| 释义 | shielding noun[ U ] uk /ˈʃiːl.dɪŋ/ us /ˈʃiːl.dɪŋ/ shieldingnoun[U] (STAYING AT HOME)UK a method of protecting yourself from a disease that involves staying at home and having as little contact as possible with people from outside your home, because you are at risk of becoming seriously ill if you get the disease: （以尽量减少接触等方式避免染病）屏蔽 If you’re clinically extremely vulnerable, you’re strongly advised to stay at home as much as possible and keep interactions outside to a minimum. This is called "shielding".如果你在临床上极其脆弱，强烈建议你尽可能呆在家里，尽量减少与外界的交往。这被称为 "屏蔽"。 People who have been given a prognosis of less than 6 months to live could decide not to undertake shielding. 被诊断为只能活不到6个月的病人可以决定不采取屏蔽措施。 Medicines & drugs: preventing infection anti-AIDS anti-bac anti-plague anti-rabies antibacterial antimicrobial antiseptic biosecure biosecurity boost cauterization containment rubbing alcohol scrub up shield social distancing sterility surgical spirit swab unexposed shieldingnoun[U] (PROTECTIVE BARRIER)sheets of metal, plastic, etc. used to protect workers or other people from harmful materials, diseases, radiation, etc.: The shielding protected the astronaut from the searing temperatures generated by the high-velocity descent. The team is examining new shielding materials that block more radiation than aluminium.

This is due to the difference in the shielding of the target nuclei between the two cases. The shielding is thus less effective in the completely ionized plasma and the angular dispersion of the scattered beam larger. In addition, a faster overall cycle time can be achieved which reduces the costs of consumables such as shielding gas. Especially large numbers of error was detected in the process from treatment errors occurring with the shielding blocks drew preparation to treatment delivery. Behind does a shielding operation by using the pictures in the second sequence to mask out overlapping portions of the pictures in the first sequence. The shielding level was about 10-6 of the terrestrial magnetic field. For background reduction, a careful shielding of the image intensifier against neutrons is required. Most of the work done on shielding so far, has ignored the effect of electron-ion trapping. These included optimum wiring technique, shielding and impedance matching. This also plays a role in neutron shielding. The shielding of a one-dimensional, planar, permeable test charge has been studied theoretically. It would, of course, require large shock-absorbers and ablative shielding for its pusher-plate. In this case, the heat conduction losses and the plasma shielding effects reduce the ablation efficiency. Shielding fails when the thermal boundary layer finally advances into the yielded region beneath the pseudo-plug. These examples are from corpora and from sources on the web.
