７．３．４ 试验台主要部件的作用７．３．４．１ 温度采样装置温度采样装置（图１０）由采样管、温度测量盒、取样风机及连接风道等组成。采样管（图１１）能较均匀地取出被测断面的空气样，以便准确测量平均温度。温度测量盒内放置温度传感器或玻璃棒标准水银温度计。取样?
7.3.4 Role of the main components of the test bench 7.3.4.1 Temperature sampling device The temperature sampling device (Figure 10) consists of a sampling tube, a temperature measuring box, a sampling fan and a connecting duct. The sampling tube (Figure 11) allows more uniform removal of the air sample from the section under test in order to accurately measure the average temperature. Temperature measurement box placed temperature sensor or glass rod standard mercury thermometer. sampling?
