The first data of geochemical study of the Benevka Section cherty rocks belonging to the Taukha terrane of the Sikhote-Alin Late Jurassic-Early Cretaceous accretionary prism, Russia far east are presented. These data demonstrate essential distinctions of major, trace and rare earth element concentrations in different parts of the measured stratigraphic section. The lower chert horizons exhibit high Fe2O3 and MnO contents, low concentrations of Al2O3 and TiO2, relatively high V/Y ratio, and extremely low value of negative Ce anomaly. In contrast the upper horizons composed of clayey cherts and siliceous mudstones are characterized by high Al2O3, TiO2 and K2O contents, low Fe2O3 and MnO values, low V/Y ratio, and slightly negative Ce anomaly. In the middle part of the Benevka Section, in which cherts gradually changed to clayey cherts, intermediate geochemical characteristics are present. Based on these data obtained the depositional environments correspond to proximal to the spreding ridge, open-ocean and near continental margin regimes were successfully reconstructed from bottom to top of the Benevka Section, that indicate that significant horizontal movement took place of the sea-floor, on which the cherts were deposited.

In this paper, the concept of covering domain is introduced to develop a general expression forthe Fredholm Integral Equations Method, by which elasticity problems of arbitrarily shaped bodies loaded byexternal forces can he solved. Some special expressions are given for a body with non-zero remote stresses, orsubjected to some concentrated forces on its boundary. The relationship between the loading forces andsolutions are also discussed. Some analytical solutions can be obtained for simple cases. When numericalcomputations are needed for the solution, the method proves to have high precision and fast convergency.

The crossed micro-bands in the martensite variant pairs of a thermomechanically trained Cu25.66Zn-4.02Al (wt-%) alloy have been studied. It was found that the micro-bands pass through the interface from one martensite variant to another and their orientation inside different variants is distinct, which would remain in the parent phase after the reverse transformation and play an important role in the formation of preferential martensite. In fact, the crossed micro-bands are micro-twins for accommodating the stress fields generated during thermomechanically training

This article is a theoretical study about ionization equilibrium. Taking the ionization equilibrium of acetic acid in a series of MeOH-water mixtures as an example, we calculated the ionization constant Ka according to the IPF theory, the Born theory and the vander Waals theory, respectively. The results indicate that the values obtained by the IPF theory are in best accordance with those from literatures. A brief discussion about the theories is given at the end.

This article reports a theoretical calculation of solubility product constant of several slightly soluble silver salts in a number of nonaqueous solvents according to the IAF (interaction force) theory based on the interaction free energy of electrostatic, orientation, induction and dispersion. The calculated values of pKsp are in good accordance with those from literature.

By using the drop weight technique in four organic liquid-water systems, the correctionfactor correlation for R/V1/3<0. 3 has been deduced as: =1.007-1.479 (R/V1/3)+1.829 (R/V1/3)*** results show that correction factor is independent of the behavior of wetting and density differencebetween the two phases. The above formula could be applied to the calculation of interracial tensionsof liquid-liquid and liquid-gas systems provided R/V1/3is less than 0.3.

A decision support model with stochastic multiobjective functions and constraints and its solution procedure are presented for selecting R&D projects, in which the uncertainty of project evaluation and selection, the interactions of technique, resource and benefit among projects, and the experience, knowledge and preference of R&D managers are considered. The statistical results of stochastic factors representing the benefit contributions and the three kinds of interactions corresponding to each objective among projects are obtained by the Delphi method and QS/NI decision process for developing the model. In the decision analysis solution procedure, experiences and preferences of R&D managers to make decisions are considered by means of aspiration goal levels(AGL), probabilities to reach AGL called satisfied degrees, and probabilities to satisfy the corresponding constraints called feasible degrees, under which a project selection plan can be proposed by the decision analyst or computer. The utility of this model and solution procedure are demonstrated by a real world case example in R&D program of strength and vibration of aircraft turbine engines. which involves 23 project candidates. The evalutions of benefit contributions and interactions of projects are made by 41 experts in the field.

In this paper, a new approach for generating all or partly efficient solutions called the Combined Approach is developed. The property of efficient solutions generated by the combined approach and its relationships with other four approaches: weighting approach, sequential approach, ε-constraint approach and hybrid approach, are discussed. Based on this combined approach, a decision-making support method called the Combined Decision-Making Method (CDMM) for multiobjective problems is developed, which is an interactive process with the decision maker. Only the aspiration levels, which reflect the decision maker's satisfying degrees for corresponding objectives, are needed to be supplied by the decision maker step by step as he will. This interactive way for objectives can easily be accepted. Finally, the application of the proposed decision making method in the resource allocation problem is discussed, and an example for the production decision analysis of the solar energy cells given.
