从波动理论的角度研究小爆炸波群的产生机制。我们看到所获得的地震记录中主要的所有波都是某种表面波，尤其是色散瑞利波和 SEZAWA 波。这些波群被证明满足本文在理论上建立的四分之一波长定律。由于表面层的屏蔽作用，不能生长很多种表面波群。这使得我们的地震图相当简单。在地震勘探中，本文研究的表面波至少在某些情况下可能有用。
Generation mechanisms of wave groups by a small explosion are studied from a wave theoretical point of view. We see all waves predominant in the seismic records obtained are some kind of surface waves, especially of dispersive RAYLEIGH and SEZAWA waves. These wave groups are shown to satisfy the quarter wave length law which has been established theoretically in the present paper. Owing to shielding effects of a superficial layer, not very many kinds of surface wave groups can grow. This makes our seismograms rather simple.In seismic prospectings, the surface waves studied in the present paper may be useful, at least, in some cases.
