 note = {It has already been reported in the previous paper how and what is the result of the field test of
the wind-velocity by the hot-wire anemometer at not only the entrance and the exit but in the interior
of the tunnel.
The present paper in this connection show the result of the field test of the above-mentioned case
with the direction-finding operation of the ultrasonic anemometer instead of the hot-wire anemometer.
Comprehending those results of the tests, it is safely argued that except at the entrance, the
'train-wind' is in the regular direction, that is, in the direction of the advancing train, by the time
when the train arrives at the position of the test ; on the other hand, when it arrives at the position
of the test the 'train-wind' runs in the opposite direction on the instant, but reverses itself in the
regular direction afterwards.
The time required for the 'train-wind' to return from the opposite direction to the regular one is
affected by the velocity and the length of the train as well as the lengh of the tunnel.
The result of the test alters in each case of the tunnels where the field tests were made, the
'Sonoyama-tunnel' has a blow-hole, but in the present test its influence will be regarded as little.
About the wind-velocity through the blow-hole, field tests will be made in due time hereafter.},
