| 摘 要： | 通过两点温度脉动法，测量了孤立建筑物圆屋附近不同位置的折射率结构常数，对比分析了气象塔8.0，6.0 m高度处的折射率结构常数。结果表明：圆屋附近8.2，8.5，9.0 m高度处的折射率结构常数要比非圆屋附近同高度的结果大；距离圆屋等距离垂直方向的折射率结构常数大于水平方向的测量结果；因此将圆屋附近认为是近地面的假设不成立；圆屋附近温度谱幂率基本符合“－5/3”定律。

| Abstract: | Micro temperature method is used to measure the turbulence strength of different positions near the telescopic dome which is an isolated building. From analyzing the refractive index structure parameter near the dome and the same parameter at tower, the parameter of turbulence at altitude of 8.2 m, 8.5 m, 9.0 m are stronger than that of same altitude of general atmosphere. The refractive index structure parameters of equidistance between sensors and dome in different directions are different. The vertical turbulence intensity is stronger than the horizontal turbulence intensity. It is unreliable to consider the range near dome as near ground. The spectrum of temperature fluctuations near the dome follows the －5/3 law． |
