The effect of concentrationprofile of key components in catalysts and temperature on internal diffusion efficiency factors were also discussed.
讨论了催化剂内部关键组分的摩尔分数分布情况及温度对内扩散效率因子的影响。

Therefore the dopant concentrationprofile measured by this method is a better approximation for practical carrier profile in silicon epitaxial layers.
因此，用此法测量的外延层分布是实际载流子分布的一种较好的近似。

Through the mathematical simulation of the velocity profile, the concentrationprofile and temperature profile, the correctness of the design criteria of furnace arch structure is testified.
