The cows jumped wildly over the five-barred barton-gate, maddened by the gad-fly; Dairyman Crick kept his shirt-sleeves permanently rolled up from Monday to Saturday: open windows had no effect in ventilation without open doors, and in the dairy-garden the blackbirds and thrushes crept about under the currant-bushes, rather in the manner of quadrupeds than of winged creatures.

奶牛被牛虻咬得发了疯，有五道横木的栅栏门都被它们跳了过去；从星期一到星期六，奶牛场的克里克老板卷起来的衬衣袖子，从来就没有放下来过。只开窗户而不把门打开，风是透不进来的；在奶牛场的园子里，乌鸦和画盾在覆盆子树丛下跳来跳去，看它们的样子，与其说它们是长翅膀的飞鸟，还不如说它们是长四条腿的走兽。

Since ventilation and evaporative cooling are the primary means for temperature adjustment in the duck house, a relationship for the traveling distance of water particles under various thermal environment was first established. This allows for the evaluation of efficiency of foggers for evaporative cooling. The relationship was then incorporated into a mathematical model based on the energy and mass conservation principle to simulate the transient change of outdoor temperature and humidity.

由於通风与喷雾降温为调节半开放式鸭舍内温度的主要方法，首先我们推导出雾粒在完全蒸发前移动距离与热环境条件的方程式，以计算於不同热环境条件下，不同大小雾粒的蒸发比率，从而评估喷雾降温的效率；次而利用质能平衡原理建立鸭舍内喷雾降温热环境模式，以计算及预测鸭舍内受外界热环境影响而产生的温湿度变化。
