擅离职守

The officer was convicted of desertion at a court martial.

这名军官在军事法庭上被判犯了擅离职守罪。

Possibly I might be blamed a bit for my truantry, but the recapture of the Hispaniola was a clenching answer, and I hoped that even Captain Smollett would confess I had not lost my time.

也许会因为擅离职守而受到，夺回伊斯班袅拉号则是最有力的答。希望就是斯莫列特船长也会承认有浪费时间。
