light water 【原子能】普通水〔與重水相對而言〕。

light-armed

The united states remains committed to the agreed framework which freezes and ultimately dismantles north korea s dangerous old nuclear reactors in exchange for safer light water reactors . as president bush made clear in seoul this february , we hope for a peaceful transformation on the korean peninsula 最后,北韓必須充份接受它在簽署核不擴散條約時同意接受的國際原子能機構的保障監督。美國繼續承諾遵守有關凍結并最終拆除北韓危險的舊核反應堆代之以更安全的輕水反應堆的框架協議。

Zirconium alloys are employed extensively in light water cooled reactors ( lwr ) as the cladding materials of fuel elements and other structural materials because of the low capture cross - section for thermal neutrons , good resistance to water - side corrosion at elevated temperature , adequate mechanical properties and high thermal conductivity 由于鋯的熱中子吸收截面小,并具有優異的耐高溫水腐蝕性能、良好的綜合力學性能和理想的熱導率,因此,鋯合金被用作核電站水冷動力堆核燃料元件的包殼材料和堆芯的其它結構材料。

The results showed that c . chinensis net photosynthetic rate , transpiratory rate , stomatal conductance were dereased with the increase of stress and the degress of the decrease were the least ones urder light water stress concentrations of intercellular co2 decreased with the increase of stress 結果表明:紫荊凈光合速率、蒸騰速率、氣孔導度隨著脅迫強度增加呈現出降低的趨勢,但在輕度水分脅迫時的降低最少;紫荊的細胞間隙co2濃度隨著脅迫強度的提高呈現出升高的趨勢。

Bwr is a light water reactor using ordinary water as coolant and moderator similar to the pwr except it only has a single circuit connecting the reactor and the turbine without a steam generator 沸水式反應堆是輕水反應堆的一種,這種反應堆和壓水式反應堆相似,均利用普通水作為冷卻劑及慢化劑,但沸水式反應堆只有一個連接反應堆和渦輪機的回路,且沒有裝設蒸汽發生器。
