stably

The system operated stably for a long period and demonstrated its ability to produce hydrogen continuously.

The amount of hydrogen squeezed out increases with pressure and depth, forming a stably stratified carbon-nitrogen-hydrogen layer, almost like a plastic polymer, he said.

The electrolyzer stack performed consistently and stably for over 125 hours -- a testament to its robustness, Jiao said.

Overall, the volunteers were able to stand stably with much less effort when assisted by the robot, compared to when they tried to stand alone while wearing the bulky suit.

They are also limited by the power of their lasers, which they spent years carefully tuning to work stably at the desired wavelengths.
