灰分的碱度可能与纤维的细度有关。
More precipitation amount and rain days helped to increase effective stalks and fiber fineness.雨日和雨量较多能增加有效株数,提高纤维支数。
To a certain extent, the finer fiber fineness, the better sound absorption, and doesn effect obviously on the sound insulation.纤维细度变细,可在一定程度上提高材料吸声效果,但对材料的隔声量影响不明显。
