OK, but probably not quite what you meant, this maybe:
RewriteCond %{HTTP_HOST} ^www\.abc\.com$

> RewriteCond %{REQUEST_URI} !^index\.php$
Always true, REQUEST_URI will *always* start with a slash, you probably
wanted:
RewriteCond %{REQUEST_URI} !^/index\.php$

> RewriteCond %{REQUEST_URI} \.php$

This rule will indeed rewrite
/show.php to http://www.abc.com/show
as you have not specified any query string in the right hand side, the
original will be preserved, making http://www.abc.com/show.php?tid=1 ->
http://www.abc.com/show?tid=1

Try adding
RewriteCond %{QUERY_STRING} &?tid=(.+)&?
and changing the rule to be:
RewriteRule (.*)\.php$ http://www.abc.com$1/%1? [R]

Dear Phantom,

thanks for your nice reply, according to your suggestion I have
adjusted the rules like:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.abc\.com$
RewriteCond %{REQUEST_URI} !^/index\.php$
RewriteCond %{REQUEST_URI} \.php$
RewriteCond %{QUERY_STRING} &?tid=(.+)&?
RewriteRule (.*)\.php$ http://www.abc.com$1/%1? [R]
</IfModule>

I'm glad to see, now the link already be referred to : from
www.abc.com/show.php?tid=1 to www.abc.com/show/1, which is great.
But the 404 not found error still exists, here I attached the log:

cool!!!
with you suggested, I modified the rules as:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.abc\.com$
RewriteCond %{REQUEST_URI} !^/index\.php$
RewriteCond %{REQUEST_URI} \.php$
RewriteCond %{QUERY_STRING} &?tid=(.+)&?
RewriteRule (.*)\.php$ http://www.abc.com$1/%1? [R]
RewriteRule ^/show/(.+)/?$ /show.php?tid=$1 [L]
</IfModule>

and now it works pretty well.

To completely understand this part, I have following to ask:
1. what should I do if I have parameters in a url like:
www.abc.com/show.php?tid=1&rid=a&zid=ab12 while I want to turn it
into: www.abc.com/show/1/a/ab12
tid only allows numbers; rid allows letters; zid maybe a mix.
how to write the rule? and will the php automatically recognize
from the url, tid should be 1, instead of a?
after learn how to deal with above case, I think I could master
this rule

2. after I turned this mod_rewrite on, found I have to change my
previous links in the pages.
for e.g. previous I will write the a link in page like <a
href="abc.php>abc</a>, now have to modify it into <a href="/
abc.php>abc</a>
for images, have to do like <img src='./images/q.png' /> to <img
src='/images/q.png' />
I want to understand, will this changing affect the server's
response, which is better?

3. on browsing some webs, when place mouse on a link, on the IE status
bar will appears like "abc/123" instead of "abc.php?uid=123",
according to our current mod_rewrite request, does that mean I'd
better to to modify all the existing links as well?

All of your kind guidance are much appreciated.

If you're getting a 404 that would suggest that you do not have a
file/directory at
<DOCUMENT_ROOT>/show/1
or as your log suggests
> rewrite '/show.php' -> 'http://www.abc.com/show/177?'
a file/directory at
<DOCUMENT_ROOT>/show/177

I suspect you are going the wrong way, would the following be what you are
actually trying to achieve:

a user types in the URL http://www.abc.com/show/177 this URL is then
processed behind the scenes by
http://www.abc.com/show.php?tid=177 without the user ever seeing this
second url?

which would be achieved with something like this:
RewriteRule ^/show/(.+)/?$ /show.php?tid=$1 [L]
