independently; (3) The model is static and the measurement is convenient
and accurate; (4) Test is generally not affected by changes in the atmosphere.
The disadvantage is that it is difficult to meet all similarity criteria, and there
is cave wall and model support interference, which can be overcome by data
correction.
