Data for the nanopowders characteristics, as well as output rate and energy consumption are discussed in this paper.
Other consequence of the DPM mode is reduction of the output rate because of the roughness of the target surface.
Therefore, reduction of the on-off time ratio leads to reduction of average laser power and plainly output rate.
That leads to increasing of laser intensity in focal spot, reducing of thickness of melted material, and reduction of the energy wasted for thermal conduction.
Ability of shortening the laser pulse is limited by fore and back fronts of the pulse and reduction of laser pulse energy.

As a function of the exponent of the number of cycles, N, a linear reduction in residual stress was proposed by Han et al. [5] based on experimental data as follows:
(1)
where is the residual stress relaxation, is the residual stress at the first cycle and k is dependent on material softening and applied stress.
The proposed equations were validated against experimental data.
The values of these constants gathered from fitting the experimental data are shown in Table 2.
Eq. 7 is evidently able to account for the cold work effects and produces agrees well with the experimental data.
The estimation was found to be in good agreement with the experimental data from [7].

Then the data were analyzed using statistic methods, ANOVA, and Duncan’s Multiple Range Test (DMRT).
Seeing the data should have implication the highest calorific value and final heating temperature of AA among all samples.
The trend of methane reduction is the same as carbon dioxide reduction.
The lowest methane reduction implies the highest calorific value and final heating temperature although AZ3 showed the lowest carbon dioxide reduction.
It was caused by a decrease in carbon dioxide also accompanied by methane reduction.

Abstract
A nanosized cobalt-based alloy containing 20 wt % Fe was synthesis by electroless chemical
reduction method using alkaline tartarate bath and sodium hypophosphite as a reducing agent .
In particular, granular materials consisting of nanosized cluster soft magnetic metal embedded in a non-magnetic metallic matrix have potential applications as media for data storage.
From the phosphorus content determinations by spectrophotometry of the investigated powder was 2.5 wt% from the total alloy content meaning that the alkaline tartarate bath giving an electroless precipitate has low phosphorus content but by sintering in hydrogen atmosphere the phosphrous content decreased into 0.1 % due to the reduction of the metal phosphides to the phosogen gas which was liberated.

The data that are to be updated must be written to empty page of flash memory and then the original page of the data is marked as invalid.
FTL can maintain a consistent state for general data and meta-data, even though flash memory encounters an unexpected power-outage.
If erasure time of a block reach the threshold, data in the block is exchanged with the data in the block of the least erasure time in SSD.
In Li-ping Chang’s[9] algorithm, all blocks of SSD are divided into hot pool and cold pool to store hot data and cold data respectively.
Otherwise, data in the selected block will be swapped with data in the block that erasure time is least in SSD.

The formation of some reducing agents in the heat-treatment process should be responsible for
the reduction from Eu
3+ to Eu
2+ ions.
Introduction In recent year, persistent spectral hole burning (PSHB) has been paid to considerable attention because of its potential application in high-density optical data storage using the spectra holes [1-6].
These holes allow frequency-domain data storage, so that storage density increased considerably by an optical multiplicity which roughly equals to the ratio of the inhomogeneous line width to the homogeneous line width [4].
However, PSHB materials pose some problems for the practical application in optical data storage.
These formed reducing agents leaded to the reduction from Eu 3+ to Eu 2+ ions.

The data presented indicate that the type and concentration of the dopant have different effects on such parameters of a given semiconductor photocatalyst, such as the optical bandgap, absorption in the intrinsic area, and photocatalytic activity.
Data were collected over a 2θ angle range from 10 to 80 degrees with 0.016 ° increments and 1 second accumulation time.
The study of pure strontium bismuthate showed that it has a band gap Eg = 3.21 eV, which is in good agreement with the previously obtained data [20,21,26].
The introduction of lanthanum as a dopant manifests itself in the following ways: its low concentrations (up to 0.002) do not affect Eg, while the introduction of La in large amounts is accompanied by a decrease in Eg to 3.05 eV, which also agrees with the data [20].

Therefore, the numerator of Eq. (17) can be construed as cost reduction amount of Business E after integration, while the denominator can be construed as cost reduction amount of Business Q development after integration; in other words, when is a fixed value, the cost reduction amount of Business Q after integration is higher than that of Business E and the real estate enterprise will be more willing to integrate and attach more importance to integration of planning and design businesses.
The right side of Eq. (21) can be construed as the ratio of the product optimization degree 1 () subtracted by profit reduction amount of Business E after integration over the sum of cost reduction amounts of E and Q.
It indicates that for the same value, if the real estate sector obtains great cost reduction of other development business after integration at a cost of part of Business E’s profit, then the real estate sector needs to be integrated.
Calculation example Suppose that there is one real estate project with a total investment mount of RMB 800 million Yuan, the object of integration analysis is its construction business, while the other business is Business Q, we have =45%, =6%, =15% and =5%, =8%, based on statistic data.
