- For instance, a particle at the outer edge of Saturn's B ring is in a 2: 1 resonance with Mimas, meaning that it goes around the planet precisely twice for each lap the satellite completes. 例如，土星B环外缘的粒子与土卫一周期成2：1共振，意思是粒子每绕行星两圈，卫星刚好绕一圈。
- This new moonlet, situated about 480 km (300 mi) inward from the outer edge of the B ring, was found by detection of its shadow which stretches 41 km (25 mi) across the rings. 这个新的小卫星,大约480公里(300英里)的内在的外围的B环,发现了它的阴影检测的41公里(25)在环。
- It b rings about bright future for the further development of portable signal collect ing analyzer. 经实践证明本系统是有效可行的 ,为便携式信号采集分析仪的进一步开发提供了光明的前景。
- Such gaps are present within Saturn's A, C and D rings, as well as throughout the Cassini division, a zone that separates the A and B rings. 土星的A环、C环与D环里都有这类环隙，隔开A环与B环的卡西尼环缝中也处处都是。
- Isoflavone derivatives with meta-substituent on B ring B环间位取代异黄酮衍生物
