1. By adding steerable sidelobe dips and achieving high sidelobe falloff rate, the windows can be used to detect a weak signal with a strong signal nearby.
   只要在视窗里加上可指定位置的附叶洼沟和达到高的附叶衰减率，此视窗就能把在强信号附近的弱信号侦察出来。
2. By using the narrow-width approximation we find a sum rule for the decay rate of the string resonances with different spins at each mass level.
   藉著使用狭窄宽度近似，我们找到一个联加的规则可以计算衰变率与截面积。
