"We're focusing on observing and understanding earthquakes in space and time and on developing methods that use patterns of small earthquakes to forecast larger ones," Rundle said. “我们从空间上和时间上来观测和预测地震，通过研究震级低的地震来预测震级高的.
The thermal relaxation time of small drops and particles in air is quite short. 空气中小水滴和粒子的热张弛时间是非常短的。
The Field ionization and Coulomb explosion of small molecules in intense femtosecond laser pulses was studied by using the time of flight mass spectrometer. 摘要利用飞行时间循谱仪和飞秒泪光放大系统，对分子在飞秒强镭射脉冲作用下的场致电离和库仑爆炸过程迸行了研究。
It was a time of great tribulation. 那是一段充满苦难的时期。
The comparison shows that the new method is more effective and accurate than Sabine's equation in calculating reverberation time of small enclosures. 在算例部分，计算了一矩形封闭空间内的混响时间，通过与实验结果进行比较，验证了这一方法的正确性。
