钠池 meaning in Chinese

sodium pool

2 ) . it has a great temperature gradient along the height in hot and cold plenums of cefr in steady state . the buoyancy force cannot be ignored because the flow velocity is low in the whole flow regions
冷热钠池在稳态工况下沿高度方向有很大的温度梯度，整个流动区域内的流速较低，浮升力的影响不可忽略； 3
3 ) . the flow velocity and temperature change rapidly in hot plenum under the transient condition such as in the case of reactor scram condition . thermal stratification phenomena will be observed nearby the inlet of intermediate heat exchanger
在事故停堆后的瞬态分析中，热钠池的流场和温场变化剧烈，并在中间热交换器的入口附近形成稳定的热分层。
Different from the previous procedure in which the hot plenum and cold plenum are calculated separately , the whole model including hot and cold plenum has been setted up in the present paper . it improves the calculation precision greatly . 2
首次将堆内的冷热钠池进行了一体化的建模，克服了以往将冷热钠池分开计算的缺点，使得计算的准确度大为提高，同时使计算的难度也大大提高，这种大规模的钠池分析计算国内外未见报道； 2
