In China, medicine tends to go through six or seven links from pharmaceutical enterprises to the patients including the process: the supplier of raw materials——pharmaceutical enterprise——region general distributor——district distributor——hospital——patient while in developed countries, the links of pharmaceutical supply chain consist of the supplier of raw materials, pharmaceutical enterprise, hospital and patient.
Research on pharmaceutical supply chain management based on RFID The entire business of pharmaceutical chain management involves the relevant regulatory authorities, pharmaceutical raw materials, pharmaceutical enterprises, its distributors at all levels, hospitals and consumers.

At this temperature the raw powders begin to diffuse together and the solid-phase reaction between the raw materials begin.
We can also observe the neck phenomenon causing by the diffusion of the raw materials.

Since cement-based materials are considerably used in constructions, determination of thermal conductivity of these materials is of great importance.
In a theoretical study, proposed to represent complex materials as composites made of materials perfectly represented by one of the four following models: series, parallel, One-dimensional heat flow and Maxwell’s model.
