容控箱收集净化、过滤后的下泄流，同时它给上充泵提供净正吸入压头。
The volume control tank collects the purified, filtered letdown fluid and provides a suction reservoir and head for the charging pumps.
所有的树脂床对温度都有要求，因此当温度超过预定值时，下泄流将旁通净化床运行。
All of the ion exchanger resins are temperature sensitive; therefore, a temperature diver valve bypasses letdown flow if the letdown heat exchanger outlet temperature rises to a predetermined value.
宽尾墩应用于高拱坝表孔后，其下泄水流的空中扩散特性与宽尾墩流道内的水流特性密切相关。
When flaring gate piers are on surface spillways in high arch dam, the dispersion of plunging jets from surface spillways is closely related to the charateristics of flow.
