原料（尘埃）正在被消耗的速率是研究电离气体地区和年轻恒星（黄/红扩展区域）来决定的。
The rate at which the raw material is being consumed is determined by studying ionized gas regions and the younger stars (yellow/red extended regions).
在来自星云中心蓝巨星紫外线辐射的压力下，这些由气体和尘埃组成的恒星形成区域尖端的电离氢分子将不复存在。
Ionized molecular hydrogen can be seen evaporating from the tips of these star-forming columns of gas and dust, under pressure of ultraviolet light from the nebula's central blue giant stars.
结果：淋巴结皮质的不同区域对高、低剂量电离辐射的敏感性均不同。
Results: the sensitivity to high and low dose ionizing radiation was distinct in different area of the cortex.
