However, the adsorption process is hard to be observed under current lab technique; also the adsorption time at the liquid-solid interface is the key factor of wetting efficiency.
In addition, according to kinetic parameters, the property changes of quartz particles surface after having adsorbed CTAB has been analyzed, the adsorption behavior of CTAB at the liquid-solid interface, and the microscopic essentials of wettability alteration have been further understood.
First of all, took 10mL CTAB solution with certain concentration into the stainless steel safety bottle, then added 0.1g quartz, the quartz and CTAB were mixed to disperse system by 60r·min-1 mechanical stir, then the heat effect curve and thermal effect data were tracked and collected by the Digitam4.1 software.

Second, detailed studies that have quantified the influence of hydrogen on fatigue crack growth behaviour, based on microscopic observations are very rare; most studies have only examined the influence of hydrogen on tensile properties.
From the term “HE”, we assumed that the higher the H-content in a material, the lower the strength properties of the material as shown in the previous section [7].
Fig. 14 Size of the hydrogen- affected fatigue crack growth zone (HAFCG zone) of a high- strength steel　(HV = 568), SAE 52100 [14].
The values of KTH for both the nonmetallic inclusions and artificial defects were definitely smaller than those for the large cracks, though the effect of some influencing factors, e.g., material type, strength level, hydrogen content, strain rate etc., should further be clarified in the future.
The threshold intensity factor KTH decreased with a decrease in defect size in the small crack regime.

The Visualization Research On Cavitation Flaw of The Jubilance Toy's Part With Different Wall Thickness Yong Li1,a, Yuxin Zhang1,b, Zhiqiang Sun1,c, Ruizhu Zhang1,d 1School of Mechanical Engineering, North China University of Water Conservancy and Electric Power, Zhengzhou in Henan,450045,China liongkm@163.com1a, zhangyuxinkm@sina.com 1b, sunzhiqiang@ncwu.edu.cn1c zhangruizhu@ncwu.edu.cn1d Keywords: Toy component; Injection molding; Plastic advisor; Cavitation flaw Abstract: The injection molding process with different wall thickness may create the obvious cavitation flaw.
The plastic material is the thermoplastic materials ABS, it has the prominent mechanical properties and the integrated performance, becomes an important engineering plastics[2],as shown in Figure1.The material’s density is 1.03-1.07g/cm3, the tensile is 30~50MPa, the bending is 41~76MPa, the tensile elastic modulus is 1587~2277MPa, the flexural elastic modulus is 1380~2690MPa, the shrinkage ratio is 0.5%.The material has good properties of heat-resistance , corrosion resistance and the bigger knockout; and the precision class for the high accuracy (3 levels of precisions), product requests outward appearance varnish, not varicolored, non-contraction patterns and so on
In the synthesis, chooses the injection mold with single parting line, the single-cavity mould, because many kinds of factor influences, for example, divides the profile to receive models in mould's formation position, gating system's design, the structure technology capability and the precision, the shape as well as promotes the method, mould's manufacture, the exhaust, the operation craft and so on, in addition is advantageous models a smooth drawing of patterns, and doesn’t affect the product the outward appearance, its single profile's position as shown in figure 3.

Non-linear Donnell´s theory for cylindrical shell is used to derive the equation of motion (the displacement in the radial direction): (1) Where is the flexural rigidity, c is damping factor, E is Young´s modulus, the density of the pipe and is the applied force to the pipe surface.
By replacing the mechanical properties of the pipe and fluid in the equations and using the ODE tool of MATLAB software, the pipe vibration at different points was calculated.
On the other hand the acoustic properties of the signal transmitter structure can affect the amplitude of the generated AE signals.

Combinating the nitriding with hardening allows us raising fatigue strength by factor exceeding 2, Table 1.
Nominal tensile strength raises from 420 ± 20 to 930 ± 50 MPa and does not affect the toughness of the material in comparison with the traditional method of heat treatment.
