According to the diwa theory created by Professor Chen Guoda, the characterisitcs of geotectonics and uranium mineralization in the diwa region of western Yunnan Province are preliminarily discussed. The sedimentary and magmatic formations and tectonic features indicate that the crustal structures in this region can be divided into three diwa structures. The Tengchong diwa system in the west underwent platform stage which was early in Lime and whose interval is longer. The Baoshan— Lancang geodome system and...

According to the diwa theory created by Professor Chen Guoda, the characterisitcs of geotectonics and uranium mineralization in the diwa region of western Yunnan Province are preliminarily discussed. The sedimentary and magmatic formations and tectonic features indicate that the crustal structures in this region can be divided into three diwa structures. The Tengchong diwa system in the west underwent platform stage which was early in Lime and whose interval is longer. The Baoshan— Lancang geodome system and Puer diwa system in the east underwent platform stage which was late in time and whose interval is shorter; but the Baoshan—Zhenkang geodome series is located at the margin of this region, and its geological characteristics have Probably a transitional nature. According to the time of beginning of the maximum-mobility period, they belong to the diwa of late Cathysian or Central Asia age. The Tengchong diwa system is similar to the Cathysian-type Fujian—Zhijiang pattern. The Puer diwa system is similar to Central Asia type diwa.The characteristics of uranium ore formation indicate that the economic uranium ore deposits are formed at the diwa stage. The polygenetic compound uranium deposits are very important in the Neogene basins. The uranium ore deposits are controlled by the factors such as the basement granites of the basins, the N-S trending regional faults, the melanocratic coal-bearing clastic rocks and the multiple cold and/or thermal water reworking. The development history of the diwa stage has a very important influence on the formation of the uranium ore deposits.At last, based on the summary of the diwa structures and uranium mineralization in this region, an attempt has been made to compare it with the SE China and North Xinjiang diwa regions in activation characteristics and uranium mineralization, indicating that this region may have a transitional feature and differ from them on diwa characterisitcs and mineralization.

本文根据陈国达教授创立的地洼学说,对云南西部地区的大地构造和铀矿化特征作了初步讨论。依据本区沉积建造、岩浆建造和构造特征:本区地壳构造可划分为西部的腾冲地洼系,转入地台时间早,间隔时间长;东部保山—澜沧地穹系和普洱地洼系,转入地台时间晚,地台阶段经历时间晚;但地处边缘的保山—镇康地穹列,地质特点可能有某些过渡性质,根据激烈期出现的时间,它们属于晚华夏或中亚期地洼。西部腾冲地洼系类似于华夏型的闽—浙式地洼;东部普洱地洼系类似于中亚型地洼。 该区铀成矿作用特征表明,铀主要在地洼期内形成工业矿床。新第三纪盆地中多因复成铀矿床很重要。铀矿床的形成受盆地基底花岗岩、南北向区域性控盆断裂、暗色含煤碎屑建造、多次冷水或(和)热水改造等因素控制。地洼阶段的发展历史对铀矿床形成有重要影响。 最后,在总结本区地洼构造和铀矿化基础上,进而与我国的东南地洼区及北疆地洼区的活化特征和铀矿化做了对比。表明本区无论在地洼特征上,还是成矿作用上与后两个地洼区不同,可能具过渡特征。

The hydrogen storage capacities and pressure-composition isotherms of TiFe + La and TiFe + Mm alloys were measured by exhausting water method. The effect of La and Mm on the activation characteristics of the alloys was studied. It was shown that the activation characteristics of the alloys could be improved greatly and the alloys were activated near the room temperature when the quantities of La or Mm in the alloys were greater than 4 wt% under our experimental conditions. However, La or Mm did not enter the crystal lattice of TiFe. They presented in the alloys in the form of a second phase to purify the alloys. The hydrogen storage mechanism mainly depends upon the intermetallic compound TiFe. The formation enthalpies of the hypothetical hydrides TiFeLa_yH_(1.0), were also calculated after Miedema's formulae and compared with the experimental results.

本文用排水法测量了TiFe+La及TiFe+Mm合金的贮氢量及坪台曲线。研究La及Mm对TiFe合金活化性能的影响。实验结果表明,当TiFe合金中的La或Mm含量大于4wt%时,就可以使合金的活化性能大为改善,使之在室温附近活化。La或Mm并没有进入TiFe晶格,它以第二相出现在合金中。La或Mm主要起纯化TiFe合金的作用。吸氢机制仍取决于TiFe金属间化合物。此外,我们还根据Miedema公式计算了TiFeLa_yH_(1.0)的形成焓,并与实验值作了比较。

Data of LaNi_5 are given here for comparison with that of MmNiAl and MmNiMn.

The crystal structures of MinNi_(4.5) Al_(0.5) and MmNi_(4.5) Mn_(0.5) and phase diagrams of their hydrides have been experimentally studied, and the changes of enthalpy of their hydrides △AH in hydrogenation processes have been plotted with different densities of hydrogen. Data of LaNi_5 are given here for comparison with that of MmNiAl and MmNiMn. The activation characteristic of Al-or Mn-substituted alloys has been improved in comparison with MmNi_5 and the plateau pressures oF MmNi_(4.5) Al_(0.5)-H system under varied temperatures have been found to be lower than that of MmNi_5-H, i.e., easy to dehydride and hydride,, and that of MmNi_(4.5) Mn_(0.5)-H system as well. Although their speed of absorption and desorption of hydrogen and their sensitivity of spoil are worse than LaNi_6's, MmNi_(4.)5 Al_(0.5) and MmNi_(4.5) Mn_(0.5) still have the latent capacity in industrial uses because of the merit of low cost and the fairly good hydrogen-storing ability.

本文研究了混合稀土镍合金(MmNi_5)在添加元素Mn,Al取代部分镍之后的晶体结构、F—C—T相图和生成热△H随贮氢浓度的变化规律。证实Mm Ni_(4.5) Al_(0.5)和Mm Ni_(47.5) Mn_(0.5)在不同程度上改善了富铈市混合稀土镍合金的活化特性,降低了坪台压力。与LaNi_5相比,它们虽然吸放氢速度和中毒敏感性都有所下降,但由于成本下降,而其它性能改变不大,故在工业应用方面有较大的潜力。
