Both the samples had the same average grain size of 1-2 μm.

Microstructural analysis is done using high resolution optical microscope Fig. 1 shows the microstructure of normalized specimen showing small grains of proeutectoid phases.
Continuous spheroidization above the optimum duration may coarsen the pro eutectoid phases by dissolving some of its phases so that the number of pro eutectoid phases decrease.
The unit is VHN (Vicker’s hardness number) or VPN (Vicker’s pyramid number).

Table 1 Compression strength and slump of carbon fiber-reinforced concretes The number of concrete Compression strength /MPa Slump (cm) Mean value standard deviation A 48.7 0.23 2 B 49.1 2.66 3 C 49.2 3.25 2 D 52.2 1.01 1.5 E 50.1 2.61 1 Analysis of breaking strength In fiber reinforced concrete, because the fiber will absorb the energy released when concrete crack and increase the energy needed to fracture, the adding of fiber would enhance the breaking performance of reinforced concrete.
Table 2 Bending strength and tensile strength of carbon fiber-reinforced concretes The number of concrete Bending strength /MPa tensile strength /MPa A 4.4 2.2 B 5.1 2.6 C 5.5 2.9 Can be seen from table 2 that the bending strength increased 15.9% and 25% respectively and the tensile strength increased 18.2% and 31.9% respectively with the increasing of carbon fiber dosage.
When adding fiber into the concrete, fiber evenly distributed in concrete and improved the microcosmic structure, which make the concrete more close-grained.
Know from figure 4, the cracking-resistance property of carbon fiber reinforced concrete is greatly enhanced compare to ordinary concrete and the average cracking area and number of crack and total cracking area reduces 38%, 55% and 72% respectively.

The specimens was broken at number of cycles of 630442.
The Betti numbers are one of the invariant in a homology.
In 2-dimensional case, the Betti numbers are consisting of two numbers.
The other is b1= H1(X), which is the number of holes.
Because the Betti numbers are invariant, the shape of the grain has nothing to do with the Betti numbers.

Firstly, failure models of survivable system were formally described based on stochastic Petri nets, in which a number of measurable index parameters for recoverment were also given out.
(4) MTBF-(Mean Time between Faults) Mean time between faults, MTBF is approximately equal to the ratio between the normal service time and the number of failures, that is MTBF= (7) Recoverment Strategy for Survivable System Emergency recoverment is a technology of preventive and proactive survivability enhancement.
The survivability evolvement process Conclusions In order to make a reasonable fine-grained emergency recovery strategy of the survivable system, this paper presented a autonomous recoverment strategy of the survivable system, which made use of SPNs to formally describe the implementation process of the recursive reboot recovery.

If the n relation goes to infinity than he trajectory of possible realizations is the curve with number 8.
If the shape parameters are equal, there is the graph with number 1.
This area is located above the graph with the number 1 that is built when the shape parameters are equal.

Number simulation is a good way to predict the consequent of dust explosion, but the known of reaction kinetics of hazardous materials is necessary.

Based on analyzing and experimenting a large number of the existing fingerprint image preprocessing algorithm, this paper presents a novel high-quality fingerprint image preprocessing algorithm.
Based on analyzing and experimenting a large number of the existing fingerprint image preprocessing algorithm, this paper presents a novel high-quality fingerprint image preprocessing algorithm.
Based on making full use of the thought that fingerprint ridge along and vertical flow of grey level variance size are obviously different, this method uses the variance calculation of typical block size across 1 ~ 2 grain line distance.

Thus the total number of packet arriving at switch buffer is N* min(W, C* T1/L) in this time interval, where N is number of data server.
The number of short TCP working at same time is 20 and K=2.
According to Ref [2], the median number of concurrent large flows is 1, and the 75th percentile is 2.Thus we set the number of long live TCP to be 3.
We vary the number of data server from 40 to 160 with step 20.

Fractographic examination showed the presence of striations in Paris domain and secondary cracks at grain boundaries.
In fatigue tests, we note the crack length (mm) versus number of cycles N (a=f(N)).
At R=0.5, the fatigue life is affected by the amplitude of loading, where a decrease in number of cycles is significant [20].
