Gongye shui chuli, 2023 电磁油水分离是一种新型环保高效的油水处理技术，在导电性油水处理方面表现出明显的优势，是目前的研究热点之一。基于胜利油田典型联合站采出液实测电导率，理论分析了油田采出液的电磁分离过程，并对不同含油量油田采出液的电磁分离过程进行了数值模拟和仿真分析；在此基础上结合油田生产过程，提出了电磁油水分离技术在油田中的应用方式。结果表明：油田采出液电磁分离具有超重力分离和气浮分离的优势，分离效率高；对含油104~105 mg/L的采出液，电磁分离可实现原油富集；对含油103 mg/L的采出液，电磁分离可用于回注水处理。

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1807-1820, May 2026.ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

Investigation and application of high strength profile control agent YTP(YTP高强度调剖剂的研究与应用)
Zhejiang Daxue xuebao. Lixue ban, 2001 分析了影响YTP高强度油田注水井调剖剂成胶时间的因素及其调剖机理.分析表明该调剖剂成胶时间可控、配制简单、方便（现场配制），动用设备少，成本低，对注水井管柱适应性强.室内岩心和64口井的现场试验结果表明：调剖剂对岩心封堵率高，承压能力强，调剖后在相同的注入量条件下，注水压力升高，吸水剖面得到有效调整，在相连通的油井见到明显的增油降水效果.

Eyes on nature: Embedded vision cameras for terrestrial biodiversity monitoring
Methods in Ecology and Evolution, Volume 15, Issue 12, Page 2262-2275, December 2024.Abstract We need comprehensive information to manage and protect biodiversity in the face of global environmental challenges, and artificial intelligence is required to generate that information from vast amounts of biodiversity data. Currently, vision‐based monitoring methods are heterogenous; they poorly cover spatial and temporal dimensions, overly ...
