ACKNOWLEDGMENTS<br />
First, I wish to express my sincere gratitude to my advisor, Jerry Harris. His<br />
support, inspiration and stimulating advice are major factors for the successful<br />
completion of this dissertation. Jerry is always available for discussions. His physical<br />
insight and numerous interesting ideas makes the discussions fruitful and enjoyable.<br />
Jerry not only emphasizes theoretical research, but also encourages us make efforts to<br />
applied research.<br />
I also wish to express my appreciation to Kiyoshi Yomogida. It was his help that<br />
made my study at <strong>Stanford</strong> <strong>University</strong> possible. Even after Kiyoshi left <strong>Stanford</strong>, he still<br />
gave me many useful suggestions on my work.<br />
Special thanks to Xiaofei Chen of <strong>University</strong> of Southern California, my friend<br />
and college classmate. During last a few years, close cooperation between us led to<br />
several papers published regarding to the borehole wave simulation. Xiaofei provided<br />
extremely valuable help on the development of the wave propagation theory. Nick<br />
Smalley was my office-mate. Daily conversation between us gave the office life much<br />
pleasure. Nick edited many papers of mine. <strong>My</strong> attenuation tomography program was<br />
modified from a velocity tomography code originally written by Feng Yin. Feng gave<br />
me many help on the attenuation work. Thanks to Mark Van Schaack for the work he did<br />
on the computer system management and field data editing.<br />
Dan Moos gave me many suggestions on sonic logging and wave modeling. Dan<br />
very carefully reviewed my dissertation and explained all comments to me in person. I<br />
also would like to thank Norm Sleep and Greg Beroza for reading this thesis. I had many<br />
discussions with Gary Mavko when I started to work on the attenuation project. He gave<br />
many stimulating suggestions.<br />
