A signal source for use as a frequency source or time keeping signal source includes a radioactive emission source generating a substantially periodic signal corresponding to a radioactive material's disintegration rate. A radioactive emission detector generates a radioactive emission detection signal and, to stabilize the detected periodic signal, a dead time controlling attenuator blanks or shuts off the radioactive emission detection signal for a selected dead time interval in response to each detected radioactive emission (i.e., a detected signal pulse or signal component) generated by the source. The dead time controlling attenuator output provides a long-term and short-term a stable periodic signal.

The invention provides a description method of disintegration characteristics based on a soft rock site state. Based on a disintegration evolution process of a site argillaceous rock state, the disintegration characteristics are described from various angles, specifically four aspects such as a influence depth, fracture rate, particle distribution characteristics and disintegration rate. The influence depth is a one-dimensional linear variable for describing a one-way influence range of disintegration; the fracture rate is a two-dimensional plane variable for describing a boundary feature index of plane disintegration particles and can indirectly reflect particle sizes and distribution; the particle distribution characteristic are three-dimensional variables, and the particle sizes and distribution in the disintegration depth are described; the disintegration rate is a particle distribution value comprehensively determined of a disintegration object. Therefore, the influence depth, theplane fracture rate, the disintegration object particle size distribution and the disintegration rate are comprehensive descriptions of the disintegration characteristics corresponding to developmentstages of disintegration. Compared with the prior art, the method has the advantages that various indexes of the disintegration process of extremely soft rocks can be systematically reflected, and description parameters are closer to actual rock slope disintegration phenomenons.
