Due to the influence exerted by many factors such as turbulence’s environmental restriction, physical property and external interruptions, traditional contact-type signal acquisition is vulnerable to interference, and qualitative and concrete research on turbulence’s characteristics is beyond their capability (emulation and imitation of turbulence field, etc).
Conclusions Fitting curve discipline of turbulence locus based on image projection transformation and light stream vector is investigated: (1) the controllable velocity range of its influence on turbulence curve characteristics is from 5cm/s to 20cm/s, exceeding velocity will leads uncontrollable turbulence; (2) under condition of low flow velocity (5cm/s-20cm/s) all characteristics display a tendency of continuously increasing, but change distinctly in high velocity; (3)When combining with turbulence characteristic’s variance discipline and affecting degree, it is suggested that research on turbulence discipline is implemented in condition of low flow velocity (<20cm/s).

Here we focus on several key issues and factors that will provide some context and background for the work.
Even the 5-min value (109°) may be affected.
Several factors contribute to this.
Thermophysical properties must be matched to avoid undesirable residual stresses, limiting the choices.
Simple bend tests can provide information on the reliability and reproducibility of joint properties.

Geopolymer requires an alkaline activator to induce it pozzolanic property and to accelerate the geopolymerisation process.
As CO2 emissions from OPC kilns play a significant role in global greenhouse gas concentrations, this may be a large contributing factor in the incorporation of geopolymers into cement and concrete applications [2].
Hence, the ratio of fly ash to alkaline activator and the ratio of sodium silicate to NaOH affected the strength of the geopolymer.
Furthermore, the ratio of fly ash to alkaline activator and the ratio of sodium silicate to NaOH indicated the parameters affecting the compressive strength of the geopolymer [6].

Titanium and its alloys are the main metals studied as porous metallic implants by their excellent mechanical properties and biological interactions.
Introduction Biomaterials based on titanium and its alloys are widely used in orthopedics and dentistry due to their excellent mechanical properties and biological interaction.
The porous polymeric systems face the same difficulties in relation to mechanical stress, this has led to more intense research for the processing of metals, especially titanium [1,3].
This characteristic indicates that the thermal treatment up to 500°C does not affect the oxidation of the metal and provides a good operating range (Fig.1 C2).
The topography of the implant is a factor that directly influences the quality and success of osseointegration, thus the implant surface roughness is a desirable feature and with PM to achieve it, there is no need of further processing to obtain it, as needed for surface treatments.

Then the samples were cut into pieces of 14mm and 2mm.Their impact properties and tesile property were tested.

In a period of plumbum solder , because of the incompatibility of plumbum and palladium , can interfere with the formation of uniform IMC (Intermetallic Compound) layer, thus affect the reliability of solder joints, limited the application of the coating quality.
Therefore, market urgently need for a surface coating technology for PCB , which is not only with excellent coating properties, but also high welding reliability.
Having electroless nickel on welding board copper surface is under catalyse action of Pd , NaH2PO2 hydrolyze to create atomic state H , while H atoms is in Pd-catalyzed condition , Ni2+ will be deoxidized to nickel metal and deposited on the bare copper surface, this new created Ni has become catalyst of continuing to promote reaction, as long as various factors of the solution are controlled and added , will be got any thickness nickel plating.

In this way, on the one hand the designers can innovative design the mechanical devices through heuristic approaches about the mergers, conversions and so on etc; On the other hand, record the changes of design knowledge in the course of innovation [1].

Its principle is, the structure size associated with kinds of parts as the overall parameters, the parts of the structure size parameters which decides itself as local parameters; The structure sizes which is calculated on the basis of the overall parameters and local parameters as auxiliary parameters; The independent parameters that does not affect other parts sizes define as irrelevant parameters Which the main driving parameters of the reasonable or not are the crucial factors is whether the holographic knowledge of assembly accurately express or not.

The strength and impact energy (AKU at room temperature) are approximately 1600MPa and 80J respectively, which demonstrates outstanding combination of strength and toughness. [1-3] In order to ulteriorly enhance the toughness and consequently improve fatigue and other mechanical properties, the CFB/M steel is micro-alloyed with Nb (CFB/M-Nb) to refine the grain.
All of these factors cause the phenomenon of strong structure transmissibility.
Electrical inductance heating utilizes high-frequency electricity to heat metal specimens, and the heating method itself may affect the nucleus formation and growth of grains.
