With the increasing number of wells and improved quality of seismic data, oil and gas resources have been found in fault basins in recent years[8-9].
The steep slope zone mainly develops nearshore subaqueous fan characterized by coarse grain and random distribution.
Grain size is upward-fining.

A number of external influences — physical (e. g. low and high temperature), chemical, and mechanical — affect the structure during use [2-3].
After blasting, the grains of the aggregate were exposed.
The aggregate grains were intact and were tightly anchored in the cement putty (see Fig. 5).

Forging plays a role in homogenization and avoid coarsening of grain.
Forging plays a role in homogenization of grain size.

Powder and grain material conveying and weighing often uses the screw conveyor in rubber production, such as entity of helical blade, no hanging bearings, single head fixed horizontal screw conveyor of change pitch, shown in figure 1.

In the conveying process, cell body and helical blade can produce serious wear easily, so in manufacturing of screw conveyer should pay attention to the following points: The molding of helical blades: First, process a certain number of single blade according to the requirements of the drawing, then cut one side of blade and weld them in group.

As fatigue tests under the IP cycling, tensile stress occurs at high temperature, where the cohesive strength of the grain boundary is low, so the occurrence of negative mean stress is reasonable.
In all of these loading conditions, the crack mainly initiated at grain boundary and then propagates in a transgranular manner.

At low laser fluence the formation of C2 molecules is due to the collision of electrons with clusters of higher numbers of carbon atoms, whereas at higher fluence, excitation resulting from electron-ion and ion-ion recombination is responsible for C2 swan band emissions [12].
The film is crack free and grains are tightly packed.
The size of the irregular grains varies from 50 to 100 nm.

Although, a number of papers [1-9] are dealing with the methods of determination of size and shape of plastic zone, many questions regarding its internal structure, shape and ways of evolution, still require attention.
The distances from these places to the microcrack tips were measured, and subsequently the polished surfaces were chemically etched in order to reveal austenite grains.
Moreover, taking into account all the above, the shape of plastic zone will alter depending on crystallography (slip and twinning) of the considered area of grain; mainly in polycrystalline materials.

The major technical measures of construction were as follows: (1)Axis, elevation, reinforced, templates, steel strand, position and number of the preformed hole must be checked
The same strength grade mortar which have a little stone were poured 0.02m thick in the meet Cha of the wall so as to ensure the meet Cha close-grained compacted.
Mechanical vibration was used of in the construction to ensure the concrete close-grained.

The enhanced hydriding kinetics is principally ascribed to the refined grains by melt spinning.
The huge number of interfaces and grain boundaries available in the nanocrystalline materials provide easy pathways for hydrogen diffusion and accelerate the hydrogen absorbing/desorbing process [4].

From the FESEM images, it is evident that the MWCNTs evenly distribute on the alumina grains, and the length of MWCNTs is not more than 2 micrometers, which results from acid pickling and ultrasonic treatment for the MWCNTs.
There are a large number of pores in the composites, and the addition of MWCNTs will inevitably result in an increase in porosity and also inhibit the alumina grains growth during sintering.
