表面上看似循环引用—t扩展经过t参数化的内容—实际上并不是真正的循环。
The seeming circular reference - where t extends something parameterized by t - is not really circular at all.
这些参数之间的变化关系符合直接碰撞导致非晶化模型，即每一个注入离子由于级联碰撞使表面局部的小区域非晶化。
The variation relations between these parameters are found to agree well with direct impact amorphisation model in which each projectileamorphises a logical region by cascade effect.
研究表明，分子体积、分子支链化程度以及分子表面的静电分布等定量结构参数可以有效地估算有机物的临界体积。
It was suggested that quantitative structure parameters or molecular descriptors can give effective prediction of the critical volume.
