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 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.

Emergy is energy number transformed from another type energy containing flowing or storage (Odum, 1988[7]).
Ecological capacity supply (EC) shows the sum of ecological productive land area that it can provide the human of the region, which is the total emergy of renewable natural resources of the locality divided by the region emergy density (D): EC= ER/D (4) Renewable natural resources of Jiaxing main includes rice, wheat, barley, corn and other grain, beans, potato, rapeseed, cotton, hemp, sugar, melons vegetables, fruits, edible vegetable oil and silk.
We can have the per capita ecological footprint (ef), the per capita ecological carrying capacity (ec) and the per capita ecological surplus (es) though EF, EC and ES divided by the total number of region population (P), respectively.

Aluminum alloy grain caused by organization change in volume change can also cause the deformation of the weldment is this wooden reasons for welding stress and deformation.
Second, weld number to clear the influence of welding deformation, weld is less, the better for welding deformation, this requires the design as far as possible under the condition of meet the requirements, optimize the weld number, avoid unnecessary weld, so as to control the welding deformation.

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.
