GIS overlaying analysis shows that, the spatial change of Minqin Oasis had the different characteristics in different stage in the last 50 years: at the end of 50's to the beginning of 70%, oasis expandation Was performed by extension of origin oasis; the atrophia of oasis from the beginning from 70's to the 80's was performed by increasing of non-oasis spot pieces of inner part for oasis; the main performance of keeping on expanding of oasis from late 80's to late 90's is outside extension of Baqu oasis near the upper stream, with increased oasis area in interior of hungriness and increased area of non-cultivation in Huqu oasis in the north. From 1998 to 2001, opening up wideness in interior of hungriness continued, but hnngrinessization of oasis became worse. The oases in the Minqin Basin developed from small to large and back to small in terms of area changes, and from south to north then to south in terms of spatial changes.

绿洲分布图的GIS叠加覆盖分析表明,近50年来民勤绿洲的空间变化在不同阶段有不同的特征:50年代末至70年代初,绿洲扩展主要表现为已有绿洲的外延式扩大;70年代初至80年代后期的绿洲萎缩,主要表现为绿洲内部非绿洲斑块增加;80年代后期至90年代后期的持续扩展,主要表现为靠近上游的坝区绿洲向外围扩展和荒漠腹地绿洲面积的增加,而北部湖区绿洲弃耕面积不断扩大;98年至2001年,绿洲荒漠腹地的开荒还在继续,但湖区的绿洲荒漠化还在进一步加剧。50年来民勤绿洲的发展总体上经历了一个面积由小到大再到小,空间位置上从南而北再向南的迁移过程。

The analysis of the high quality sand-body trap's characteristics suggests that large-scale traps include single large-sized sand-body trap and several overlaying small-sized lithological traps; furthersome reservoir facies involve fan delta, braided river delta and sublacustrine fan; the hydrocarbon enrichment usually forms in favorable reservoirs.

Based on the failure analysis of hot roll, this paper optimizedly adjusts alloy system and summarizes the experience of rolling wiresand improves ail processing properties. Then, it analyses the effects on some natural parameters such as alloy transfer coefficient, surfacing layers, welding current and arc voltage etc.. It confirms the fitting ageing technique. Also, it discusses the microscopic structural transformation back and forth ageing and the effects on hardness change of overlaying metal by some alloying elements including C, Cr, V, W, Mo, Ni, Mn, B, Re through OM, SEM and X-ray diffraction analyses. Finally the abrasive resistance, red hardness, thermal fatigue property and anti-high temperature oxidability are investigated in experimentation.

全文在热轧辊失效分析的基础上优化调整合金体系,总结了焊丝轧制的经验,改善各种工艺性能,分析了几个特性参数的影响,确定了适宜的时效工艺,并通过光学显微镜、扫描电镜和X-射线衍射对时效前后的显微组织转变以及部分合金元素如C、Cr、V、W、Mo、Ni、Mn、B、Re对堆焊层硬度变化的影响进行分析,最后通过试验考察了堆焊层金属的耐磨粒磨损性能、红硬性、耐热疲劳性和抗高温氧化性。
