The dynamic behavior of the granular soil in oscillation fields was studied through experiments. The tangency among the particles was measured by the electric resistance of coal particle specimens during oscillation to discuss the relationship among dynamic behavior of granular materials, the properties of particles(size and packing density) and the vibrating conditions(frequency and amplitude). It has been made clear that the inter-particle tangency depends not only on the acceleration of oscillation but also on the ratio of the particle size to the oscillation amplitude and that the electric measurement was available even to the coal specimen which was perfectly saturated with water.

通过试验研究了颗粒土在振荡场中的动力特性。通过测量煤粒样品在振动过程中的电阻来测量颗粒间的切线，讨论了颗粒材料的动态行为、颗粒的性质(尺寸和堆积密度)和振动条件(频率和振幅)之间的关系。结果表明，颗粒间切线不仅与振动加速度有关，还与颗粒大小与振动幅度之比有关，即使是完全饱和的煤样也能进行电测。
