在纪念《水力发电》出版200期之际,我作为这一刊物的两届编委会主任,谨代表编委会向长期以来关怀和支持我们工作的各级领导和广大作者读者表示衷心的感谢。记得1982年8月,在纪念《水力发电》出版100期时我曾说过:“今天我们举办100期纪念,以后还要举办200期、300期纪念……一直下去,因为水力发电事业是永存的!”。时光 On the occasion of the publication of the 200th issue of Hydropower, I, as the director of the two editorial boards of this publication, on behalf of the editorial board, extend my heartfelt thanks to all levels of leaders and readers who have long cherished and supported our work . I remember in August 1982, when I was commemorating the publication of “Hydroelectric Power”, I said 100 times: “Today we hold 100 commemorative ceremonies. We will organize 200 and 300 commemorative ceremonies ... till now because the cause of hydropower will last forever of!”. Time
