P2, P3, P4分布の波動が出る場合に,√μ/ρ=1km/sではそれ等の無限大遠方に於ける振幅は1, 0・184, 0・0276, 0・00316となる.然るに√μ/ρ=0・1km/sになると同じ振幅は17・3, 17・3, 17・9, 18・2となり,√μ/ρ=10km/sになると0・03866, 0・04185, 0・06296, 0・07333となる.即ち初動分布から震源機構を推定するには震動週期が違ふと結果が勿論違ふけれども,その媒體の彈性等が異なるものであると又同様に著しく異なる結果が出ることを示すものである.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"134256","nameIdentifierScheme":"WEKO"}],"names":[{"name":"妹澤,
