介绍一个教埃及语的网站
http://ancientegyptonline.co.uk/hieroglyphs.html
不知道大家觉得这网站如何
本人英文不太好
所以这网里的英文有些看不懂
想请教些问题

1.如果是表意符号就会在符号下面划一条线来表示吗？
原文：Logograms
A logogram (or ideogram) represents
an entire word. Many logograms are also determinatives and phonograms. If the
sign is intended to act as a logogram, there is usually a vertical line beneath
it. For example, sign for the letter "r" becomes the sign for word
"mouth" when written with a vertical line (indicating it is a
logogram).
2.在转译象形文字时是要在什么情况下加e和a后面加h？为什么要加？
要如何转译加e或a后面加h？
例如

 

3.这网站有提供迦德纳福号列表里面代码有些看不懂可以帮我翻译吗
