            </action>
        </reference>
</adminhtml_sales_order_view>
</layout>

Block file

    class <module>_Salesordertab_Block_Adminhtml_Order_View_Tab_Salesordertab extends Mage_Adminhtml_Block_Template
    implements Mage_Adminhtml_Block_Widget_Tab_Interface

{    
protected function _constuct()
{
    parent::_construct();
    $this->setTemplate('salesordertab/order/view/tab/salesordertab.phtml');
}

public function getTabLabel() {
    return $this->__('Operater Detail');
}

public function getTabTitle() {
    return $this->__('Operater Detail');
}

public function canShowTab() {
    return true;
}

public function isHidden() {
    return false;
}

public function getOrder(){
    return Mage::registry('current_order');
}

}

There is a little mistake in code.

  protected function _construct() /* here construct spell mistake */
{
    parent::_construct();
    $this->setTemplate('salesordertab/order/view/tab/salesordertab.phtml');
}
