ATS资源选择与配置的灰色局势决策模型

ATS研制的日益复杂精细化趋势使得测试资源的优化选择和配置问题也日益突出。针对传统方法存在不足,基于灰色理论和多目标多属性决策理论提出了一种快速、有效的资源选型决策方法:首先综合分析资源选择与配置的重要因素及测试属性,构建了灰色局势资源决策模型;然后通过对多个配置目标加权合成求解该模型,并利用属性权重进行二次决策,最后获得最优的资源选择与配置方案。工程实例分析表明,该方法科学可靠、可操作性强,能够有效解决ATS硬件集成中的测试资源选择与配置问题。

Discovery and character of the Kunlun-Yellow River Movement

Based on geomorphological, tectonic and sedimentary data, a Kunlun Yellow River Tectonic Movement has been recognized in 1 10-0 60 Ma B.P. This tectonic movement, which leads to uplift of the Qinghai_Xizang (Tibet) Plateau from 1 500 to 3 000-3 500 m, is periodic, abrupt and changeable in the movement rate of uplifting and slide slipping.     

Discovery of eclogite at northern margin of Qaidam Basin, NW China

Eclogite was first discovered at the northern margin of the Qaidam Basin in this study. It occurs as pods in the gneiss sequence of Middle to Upper Proterozoic age and is mainly composed of garnet, omphacite, phengite and rutile. The garnets contain 44%-62% of almandine, 15%-33% of grossular and 12%-30% of pyrope molecules, and the omphacites contain 40%-46% of jadeite. Applying garnet_clinopyroxene thermometry and jadeite geobarometry, the peak conditions of eclogite facies metamorphism occurred at about (722±123)℃ and at the pressure of up to c. 22 ×10 8 Pa.     

A recording phase lag between ocean and continent climate changes: Constrained by the Matuyama/Brunhes polarity boundary

The Matuyama/Brunhes polarity boundary (MBPB) is recorded in Chinese loess L8, which is associated with the glacial period. It is proved that loess L8 is capable of recording earth’s secular variation, and the lock-in depth in Chinese loess is no more than that of marine sediments. Comparison with the location of MBPB in Chinese loess and marine sediments, it is put forward that there is a recording phase lag between ocean and continent climate changes.
