悼戴恒昌君
(辛丑夏,2021年7月)

幸始逢君在爱城,
风华正茂何生生!
结邻岁岁常欢聚,
游历年年作伴行。
异乡求学艰难日,
高地识兄战友情。
重聚丹佛尤昨刻,
谁知一别竟终程!

【自注】
‘幸始逢君在爱城’:我1993年春到爱丁堡,戴君稍早于我先来,大家那时都是30多岁血气方刚的年青人。

‘结邻岁岁常欢聚’:在爱丁堡留学期间,我们家和恒昌家都住在靠近图书馆的大学宿舍里,我家是三楼,他家在四楼,大家经常在周末聚会,吃喝唱歌打牌,热热闹闹。每年也一起参加学联组织的春游活动。

‘重聚丹佛尤昨载’:我们搬来美国后,戴君曾经于2004年来丹佛开会,到过我家。没曾想这是与戴君的最后一面!

‘高地’(Highland): 泛指苏格兰。

Obituary: Hengchang Dai

Hengchang Dai, a senior research geophysicist at the British Geological Survey, passed away peacefully on the 5 July 2021 at Marie Curie Hospice, Edinburgh, Scotland after an eighteen-month fight with lung cancer. The professional community lost a gifted geophysicist, and we lost a dear colleague and friend.

Hengchang was born on the 16 April 1957 in Changli, Hebei province, China. He spent his early years travelling around China as his father moved between jobs. In December 1977, Hengchang was one of only two-hundred and seventy thousand aspiring students in China who passed the University entry examination. He was admitted into the University of Science and Technology of China (USTC), one of the top universities in the country. In 1982 he graduated with a BSc in geophysics from USTC, then continued his academic pursuits at the Institute of Geophysics, China Earthquake Administration, where he received an MSc in 1984. He remained as a research associate in the institute until 1991.

Hengchang moved to the UK in September 1991 to pursue a PhD at the University of Edinburgh, working for the Edinburgh Anisotropy Project (EAP), an oil company consortium based on the British Geological Survey. He received his PhD in 1996 and worked with the EAP for the rest of his life. Hengchang pioneered the application of neural networks to seismology in the mid 1990’s, publishing landmark papers which are still highly cited today. He also championed the application of parallel computing using PC clusters to process seismic data. He developed the CXtools package based on the Seismic Unix (SU) platform for processing converted-wave seismic data in the presence of anisotropy. The package is still very popular with the EAP sponsors and students. As a result, Hengchang travelled around the world to install the package and to give inhouse training courses to EAP sponsors. In 2012, EAP was the recipient of the Distinguished Achievement Award from the Society of Exploration Geophysicists, and Hengchang was one of the key contributors to this award.

In recent years, Hengchang spent much time teaching, supervising PhD students, and hosting academic visitors. He was always a supportive and generous mentor, giving advice in all aspects of student life whether academic or social. Hengchang was also an active reviewer for journal papers and an editorial member for the Journal of Geophysics and Engineering. 

Hengchang was a devoted husband and father, is survived by his wife Ying, and son Zhoudi, and will forever live in their hearts and minds as a caring and loving husband and father. Hengchang’s gentle personality and kind nature will be lovingly remembered by his many friends and colleagues, and all those whose life and work he touched. He will be greatly missed!

怀念老戴

1991年我和老戴是同时到爱丁堡的,也是我到爱丁堡认识的第一位挚友。他比我们稍年长些,我们都习惯称呼他老戴。96年老戴留在爱大,我到香港大学。我16年到北京工作,上网搜索在爱丁堡老朋友的信息,找到了老戴的工作单位和电邮,非常激动,加了微信,17年春节还通过微信互相问候。

上周突然收到从微信号“老戴”发来的噩耗:“张伟远你好,我是周英。恒昌生前嘱咐我,让我通知你。我和頔頔以万分悲痛的心情告之大家这一不幸的消息: 恒昌,经过18个月与肺癌的顽强的抗争,终因医治无效,于英国时间七月五日凌晨05:20am 永远的离开了我们”。

太突然了,太震惊了,真的无法接受,悲痛难以言表。老戴的音容笑貌时时出现在我的脑海里。在爱丁堡读博的4年中,大部分的节假日我们都是几家一起欢快度过的,最常聚的老戴一家、黄学跃一家、王永吉一家,还有后到爱丁堡的朱选一家、李宝成一家、李小锋一家、杨淑英一家、二虎一家、朱长青、小李、小毛等等。老戴一辈子为人和善,待人厚道;老戴身体健壮,个子高,红光满面,每次聚会都是主动承担搬桌子搬椅子的重活;老戴是研究地震的专家,知道我们听不懂,他总是博古通今地与我们谈论历史和文学;老戴是模范丈夫和慈爱父亲,对周英言听计从,对頔頔宠爱有加,是我们的楷模;……

往事依稀,泪眼朦胧。安息吧! 老戴,我们将永远怀念你。

追悼恒昌友

数十载好友一梦别
从此天上人间远
哭君匆匆别离去
淳朴音容仍犹在
生命不在水流长
终是流星也耀眼
人生如梭如烟雨
留住芬芳在人间

爱丁堡的老戴

在我的印象里,在爱丁堡老戴这个称呼只是属于戴恒昌的。

前几天得到老戴不幸去逝的消息,把我的思绪一下带回到三十多年前在爱丁堡的美好日光。回想到许多往事,但始终没有能想起为什么他和我年龄相仿长得也年轻而我们去那么愿意叫他老戴。大概是无论是平常生活还是做学问他比我们周围中国留学生更稳重些吧。

我是九一年在爱丁堡认识老戴的,学校把我们俩分配在Royal Miles学生公寓同一房间。他每日步行到Kings Building做研究。走回公寓满脸是汗。和老戴聊天,得知他知识面广且深。很惊叹他能把本厚々的书几天就读完。无论是英文的还是中文的。

再后来,我们俩家又合租了Bucceuch Street的一个宿舍。所以说跟老戴还是很有缘的。

那时我们左邻右舍住着不少中国学生学者,大家经常在一起砍大山。周英的高嗓门笑声和老戴的低调我们这些爱丁堡人大概还能记得。有时候我们也谈一些家庭琐事,我记得当时大家都说家庭和睦老戴周英当数第一。虽老戴也想反驳却找不到一个反例佐证。那是一段非常好的时光。

就写这些以寄哀思。

老戴一路走好

I am deeply grieved to hear that Dr. Hengchang Dai has passed away in such an young age. He was a kind nice and intelligent gentleman whose kindness touched all those who knew him. I know it was extremely difficult time for him and family during last 18 months struggle with his cancer. We are saddened by his death. Wish him now at peace. There is no pain in the heaven. We will always remember him.
