International Journal of Applied Linguistics, Volume 36, Issue 1, Page 322-335, February 2026.ABSTRACT Most research into the relationships of linguistic complexity and accuracy to functional adequacy has focused on either spoken or written mode. The current study extended previous studies by investigating these associations across both modalities and how the nature of these relationships was influenced by learners’ L2 proficiency and task type.

Shuitu Baochi Xuebao, 2006 流域地貌形态科学、准确和综合量化成为建立具有广泛适用性的流域土壤侵蚀预报模型的关键科学问题之一。分形理论的提出为流域地貌形态定量研究开辟了新的思路。本文依据分形理论，在建立小流域概化模型基础上，采用模拟降雨试验、高精度摄影测量和GIS技术，对流域模型地貌形态分形特征与侵蚀产沙定量耦合关系进行了研究。结果表明，基于消除了降雨特征影响的相对输沙率，可将流域模型侵蚀产沙过程划分为初期、活跃期和稳定期3个阶段；在不同侵蚀产沙时段，流域模型地貌形态分形信息维数Di呈现与相对输沙率Sr基本类似的变化趋势 ...

Design and Implementation of License Plate Localization System Based on Adaboost [PDF]
, 2016 摘要 论文论述了车牌定位系统设计与实现的方法和过程，车牌定位是车牌识别系统中车牌定位、车牌分割、车牌号码识别三部分的第一个部分，好坏直接关系到整个系统识别率的高低，并且对识别速度有很大影响。 本文在理论研究上主要包括特征提取、算法选择、算法改进三个方面。在充分研究和理解Haar特征的基础上，提出了“回字形特征”和“非对称线性特征”两种类Haar特征。设计过程中选取四种原有Haar特征及本文提出的两种类Haar特征的六种特征为特征模版，以及对窗口大小和移动步长的优化选取生成了5571个特征 ...

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 522-539, February 2026.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

Zhongguo shiyan zhenduanxue, 1997 为鉴别血尿来源，提高对血尿出血部位的诊断率，本文用Ｔａｍｍ－ＨｏｒｓｆａｌＰｒｏｔｅｉｎ（ＴＨＰ）抗体免疫染色法观察了１４８例血尿中红细胞表面ＴＨＰ含量，同时与红细胞形态学法进行了对比。以肾小球血尿（ｎ＝６９）ＴＨＰ染色阳性率大于７０％，非肾小球血尿（ｎ＝７９）ＴＨＰ染色阳性率小于３０％为标准，正确符合率为９５．３％，形态学检查的正确符合率为８９．９％；ＴＨＰ法检出阳性率高于形态学法（Ｐ＜０．０５）。因此认为，ＴＨＰ免疫染色法能较特异地鉴别血尿来源，是一种血尿定位诊断的较好方法。

Studies of cerebral venous circulation and coagulation function in patients with aneurysmal subarachnoid hemorrhage [PDF]
, 2016 目的：1.利用全脑血管造影技术(DSA)和磁敏感加权成像(SWI)观察动脉瘤性蛛网膜下腔出血(aSAH)患者脑静脉循环的变化，并探讨其对患者病情的判断价值。 2.利用血栓弹力图(TEG)研究aSAH患者凝血功能的变化，旨为评估患者凝血及纤溶系统的改变提供新的思路。 方法：1.收集南京军区福州总医院57例aSAH患者、48例未破裂动脉瘤患者及45例非动脉瘤患者(正常对照组)，利用DSA观察并比较三组患者脑微循环时间(mCCT)及脑静脉循环时间(vCCT)及脑微血管及皮质静脉的显影特征。 2 ...

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 916-926, February 2026.ABSTRACT This study explores how multimodal input modes affect young EFL learners’ incidental collocation learning performance and experience. A total of 97 EFL learners (aged 12–13) in a Chinese secondary school were randomly assigned to two multimodal groups (reading‐while‐listening and viewing‐with‐captions) and a reading‐only group (as a control ...
