在150 ℃和350 ℃之间的壁温下，研究了欧姆放电期间TEXTOR容器壁对氢的泵送以及随后的放电之间的氢释放。在放电开始时，容器壁显示出高的但瞬时的壁泵送速度，其随着放电的进行而减小。在放电结束时，壁泵浦速度趋向于约1 × 1020个氢原子/s的稳态值，因此放电后的氢释气遵循幂律（t）（t-O）。7·
The pumping of hydrogen by the TEXTOR vessel walls during ohmic discharges and the subsequent hydrogen release between discharges have been studied at wall temperatures between 150 C and 350 C. At the beginning of a discharge the vessel walls show a high, but transient wall pumping speed which decreases as the discharge proceeds. At the end of a discharge the wall pumping speed tends towards a steady state value of about 1 x 1020 hydrogen atoms/so Hydrogen outgasing after discharges follows a power law ()(t-O. 7•
