nginx rewrite rule

無名

小弟想以apache的rewrite rule轉為nginx的, 但轉換之後有些rule失效了. 想請師兄們指點一下.
Apache的:
RewriteRule ^\/?index\.html$ /html/index.html [L]
RewriteRule ^((ajax/|accounts/|software/download|shortcut|flashcookie)/?.*)$ /index.php/$1 [L]
RewriteRule ^\/?((cn|en|tw)?\/?([a-zA-Z][a-zA-Z0-9_\-]+)*\.html)$ /html/$1 [L]
RewriteRule ^\/?((cn|en|tw)?\/?news\/\d+)\.html$ /html/$1.html [L]

Nginx的:
rewrite ^/?index\.html$ /html/index.html last;\
rewrite ^((ajax/|accounts/|software/download|shortcut|flashcookie)/?.*)$ /index.php/$1 last;
rewrite ^/\/?((cn|en|tw)?\/?([a-zA-Z][a-zA-Z0-9_\-]+)*\.html)$ /html/$1 last;
rewrite ^\/?((cn|en|tw)?\/?news\/\d+)\.html$ /html/$1.html last;
