Application of Dispersibility Mechanism for the Dispersibility of ZrB2 Powder Materials in the Liquor Jieguang Song1a and Xiuqin Wang2, Minghan Xu1, Shibin Li1, Gangchang Ji1 1 Jiujiang Key Laboratory of Green Remanufacturing, School of Mechanical and Materials Engineering, Jiujiang University, Jiujiang, Jiangxi, 332005, China 2 Library, Jiujiang University, Jiujiang, Jiangxi, 332005, China a songjieguang@163.com Keywords: Dispersibility mechanism; Sedimentation method; ZrB2 particles.
Introduction With the fast development of preparing new materials, the conglobation and decentralization problem of superfine powders already is key factor for preparing and developing new high-performance materials [1].
In the bypast study, zirconium diboride (ZrB2) and yttrium aluminium garnet (YAG or Al5Y3O12) both have attracted substantial interest, because of their extreme chemical and physical properties, especially high-temperature strength and stability, they are diffusely applied in some industries [3].
ZrB2 have some excellent properties, however, it is restricted for the broader applied range, because it is oxidized in the high-temperature air to impact high-temperature strength [4].
Because ethanol, propanetriol and polyethyleneglycol are the non-ionic dispersant, their character is not affected with the variation of electrolyte and pH, and the solubility is very big in the water.

Introduction As everyone knows, the weight of the aircraft directly affect the performance of the aircraft, and the structure optimization can greatly reduce the structural weight, therefore in the field of aviation field the structure optimization carried out a lot of study[1].
For the complex structure of aircraft wing like structure, size optimization design method has been very mature, but the layout design of the study, the main difficulty is the layout optimization involves different finite element model, multi variables, variables and large difference of properties, there are mixed discrete variables.
Click on the Optimization Control Parameter option, in this page, the initial density parameter, topological optimization of the minimum limit, the maximum number of cycles, the penalty factor, extreme sports, convergence tolerance and minimum structural size of definition.
Beam-front wall-backwall and the arrangement form bionics ribs so that the use of force is more uniform, the material properties are more fully utilized, the structure is more efficient.

The physical, chemical and other properties of matters will change a lot in case of nanometer scale.
Select and culture neural stem cells for 7 to 9 days and perform mechanical separation of neurospheres for passage.
In previous study, one or more growth factors are used to induce differentiation of NSCs.
However, differentiation of NSCs is affected by many factors and is a result of a variety of factors.
However, the physical, chemical and other properties of matters will change a lot in case of nanometer scale.

The degree of cladding corrosion is a complex problem that is not only related to the properties of materials, but also to the environment [1].
Transition is one of the main factors that determine the corrosion resistance.
They collectively affect corrosion by changing the oxygen diffusion rate in the oxide film, by changing the mechanical property that influences the undulation development, or by changing the stability of tetragonal phases.
The smaller valence of Sn will produce large amounts of oxygen vacancies inside the oxide, increasing the number of vacancies and affecting the stability of tetragonal phase.
Different elements have different physical and chemical properties.

As there are always certain defects on the final surface of large-scale lightweight mirrors, which are formed in traditional mechanical polishing process, such as microcracks, lattice disturbances, plastic deformation, and so on, an atmospheric pressure plasma polishing method is a good solution to this problem.
Since the machining process is chemical, surface material can keep its intrinsical properties with no surface/subsurface defects introduced.
Fig. 1 A sketch map of the structure and function of the plasma torch Plasma torch is where plasma and reactive radicals generate, so many factors, which will affect the discharge state and plasma characteristics, should be considered in the design and fabrication process[6,7].

Zhang et al. [18-19] firstly developed a multiple shell model and estimated the effect of a small length scale on the properties of vibrations of nanotubes.
The obtained results in this paper can provide useful guidance for the study and design of the next generation, and used in the construction relies on a host of mechanical of such nanodevices that make use of the mechanical buckling properties of zigzag Triple-walled carbon nanotubes. 2.

An explosion generates a supersonic shock wave, causing a significant impact on human lives and properties.
Furthermore, the L/D ratio of TNT and stirrup configuration play important roles in determining the extent of damage and the residual capacity, highlighting the need to carefully consider these factors in designing columns subjected to contact explosions.  
Recently developed ultra-high performance concrete (UHPC) shows higher mechanical properties, namely compressive and tensile strength and ductility [10-11].
Effect of L/D ratio of TNT The explosive shape directly affects the peak pressure and impulse imparted to the structure.
Furthermore, the L/D ratio of the TNT significantly affected the column’s damage pattern.
