查询词典 frequencies

However, at certain frequencies of oscillation, all the reflected waves are in phase, resulting in a very high amplitude standing wave.

然而，在某些振动频率，所有的反射波具有相同的位相，从而产生一个振幅很大的驻波。

Studies on impact-related minerals, geochemical anomalies, impact microspherules and microtektites enable us to define frequencies, magnitudes and types of impact bodies of extraterrestrial impact events. Impact layers and ejectas may not only provide distinct event markers in high-resolution stratigraphical correlation, but also potential interpretations for the catastrophic changes and their causes of life and global environment.

通过对撞击地层层序的时空变化、所包含的撞击成因矿物、撞击微球粒和微玻璃陨石以及古生物和地球化学异常等的研究，可以了解撞击事件的发生频率、幅度和撞击天体的性质等，也为探索生物和地球环境的灾难性变化及其起因提供了新的思路。
