Under the constant blow ratio, the higher the mainstream velocity is, the higher the average effectiveness and average heat transfer coefficient are.

同一吹风比下，主流速度较高的，平均效率及平均换热系数也较高。

And the average heat transfer coefficient near the slots is different between different blow ratios, while far away from the slots, the difference diminish.

在主流速度较低时，这种情况并不明显。不同吹风比下反应出来的平均换热系数的差别在靠近缝口的区域较明显，沿下游方向这种差别逐渐减少。

Then average heat transfer coefficient of building external wall and heat transfer coefficient of building block filling wall by calculating were calculated.

由于常规算法的局限性，在实际项目中换算外墙平均传热系数与外墙主墙体传热系数需要计算的工作量较大。
