Abstract:An analytical model for the separate type heat pipe exchanger with three different fluids is presented. A univeral basic temperature transfer matrix equation can be applied to predict the heat transfer performance of parallel-or counter-flow in which heat is transfered between one hot fluid and two cold fluids or between two hot fluids and one cold fluid. The calculation of a real engineering example proves the proposal model to be reliable.

Abstract:The rank one updating formula and the parallel eliminating algorithm for linear recurrence systems ane combined fo form a MTMD parallel algorithm fo solve tridiagonal Toeplitz Cinear equations. This algorithm has a simple strictire and requires onlty a few storages as well as in-terprocessor communications. There is no special demand on the number of processors in the parallel system. The speedup can come dose to p12 comparing with the LU decomposition method (p is the number of processors). It is worth pointing out that it is proposed algcmthn that considels and organizes the parallel arithmetic in the first order linear ricurrence systems with constant coefficients.

Abstract:The paper studies a self- scanned circuit used in MOS image sensor with the demand of developing of high -order.low power disspation MOS image sensor and puts forward a kind of self -scanned circuit .which uses a three tramister dynamic nocomparing circuit whith a changing capacitor bootstrap circuit as MOS image sensor. The circuit adopted a silicon gote P -MOS technique, which is a high -speed low-dissipation dynamic no-coparing circuit. It is a practical unit circuit in the high -order array and solves the problem that the power dissipation of array rises with the increase of the array bite.

Abstract:A method of forming the broadband dynamic absorber by paralleling two absorbers is proposed in view of the characteristics of the narrow suppression range of the traditional absorber. The formation of its dynamic model and optimization are studied as well.

Abstract:The structure and features of the CDGTNCP system are described with a design scheme for it to form standard NC subroutines stepwise and assemble final complete NC processing program. By means of file conveyance the integration of GTNCP with CD-CAD system has been implemented . This system adopts the figure-points description to describe componts data ,so that the step description and input of components data are carried out .

Abstract:The basic equations of wall plates of MAN' S dry gas holders are derived in this paper. According to the law of cylindrical bending given by the finite element results .we derive some approximate formula calculating the deflection and stresses of the wall plates from the basic equations. Compared with the known approximate calculating method.the method car. obviously increase the percision.

Abstract:The Existing-form distribution of the seven heavy metals (Cn,Zn ,Pb , Cd .Fe Mn , Ni)in Chongqing life garbages are studed with the tessier' s form group classification and continuous extnaction methods ,Each element's existing-form regularity and moving characteristic are discussed,

Abstract:This paper analyses the additional stray losses of transformer winding caused by harmonics,and suggests that the influence of harmonics should be taken into consideration in the selection of the conductor' s size in rectifier transformer and converter transformer design.

Abstract:This paper proposes a multi - objective fuzzy decision - making approach for power network planning under uncertainty ,which simutaneously considers not only the least investment cost,the minimum power loss,the maximum reliability,and the least environmental impacts, but also the uncertainty about the future load growth and the capital investment availability. The validity and effectiveness of the proposed approach is verified with numerical examples.

Abstract:This paper propsese a new method of getting fault superposed components,with which the high speed ralays can act correctly in the consequent transient process. Digital simul ations have proved the existent problem with the normal method and the correctness of the new proposed method.

Abstract:The snap-back instability (also known as catastrophe behavior) .which may happen during the process of fracture testing with three-point bend round beam of rock .concrete and ceramic materials is analysed,an instability criterion for this kind of specimen is propoesd.it is different from that of the three-point bend rectangular beam.

Abstract:The problem that the micro-glassball is not wettable in molten aluminium alloys can be solved by a special technology that is different from rheocasting and squeezecasting methods. The metten metal can fill the cavity of the glass ball through the broken place on its wall, and an original micro -structure will be formed. This material has good comprehensive mechanical proper ties and this method can be used to other kinds of ceramic powders. The mechanisms of the formation of this materials have been discussed as well.

Abstract:Two methods for load expression in production simulation are studied,and the errors are analyzed and compared when the two methods are used in the direct method of probabilistic production simulation.

Abstract:This papar presents an evolution model in business behaviors-the L-S Business Strategies,gives some examples and predictions which support these strategies,and analyzes the relationship between the industrial organizations in China and the L-S Business strategies.

Abstract:通过深入分析单参数岭估计β（k）的均方误差MSE（β（k），得到了它的一个重要特性。并把较优均方误差的存在范围由（0,σ∧2/maxa∧2γ）扩大到（0.2σ∧2/maxa∧2γ）；同时，还得到了较优均方误差的另一不可替代的存在范围（0，2σ∧2minλγ/（maxλγα∧2γ-σ∧2）；以及最优均方误差的存在范围[σ∧2/maxα∧2γ，σ∧2/minα∧2γ]，并结合实际问题，给出了岭参数k值选的算法实例。
