To infer flow information from a particular constituent in the multiphase reactors, particles marked by radioactive materials can be introduced into the equipment to label the constituent either as a single radioactive tracer or as a cloud of radioactive particles (Shehata et al. 2005).
Materials and Methods The radioactive particle required for a RPT experiment depends upon the process fluid being tracked.
In CT slices the denser the scanned material the brighter the image.

The significant property of fly ash is increasing the durability of materials [1,2].
Therefore, to develop the friendly environmental materials and local economics, this material would be another good alternative.
Fly ash addition in clayey materials to improve the quality of soil bricks.

Introduction Ball milling (BM) is one of the possibilities to prepare materials with exceptional mechanical and magnetic properties.
Because of the very fine grain sizes, nanocrystalline materials exhibit a variety of properties that are different and often considerably improved in comparison with those of conventional coarse-grained polycrystalline materials [2].
The values of Mr/Ms were less than the corresponding values for the same polycrystalline materials.

The bulk UFG materials free of porosity produced by ECAP provides new opportunities to study their properties in comparison with conventional coarse grain (CG) materials.
According to MiloŠ [8], the corrosion damage is more homogenous in the ultra-fine grained materials and the clear localized intergranular corrosion in coarse grained material.
UFG materials produced by ECAP decreased the localized corrosion for ultra-fine size and uniform grain.

Introduction Computer-aided translation is a rapidly developing technology with the coming of the electronization of materials pending translation.
While the translator is doing his work, the memory bank of translation is involved in continual learning and storing new version of translated materials to establish language database.
The mainstream software of CAT has Translation Memory (TM), the storage of the database of the translated materials and segments, as the core technology.
TM allows the translator to avoid the repetitive translation work and helps maintain the continuity in the translated materials.
The more frequent communication in international field has created the need for more materials to be translated.

Vibration absorbing materials are used such as rubber mounts, pads, or springs.
Materials used are based on the noise frequency, desired reduction, and environment.
In order for barriers to be effective designers must use the proper absorption materials.
These materials can be heavy, expensive, and take up critical space.

Now, steel materials were used on most drive wheels in domestic, so the research on new material of wheels would make great contribution to cost reduction.
According to GB / T 228-2002, the test bar tensile test was taken on the wheel material and carried out the the material characteristics curve of spheroidal graphite cast iron materials.
As the material was brittle, there was no obvious yield point. so the stress occurs at the 0.2% plastic deformation was taken as the yield stress, The material characteristic was simplified to bilinear elastic-plastic material model with dynamic Track material was low alloy high strength structural steel Q345b, with good mechanical properties and good performance on low temperature, which was typical elastic material.
