The calculated data were compared with experimental results.
We have chosen the solid solution Ba(Ti,Sn)O3 (BTS) since its piezoelectric coefficients reach at least 30 - 40 % of the PZT data.
Furthermore, a non-zero electrical conductivity σk was included, which was significant for the description of the experi-mental data.
Fig. 7a shows the comparison between the measured electric fields during the poling of a bimorph sample and the data fitted in the framework of the model described above.
The satisfying coincidence between experimental and fitted data indicates the suitability of the poling model.

Results and Discussions
In this section, some typical data are chosen to discuss.
In this case, data processing is only averaging three curves.
The rest data are partly consistent, as shown in Fig2 (b).
In this case, before data processing the third curve should be deleted.
Viewing from the all data, it can draw a conclusion that the test result of NMR relaxation time is reliable and stable.

That 20 year lifetime goal is itself a reduction from the earlier 30 year lifetime design goal [6].
Combining analysis results with experimental data and engineering know-how lead to higher efficiencies and improved product reliability.
Data from its validated models can be used to analyze the interaction of bearings and rotating elements within a turbine’s housing.
It also exports design-specific bearing data back to system models, so modifications and trade-offs can be made as needed.

The microbial ferrous oxidation rate at each dilution rate was determined
from the knowledge of O2, CO2 utilisation rates using the degree-of-reduction balance [14] and also
from a ferrous iron mass balance over the reactor.
Also included are the data from a previous study with the same total iron concentrations, but all with only ferrous and no ferric in the feed [1, 3].
Analysis of the present data, given in Table 1 shows that the maintenance coefficient is small or negative, which is consistent with actively growing continuous culture which is not substrate limited and where there no wall growth, as shown in previous studies [1, 3].
It can also be seen, from both Figure 3 and Table 1, that the yield data does not follow a strictly linear trend, since the value of the yield coefficient max2 XFeY + is not strictly a constant, but itself a function of DrFe +2 or of total iron concentration.

Based on research of index system of evaluation on ecological cities of China currently, Chinese
scholars have problems in research of index system of evaluation on ecological cities such as
over-sized designed index system, much difficulty in index quantification, weight allocation and data
acquisition and low compatibility of index.
Thus, this article, based on sample of data of Ha'erbin between 2002 and 2008, carries out calculation with SPSS statistics software so as to get weight, characteristic vector and scores of principal components of each sub-system to conduct quantitative evaluation on construction of ecological city of Ha'erbin.
Evaluation on construction of each sub-system of ecological system of Ha'erbin (1) Standardization of original data and analysis of relevance of data.
