火山弹

熔岩以火山弹的形式落下，并累积在开口周围形成陡峭的圆锥。

The magma falls as volcanic bombs which accumulate around the vent and form steep-sided cones .

初步研究了火山弹的形成、空中飞行和落地变形的动力学过程。

Furthermore , the dynamics of formation , ballistic trajectory and colliding deformation of bombs is tentatively studied and discussed .

根据老黑山火山弹的分布情况，计算出了老黑山新期喷发时火山弹达到的高度范围。

According to the scale of the Laoheishan volcano and the distribution of bombs around it , t he range of height , at which bombs ascend , has been calculated .

然而，景点中有些火山构造的命名却存在着明显的错误，如：熔岩丘和增生熔岩球分别被错误地命名为“喷气锥”和“火山弹”。

Two volcanic structures , hornitos and accretionary lava ball , were wrongly named as " fumaroles " and " volcanic bomb " respectively in the Geopark .
