CakePHP使用find（）从模型中检索数据，数组键无法正确显示

I am using find to retrieve data from the database like this:

         $test = $this->VevD01VevDateYears->find('first', array(
            'conditions' => array('VevD01VevDateYears.D01_Vev_Type' => 1)
        ));

The expected array was suppose to be like this:

Array
(
[VevD01VevDateYears] => Array
    (
        [D01_Vev_Type] => 1
        [D01_Vev_Years] => 2014
        [D01_Vev_Date_Pub] => 2014-12-05 00:00:00
    )

)

Instead of the above array i get this weird one:

Array
(
[0] => Array
    (
        [VevD01VevDateYears__D01_Vev_Ty] => 1
        [VevD01VevDateYears__D01_Vev_Ye] => 2014
        [VevD01VevDateYears__D01_Vev_Da] => 2014-12-05 00:00:00
    )

)

I dont find anything wrong with the query and it returns the correct array when i retrieve data from other tables without messing with the keys. What is going wrong with this one?
