Shuitu Baochi Xuebao, 2007 通过肥液间歇和连续入渗实验,分析了肥液间歇入渗土壤湿润特性。结果表明,肥液间歇入渗湿润锋运移速度较连续入渗慢,并随周期数的增加而减小;分析了肥液间歇入渗湿润锋运移的分段模型,提出了由连续入渗湿润锋运移参数计算间歇入渗湿润锋运移距离的简化模型,实例计算表明该方法简单有效;对比了肥液间歇入渗和连续入渗土壤含水量的分布,肥液间歇入渗土壤含水量分布较连续入渗均匀,相同深度土层中入渗水量占总入渗量的比例较大。

Shuitu Baochi Xuebao, 2021 为探索喀斯特地下浅层裂隙土壤水分运移规律，通过野外调查、单环入渗试验探索裂隙土壤的入渗特性及入渗模型的适应性。结果表明：（1）裂隙土壤初始入渗率为21.06~57.90 mm/min，入渗时间20~60 min后达到稳定入渗（4.21~13.69 mm/min），且入渗初期到最后的稳渗阶段存在着较大降幅（40.89%~89.08%），与非喀斯特地区相比，喀斯特裂隙土壤的入渗速率更快；裂隙土壤各入渗特征处于中等程度变异（变异系数为0.52~0.67）。（2）裂隙土壤各入渗特征与各土壤属性显著性相关较少 ...

Development of Time-series Osmotic Pump Sampler and its Application for Trace Metals Monitoring of Water System [PDF]
, 2016 随着工业化进程的日渐加快，水体中的重金属污染日益严重。监测水中的重金属含量对保护环境和人类健康具有重要意义。受各种自然或人为因素的影响，重金属在不同区域水体中的浓度存在较大差异，而即使是同一地点，也可能时刻发生变化。高时空分辨率的监测数据有助于更好地研究重金属的污染分布及其随时间变化的规律。 目前常用的水环境采样技术，如定时定点人工采样和薄膜扩散梯度（DGT）采样技术，时空分辨率低。渗透泵采样作为一种新型采样技术，可长时间在现场采集样品，得到布放期间内污染物的时间序列浓度，提高数据的时间分辨率。然而 ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

Shuitu Baochi Xuebao, 2023 坡度和作物生育期是影响坡耕地土壤入渗性能的关键因素,作物生长导致土壤特性及根系变化进而影响坡面入渗过程。通过人工模拟降雨试验,设计4个坡耕地坡度(3°,5°,10°,15°)及2个降雨强度(40,80 mm/h),在谷子4个生育期(拔节初期、拔节中期、抽穗初期、灌浆初期)开展试验,探究坡度和生育期对谷子坡耕地土壤入渗特征的影响机制,并结合入渗模型(Horton、Kostiakov、Philip模型)对谷子坡耕地土壤水分入渗过程进行拟合并评价其适用性。结果表明:(1)随坡度增加土壤入渗能力下降,与3°相比,

Analysis and Design of the Audit Daily Management System of the Electric Power Company of Jiangxi Province [PDF]
, 2015 现代信息社会对审计的冲击可谓是天翻地覆，国外先进的审计理论、技术和方式的大量涌入国内，审计数据正在成几何数量的增长，因此，数据日常信息的管理成为一个独立的业务来处理，需要大量的专业人员来处理相关事宜。信息化的高速发展对电网审计日常原始观念产生了巨大的冲击力，在形式和手段上都有所体现。形式上和手段上的转变，传统财务会计已经从纸制帐到转变成会计电算化，审计也相应从手工查帐到计算机审计。随着国家经济的发展，国家电网的飞速发展，伴随着基建项目的加速投建，因此，需要有大量的审计在建设过程中监督和指导 ...
