The main idea of studying the geological properties of natural gas in China is that tostart from basin analysis,take thermal effect as fundamental principle,and use the view-point of dynamic equilibrium.
This article theoretically analyses the laser's thermal absorption effect of metal materials, and then through preheating technology to improve the heat effect on the material's surface from the laser beam pattern, so that the solid laser instrument's processing precision can be improved from ±0.03mm to ±0.001mm.
Results The heat effect of the conventional method was not stable and its penetrating heat effect was poor, though the temperature was raised significantly at o cm and 1 cm (P<0.001).
At 505℃, the initial strain rate ε=1.67×10 -4 s -1 to the stretch, and the maximum elongation 465.5% and flow stress 2.49 Mpa can be reached. The deformation and heat action cause the growth of crystals in the process of stretch.
The condition of structure and heat action to form electron beam melt-brazed joint was given. Based on microstructures and the characteristics of electron beam welding, the physical model that decribed formation process of EB melt-brazed joint of QCr0. 8/1Cr21Ni5Ti was proposed and formation mechanism of the joint was discussed.
Objective:The effect of heat action on the dymanic changes of enzyme,alkaline phosphatase (AKP),acid phosphatase (ACP) and succinic dehydgenase (SDH),and biological significance of enzyme in the process of spermiogenesis were studied to provide morphological data for male antifertilization.
To evaluate the coverage of the reservoir by the thermal effect, we must know the temperature distribution in the multi-well reservoir system at any instant of time.
Equations are derived for calculating the rate of mass loss (ablation) and the thermal effect of physicochemical transformations taking place on the surface during the transient heating of glass plastics with coking binders.
On the basis of the experimental study of its thermal interaction with air oxygen, a method for fabricating new oxide/n-CuIn5Se8 heterojunctions is proposed.
From the power-times curves, the maximum power (Pmax) in the log phase, growth rate constant (k), generation times (tG), time of the maximum power (tmax), heat effects (Qlog) for log phase, and the total heat effect in 45 h (Qtotal) of.
As the amount of energy consumed during the mechanical treatment of powders increased, the value of the heat effect rose synchronously with the degree of amorphization.
The skin temperature patterns are shown to be informative when analyzing the organism's heat state and forecasting the extent to which the total working capacity decreases in response to the intensive heat effect.
The direct calorimetry method was used to measure the heat effect of the L-asparagine reaction with the Ni(II) nitrate solution in different pH intervals at 298.15 K and at the 0.5, 1.0, and 1.5 ionic strength (KNO3).
