The thicknesses of the samples (see Fig. 3) were as follows: 0.215 mm (Sample 1), 0.057 mm (Sample 2) and 0.036 mm (Sample 3), the numbering being in order of decreasing thickness.
During this deformation the average size of crystalline grains reduced approximately by 20%, from 45 microns to 36 microns.

Introduction In recent years, ECAP has attracted the growing interest because it is one of the unique methods to produce ultrafine-grained (UFG) bulk metallic materials.
Their number is not limit to one pair.

Introduction Fibre cementitious composite material with a "strain hardening" represents very formable fine-grained concrete with the matrix based on Portland cement reinforced with short fibers.
The number of micro-cracks increases during another load, but the width of each of micro-cracks is not increasing, and remains stable at 60 μm [2] until the time when one of the multiple cracking fails by fracture.

After initiation, the crack propagates by a cleavage mechanism through the small ferritic matrix areas in between the graphite nodules, which measure only one or a few grains.
Thus, a number of microscopic pop-ins are superimposed and cause a macroscopic elastic-plastic appearance of the force-time record, where single pop-ins may not be observed.

One of the issues in terms of growth in local tourism is the occupation occurring on clifftops, which, in addition to coastal erosion (advancing coastline) has led to a number of problems for landowners, the government and the environment [2].
The Dunes are formed by windblown sediments (fine and medium-grained).

Runner diameter 1.7m,Rated speed 600r/min, Runaway speed 962r/min; Maximum head 238m, Minimum head 220m, Rated head 231m; The number of active stay vanes and guide vanes are 24.Sediment particle diameter is 0.5mm,volume concentration is 5%.
The Basic Equations of Solid-phase Grain.

All these cores were broken by hammer, and four kinds of oil sands can be got by screening the broken grains.
The whole adsorption process can be divided into three stages: Stage I: With the increase of polymer concentration, individual molecule accelerates to the surface of adsorbent, and the number of polymer molecules increases quickly on the surface of oil sands.

Today, the method of artificial selection and weight detection to detect defects in the process of plastic blister packaging may product quality problems ，such as the defecting of the drugs, lacking of grain and foreign body, may result in undetected and false detection, resulting in some unqualified products can not excluded timely, it is difficult to popularize them.
The algorithm needs double loop, we can get the total cumulative number is: (10) The two-dimensional Otsu method has a large amount of calculation, the total computational complexity is.

These areas are important bases for grain production, and the research on the spatial and temporal variation of precipitation has practical significance[2].
Empirical mode decomposition method can make non-stationary data be processed smoothly, and make the complex signal be decomposed into a limited number of intrinsic mode function (IMF).

According the above, area of every kind of bio-productive land can be accumulated and the formula of the EF is: EF = N[ ef ] = ∑(wiAi ) = ∑wi ( Ci / Pi) (1) Where EF is the total ecological footprint, N is the number of population, ef is per capita ecological footprint, i is the type of consumption, wi is equivalence factor, Ai is per capita area of bio-productive land to produce the i-th consumption, Ci is per capita amount of the i-th consumption, and Pi is the global average production capacity of the i-th consumption.
Biological resources consumption is mainly include farm produces such as grain crop, cotton, vegetable and fruit, forest products like lignum, animal products such as meat, egg, milk and fur, aquatic products.
