In the vacuum tests a pole shift effect is observed, whereas in air no such effect is present. It is shown that the pole shift observed under vacuum conditions can be attributed to the inconstancy of the coefficient γ in the Zhurkov equation. In this case the activation energy of the ...
A comparison between thermal poling of silica in air and in vacuum is reported. It is shown that the second-order susceptibility and thickness of the nonlinear layer as well as their time evolution are highly dependent on the surrounding poling atmosphere. In the vacuum case a charge distribution...
Vacuumize the gauge and piping separately according to the criteria for vacuumizing the system. The piping for vacuuming the system must be simple and the vacuum gauge must be closely connected to the unit. Check whether the outdoor unit is equipped with a refrigerant pump. If the outdoor ...

摘要: A plenum/vacuum chamber for providing air circulation in a room. The chamber is attached to a housing affixed over an opening in the wall of the room and extends into the room. The housing has a grille passing therethrough which has an air-tight compartment around it....
We demonstrate an implementation of this approach by efficiently deflecting ultrashort laser pulses using ultrasound waves in ambient air, without the use of transmissive solid media. At optical peak powers of 20 GW, exceeding previous limits of solid-based acousto-optic modulation by about three ...
While this is a little lower than those mentioned above, it’s worth accounting for the size difference, which is why this air purifier features so high on the list. Noise (low) Noise (high) Power use (kWh) 36.8 dB 58.3 dB 0.082 kWh It was also top of the class for energy ...
The storage of CO2 and hydrogen within depleted gas and oil reservoirs holds immense potential for mitigating greenhouse gas emissions and advancing renewable energy initiatives. However, achieving effective storage necessitates a thorough comprehension
In addition, the natural convective heat exchange with the ambient air introduces another term h(T∞ − T), where h is the heat exchange rate and T∞ is the room temperature. In order to reduce the influence of ambient air convection, we set the system in a vacuum chamber (see Supplem...
