Through establishing a shared saving model,the optimal proportion of shared saving for maximizing supplier,manufacturer and the whole supply chain profit has been calculated.

In order to give the best proportion of cement to fly-ash for coustructing cement-fly-ash stabilized crushed-stones pavement,through varying the proportion of cement to fly-ash while maintaining aggregate percentage and gradation,the variation law of mixture strength index with age is studied by experiment.

Finally we propose an efficient algorithm for constructing wavelet block quantization tables with optimal bit allocations for a given image.

In this paper,experimental study on sintering properties of materials used in XIANGTAN I&S Co ,ltd was presented In order to gain good product quality and low cost,the optimization of mix proportioning was conducted As a result,the optimum proportioning ratio at present raw material source conditions was obtained,and the direction of raw material sources modification was also indicate

as a result, the optimum proportioning ratio at presnt raw material source conditions was obtained,and the direction of raw material sources modification was also indicated.

To balance accumulation and allocation takes an important role in public hospitals continuous development.

Biomass of Chinese fir plantations in Fujian Province and its allocation among leaf, branch, stem and roots were studied based on the published biomass data.
