Introduction For a number of years many investigations are focused on the mechanical behaviour of metallic glasses.
This way of the break is observed in flint and other fine-grained minerals, as well as most amorphous matter [2].

However, previous ways of synthesis porous carbon nitride spheres often involve solvothermal method using template, and the walls of the confinement or the removial of the templete often lead to unpredicated forms and shapes of the composites, the incorporation of precursors into the confinement, including an adequate pore filling and adequate mixing and stoichiometry of the starting components inside the pores is hard to control and obeys the statistics of small numbers.
The figures show clearly that after treated under higher temperature, much smoother and continuous surfaces can be observed at the grain surfaces.

However, despite a number of advantages of technology, the production of thermo wood is still limited by a rather small amount of installations the production capacity of which is 5-10 thousand m3 of wood a year.
Grinding of the samples was made on a grinding rack with the help of the Red Wood sanding belt (Bosch) by the sizes of grinding grain 40, 60, 100, 120 mkm.

Due to the higher temperature, the film-forming conditions of FeCO3 can be reached quickly, and a large number of FeCO3 crystal nucleus are induced on the surface of the sample.
At the same time, the growth rate of FeCO3 grains is also very fast, so the metal surface will soon be protected by a layer of dense and strong adhesion FeCO3 film.

After annealed higher than 573K, the deformed specimen begins recrystallization, and form new strain-free grains.
The pinning effect of dislocations will disappear even if the number of dislocations increases.

However, a large number of engineering problems involve the presence of unsaturated zones.
This is the rearrangement of grains due to changing stress, resulting in a reduction in void ratio and instant settlement.

The main problems existed in the production and application of Rhizobium inoculants currently are the insufficient numbers of live rhizobia and severe contamination [5].
Jung et al. (1982) [7] reports that the effective method of preventing multiplication contaminants was to dry the inoculants, but the number of living cells decreased significantly.
The experiment procedures and the calculation of cell numbers and undesired microorganisms rate have been described in our published work [13].

Now, in order to describe the authorized process easier, the number of system user can be assumed as n, and assume that the users who are authorized to access resource No. i at stage No. j is set Ui,j.
So, the state of resource number i in stage j can be expressed as si,j( Ui,j, R, P ), and it means that the user set Ui,j is authorized and permitted to access resource i at stage j, and they become as roles (r, r∈Actions)
The basic design thought [7-8]: A number of occasions on the user's authorization behavior can be seen as an orderly phase, and then consider that the distributed authorization system and authorized system all have advantages and drawbacks themselves.
Those relatively independent resources should obey full trust and synchronization principle to make authorize by using distributed authorization system (DA) in each authorizing, to realize the authorization management in "Coarse Grained".

Introduction The microstructure in 6000 series alloys can be described in terms of grain structure (size, shape, texture), intermetallic phases, precipitates and the matrix; all of which are determined by the alloy content and production processing route.
Although the number of intermetallics identified is small (total 50 particles), the results show a consistent trend for the intermetallics to have a decreasing ratio of Fe:Si (from α → β → π) with increasing alloy Si content. 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1 3 5 7 9 11 13 15 17 19 Microprobe line trace (pos.)

Further SEM-EDS work was undertaken to increase the number of intermetallic particles measured for alloys L1, L4 & L7 in T4 heat-treated extrusions.
