DDIAGRAMS: A GRAPHIC MEANS FOR DATA DESCRIPTION
V. N. Ogibin, V. H. Shmakov VANT. Ser.: Mat. Mod. Fiz. Rroc. 1989. Вып.1. С. 38.
We propose a graphic means for complex structure data description. Data organization relies upon three structure types (fetch, direct product, sequence) and three nonstructure types (integer, real, string). For each type, a graphic image is found to match it. Two ways for data representation are examined along with data type definition: the first is to store, the second is to display or to print. Using Ddiagrams is exemplified by several real applications.

DETERMINING GROUP CONSTANTS AND ACCOUNTING SCATTERING ANISOTROPY
V. М. Shmakov VANT. Ser.: Mat. Mod. Fiz. Rroc. 1989. Вып.1. С. 4851.
An approach suggested for constant determination is to maintain a number of characteristics in a neutron flow which occurs after the interaction with a target neucleus when the scattering anisotropy is accurately or approximately described. The requirement that a number of associated harmonics in a resulting secondary flow, material breeding properties, energy release and intergroup transition matrix elements should be retained, gives formulae for a generalized transport approximation of scattering anisotropy. Restricting crosssection correction value leads to physically noncontradictory values for intergroup transition probabilities.
