1·It has also produced odd landscapes of precarious mesas that would have toppled centuries ago in worlds with standard gravities.
低重力也构造起奇异的地形。若是换在标准重力的星球，这里危险的台地在数个世纪前就早已坍塌了。
2·The comparability of opposed-flow flame spread over thin solid fuels in finite spaces in different gravities was numerically simulated.
利用数值模拟方法，研究了不同重力下有限空间内薄燃料表面逆风传播火焰的相似性。
