摘　　要：在夏季 ,由于庭院的遮挡作用 ,东西各墙内表面只依次得到一定时间的太阳直射照射。该文推导了遮阳系数 ,并通过实验测试和计算机模拟 ,证明了庭院厦房和廊檐对太阳辐射的遮挡和窄长形状是造成庭院夏季凉爽的主要原因。Owing to the shielding effect of the yard, the inner surface of the west and east wall can only get a certain of solar director radiation. In this paper, the shielding factor was deduced. It was prove by the fieldwork and computer simulation that the shielding effect of the aisle and side house and the long narrow shape are the main reason that make the temperature of the yard lower.
