Analysis on the characteristics of transient signal transmission based on GaAs materials Wei Liu1, a and Tian Lan2 1Department of Physics, Capital Normal University, Beijing 100048, China 2School of Opto-Electronic Engineering, Beijing Institute of Technology, Beijing 100081, China alwei263@263.net Keywords: GaAs semiconductor, Photoconductive switch, Ultra fast, Transmission model, Time resolution Abstract.
It is made up of the materials with high density of imperfection and extremely short carrier lifetime, including low temperature GaAs (LT-GaAs) and semi-insulating GaAs (SI-GaAs) etc, which make the photoconductive switch works in the range from nanoseconds to picoseconds.

However, the viscosity is increased with amount of nano materials, which makes the rheological behavior bad.
The experiment shows that the addition of nano materials can improve the compactness and quality of the filter cake and reduce water loss by affecting dehydration and rheological behavior.
Calcium carbonate superfine powder, non-permeate pressure-bearing agent CY-1 and nano materials were optimized at the same time.

Accordingly, development of current yoghurt packs and PP based materials has been initiated in labs with the help of food, chemistry and material science.
Parallel to technological developments, there is a trend for usage of intelligent materials in material science.
This trend results in incredible studies not only on metallic materials but also on polymer materials.

Composite materials refer to engineered or naturally-occurring materials made from two or more constituent materials with significantly different physical or chemical properties.
To ensure the sustainable development of building materials, the key is research and development and promote the use of green building materials.

Footwear nesting were based on its design pattern and manufacturing materials, the results of nesting influence the products quality and cost directly.
Because the clothing sample size are generally apparels, and the used materials are unitary.
Pattern recognition with materials is point to digital expression model in a computer; it’s the premise of Computer Aided Nesting.
Rectangle method is the most commonly used method for most materials, but for those with rectangular shape far parts, only combined different or same parts into an approximate rectangle, so as to improve the utilization rate of materials.

Materials 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.
(material ordered very late – buffer at supplier, material ordered very early – buffer at site) 0.643 6 The size of construction site and material storage location - labors require extra time to move materials. 0.629 Table 3 shows materials issues in construction project as ranked per relative importance index analysis.
