All of the peaks can be attributed to the PZT, according the JCPDS number 33-784.
It can be seen that distribution of the grains is rather even.
The average grain size is about 0.8 mm.

A further surface SEM observation exhibits that the crystal grain of the film is in the range of 50-100nm.
So the grains in every column are regularly oriented, resulting in crystallographic texture of the film at last. 30 40 50 60 70 80 0 5000 10000 15000 20000 25000 30000 (331) (222) (400) (311) (220) (111) Incidence angle=45 ο Incidence angle=30 ο 2theta(deg.)
It is defined as: 1 . 1 hkl hkl hkl rhkl rhkl I II n I ω = ∑ where Ihkl is the diffraction intensity of (hkl) plane in preferred orientation specimen, Irhkl is the diffraction intensity in random orientation specimen, and n is the number of diffraction peaks.

The numbers on the red lines are the energies relative to reactants in kcal∙mol-1 Chemical reaction rate.
Coarse grains doped with fine grains had secondary nucleation in the diamond growth because that was promoted by a large amount of hydrogen ions in the reaction chamber at a lower temperature.

The corrosion process of eutectic structure can be described like this: molten zinc enters into the matrix along the grain boundary, then corrodes the α phase first, however, Fe2B phase is seldom corroded for its non-wetting with liquid zinc.
According to the model the corrosion process can be divided into such steps as follows: molten zinc absorbed by matrix and Zn atoms diffuse inward the matrix along the grain boundary→molten zinc corrodes first precipitates α phase immediately→network eutectic structure loses its supportings of first precipitates α phase and spalls off→molten zinc contacts with the α phase again.

SEM examination of the carbide tools used to machine nickel-base alloys has shown a layer of 'distributed' material beneath the crater and the cutting edge [5]; in this layer the tungsten carbide grains being smaller and more rounded than in the original material.
These designs allow efficient estimation of the first and second -order coefficients because Box-Behnken design has fewer design points, they are less expensive to run than central composite designs with the same number of factors.
Heat and pressure generated by machining can cause the cutting tool's binder to soften, allowing the carbide grains to move.

Two linear fibers, possessing a diameter of approximately 60 nm, emanate from a central nickel nanoparticle with a grain size of circa 60 nm.
The fiber diameter is almost the same as the grain size of the nickel nanoparticle.
The two helical nanofibers are identical in coil diameter, coil length, fiber diameter, cycle number, coil pitch and cross section.

Because ultrafine ceria grains were easily condensed into clusters, low concentration of abrasives is preferable to Fig. 9 Photographs of burned wheel (type D) and wafer 0 30 60 90 120 150 180 Type A Type B Type C Type D CMG wheels Dressing interval [min] Fig. 7 Typical wafer surface topography after Fig. 8 Effects of wheel types on CMG using Type A wheel (Ra: 0.7nm) dressing interval prevent ceria abrasives from conglomeration.
Fig. 10 SEM image of type B wheel Fig. 11 SEM image of type D wheel With ceria concentration increasing, the number of the effective ceria abrasives (abrasives exposed or released from the CMG wheel) in CMG process did not increased or at least did not increased sharply due to poor self-dressing ability.
(2) The additive of sodium carbonate could effectively weaken the adhesion between ceria grain and bond, resulting in good self-dressing ability to facilitate the chemical reaction between Si material and ceria during CMG process

According to investigations by previous researchers, these oxides are attached to the boundaries of large grains or they are present as small grains [14,15].
This result is quite satisfactory since the increasing number of sodium titanate formed as an intermediate phase is highly expected.

HZ8 The high tolenrance (4.0 mmol·L-1Pb, 5.0mmol·L-1 Zn) HZ9 Intolerance A group of same grain size and well-developed seeds of Trifolium repens and Crotalaria mucronats were carefully selcted.Firstly,disinfecting them with 75% alcohol for 30 s,and then with 0.1% HgCl2 for 3 min,washing them with distilled water for three times.The seeds were put into the Petri dish in which were added the mother liquor dose, which is 0.1 g•L-1 of ZnSO4•7H2O,and Pb (C2H3O2)•3H2O in order to design the media which contains different lead-zinc concentrations.The concentration is shown in Table 2.One hundred grain of seeds were put in the different Petri dishes respectively and cultured in the incubator with 23-25 ˚C.Each treatment was done 3 times.The germination of seeds were determinated after three days.
Each treatment was done 3 replications.The root length,stem height, chlorophyll content, nodule numbers, nodule nitrogenase activity rates and other relevant datas of seedlings were determinated after 45 days.

On the one hand, it is related with the roughness and crystal grain size of the friction surface.
The NiCrAlY coating was smooth and its crystal grain was smaller than the substrate.
In the early stage of oxidation, a large number of oxide nuclei rapidly coalesced to form a thin oxide layer.
