Journal of Sociolinguistics, EarlyView.ABSTRACT This study investigates how ordinary Taiwanese netizens perform linguistic authority by policing others’ use of Mainland Chinese expressions in everyday online interactions not originally intended to be political and how such policing is subsequently supported, resisted, or (de)legitimized in the context of Taiwan–China relations.

Shuitu Baochi Xuebao, 2021 为系统评价黄土丘陵沟壑区在"退耕还林（草）"工程实施后不同退耕模式下的土壤水分涵养功能，选取0-200 cm土层的蓄水量、土壤含水量分层比、土壤水吸力和土壤含水量年际变化率作为土壤层水分蓄存、渗透、保持和稳定性的表征指标，分别对比了不同退耕模式下的土壤水文性质。结果表明：（1）各退耕模式下土壤蓄水量差异显著，撂荒模式的土壤蓄水量最高，为还灌和还乔模式下的1.6，1.7倍；（2）还乔模式下表层土壤水分的渗透性最优，深层土壤水分的渗透潜力最大；（3）各退耕模式的土壤持水性差异显著 ...

Shuitu Baochi Xuebao, 2021 为探究微塑料对土壤持水性能的影响，选用粒径为1 mm和25 μm的聚乙烯微塑料（PE—MPs）颗粒进行土培处理后，采用高速离心机法测得不同处理下的土壤水分特征曲线，并使用Gardner模型进行拟合分析。结果表明：（1）土壤中累积少量的PE—MPs （0~5.00 g/kg）能增强土壤持水性，但当累积量超过一定阈值（5.00~50.00 g/kg）会导致土壤持水能力显著降低。（2）1 mm大粒径PE—MPs大量积累对土壤持水性的降低效应更显著；25 μm小粒径PE ...
