frequency range at temperatures from 450 to 750°C.
The oxygen reduction reaction occurring at the first PtAu electrode can be written, in analogy with a Pt/YSZ interface, as: ½ O2(gas) + 2e -(electrode) → O 2(electrolyte) where gas is the oxygen source, platinum electrode acts as electron reservoir, and YSZ is an ionic conductor.

After examining the urban planning model and marine pollution data of coastal cities in China, two typical urban planning model which named “bay-oriented model” and “mainland-island model” are faced with challenges of ecological degradation.
Table 1 Examples of the ecological effects of island development in coastal cities Island link projects Ecological effects Wenzhou Damen bridge linking Yueqing and Xiaomen island Under the influence of bridge main piers, relative intensive approach spans and bearing platform piers, flow section relatively decreased causing tides slightly reduction Jintang bridge linking zhenhai Ningbo and jintang island in Zhoushan Scour range became larger adding to erosion around the area of piers Changdao dam linking islands The velocity of seawater flow reduced leading to sediment deposition near the dam Improvement Measure of Coastal Cities’ Human Settlements Ocean development triggered a profound impact on the ecological effects of coastal cities’ human settlements.

On the basis of the obtained data, approaches and criteria for obtaining compositions of low-melting chalcogenide and oxide glasses with practically useful properties are formulated.
The first results on the reduction of crystallization of glassy (amorphous) chalcogenides were obtained in the 60s of the XX century in the study of S and Se with the addition of p-elements of the type As and Ge.
According to the data of IR absorption spectroscopy, the intensity of the absorption bands corresponding to the vibrations of the GeBr2S2/2 structural units depends on the conditions for the synthesis and tempering of glasses, which indicates the instability of the corresponding compound at high temperatures.
Wave numbers of bands 1 – 150 cm-1, 2 – 235 cm -1, 3 – 256 cm -1, 4 – 286 cm -1, 5 – 345 cm -1 According to the data of IR spectroscopy, the three-component interaction is also characteristic for glasses of the (GeSe2)1-x(GeBr4)x system, as well as for glasses (GeS2)1-X(GeBr4)X.

The mean absolute relative residual (MARR) is reported as a measure of the precision of the fit:

Where n is the number of included data points.

We declare that each experiment was replicated three times in order to verify the experimental data accuracy and reproducibility.
For evaluation of size-dependent parameters in developed kinetic model (equation 12), the experimental data is fitted to the model with a non-linear optimization routine.
The model parameters have been calculated from the experimental data (Table 2) by minimizing the mean absolute relative residual (MARR) (equation 13).
Size dependent kinetic expressions were derived and evaluated using experimental data of catalytic activity versus the average particle radius of nanostructured iron catalysts.

Although PCA normalizes the original data, there is still a problem that it does not reflect all the information in the data set.
Almost all data sets have a certain degree of error, and the data sets used in this study are no exception.
In spite of the data cleaning required in the project, it must be stated that there are still incorrect values in these data sets.
Therefore, the data were used to identify trends, but there is no guarantee that any one single data value is completely correct.
The data set includes 73 high yield wells and 156 low yield wells.

Because electricity is the most grade energy, the equivalent electricity methods were adopted [8, 9] to transform gas and hot water into equivalent electricity (kWh), and gained the total energy consumption by converting, in which the reduction coefficient of the fuel gas and hot water is 7.313 and 0.06435 respectively.
