Decisions about material procurement may also be required during the initial planning and scheduling stages.
The availability of materials may greatly influence the schedule in projects with a fast track or very tight time schedule: sufficient time for obtaining the necessary materials must be allowed.

Key Words: vibrating sieve, ultrasonic wave, controlling system
Abstract: The present thesis proposes the controlling program to separate the particle materials by making use of low-frequency ultrasonic wave, and elaborates the design of system circuit controlling the ultrasonic vibrating sieve.
Introduction Separation of particle materials is an indispensable program and process of industrial manufacture.
By inputting the ultrasonic transducer, it introduces a low amplitude and high frequent ultrasonic vibrating wave onto the screen on the basis of traditional vibrating sieve for improving the screening performance of superfine Materials.
Interconnecting the 3525 chip with peripheral circuit to generate the main frequency of ultrasonic wave, enlarging the output current by power amplifying circuit and producing the additional wave by SCM(Single Chip Micyoco)for fine adjustment, the system is able to separate the materials by vibrating the screen rack which is moved by transducer.

Introduction
Concrete is a kind of manufactured materials which is the most widely used [1].
At present, nano materials that researchers usually used to modify cementitious materials were nano-SiO2, nano-clay, nano-Al2O3, nano-Fe2O3 and nano-CaCO3.
When the content of NA was 2%, the machanical properties of modified cementitious materials were improved most.
So to different nanoparticle, it had the optimal content to modify the properties of cementitious materials.

Abstract.
Architectural surface materials in 2 d space on the composition of the main is to emphasize material and material as the two dimensional space compositions of skin materials mainly emphasize the relevance among different materials and the combination rule of material order.
Through the superposition and integration of construction materials or between the building materials and energy-saving components, the forms of two-layer or even multilayer are presented.
The three- dimensional reverse of architectural surface materials.

The direct extrusion process using the mechanically alloyed powder as raw materials was applied to prepare the thermoelectric materials.
But, the Z value in randomly orientated p-type material is about 6% less than highly oriented materials [1,4].
The doping method has often been applied to improve the Z value of the thermoelectric materials.
