On-site application and effect analysis In the oil well hydraulic fracturing process, there are four main factors impact on fractures vertical extension, that is the elements of controlling fracture height: reservoir stress difference, rock material properties, fracturing fluid performance parameter, height growth, the bigger the reservoir stress difference, the smaller the fracture height, construction parameters and so on[2,4]
(2) As far as rock material properties concerned, the greater factors impact on fracture vertical extension are Young's modulus, fracture toughness, Poisson's ratio, permeability, reservoir thickness and so on.

As with screw conveyor, the vanes of spiral rotate with the shaft together also, but materials are rotating and transported in the trough formed by material and keep dropping at the same time.
This is the root cause of segregation of the material when the paver works.

In this study, the solid-state reaction to form Mg2Si bulky materials via spark plasma sintering (SPS) process was discussed.
From a view point of the shrinkage and densification of Mg2Si bulky materials during SPS, the sintering conditions of Mg2Si intermetallic compounds were optimized.
Experimental Mg (purity 99.9%, mean particle size D50=121.6µm) and Si (99.9%, D50=20.03µm) were employed raw materials.
Sintered of Mg2Si Bulky Materials Figure 4 shows a dependence of temperature and relative position of Mg-Si specimen on sintering time.
