We also issued one method to value the logistics schemeBase on these research, we build the logistics model of integrate prototype build programs, defining the restriction checking method and fundamentalsThe achievement has been applied to the design and optimization of our technical center’s integrate prototype build programs in 2008.

This paper presents the cause of the false image of sample preparation,some of conditions influenced on sample preparation results,many factors influenced on materials remove and matters needing attention in modern sample preparation technology,while some related traditional wrong knowledge would be corrected.

Based on these problems , authors gave a minute description of sample preparation , adhesive , rendering coat mortar , mechanical fixings site drawing and coefficient of thermal conductivity.

The process of sample preparation and gold separation?enrichment and determination was discussed briefly.

The present paper introduces the method for measurement on the chemical compositions of the coal ash by X-ray spectrofluorimetry,discusses the prerequisite to the measuring devices,selection of conditions for specimen preparation and method for preparation of the combined specimen and checks and tests the accuracy and correctness.

A new specimen preparation method was presented that the specimen was ion milled directly after mechanical pre-thinning.

Defining the remolded soils,apprehending characteristic of remolded soils frame,and choosing the suitable craft of preparation of sample are very important in obtaining the experimental parameter of physical and mechanical properties for remolded soils.
