>>416 補足 >He spent 1965-67 as a Member of the Technical Staff at Bell Telephone Laboratories, Murray Hill, N.J. and then joined the Physics Department at McMaster.
Dr.D.W.Taylorは、1965-67にベル研（Bell Telephone Laboratories）に居た P. Sovenの所属もベル研で、 (1967)の論文で、"ACKNOWLEDGEMENTS We wish to acknowledge helpful conversations with Dr.M.Lax and Dr.D.W.Taylor.">>411とあることと符合する （分かっていると思うが、ftp://www.phy.pku.edu.cn/pub/Books/%CE%EF%C0%ED/%CE%EF%C0%ED%D1%A7%CA%B7/Phy_Rev_100%C4%EA%BE%AB%D1%A1/pdf/09/083.pdf は、httpではないのでURL窓にコピーして飛ばないとｐｄｆには行けない）
