The total limiting water content within the rice grains was calculated and it agreed with that calculated from the known water/rice ratio used, indicating that both the concentration and distributions of water within the rice grains during cooking obtained from the NMR imaging were quantitatively reliable[6-8].
Parameter settings were: receiver frequency: 19.502MHz; pulse width: 50us; sampling number TD=8129; echoes number C0=380; repeated scanning number NS=16; repetition time D0=4s.

In nanocrystals, since the surface to volume ratio is much larger, there is an increase in the number of atoms on the surface compared to the number of atoms inside the particles.
Fig.4 shows a remarkable shift in peak position as well as in asymmetry of the Raman line towards higher wave number due to change in grain size [12] or the surface phonon effect due to small dispersion of LO phonon wave vector in the samples.
The change in grain size affects the vibrational properties.

Therefore, the influence of stripe numbers on critical loads are further studied for higher anti-buckling enhancement.
Compared with the critical loads of the above models, it is found that with the stripe number rises, the critical loads increase at first and then decrease, thus too many vertical stripes will depress the anti-buckling enhancement.
While when the vertical stripe number rises, the critical load increases first and then decreases.

The investigation on the performance of flood protection systems at home and abroad during a flood seanon made reference to a number of cases where signs of underseepage piping erosion may have occurred and contributed to the failure of the levees [1, 2].
According to a larger number of filed observations, initial phenomena of piping are different.
Some appear to be moderate, just out of water and sand boiling, the others show that a larger number of sand blast out intensely and the ground collapse.

Introduction
The composition of essential amino acids in oats are basically the same as the standard that adults daily intake, it can effectively promote the growth and development of human body and the amino acids of the protein in it is the most balanceable of all the grains[1].There are more researches about the application of oats in oatmeal, beverage, noodles and bread[2-5], it has important researchful significance to add the oat flour to the Quick-frozen dumplings and develop a new kind of Quick-frozen oat dumplings and study the application of oat in quick-frozen prepared food.
Dumpling freezing and cracking rate calculated in accordance with the following: frozen cracking rate(%)=B/A×100% Where A is the number of experimental dumplings, B is the number of the cracking dumplings.
Rating Panel is composed of five members, randomly select a number of samples of dumplings to taste and score, taking the average with two decimal places.
Oat flour does not contain the gluten protein, after adding oat flour in the flour, it dilutes dough gluten network structure, the more grains add the more multiples that the gluten network structure is diluted and the higher the cracking rate of the quick-frozen dumplings.

Fig. 3a shows the grain arrangement typical of t-ZrO2, (ZrO2-nda, the corresponding XRD pattern is
shown in Fig. 1b).
The non-uniform sizes of voids between the oxide grains were responsible for the well developed micro- and mesoporosity characteristic of the aged ZrO2 samples.
Such an interplane distance has already been found in the HR-TEM images of t-ZrO2 grains [28], but so far cannot be univocally attributed.
The number of interparticle contacts increased, the structure is less open and strongly agglomerated, also manifested in the collapse of the pore structure [17].
This coherent crystalline ordering can be observed within the whole grain and ends sharply at grain boundary.

These properties are strongly dependent on the microstructure and magnetic behavior of the
crystalline grains created during the primary crystallization process.
Indeed, the spectra show multiple narrow lines corresponding to structurally different crystallographic sites assigned to the crystalline Fe, Si grains, superimposed to a broadened spectral line ascribed to the remaining amorphous phase [12,13].
The fitting model consists of three main components: two sextets of Lorentzian lines attributed to the Fe-atoms situated in the bulk of nanocrystalline grains and one individual subspectrum resulting from the distribution of hyperfine parameters ascribed to amorphous residual matrix.
The fitting model contains two main components: one sextet of Lorentzian lines attributed to the Fe-atoms situated in the bulk of nanocrystalline grains (α-Fe grains) and one individual subspectrum resulting from the distribution of hyperfine parameters ascribed to amorphous residual matrix.

The grain size of the samples was analyzed using the Laser Particle Size Analyzer Mastersizer2000 produced by Britain, accomplished in the Ministry of Education Key Laboratory For Coast and Islands Development, Nanjing University.
The grain size parameters computation used the Moment method in (Jia J J et al., 2003).
When comparing grain size of ZXY01 with ZXY02, the content of clay and sand of ZXY01 were more than that of ZXY02, and the change from top to bottom was greater.

A number of authors have reported that materials with a high value of strain hardening exponent allow more tensile deformation before a localized neck develops and hence enjoy the benefits of cold working [17-19].
The primary ferrite (dark) dendrites having a combination of lathy and vermicular ferrite morphology contained in austenite (white) matrix, and a precipitation of carbide along grain boundaries.
Carbide precipitation was also observed along the grain boundaries.
The interdendritic ferrite (dark) had a vermicular morphology engulfed in the austenite matrix, with carbide precipitation along the grain boundaries. 3.2 Effect of Electrode Covering on the Properties of Austenitic Stainless Steel Weld Metal The results also suggest that the type of electrode coating has effect on the weld metal properties.
The results of true stress-strain graphs and Engineering stress-grain graphs for selected materials are displayed in Figs. 7 and 8 respectively.

The epitaxial growth on single Pt grains is well visible (from [12]).
During further growth, a dens fibrous, columnar grain structure develops.
Atomic (001) planes meet at grain boundaries as if adatom diffusion crosses grain boundaries.
Such grains behave as single crystals with excellent elastic and piezoelectric properties, meaning that single grains have one polarity.
The small numbers aside of the points are the film thickness in micro meters (ref [27] and citations therein).
