ジャーナル フリーRecent development in computer-aided “mineral physics” is briefly discussed on three ex-amples : non-empirical quantum mechanical calculation and elasticity-constrained cohesive energy minimization (WMIN) calculation on MgSi03 orthorhombic perovskite ; molecular dynamics (MD) calculation on dynamic structure in high-cristobalite ; and MD calculation on the hypothetical transition of Si02 from the fluorite structure to the α-PbO2 structure. It is hoped that this sort of approach will be accepted by the community of “traditional” mineralogists in Japan.抄録全体を表示PDF形式でダウンロード (1821K) -

ジャーナル フリーImage analysis is now regarded as a new promising technique for material evaluation. In this paper, a computer-aided electron probe micro analyzer (CMA) which was recently developed by the author, is described as a typical example of a new image analyzer, regarding to its principle, apparatus, method and applications. The merits of introduction of image analysis into material evaluation are summarized as follows. Rapidity and reliability of analytical informations are much improved. Moreover, establishment of a new evaluation method, even if its principle is the same to the conventional method, can be expected by the introduction of image analysis.抄録全体を表示PDF形式でダウンロード (7119K) -

ジャーナル フリーBefore the comuper age, many mineralogical and crystallographic data books served as a database in the mineralogical field. Crystal Data and Powder Diffraction Data Files are few examples of pioneering database approaches, which make use of the morden electronic computer. Mineralogical and Inorganic Crystal Database (MINC) has been designed to deal with complex solid solutions of natural minerals and with crystal structure graphics employing connections of cation polyhedra. This database is more efficient to use in mineralogy than ICSD. Some formats to utilize a relational database program dBASEIII have been proposed. As an example of future application of mineralogical artificial intelligence, it is introduced a method of free energy minimization, which has been used to deduce a mineralogical assemblage of the Venusian surface from the chemical compositions and the existing thermodynamic database of the USSR.抄録全体を表示PDF形式でダウンロード (2382K) -

ジャーナル フリーThis paper describes developments in the CHEMICS system for the structure elucidation of organic compounds from spectroscopic measurements. At the first step of the paper, how to generate all the possible isomeric structures from a molecular formula is mentioned. The system has been prepared on the basis of the generation method. The possible parts (components) are provided by the comparison os unknown's data with a set of components preliminarily stored in a computer. Candidate structures are generated using those selected compcnents The number of candidates may be diminished by the operator's knowledge and/or prediction of spectrum for each candidate structure.抄録全体を表示PDF形式でダウンロード (862K)
