[交流] 【求助】求助一个单词！lateral crystal size

lateral size 或者是lateral crystal size，我不明白这指的是什么尺寸
背景是拉伸聚乙烯薄膜，应力诱导结晶，属高分子物理范畴。拉伸使长周期增大，在片晶之间的无定形区域产生伸直链针状晶体。退火处理两小时后，片晶的取向度和厚度都有提高。
例句：
Upon unconstrained annealing at 128C° for 2h, the film texture does not change, but the c axis orientation improves, the long period increases slightly to 48 nm, and the crystal thickness (along c) increases significantly to about 37 nm. The lateral crystal size also greatly increases (to nearly 40 nm), and the degree of crystallinity increases from 0.67 to 0.82.

while the breadth of the equatorial reflections increases, indicating a decrease in the lateral crystal size

The amorphous fibres in the AN films differ in lateral size, probably due to different local levels of stress and film thickness.

The crystal size is small, limited both by the lateral size of the fibres and the very high undercooling.
