Aerodynamicist Klaus Huenecke of Airbus has developed a “passive” scheme based on so-called designer vortices.

欧洲空中巴士公司的空气动力学专家辉奈克已研发了一个「被动」技术，以所谓的「订制涡流」为核心。

The key reason for the improved performance are the pairs of counterrotating swirls created at either side of the leading-edge bumps, called tubercles.

前缘能增进性能的关键理由，是因为在这节的，产生成对的反向旋转涡流。

When container with an inner aluminum-foil cover passes inductorium, heat will be immediately generated and makes the aluminum-foil layer stick tightly to the bottle mouth to avoid air leakage.

当装有铝箔内盖的容器经过感应圈时，即产生涡流瞬时发热，使铝箔面与瓶口紧密地粘合，达到气密封口的目的。
