Generally, perovskite type proton conductors show mixed hole and oxygen ionic conduction in air at high temperature, and as temperature decreases, proton transference number increases.
Finally, its proton transference number becomes unity in the intermediate temperature region.

The reason is that it is a complex process, in which a number of parameters must be optimized.

We previously reported that the internal surface of SUS304 stainless steel tubes were
finished with MRF-based slurry that included WA abrasives, and that the finished surface was
smoother than a surface finished with the usual grain type of magnetic abrasives [4].
As the size of the diamond abrasives diminishes, the number of the diamond abrasives increases because the diamond abrasives are included at an abrasive/liquid ratio in MRF-based slurry.
Accordingly, there is not much difference in the numbers of diamond abrasives cutting the surface even given varying sizes of the diamond abrasives.

The above described observations of the fracture surfaces of the A-5YTZP and A-40YTZP samples
revealed the same kind of tendency as that previously observed on polished cross sections of these
samples [1,2]: the decrease in both the number and size of defects as pressure increases, reaching
defect sizes of the same order of characteristic microstructural defects (agglomerates of grains and
pores, ~30-50 µm).
However, the number of valid experiments was so low that a more detailed interpretation of the data is impossible.

Firstly, according to the predetermined number, lead acetate trihydrate and acetic acid were mixed in a ratio which was distilled at 110℃ for 30 min to remove water.
As the film thickness increased, the number and location of the peak did not change, but Raman peak became sharply and more and more obvious, strength is increasing, indicating that crystallization is getting better.
With the increase of film thickness, the remanent polarization increased from 19.7 to 37.7μC/cm2, but coercive field decreased from 72.42 to 41.2kV/cm.This is because that with the increase of the spin coating times, the film heat treatment time became longer, resulting in larger grain size and better ferroelectric performance.

A number of samples with different contact pads were investigated.
These phenomena were observed on a number of sensors with different contact pads, such as Au/Ti, Pt/Ti, and Pd/PdOx.
The PdOx layer (~100Å) did not provide a sufficient barrier for the platinum; the Pt diffuses through the PdOx grain boundaries and forms silicides causing a rough surface (Fig. 5b).

And then placed the digestion reaction tank in ultrasonic cell disrupter system, adjusted the ultrasonic working time 4s, interval 6s and total number of 60, started this instrument.
At the same time, mechanical shear would make latex grain surface electric double layer or hydration layer to be deformation.
As a result, the initial particle size increases with reducing the formation of number of elementary particles.

Kai Yang et. al have studied the principle of open source OSGi framework, the core specification and open source OSGi framework, who also design and implement a variety of OSGi framework for functional testing and performance testing; however, what they focus on is functionality and performance testing in different frameworks, which belongs to coarse-grained testing[4].
At the same time, test running area will trigger the extraction of the testing details in data collection module, such as the number of successful and failing use case, successes and failures information and error tracking information.
Finally, data collection module will call data management module to process a large number of extracted testing data, and data storage module will store them in the data storage area.
