在进入正题之前，我想先把ARM920T的异常向量表（Exception Vectors）做一个简短的介绍。-Before entering the subject, I would like to first abnormal ARM920T to Scale (Exception Vectors) do a brief description here.
SHOW FULL COLUMNS FROM `jrk_downrecords` [ RunTime:0.001254s ]
SELECT `a`.`aid`,`a`.`title`,`a`.`create_time`,`m`.`username` FROM `jrk_downrecords` `a` INNER JOIN `jrk_member` `m` ON `a`.`uid`=`m`.`id` WHERE `a`.`status` = 1 GROUP BY `a`.`aid` ORDER BY `a`.`create_time` DESC LIMIT 10 [ RunTime:0.095777s ]
SHOW FULL COLUMNS FROM `jrk_tagrecords` [ RunTime:0.001206s ]
SELECT * FROM `jrk_tagrecords` WHERE `status` = 1 ORDER BY `num` DESC LIMIT 20 [ RunTime:0.001944s ]
SHOW FULL COLUMNS FROM `jrk_member` [ RunTime:0.001308s ]
SELECT `id`,`username`,`userhead`,`usertime` FROM `jrk_member` WHERE `status` = 1 ORDER BY `usertime` DESC LIMIT 10 [ RunTime:0.003693s ]
SHOW FULL COLUMNS FROM `jrk_searchrecords` [ RunTime:0.001067s ]
SELECT * FROM `jrk_searchrecords` WHERE `status` = 1 ORDER BY `num` DESC LIMIT 5 [ RunTime:0.003476s ]
SELECT aid,title,count(aid) as c FROM `jrk_downrecords` GROUP BY `aid` ORDER BY `c` DESC LIMIT 10 [ RunTime:0.015487s ]
SHOW FULL COLUMNS FROM `jrk_articles` [ RunTime:0.001451s ]
UPDATE `jrk_articles` SET `hits` = 1 WHERE `id` = 176692 [ RunTime:0.001451s ]
