Introduction The authors have been investigating various uses of microwave (2.45 GHz) and millimeterwave (83 GHz) systems in material production and processing for a number of years.

Compared to traditional backup solutions, they provide fine-grained data backup and recovery.
A number of projects such as Peabody [11], TRAP-Array, Venti and Clotho [12,13,14], have highlighted the importance of log growth and provided effective method to reduce storage space.

Waste plastics have been studied by a number of research organizations for use as reinforcement or aggregate in lightweight concrete products [1,2].
In order to adequately encapsulate aggregate grains, a larger aggregate content decreases binder thickness [11-13].

The element numbers for the specimens with the stress concentration factors of Kt=4.9, 3.3 and 2.1 were 2,376, 2,376 and 2,144, respectively, with a minimum mesh size of about 0.5 µm and fine meshes arranged in the region near the notch root.
A square root relationship between local decohesive stress and hydrogen content was also suggested on the basis of experimental results of grain boundary strength [14].

Nevertheless, the improvement obtained in this way is quite limited, and it results in operational complexity and requires rather large number of spare parts.
Firstly, ferrous oxide powder of small grain size formed during annealing process and attached to strip surface.

Later, some scholars began to perform an analysis on the river channel change using diffenren method, such as, aerophotography (Leys & Werritty,1999), analysing the river width, depth, volume, sediment grain size (Vanacker, 2005 ), and based on the geomorphology (Gregory,2006; Li et al., 2007 )[9-12].
Drainage complex rate (CR) is used to describe the how well the length and the quatity of the river network develop, the bigger the number, the more complex and stable the structure of the river.

However, despite all its advantages, cement has a number of significant disadvantages.

Desorption rate [m-2 s-1] = (M - M0) [A] × (S�K) [mol A -1 s-1 ] × NA [mol-1 ] / A [m2] (2) Where M represents the signal intensity of desorption hydrogen from specimen and chamber, M0 the signal intensity of desorption hydrogen from chamber, NA Avogadro's number, and A surface area of specimen.
In fact, as shown in Fig. 7, SEM observation demonstrated that oxide grains comprising the oxide scale formed in N2-2.4%O2-19.7%H2O seem to be isolated.

In addition, one can also improve the ductility of these alloys by incorporating the disordered secondary γ-phase (A1) in the matrix, in particular along the grain boundaries [8-9].
The reduction of the transformation strains and the increase of the thermal hysteresis under both stress states is attributed to the number and resulting interaction of martensite variants that form at higher stress levels, which will trigger stress-induced martensite along with the thermally-induced martensite [14].
