One of the essential concepts of Buddhism is that every thing is the
result of an assemblage of resources and conditions, not of a single
cause.  Such a concept is tailor-made to describe the fulfilment of my
project.  The assembled resources and conditions are the following
people whom I have to thank one by one: 
\\

\noindent
Thanks to supervisors for their advice and guidance of the development 
of a project is not enough for my supervisor {\sc Dr A.Hamilton} because
he was much more than that.  He was always there and ready to help;
always smiling even when my question was annoying and sounded rude; always
patiently explaining even when my question was quite childish.  Moreover, he
could speak out my question and answer it before I tried to ask in more
sensible English.  So I sincerely thank him for his help, patience,
consideration and smiling expression.

Special thanks to Anne Bailey, acting as if my private advisor, for her
suggestions and help. She was more anxious and enthusiastic about the
project than I.
\\

Thanks are also due to: \\
Mr R.Bland for suggesting to me the project and for lending me a
book. \\
Sam Nelson for building up the translation tool {\tt ptc} on {\it forth}
\\
Peter Lee Teck Hwa for lots of Latex assistance. \\
Jonathan Harston for helping with my English grammar and general
assistance.

During the course of this project, I felt I was a {\it protected animal}
with people flocking together, providing help and showing concern.  So I
deeply appreciate all those who ever helped me again and again, forever
and ever .........
