sound propagation constantとは 意味・読み方・使い方

The sample having a substrate surface vertical to a striated surface is prepared, and a bulk wave sonic speed [longitudinal wave sonic speed, horizontal wave sonic speed (a polarized wave direction is parallel to the striated surface)] in the propagation direction, which is parallel to the striated surface with respect to the sample, and density are measured to determine a sound related physical constant to form the standard sample.例文帳に追加

脈理面に対して垂直な基板面を有する試料を準備し、この試料に対して脈理面に平行な伝搬方向のバルク波音速（縦波音速、横波音速(偏波方向は脈理面に平行)）および、密度を測定することで、音響関連物理定数を決定して標準試料とする。 - 特許庁
