野生动物学报, 1988 有关成龄和幼龄麝鼠性别鉴定的报道屡见不鲜（华树芳,1985,刘桂仁,1984;曲增文,1987,李晓坤,1987）,其方法大同小异,我们亦采用其中的“看”和“触摸”法对成龄和幼龄麝鼠进行性别鉴定。但就仔鼠的性别鉴定至今尚未见报道。如能对仔鼠进行性别鉴定,对科研及生产会有重要意义。笔者通过1986 ...

The Research about Chinese Language Teaching Based on Language Learning Behaviors [PDF]
, 2016 近年来，课堂教学逐渐开始从传统的“以教师为中心”转向为“以学生为中心”的教学。汉语教学中，即使在同一个班级、环境、教师教学下学习，学习者的学习效率则不同。这差异的存在对学习者汉语学习水平产生了极大的影响。许多研究表明，学习者的学习还取决于学习者本人的学习行为，并强调学习者良好学习行为习惯培养的重要性。 本研究以语言学习行为为一个深入点来分析汉语教学情况，对学习者在汉语学习过程中表现出的学习行为进行探讨研究，并基于学习者的语言学习行为提出以学习者为主体的汉语教学建议 ...

间皮素、D2-40和Glypican3在卵巢肿瘤中的鉴别诊断意义
Zhongguo shiyan zhenduanxue, 2013 卵巢癌是第三大妇科恶性肿瘤,卵巢透明细胞癌临床较少见,约占卵巢上皮性恶性肿瘤的5%-10%,但在妇科病理鉴别诊断中却占有相当比例。与卵巢透明细胞癌相关的鉴别诊断包括原始生殖细胞肿瘤（特别是卵黄囊瘤和无性细胞瘤）及卵巢浆液性囊腺癌,卵巢癌的分类不同与预后及临床处理大不相同,需要更加客观的指标用来鉴别卵巢癌。本文的目的旨在mesothelin、D2-40、Glypican3在卵巢癌诊断和鉴别诊断中的作用加以探讨。
