What’s more, there is probably not enough conventional oil left to tip the climate over the edge.

更甚者，我们可能已经没有足够的传统石油将气候从危险边缘挽回了。

The piezo flexure also operates over a much wider frequency bandwidth than conventional systems incorporating a tip mass.

与使用末端质量的传统系统相比，压电弯曲件可在更宽的频带上操作。

The adoption of positive pre-swirl and low reaction degree increases the tip performance effectively, negative pre-swirl is required at hub for stator based on conventional design method;

在转子叶尖采用正预旋、低反力度的设计形式能有效地提高气动性能，如果想利用常规手段来设计下游静子则必须在叶根处引入反预旋；
