模拟计算结果表明：与其他领域应用的旋风分离器相比，五边形入口、三心大涡壳式旋风预热器内筒入口附近次级流动相对较弱；
The results of the simulation indicate:compared with cyclone in other domain, the secondary flow of the preheating cyclone with pentagonal inlet and three core volute structure is relatively weaker.
1831年，迈克尔·法拉第(Michael Faraday)发现，在一根电线内流动的电流会在邻近的一根电线内产生次级电流(secondary current)。
Michael Faraday discovered in 1831 that an electric current flowing in a wire induces a secondary current in a neighbouring wire.
我可以告诉你。我们增加了次级市场的资产流动性。我们削掉了收益差的基点。
I'll tell you. We increase the liquidity of the secondary bond market. We shave basis points off of spreads.
