在学习完凸透镜成像规律后,怎样利用这规律去解决与此相关的问题,特别是分析凸透镜成像时的动态规律问题,一直是学生学习的盲区,学生不能准确理解物体在运动时物距、像距、像
Curie temperature of amorphous alloys Co<sub>90-x</sub>Cr<sub>x</sub> Zr<sub>10</sub> decreases linearly with increas-ing x.Average magnetic moment per magnetic
Enrichment of massive graphite on lateral surface and evident macrosegregation alongboth longitudinal and axial directions were found by the influence of intens
本文对所有连通弦二部图是否是Ｈａｍｉｌｔｏｎ图进行了分类。并由此证明了Ｆａｕｄｒｅｅ猜想［２］对于弦二部图是正确的。
铝铸轧板坯晶粒度大的主要原因是，铸轧区偏大，冷却强度不够，浇注温度过高，供料嘴结构不合理等诸多因素引起铝水在结晶凝固时温度较高，冷却强度小，经过长期的实践，总结出了一些经验，以
The role of austenite in impact-abrasion process was studied on the basis of theimpact-abrasion test results of a newly developed austenite-bainitic ferrite dua
Impact toughness of ductile nodular cast iron loaded perpendicular to the austeniticdendrites is found to be 43% higher than that parallel to ones.Yet tensile s
本文通过讨论，证得，若Ｇ１．Ｇ２是交换格序群，ｆ是Ｇ１到Ｇ２是保持内在度量映射，则ｆ是Ｇ１到Ｇ２是群同态当且仅当ｆ（－ｘ）＝－ｆ（ｘ）。该定理部分解答了Ｅｎｄｒｅ ｐａｐ在文章《交换格序群保持内在度量映射》中提出的一个问题。
