Research results show that the combined detecting system possesses fine pulse compression performance, range cut-offcharacteristic and the superiority which other radar signals are not provided with.
结果证明这种复合探测系统具有很好的脉冲压缩性能、距离截止特性及其它雷达信号不可替代的优越性。

Thus, materiality provides a threshold or cut - off point rather than being a primary qualitative characteristic which information must have if it is to be useful.
因此，重要性与其说是信息要成为有用所必须具备的基本质量特征，倒不如说是提供了一个门槛或取舍点。
