Shuitu Baochi Xuebao, 2022 为探究蓄水陶土持水能力及改良黄土高原土壤水分运移特性,进行了蓄水陶土持水特性试验及室内上覆蓄水陶土层的土柱入渗和蒸发试验。蓄水陶土设置3个粒径水平(20~30,5,2 mm),土柱试验上覆蓄水陶土层厚5 cm,并以不覆盖蓄水陶土的处理为对照(CK)。结果表明:室温15 ℃下,3种粒径的蓄水陶土40 s内均能达到饱和,且蓄水陶土吸水倍率介于30%~90%,同时释水速率较为缓慢,蓄水陶土持水性较好;就土柱入渗而言,不同粒径的蓄水陶土均显著促进土壤湿润锋运移距离,累积入渗量较CK处理增加40%~60 ...

法科学鑑定のための土壌試料のｽｸﾘｰﾆﾝｸﾞ -簡便な方法の組合せの有効性- [PDF]
, 2014 土壌試料の鑑定は多岐にわたる検査を必要とし､しばしば1つの事件で採取される試料が膨大な数にのぼることがあるので､迅速な鑑定のためには効果的なｽｸﾘｰﾆﾝｸﾞが望まれる｡火山灰土､沖積土､残積土など多様な土壌が分布する地域を選び､表層土から採取した73試料を用いて､土色の検査､粒径分析および粗砂の検査のｽｸﾘｰﾆﾝｸﾞ法としての有効性について検討した｡土色の検査は､風乾細土､湿潤細土､有機物分解処理後および脱鉄処理後の色の検査の組合せにより識別率を96.8%まで向上することができた｡粒径分析は ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Converting CO2 to CH4 under mild conditions is a promising strategy for solving environmental and energy problems, but also a challenge. In this work, the low‐temperature CO2 hydrogenation process over Ni/CeO2 catalysts was significantly accelerated by optimizing the H2 dissociation ability of Ni through the size effect, thus A‐Ni/CeO2 with an
