Introduction Sn2P2S6 family ferroelectric crystals, which undergo a phase transition with symmetry reduction from 2/m to m are particularly interesting both from applied and fundamental physics in relation to their semiconducting, ferroelectric and piezoelectric properties.
There are no data on ultrasonic properties in (Sn,Pb)2P2S6 system.
It was confirmed using our measurements for ferroelectric phase using data from Fig. 2 after calculations of = f(T).
The polarisation relaxation time estimated from our attenuation data was τ ~10-10/(TC-T) s.
The polarisation relaxation time estimated from our attenuation data was τ ~ 6·10-9/(TC-T) s.

Data analysis of experimental diagram shows a descending tendency as grinding is longer with some exceptions.
Data analysis of grinding results shows a descending trend as grinding is longer (from 2 to 4 min).
Data analysis represents increasing tendency of sand/cement ratio as compressive strength is lower.
Some conclusions can be done by analyzing the data obtained from the mixtures I and IV.

They also pointed out that N2O post oxidation annealing (POA) leads to a 40% reduction of charges with fast de-trapping time constant (<10s) with respect to Ar POA, leaving unchanged the density of slower traps located deeper inside the SiO2 layer [4].
In particular, the first VG sweep shows a “non-steady” (temperature dependent) behavior corresponding to a low hole barrier height (<2eV) if data are fitted with the standard FN model.
However, as shown in Fig. 2, the experimental data exhibit a transient of the gate current.
The experimental data were fitted using Eq. (3) (solid lines in Fig. 2) and the NITs density was determined as fit parameter (Ntrap=2×1011cm-2).
The fit of the experimental current transient data allowed to determine a density of near interface traps (NITs) in the order of 2×1011cm-2.

To realize the goal of energy-saving and emission-reduction and the goal of economic structure reform, series of policies have been released to encourage and promote the development of electric vehicle industry, not only on public transportation, but also on private electric vehicles.
They meter the actual discharged amount, and transmit the data to the on-board terminals.
And this imposes more demands to electric vehicle manufacturers to reserve enough spaces to accommodate ammeters and equip vehicles with terminals that can collect data from ammeters.
As to the battery exchanging mode, which takes minutes to replace battery, it cannot afford enough long time to acquire the metering data.
Therefore, it cannot spread before unified standards on installation, wiring, data collection and communications are issued and supported by all sorts of vehicle suppliers.

Introduction The application of renewable energy in buildings is one of six fields of energy-saving construction with maximum potential, and is the strategic core and advancing front of energy-saving and emission-reduction in construction.
Therefore the government attaches importance to actual operation effect of renewable energy application in buildings, and successively promulgates the Testing Guidance on Demonstration Projects with Renewable Energy Application in Buildings and the Technical Guidance on Data-monitoring System to Demonstration Projects with Renewable Energy Application in Buildings to guide the operation and acceptance of projects[1-3].
From the data of property management department, we can only get the power consumption per square meter during the heating supply.
For being short of data on total cooling and heating volume, the government authorities can not calculate the normal energy substitution correctly, and can not make corresponding policies according to the data.
