Fig. 6 shows the pixel array number dependency of Mn K fluorescence intensities of the three Fe-Mn alloy samples.
The number of detection pixel array was counted from the position at zero detection angle.
Therefore, the detection angle increases with increasing pixel array number.
As shown in Fig. 6(a), the fluorescence intensity distribution of the as-prepared sample increased monotonically with the number of pixel array (detection angle).
The roughness of the sample surfaces becomes larger with increasing the annealing temperature due to formation of manganese oxide and the grain growth at the surface.

Material and data Experiment material Vinegar: (a)Black Rice spicy vinegar, (b) Jiajia mature vinegar, (c)Shuita mature vinegar, (d)Xiaoerhei grain spicy vinegar, (e)Zhenjiang spicy vinegar, they are bought from Yangling Guomao Supermarket.
Since the sampling interval is 0.5nm, a vinegar sample is a 171-dimension vector, and there are only 7 samples for one kind of vinegar, the dimension of sample vectors is much larger than the number of samples, this is a typical small sample problem.

These applications require an optimization of chemical composition, the shape and the grain size of NPs [6] .Recently, a new method was developed to synthesis metallic colloid by using pulsed laser ablation in a liquid solution.
This decrease can be attributed to the aggregates fragmentation, and also when the laser fluence increases the ablation efficiency and the number of particle increase.

The rationale was that the grain size of fluorgypsum was gradually refined through nobbing or fragmentation in the grinding process, which could increase of particles specific surface area.
Through a large number of systematic experimental study, an effective compound activator was determined, and its main composition was sulfate and carbonate.

On the contrary, the smaller gate size of die-casting mold, the lager the Reynolds numbers is, and this cause the decline of the density and deteriorate of mechanical properties to the standard sample.
The primary solid phase of the sample with large gate sectional area are more than that of small gate sectional area, and the grains are accompanied by many tiny spherical crystal in two specimens.

When the temperature was continued up to T5°C (e) and T6°C (f), the number of the lath bainites was clearly increased, and the dimension of which was finer.
As quenching temperature increased from T3°C to T6°C, the volume fraction of lath bainites was gradually increased and the size of the grains became finer.

The nature of the admixture also influences the kinetics of the contact melting, especially in cases where there is an electric potential: alkali earth admixtures create 30% less contact interlayers by length in comparison to the regular In admixture; this may be explained by a possible internal contact melting in the Bi-In system, where indium gathers along the grain boundaries, thus facilitating transition of the boundary zones of bismuth to the liquid state.
