Abstract:Nowadays. the paradigms, namely the object-oriented language and the logic programming language, are two attractive knowledge programming languages. However, a generally accepted answer to the question “How to combine the logic-with the object-oriented paradigm for complex knowledge processing?” is still to be given. In this paper, a new model SCKE has been proposed towards combining the logic-with the object-oriented paradigm of computing. It is intended to introduce the concepts that are typical for the object-oriented systems in the logic-oriented paradigm, without losing its advantages as a declarative language. An extensive Herbrand interpretation for SCKE model has been defined to interpret uniformly the logic semantics and the object-oriented semantics. SCKE model has been implemented on SUN separately by the following three methods：precompiling-based meta-level extension, interpreting execution and compiling execution. Finally, the features of SCKE model have been discussed.

Abstract:In this paper“merge”and“pos”functions which can be effectively implemented on modern vector machines are defined. By using the two functions the methods in which forward-if and search-if within do-loops are eliminated have been presented. The general method of vectorization for forward-loops is also discussed. Furthmore, an approach to simplify conditions (guards) of statements execution with the concept of Encapsulation Subgraph is proposed.

Abstract:SBM is a highly efficient synchronization mechanism supporting parallelism on operation level parallel. Based on SBM，we deeply studied the algorithms of node scheduling and barrier placement，and propose an efficient plan for exploiting parallism on operation level. We use a direct graph G(N，A) to describe the dependence among instructions, sort nodes with node's critical path as key words，describe an assignment algorithm that assign the nodes to each processor. Meanwhile，we describe a barrier placement algorithm that inserts the barrier instruction between two dependent instructions if necessary.

Abstract:We investigated the existence and uniqueness of the cauchy problem of semilinear heat transfer equation. We proved that for α>3，if the initial value φ(x) is sufficiently small in some Sobolev spaces，there exists a unique global classic solution for the Cauchy problem. And the solution decays as t→+∞. The method used in this paper makes the value of α be closely combined with the spaces in which the sloution and initial value function are defined. The larger the value of α is，the better the properties of the solution are.

Abstract:Based on three-parameter rotating body model，the relative surface energy，relative coulomb energy and relative rotating energy of deformed nucleus are calculated. These relative energies are all independent of any certain nucleus they might belong to and have generality. They can be used in the calculation of dynamical simulation. According to these results，the deformation potential energies of some nuc1ei are calculated，the calculated fission barrier heights of some nuclei are in agreement with the experimental results. The deformation potential surface of ²³⁶U is drawn and analysed in detail. In addition，the inertial mass and frictional tensors are calculated by means of Werner Wheeler method. Finally，the scission point equation of the deformed nucleus is discussed.

Abstract:A new macrocyclic coordination compound，tetra-(P-methoxyphenyl)porphyrinoxovanadium(Ⅳ)[T(P-OCH₃)PPVO] was synthesized in propionic acid solvent. The composition of T(P-OCH₃)PPVO was determined as C₄₈H₃₆N₄O₄VO? 4H₂O by elemental analysis and EDTA complexometric methods. The UV-visible spectra showed that the formation of the title coordination compound，and the ligand and coordination compound are macrocyclic. Disappearance of the N-H stretching vibration peak in IR spectra of the T(P-OCH₃)PPVO revealed the introduction of the central ion VO²⁺ into the porphyrin ring. The TG-DTA-DTG results demonstrated that the different dewatering mechanism of the ligand and complex are four molecules of H₂O broken away in one step (the ligand)，and two by two stepwise of the four H₂O molecules(the complex). Sixteen distinct lines attributed to interaction of nuclear spin of vanadium(Ⅳ)with the 3dI electron appeared clearly in the ESR spectra of title macrocyclic compound，indicating that its structural model is a distorted octahedron belonging to C_4v point group.
