The results show that composite coatings of Ni-P-MoS2 have excellent antifriction and antiscuffing properties. The partical concentration of MoS2 and electroplating time have a great effect on its antifriction property.
he structures and properties of the blends, forming from several nylon-6samples with different concentrations of amino end group melt-mixed with maleic anhydride-functionalized EVA, have been studied. The results show that increasing amino end group concentration in nylon-6 will favor the forming of nylon-EVA graft copolymer,diminish EVA particles size and increase markedly the impact toughness.
Based on the plume physical model,a mathematical model describing mean velocity and liquid volume concentration of particle--gas--liguid three phase now in bottom--blown ladle is established.
It discusses that the effect of difference Polyethylene Oxide (Polyox WSR301) concentration in water solution on critical Taylor number and the velocity fields.
讨论了不同浓度的聚氧化乙烯( Polyox W S R301)水溶液对临界 Taylor数以及速度场的影响。
By the numerical simulation, calculate the distribution of velocity^ temperature and contaminant concentration of air in the room under different modes of air flow organization, and through analysing the outcomes of simulation, draw some conclusions.
The concentration distribution of a CO_2 jet in the wake of a circular cylinder is measured,and the effects of co-flowing air velocity and the diameter of circular cylinder on the concentration distribution of the CO_2 jet are presented.
So we can get the isoconcentration graphs, which show the concentration distribution of tracer directly. According to the graphs, we can carry out the search of the law of diffusion of pollutants and the evaluation of water environmental quality. At the same time, the experiment in this paper also shows the feasibility of pollutant concentration measurement in water body by digital image processing technique.
The concentration field of the particles with τ_p/τ_k≈1.0 showed that particles tended to be collected in regions of low vorticity (high strain) due to preferential concentration.
5. PLIF techniques are successfully developed to visualize and quantify the mean and turbulence characteristics of concentration fields of turbulent round jets in counterflow and coflow ambient. The cross-sectional scalar concentration fields, the characteristic jet width and the centerline dilution along the jet axis are also acquired.
More generally, these results apply both to Gabor frames and to systems of Gabor molecules, whose elements share only a common envelope of concentration in the time-frequency plane.
Transfersomal formulation with optimal concentration of Soya phosphatidylcholine (SPC) and sodium deoxycholate (85:15 w/w) showed entrapment efficiency of 39.8±0.032 and deformability index of 16.4.
