In this paper, the series resistance and cutoff frequency of diffused parametric diode are analysed. The way of finding out the optimum impurity distribution for a given material has been indicated, and the way effectively to increase fc has been shown.

当存在着掺入杂质的补偿作用时,如何正确地估计扩散参量二极管串联电阻的问题至今未获解决。所有关于截止频率f_c(通常用f_c估价二极管)的讨论都是极不全面的,甚至导致错误的结论,远不能满足实际的研制需要。本文的目的在于给出计算串联电阻比较妥善的方法,阐明影响f_c的基本因素及其提高的有效途径。

From the point of view of fracture mechanics, we studied the far displacement field produced by a disk-shaped pure shear fracture and obtained an analytic expression for that field. Then, by using this expression we calculated the form of the impulse and its spectrum and found a relation between the corner frequencies fcα,fcβ of the P and 8 waves and the fracturing radius of the earthquake focus, i.e. fcα = 0.6/t2α = 0.6/al/vr + π/4α) and fcβ = 0.45/t2β = 0.45/a(1/vr + β/4β), where t2α...

From the point of view of fracture mechanics, we studied the far displacement field produced by a disk-shaped pure shear fracture and obtained an analytic expression for that field. Then, by using this expression we calculated the form of the impulse and its spectrum and found a relation between the corner frequencies fcα,fcβ of the P and 8 waves and the fracturing radius of the earthquake focus, i.e. fcα = 0.6/t2α = 0.6/al/vr + π/4α) and fcβ = 0.45/t2β = 0.45/a(1/vr + β/4β), where t2α and t2β are respectively the average values on the focal sphere of the impulse widths of the earthquake focus of the P and S waves, vr is the velocity of fracturing, taking as 0.775 β;α,β are the velocities of the P and 8 waves. In neglecting the delay factor of theray paths e-iwr/c, the effect of the absorption of the media resembles a minimum phase-shift filter. Employing Hilbert Transform, the frequency response .B(w) =exp of the media was found, in which t*=r/CQ, where r, the distance from the earthquake focus; c, velocity of waves; Q, quality factor of the media and wm, the high cut frequency. This expression is different from that of Futterman. After taking into consideration of the effect of the absorption of the media and the frequency characteristics of the instruments, the earthquake focal dimension 2a and the seismic moment M0 in the frequency domain were obtained. While in the time domain, fast Fourier Inverse Transform was used to get the impulse response of the media and the instruments and then convolved with the impulse of the earthquake focus to construct the synthetic seismogram. From it we can get the relation between the initial half period T2P and the dimension 2a or impulse width t2α of the earthquake focus. Then draw the nomogram for this relation. From the nomogram we can get 2a, the focal dimension. The value is essentially the same as that obtained in the frequency domain.Based on the relation Ms = 21og(2a) +1/1.5, as the outcomeof the study of fracture processes of the earthquake focus in the light of frecture mechanics, we were able to find the regional shear stressτ0 of the Peking-Tientsin-Tangshan-Zhangjiakou area. Here, η, efficiency of rediation of the earthquake, taking as 0.05: v, Poisson Eatio, taking as 0.252; μ, rigidity modulus, taking as 3.3 1011 dyne/cm2. Computations show that before the Tangshan Earthquake of July 28, 1976, the stress value of the Tangshan-Fengnan area was the highest, reaching a value of 870 bars. But in the Changli area, at a distance of about 100 km away, the stress had a value of only 200 bars. After the Tangshan Earthquake, in the Tangshan-Fengnan area, located in the central portion of the earthquake fault zone, To dropped to 100 bars. However, at both ends of the fault zone, the stress was still very high in value, especially at the southwestern end, in the vicinity of Ninghe, the stress value there was 400-500 bars. Until November 15, 1976, a strong aftershock of magnitude 6.9 occurred here, after which the stress value decreased to 200 bars.
