四川大学学报. 自然科学版, 1980 如众所知,单个守怛律方程的整体解理论已经发展得基本上令人满意了.为了构造其始值问题的整体解,人们先后提出或采用了有限差分法、粘性消失法、特征线法、光滑化方法、非线性半群方法等多种方法.从这些不同的途径,都成功地解决了非线性守怛律方程的Cauchy问题的整体解的可解性.但是,关于拟线性双曲型守怛律组的整体解的构造,目前仍处于探索阶段.截今,只在若干特殊情况取得成功,但已经获得的绝大多数成果,都是采用的Glimm方法 ...

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.

四川大学学报. 自然科学版, 2005 从云南邦拿掌温泉中采集样品,经过多次富集、筛选,最后分离出6株高温严格厌氧纤维素分解细菌.通过随机扩增多态性DNA(RAPD)分析,研究了这6株形态、生理、代谢特性相似的高温严格厌氧纤维素分解菌的遗传多样性,并根据实验统计数据作出6株菌的亲缘关系图.同时对产酶活性较高的B7细菌进行16SrDNA序列分析,确定了其系统分类地位.
