标准气温测定是在离地面5英尺左右的百叶箱中进行的。
Standard temperature observations are made in thermometer shelters about 5 feet above the ground.
温度表置放于远离障碍物的百叶箱中，以便取得自由运动空气的标准值。
Thermometers are placed in shelters far away from obstacles so as to get free-moving air standard values.
最后论述了不同类型百叶箱的滞后误差以及百叶箱的热惯性在测温中的应用。
Finally, the lag errors of different designs and the applications of shelter thermal inertia in temperature observation are also discussed.
