of a non-degenerative parametric amplifier of both fundamental and sub-harmonic pumping; and the comparison between them is carried out in substantial detail. Second, there is devised an analytical method for determining the harmonic contents of the capacitance of a nonlinear semiconductor diode, which is negatively biased and is under the action of a strong high frequency pumping voltage. The magnitudes of bias and pumping voltage are thus found quantitatively. Also, the stability requirements for pumping amplitude and pumping frequency are discussed. Third, the noise figure of a parametric amplifier itself and the effective noise figure of the amplifier loaded with a noisy second stage, which may be a frequency converter, are derived. Factors such as diode loss, match, and the bandwidth ratio of the signal to the idler circuit are all considered in the derivations so as to make the results with greater importance for practical applications. Finally, a numerical example is given to show the utility of the results presented in this paper and to illustrate a possible design procedure of a non-degenerative parametric amplifier.

本文主要结果有三:第一,推导出基波激励和次谐波激励参量放大器的优值、功率增益、和通带等主要特性,并就这些特性对基波激励源的和次谐波激励源的参量放大器进行比较;第二,通过半导体二极管非线性电容的谐波分量的分析,在激励电压、偏压和放大器的特性间得出定量关系,并且对给定放大器特性求出激励源幅度和频率的稳定要求;第三,推导出放大器的有效噪声,并给出最低有效噪声的设计条件。 以上特性的探讨和二极管损耗、信号迴路和镜象迴路通带比、匹配等因子结合在一起进行,使所得结果更具有实际意义。最后举出一数字例子,说明应用本文结果来设计参量放大器的一种可能步骤。
