From noise voltage frequency spectral data Ss(ω) taken from carrier channels along many transmission lines in China, relative power spectra are calculated. Then by step-by-step integration method, the equations for corresponding correlation coefficients, or normalized autocorrelation ρ ate derived in terms of Ss(ω) and difference time τ. The shapes of the calculated ρ-τ curves are in general irregular, but in several cases where maximum Ss(ω) occurs at lower measuring frequency, p-r curves resemble the shape of damped cosinusoid e-aτ cos 2 πf τ. Finally the following parameters are calculated: thedifference time τ1, τ2 and τ3 at which | ρ|≤, | ρ|≤1/e2 and | ρ|≤ 0.05, exponentialattenuation constant a, average frequency and no. of zero crossings N, in intervals τ1, τ2-τ1, τ3-τ2 and τ3. It is found N/τ3f= 2, τ3 determines the upper limit of frequency ofsignal envelope for optimum reception. When higher carrier frequency (>40000 Hertz) is used, τ3 is usually smaller, this upper frequency limit 1/τ3 becomes higher.

根据在我国各区电力线路上测试的噪声频谱密度数据Ss(ω),先算出相对功率频谱密度,再用逐段积分法,求出相关系数ρ与相差时间τ的关系曲线。 在大值由Ss(ω)集中在一个较低频率的几个情况下,ρ-τ曲线的形状相当接近于e~(-ατ)cos 2πfx;在大值Ss(ω)比较分散的一般情况下,它的振荡形状是很不规则的。 最后算出|ρ|开始小于1/e,1/e~2与0.05的相关时间τ_1,τ_2与τ_3,以及在分段过程τ_1,τ_2-τ_1,τ_3—τ_2和整个过程τ_3中的平均振荡频率f,指数衰减系数α,过零点数目N等,其中N/τ3f很接近于2。第一分段τ_1中所得的参数和整个过程τ_3中所得的平均参数相差很远,因而第一分段的参数不能表示整个过程的特征。τ_3决定着通道中不积累误差的载波包络的频率高限。一般地讲,如果在通道中使用较高的载频(4万赫以上),所得的τ_3较小。因而可用较高的载波包络频率,也就是信号频率可以提高些而不致降低信号噪声比。

A new quantity -maximum correlation time-is introduced to describe thephase relation between the daily variations of the vertical component of geomagnetic field at two stations. The maximum correlation time is computed by using adequate data processing technique from the hourly readings of vertical component at the Peking and Wuhan stations. The mean value of the maximum correlation time is shown to be nearly equal to the difference of local times for these stations. Moreover, it exhibits remarkable seasonal variation which has a period of one year and ranges to about 0.7 hour. Fourier analysis of the maximum correlation time shows that it also conta-ins two appreciable harmonics with periods 29.8 ± 0.6 and 13.7 ± 0.2 days respectively,, and with amplitudes of about 0.06 hour for both harmonics.

The phase relations between the daily variations of the geomagnetic field at Sheshan (佘山)amd Lunping (崙坪) Geomagnetic Observatories are described by using the concept of maximum correlation time. The data of the vertical component and the declination in 1974 were used, and the maximum entropy method (MEM) was applied to the results of the maximum correlation time series. It shows that there is a remarkable harmonic variation with a period of 14.6 days. This may be due to 'lunar ocean dynamo', as suggested by the author. When the lunar oceanic tide current flows along the East China Sea and the Taiwan Straits (a conducting channel), it will cause different magnetic fields, e.g. both in direction and in magnitude for Z, at the coastal stations located at both sides of the strait. Therefore the maximum correlation time presents the lunar semi-monthly variation.

本文用最大相关时间的概念研究佘山台和仑坪台地磁场日变形态的位相关系。处理了1974年垂直分量和磁偏角的资料。用MEM分析了最大相关时间变化的功率谱,结果明显地揭示出它含有周期为14.6天的变化。对此现象,本文提出一种可能的解释,即部分海洋月相潮汐电流沿东海经台湾海峡(导电通道)时,在海峡两边产生的磁场变化存在差异,因而形成最大相关时间的半月周期变化。
