Bank collapse-landslide failure mechanism of typical reverse rock bank slope in Three Gorges Reservoir area [PDF]
At present, most of the reverse rock slope toppling instability failure is interpreted as a progressive overall instability failure controlled by dip angle and structural plane. However, the phenomenon of leading edge collapse is common in some reservoir

Composition Design and Welding Property Investigation of Some High Temperature Lead-free Solders [PDF]
, 2013 高温无铅焊料在电子封装中起着连接、导电、导热等重要作用。传统的高铅焊料中含Pb，而Pb对人类的身体健康和环境都有着极大的危害。因此，高温无铅焊料的研究已成为电子封装中的研究热点之一。目前，研究和开发高温无铅焊料主要采用尝试法来摸索最佳的合金成分，这不仅消耗了大量的人力和物力，且研发效率低，研发周期长。相图是材料设计的重要理论基础，在材料设计中发挥着重要的作用。它可以减少大量的高温无铅焊料的设计过程中的实验、减少设计开发成本。本论文对Cu-Ni-Sb合金体系的相平衡进行了实验测定和热力学计算 ...

Physiognomy Environment of the Ancient Routeway from Minzhong to Taizhong ——Concurrently Discussing the Existence of"Dongshan Overbridge" [PDF]
, 2008 晚更新世的最后一次冰期,当全球海平面下降到现海平面-50m左右,台湾海峡即消失。除了澎湖岛群东南部一片深海域仍为南海东北边一角外,闽-台之间成为一片洼地。这时,闽-台两地的居民互相来往已无天堑之隔,只有一条宽度不大的中心河道,渡过此河便可通达彼岸。本文全面分析了本区的自然条件、全球海平面变化和地貌冲淤环境之后认为:从福建的晋江向东,早期以航行,后来只过渡口,取道长元高地上岸可直通台中各地。这是一条便捷和安全兼备的古通道,是古人经过上万年的实践走出的一条传统的故道 ...
