It is with great sadness I learn of the passing of Professor Xie Jialing. I had known him for many years and he had visited me many times. 　　 

　　Please extend my deepest sympathy to his family.  

　　請代我向谢家麟教授的家屬轉達我的哀悼之意。 

　　我第一次認識谢教授是在1975年11月到北京高能所訪問時，近幾十年來，多次與谢教授討論加速器，從他那裡獲得到很多知識，谢教授是很有學問也是我很尊敬的科學家，他去世是世界科學界很大的損失。
