The crystallites are composed of smaller polycrystalline grains; grain boundaries are amorphous, once they are brought to a high enough temperature they melt.
Again, in bulk form of Hummers method grown GO samples, the structure, surface, orientation and number of the layers have shown a close relation with the graphene content, functional group composition, preparation conditions and further purification (eg, centrifugation [20]) of the synthesized samples [21].
A number of the layers was calculated from the ratios of G, D and 2D band peak intensities ID/IG and IG /I2D.

With the increase of solution temperature, the number and size of secondary α phase increase significantly.
When the solution temperature increased from 980 ℃ to 1000 ℃, the grain boundary between primary α phase and β transformation structure decreased, and the resistance to dislocation slip decreased, which leads to the increase of plasticity.
The alloy heat-treated at 960 ℃/1 h/AC +650 ℃/6 h/AC had a large number of dimples, the depths of the dimples were deeper, but the sizes were uneven.
After 980 ℃/1 h/ AC +650 ℃/6 h/AC heat treatment, the alloy’s dimples were less in number, shallower in depth, and unevenly distributed, so the plasticity was the worst.
At the same time, the number of secondary α phase rises and the size augments. 3) Heat treatment can effectively improve the mechanical properties of the alloy at room temperature and high temperature.

the coordination of ecological conditions of gas hot water in the soil, to create a good soil environment for root growth[8]; Fengyu Li studies show that: straw returned can reduce soil bulk density, increase soil porosity, improve soil structure, increase the soil available nutrients[9].(2)Straw returning could significantly increase crop yield.Wentao Lu comprehensive test results from the four years of straw returned, short term and amount of straw counters-field effect on crop yield significantly, but returning from a long cycle, high amount of straw returned have more advantages on crop production[6];Weihong Sun research results show that the straw returned to significantly increase crop yield, in loam increase production effect is better than sandy loam[8];Li Gu through long-term and short-term comparison of controlled trials showed that the straw returned with stimulation effect[10]Returning Caixia Zhao research results show that Returning all is beneficial to the increase of grain
yield[11];Feng Miao the experimental study shows that under the condition of no nitrogen, straw returned increase the summer corn grain yield significantly[12].(3)Straw returning can increase soil organic matter.Zhigang Dai straw returned test showed that different cultivation mode can increase the soil total organic carbon and organic carbon oxidation state, and increased the activity of soil organic matter[7];Fengbo Li research shows that the straw returned significantly increased soil organic matter content, total nitrogen and available phosphorus content, to increase soil organic matter and available potassium content has obvious promoting effect[13];Xunhao Liu etc.
The research of straw stock raising Straw due is the best reward to use conventional technology, adopt scientific breeding methods, make full use of natural resources and the natural conditions, with a relatively low investment, produce high quality beef and mutton, wool, cashmere, etc[18].Moreover, cattle and sheep manure can be used as farmland fertilizer, so that the soil is fertile and grain production, and produce a large number of straw, and form a virtuous circle.At the same time, straw stock raising, saving a large amount of feed grain use; That can reduce pollution of the environment; Is beneficial to improve people's food structure[19,20].Returning straw livestock reared GuoFu, also can effectively stop the happening of the mad cow disease[18].It is important to note that the use of straw due to raise cattle and sheep for ruminants[21].Yongge Gao study showed that straw due to promote the "big development" of plant-eating livestock such as cattle and sheep, and drive the slaughtering

The formation of deoxynivalenol and fusarium graminearum can be reduced in wheat grains by ZnO NPs without any damage to grain structure [10].
It was also reported that the application of ZnSO4 and ZnO NPs increased the Zn content in grains of wheat but within the grain ZnO NPs were not detected [18].
Significant findings were reported by the application of ZnO NPs on various crop plants in terms of germination of seed, growth of the seedling, contents of total sugar, protein and nitrogen, biomass, improvements in micronutrients and efficiency of photosynthesis in the number of crop plants like tomato, cucumber, spinach, mung and wheat [16, 17].

Elastic deformation will be able to resume after that the load is recovered, with the number of loads accumulated gradually, the plastic deformation will increase.
Specifically, such as the need for static triaxial test, the need for dynamic triaxial repeated load test and the need of the load number.
However, the more convenient use of the model parameters including the number of more complex patterns, and the establishment of model tests carried out more.
Therefore, the stress is not only used to determine the number of parameters.

SiC epi-layer grown above these terminated micropipes is continuous without any twins and grain boundaries.
Finally we can say that Ti is one of the most promising solvents since it realizes stable solution growth without formation of crucial number of defects.

A number of surface technologies have been developed for improving properties of aluminum and its alloys including anodic oxidation, PVD, and micro-arc oxidation (MAO).
As it will be shown in the more microcosmic observation, a cluster is composed of smaller grains 50-80 nm in size.
