The problem of primary importance in the study of reflection or refraction seismograms is to recognize effective impulse on the records. If a single seismometer were utilized to determine movement of the ground following a shot, it would generally be quite difficult to distinguish with surety the effective waves from spurious energies recorded on the seismogram.

The problem of primary importance in the study of reflection or refraction seismograms is to recognize effective impulse on the records. If a single seismometer were utilized to determine movement of the ground following a shot, it would generally be quite difficult to distinguish with surety the effective waves from spurious energies recorded on the seismogram. In seismic prospecting, the visual identification of effective waves is made possible by the method of simultaneously recording the motion of ground by using as many as 20 to 60 separate detecting seismometers on the same record. The alignment of the impulsive forms across the seismogram is usually referred to as "line-up" or "cophasal-axis" of seismic signal. By using the general probability distribution function of Rayleigh and assuming that seismic waves, are of the Ricker wavelet form, the problem of determining how far random noise statistically limits the detection of seismic cophasal axis in seismogram is studied. The idea that determination of signals of minimum detectable signal—threshold and the dependence of signal threshold on some kinds of parameters was discussed in detail. It may be of interest to mention that signal threshold may be controlled by such interference systems as multiple seismometers, pattern shooting, mixing circuits and magnetic head combination method in reproduction.

This paper mainly deals with the starus quo of the development of nanosecond (ns) framing cameras for image converter cameras, double-proximity image intensifier cameras in our country, and their gate pulse generator circuits. The mixing circuit which consists of avalanche transistor series and pulse chyratron has a short trigger delay time (< 14 ns) little trigger jetter (< ± 500Ps) and anti-interference ability (in strong electromagnetic field), It provides 550V of pulse amplitude, 2. 5ns of rising edge, ≤4. 5ns of falling edge and 15 ns-several hundred ns of pulse width. The shortest frame spacing is 150ns. The circuit with all avalanche transistor series and rapid restorer diode is used for a new version image converter tube being not strict with gate pulse wave. The image converter tube has 10 ns of the pulse width, 50 ns of frame spacing and 300V of output pulse amplitude.In order to achieve high framing rate for image converter cameras, a gate circuit for a trichannel double-proximity image intensifier camera has been successfully designed, based on developing of the double proximity image intensifier camera. Its shortest expo -sure time is 2 ns; the shortest frame spacing is 2 ns; the dynamic resolution of the camera is better than 5lp/mm.The ns pulse gate circuit used for MCP-PMT provides 30 kc(max) of synchronous frequency in the range determined by source power and pulse width, 200 - 300 V of adjustable output square-wave pulse amplitude, 2-40 ns of optional pulse width,≤2. 5ns of pulse rising edge, ≤3. 8ns of pulse falling edge.By having been improved slightly, these circuits described above can be used for controlling low-light silicon target pick-up tubes, for tesing high-voltage instantaneous characteristics for ns pulse source and laser modulation.
