摘要: We describe a very simple experiment that allows college students in introductory physics courses to plot the I-V characteristics of a solar cell, and hence measure important photovoltaic parameters, such as the fill factor and light conversion efficiency. ...
Each experiment consists of a gas-free surfactant injection phase, followed by a foam injection phase, which is then followed by a brine injection phase simulating the post-foam acid injection stage. The pressure data along each core at four locations and the weight of the liquid effluents for...
This paper investigates the regularity of microstructural evolution of Shenzhen granite residual soil in an attempt to determine its macrostructural deformation characteristics. The pore distribution and microstructure characteristics of granite residual soil are examined experimentally under different consolidation...
to study the failure mode and fracture evolution characteristics of red shale in Kaiyang Phosphorus mining area, conventional triaxial compression mechanical tests of red shale with different bedding dip angles were carried out by using DSTD-1000 electro-hydraulic servo rock mechanics experiment system. ...
It is found that using an air curtain can have energy savings up to 40 and 11%, respectively, compared to the cases without an air curtain and using plastic strip curtain. Comparison between the experiment and numerical results also shows reasonable agreement in terms of average temperature ...
The major features of the liquid-phase model are that a SSF approach is used to represent the effect of gas-phase turbulence on droplet trajectories and vaporization, an infinite-diffusion model is employed to represent the transient liquid-phase process. Computation and experiment results show that...
A vacuum pump precisely controlled the air in the test section before an experiment started. Steam was generated at the bottom of the vessel by Verification The average HTCs of pure steam condensation on the bare tube under different steam pressure are depicted in Fig. 7. The results present ...

So there you have it. Try a few of these attitude adjustments for yourself — maybe just as an experiment if you can’t face the idea of actually changing anything permanently about yourself. Let me know what happens. [all words] [any words] ...
Here, a defect in the SiO2 is working as an electron trap. To the gate electrode, programming pulses for the electron trapping are applied. After that, the retention characteristics is monitored as a function of time. To accumulate effects of pre-synaptic stimulations, this sequential experiment...
