intermittent debris flow meaning in English

阵发泥石流

Cour and silting characteristics of debris flows - because of resistance decrease due to supernormal pore water pressure , intermittent debris flows can be accelerated on mild slope in the superimposable processes of several debris flows
?泥石流的冲淤变化特性?泥石流多阵迭加过程中出现超载孔隙水压力使龙头阻力降低，在缓坡上能够加速运动，说明泥石流龙头迭加具有加速效应。
And then the author established and verified an empirical equation for the ratio of the heights of collapsed part and running part for the avalanche soils , suggested the critical flow conditions of loose avalanche soils and block avalanche soils , discussed the causes of accelerated motion of consistent debris flows on mild slope , and studied the average velocity of intermittent debris flows
给出了判别崩塌土相对运动距离，即流高比公式，并用现场实测资料进行了验证。提出了松散崩塌土和块状崩塌土流动化的判别条件。探讨了稠性泥石流在缓坡上加速运动的成因，并讨论了阵性泥石流平均流速公式。
