Market competition of electronic products is extremely fierce, and market cycle of products is getting much shorter, which at the same time requires the significant reduction of electronic products' design and development cycle.
Diagram of Overall Structure The system consists of client layer, intermediate layer and data layer, as is shown in Fig 1.
Data layer: data layer is to become the medium of computer information storage through relational database.
After the user sets up a 3D experiment scene according to the existing components in the experiment, tools automatically hand over the generated experimental data to the simulation solution module for results calculation and at the same time conduct the visualized output on the returned simulation results according to the requirements of 3D virtual experiment.
The interfaces among all the modules follow unified specifications, such as framework standard of 3D virtual experiment, terminology standard, component metadata standard, component package standard, service interface standard, process control specification and data exchange specification.

Results and discussion The minimum-energy configurations of pure anatase TiO2 obtained by GGA and GGA+U methods in our study were compared with experimental data [14] as shown in Table 1.
It showed that the agreement between GGA method results and experiment data is better for the structural parameters than ones of GGA+U method.
For Ce-doped TiO2, Fig. 2b shows that the VBM consists mainly of O 2p and Ce 4f states, whereas the CBM has Ti 3d and Ce 4f states, the impurity states change the construction of band, and thus led to a band gap reduction by about 0.29 eV, which would be expected to lead to but a little enhancement in photocatalytic efficiency.

These data allow not only the comparison of this specific PPO with similar enzymes from other sources but also contribute to the clarification of the mechanism, with significant implications for browning inhibition.
Each data point was the mean of three determinations.
The data were recorded in the figure 2 as follows.
Conclusions The above experiment data showed that the optimum temperature of PPO from PSP was 16℃ with the second optimum temperature at 30℃.
Collectively, the data indicate that high-temperature blanching and low-temperature storage are necessary methods to control the enzymatic browning caused by PPO in PSP.

Key applications of SECM have been demonstrated based on the newest literature data covering the past two years of the active research in the field of corrosion in a nanoscale.
Data collected from the Science Direct.
Basic operational modes of the SECM: a) disc microelectrode tip positioned in the bulk solution (distance of tip from substrate: d = ∞) where the steady state tip current (iT) for the reduction of O into R is totally diffusion controlled, b) the positive feedback mode at a conductive substrate which regenerates O from R, c) the negative feedback mode based on hindered diffusion of O by an insulating substrate, d) substrate generation/tip collection (SG/TC) mode, e) tip generation/substrate collection (TG/SC) mode [36].
The investigators also observed that some anodic peaks were succeeded immediately by cathodic peaks, and that both the oxidation and the reduction reactions proceeded simultaneously at local pitting sites on Ti surface.

The calculation results can reflect the dependent degree of the study area on external water resources, but detailed import and export trade volume data is needed.
Despite the trade volume data is difficult to obtain, it can be estimated by the multi-regional input-output method (MRIO).
Moreover, without the need for inter-regional product flow data of sub-regional and sub-sector, the impact of production technology and trade patterns on virtual water can also be distinguished [13]
The calculation results can reflect the impact of the consumption structure on the water footprint, but detailed consumption data is needed.
However, due to China lack of long-term serial trade and consumption data from different products by regions, both methods have been restricted to some extent in practical applications.

Methodology Data Preprocessing Nucleic acid sequences are various in size and length.
This method adopts the use of majority voting scheme, which employs the whole data set for generating references for all four Dengue serotypes.
In addition, the projected data explicitly reflects the true pattern of a Dengue virus sequence.
Finally, this method for projections can be adapted for future analysis, such as classifications, clustering, and association; for higher accuracy and availability of data inputs.

A kind of combination is generally believed that the use of Pb-Ca positive grid that the active material interface layer of the corrosion resistance of purified large insulating film.To prevent the generation of the purification, the general method is to add the Sn,that is, high Sn and low Ca alloy,so the alloys are used in the positive plate of poor water VRLA battery which the water loss is a minimum and its test data is 1.5-2.5g/Ah.but the mechanical strength,creep resistance and deep charge and discharge performance ( no effect in the presence of antimony) of Pb-Ca alloy is still below the Pb-Sb alloy.The small electric vehicle batteries use flooded design that it could regularly pay replenishment and maintenance,so Pb-Sb multi-alloy should be the best selection.B alloy is the best combination which can effectively improve performance while maintaining deep cycle relative reduction of water loss purposes.The alloy components are: Positive plate alloy : Pb+Sb(1.8-2%)+As(0.1-0.2)+Sn(
