Explanation of Special Characters in This WWW Publication

• Greek letters are coded for the symbol font. Current versions of Netscape and Internet Explorer running on machines that have the symbol font will render these symbols properly. Some other browsers, and those running on machines without the symbol font, will show these letters as the corresponding Roman letters: for example, epsilon will be shown as the letter "e".

• Subscripts and subscripts are coded with the <SUB> and <SUP> codes. Most newer browsers should interpret these codes properly.

• The lowercase letter "x" is used for the times sign. Some special characters are replaced with their word meanings, like "angstrom" and "infinity."

• GIF files are used for complex equations.

• Tables are coded in the HTML 2.0 format.
