stealthier

Labour's move to raise revenue by pushing up payroll contributions, a stealthier tax than most, had little to commend it.

工党在此方面没什么值得称道的，他们通过提高工薪缴费——最见不得人的税种，来扩大税收。

Now Mr Blue is showing off a jet-powered, stealthier version, called the Avenger.

现在，布鲁先生正在展示一款以喷气式发动机为驱力、隐形机能更佳的无人机，名为“复仇者”。
