The test also provided the data to quantitatively assessment the positive effect of steel protective pipe for RC pile.
Fig.5 Finite element model scheme Fig.6 RC pile and ST pile fiber element sections Park-Ang double parameters damage index considered the effect of maximum deformation and cumulative hysteretic consumption for structural damage and this damage index has a larger number of test data calibration[2,3], so this article introduces modified Park-Ang model to simulate component of mechanical behavior in soften segment.

When aging treatments continued the regularization of γ' resulted in the improvement of stress-rupture life and the reduction of tensile elongation.
Each measured value is the average of at least 3 data obtained from 3 specimens.
When the cooling gas pressure raises further and cooling manner changes from static cooling to forced cooling, improvement of high temperature stress-rupture property and reduction of room temperature elongation ratio with increasing cooling rate take place.
By comparison of data in Fig. 7 and Fig. 8, it is easy to find that room temperature tensile strength and high temperature stress-rupture life of flat specimens are lower than those of cylindrical specimens.
As a result, the improvement of stress-rupture life and reduction of elongation ratio after aging treatment are predictable.

Since Co is a 3d fast diffuser transition metal, its introduction in the production line creates a potential risk of cross contamination with possible subsequent yield reduction.
The literature datum of a cobalt-related electron trap [3] is also shown for a comparison, and it is observed that the peak E1 in Fig. 1 reasonably corresponds to the extrapolation of the data.
However, the emission rate data we obtained are very scattered, suggesting the presence of more levels, maybe a band of levels which we cannot correctly separate from the two main levels.
Finally, from an extrapolation of the SPV response a practical LLD can be estimated from data plotted in Fig. 6.
This study has highlighted the strong reduction in Ldiff caused by Cobalt contamination that can be observed on both p-type and ntype silicon wafers.

So this paper, based on the relevant statistical yearbook data, will systematically evaluate the new pattern of Heilongjiang province’s manufacturing industry from three dimensions, including economy, technology, and environment, respectively.
Factor analysis is a multivariate analysis, a statistical method of dealing with dimensionality reduction.
After identifying the research methods, SPSS16.0 is used in factor analysis of the collected data.
The related data of the manufacturing sector in Heilongjiang province from 2007-2011 is analyzed using the factor analysis method.
When all data were considered, the contribution rate of accumulative total of variance of three factors in Table 8 is 98.283%.

The above contents show that the study on heat transfer and pressure drop for fluid in spiral coil mainly focused on numerical simulation, the experimental study of this problem is very limited and very few experimental data was obtained.
In this paper, the experimental study on heat transfer and pressure drop characteristics for water flowing in different spiral coil heat exchanger was conducted, and many heat transfer and pressure drop data were obtained, this can provide reference for optimization design of spiral tube heat exchanger, and has certain guiding significance for energy-saving operation of the air conditioning, heat pump system.
T1, T2—the water temperatures at the test tube inlet and outlet; T3, T4—the wall temperatures at the test tube inlet and outlet; P—the water pressure at the test tube inlet; ΔP—the water pressure drop through spiral coil 1, 2—valve; 3—steady head tank; 4—float flow meter; 5—pump; 6—DC source; 7—power meter; 8—voltage regulator; 9—spiral coil heat exchanger; 10—insulation layer Fig. 1 Schematic diagram of the experimental facility (a) ellipse spiral coil (b) circular spiral coil Fig. 2 Characteristic geometrical parameters of spiral coil Table 1 Details of spiral coils used in test section（mm） Spiral coil shape Type Outer diameter Inner diameter A B C D Ellipse SE 16 14 533 220 80 52 BE 16 14 593 220 80 52 Circular SC 16 14 200 - 122 97 BC 16 14 295 - 116 89 Data Reduction The heating power in test section can be obtained by the power meter in circuit, because the test section was wrapped by rubber
(2) where the coefficient C and the exponent a can be obtained by fitting the experimental data.
Data Reduction The influence of Re on Nu is investigated.

Having these data the procedure is simple.
By defining the confidence interval of the data at given percentiles, the requirement can be defined so that a given percentage of buildings – e.g. 90% – will fulfil it.
Certainly the collection of data for a thorough statistical evaluation would be very time consuming, the sample is to be randomly generated instead.
Selecting a huge sample from the existing building stock does not guarantee that the statistical evaluation will be reliable, not mentioning the time-consuming data collection.
The detailed data of the components of the energy need show that if we have a high quality building envelope and mechanical ventilation with heat recovery, the domestic hot water supply becomes the key issue.

Transformer Design and Experiment Data There is a RCT, whose core is made of a ultrachrystallite material, shown in Fig. 5 with an outer diameter D1, internal diameter D2, height h0.
It can be seen from Fig. 6, in lower frequencies, the theoretical values better fit experimental data; as frequency increases, higher than 8 MHz, the experimental data gradually deviates from the theoretical value.
At higher frequencies of about 24 MHz, the theoretical value and the actual data come to a minimum value at the same time.
The 3 dB passbands of the theoretical values and experimental data overlap approximately.
Fig. 9 is the data of the RCT comparison experiment containing uniformly coil winded CT without shielding box, uniformly coil winded CT with the shield box and specially coil winded CT without shielding box .Through comparison: ① the CT with a shield box is significantly less impacted by the rise of frequency than the one without shield box.

The applicability of the second_order equation was proved by the linear dependence of the experimental data in the ln(1/θs–1/θ0)/T2–1/Т coordinates, where θ0 is the degree of the complete coverage of the surface.
The data in analog mode representation was obtained (MS plotted).
The decrease in intensity is connected with the reduction of copper oxides included in the catalyst.
DME desorbs in the temperature range 473-673 K (Тmax=553 К), which is also consistent with our data obtained in the catalytic experiments to determine the effect of temperature, which showed a maximal yield of DME at 553 K.
These data provide the basis to develop the technological standards to produce DME from CO and H2 combining two reactions in a single reactor.

From the test data, the regular curves of the shear strength discounting ratio were determined for the soft clay under different dynamic and static combinations.
Based on the experimental data and spot investigation, the numerical analysis model was built to analyze the stability of inland waterway slope under effect of ship wave.
The driving system is pneumatic, mainly consisting of the pneumatic power device, the testing machine, the data acquisition system and the computer.
Fig.1 The dynamic triaxial testing system, model for DCS This system equips with a patent dynamic ambient pressure balance device, which could really ensure the stability of the ambient pressure under the axial dynamic loading in a high frequency, and a real-time data acquisition and the man-machine dialogue system known as the software GDSLAB which is able to display and switch the real-time test data dynamically in the experiment.
Also, the slope stability before and after the action of ship wave were analyzed contrastively by strength reduction method.

The optimizing software tool is an important constituent of PRO2 TM, since it couples the models that are part of the process chain and organises the flow of data between individual models.
The arrows in the figure show the sequence of the through process simulations which are run in several iterations, where the optimiser tool selects the input data for each new simulation based on the results from the previous.
FE based casting programs [5]) or they can be based on experience data from measurements on similar alloys, as in the present work.
Input data.
Due to limitations in space, the paper was focusing on simulations without any verification of the output data.
