摘要：
The conditional entropy and mutual information of two neighboring generations of division are proposed as characteristics to use in analyzing the random cascading mechanism in multiparticle production. It is shown that these characteristics are effective in examining the existence and property of self-similar cascading, provided the multiplicities of the events in consideration are high enough.

摘要：
We report on an attempt to determine the microstructure of a FIM specimen directly by its field ion micrograph combined with field evaporation. In this paper the general idea and presumptive procedures of the method are described. In a following paper the determination of the body-centered cubic structure of tungsten obtained by a manual method is reported. The same work performed by a digital video image acquiring/analyzing station is reported in the third part, which is the first stage in realizing our objective.

摘要：
By using FIM, high-transition-temperature superconducting Bi<inf>2</inf>(Sr, Ca)<inf>3</inf>Cu<inf>2</inf>O<inf>y</inf> has been examined with H<inf>2</inf> and Ar imaging gases. Two kinds of FIM images, lines and spots, have been observed and analyzed. Both patterns convincingly show the lamellate structure of the specimens. The periodicity of the FIM image patterns is consistent with the proposed models, and some new patterns are observed and discussed.

摘要：
We derive equations for the single and joint probability distribution of systems driven by colored Poisson noise using the ordered cumulant technique. We also derive the equation for the correlation function. We discuss an example for which the correlation function and the associated relaxation time are calculated.
