由此可推出进、出口的流量系数不同，从而得到一种简单的估算自然通风量的计算方法。

From this, we can conclude that the discharge coefficients of the inlet opening and the outlet opening are different.

同时，通风量及冷却数随外界侧风风速的变化规律在不同的流量下相似，说明所得结论具有通用性。

Meanwhile, the variation regularity of ventilation and cooling number with wind speed at different flow rates air similar illustrate the conclusions of generality.
