Abstract.
Researchers have proposed on the basis of the theory of random field model, static sounding (CPT) according to the data calculated soil related distance, and then calculate the pile resistance statistical characteristic, finally calculate reliability index.

Due to the space limitation, the measurement result data within a period of time before and after starting the SRE suppression circuit are taken, and the distribution in the time domain is shown in Fig.4.

Fig.4 The measurement data in time domain distribution
4.4 Experiment data analysis
4.4.1 Time domain analysis
The experimental data in time domain distribution is shown in Fig.4.
The data before and after starting the SRE suppression circuit for about 8 minutes are intercepted for the data analysis.
In the analysis of the time domain data, it can be found that the ship alternating electric field intensity (1-7Hz) is about 2.86×10-4V/m before the startup of the SRE suppression circuit.
In the measurement electric field data after the startup of the SRE suppression circuit, the environment electric field accounts for a large proportion, and the environmental field is difficult to eliminate.
Although the experimental data in time domain display 1-7Hz alternating electric field strength from 2.86×10-4V/m down to 0.72×10-4V/m, approximately 75% reduction.

Ecological houses have become very popular lately due to an increasing concern regarding the reduction of the CO2 emissions generated by the building sector.
The data results acquisition showed in the graph were recorded using two digital instruments Spider type.
The measured data is collected by Datalogger device and is transmitted to the Loggernet software running on a desktop, which processes the data numerically and graphically.
The program also gives a graphic interpretation of the measured data, i.e. temperature differences (DT) and heat flows (HF).
Data obtained from the software „Loggernet” must be further processed to obtain the parameters needed for the thermal characterization of materials, i.e. thermal resistance R, thermal transmittance U and thermal conductivity λ.

The fatigue test data of the HTGN specimens are also plotted in the figure.
The S-N curves in 3%NaCl solution are represented in Fig.5, together with the data in laboratory air.
In addition, fatigue failure occurred at applied stresses below the fatigue limits in laboratory air, indicating the reduction of fatigue strength in the corrosive environment.
