Abstract: 采用化学水浴法制备了ZnS薄膜,并从沉积ZnS薄膜的化学反应原理出发,对其结构和性能进行了综合研究。结果表明:随着沉积时间的增加,ZnS薄膜厚度增加,其光学透过率降低,薄膜的禁带宽度也随之变小,最小值为3.74 eV;而薄膜的粗糙度变化不大,其值在6~9 nm之间。随着反应物浓度的增加,薄膜的光学透过率呈先增加后减小的变化,当反应物浓度过低或过高时,沉积反应都会向同质反应偏移,在薄膜表面生成杂质,导致薄膜不均匀。当沉积时间为120 min,ZnSO4、SC(NH2)2和NH3·H2O的浓度分别为0.03、0.4和4.0 mol/L时,沉积的ZnS薄膜呈均匀致密结构,成分为单一ZnS相,其光学透过率在450 ~ 900 nm波段高于70%

Abstract: 使用中频磁控溅射法制备了具有光学减反射与电学钝化的复合功能的氮化硅(SiNx)薄膜,并对其结构和性能进行了综合研究。结果表明:在常规制绒硅片上沉积的两种不同折射率的单层SiNx减反膜表现出优异的光学性能,其在300~1 100 nm波段的平均反射率由镀膜前的14.86%下降到镀膜后的5.50%和6.58%;若采用多层的氮化硅(m-SiNx)+ 氮氧化硅(SiOxNy)薄膜作为减反层,则其平均反射率进一步下降到4.03%。同时,优化工艺制备得到的掺氢氮化硅(SiNx∶H)薄膜,表现出良好的电学钝化特性。试验中分别制备了两种复合结构的薄膜,即SiNx∶H(厚度15 nm) + m-SiNx+ SiOxNy与SiNx∶H(厚度30 nm) + m-SiNx+ SiOxNy复合薄膜,其平均反射率分别为5.88%和5.43%; 把这两种薄膜用于晶体硅太阳电池上,其开路电压则都达到了575 mV,表现出良好的性能

Abstract: Guided by the idea of "tectonic-controlled basin, basin-controlled sedimentary facies, sedimentary facies-controlled source-reservoir-cap assemblage" and the principle of "process-response", namely that the basin is formed by crust-mantle coupling, plate activation and tectonic movement, and the space-time distribution of the sedimentary sequence and the facies zone association is formed by the sedimentary and filling processes of basin, while the configuration of sedimentary sequence of different orders, the superimposed pattern of system tract and the space-time association of facies zone are closely related with the sedimentary filling process of basin. On the basis of many research and exploration results of the Middle and Upper Yangtze cratonic basin made by previous research findings, it is thought that further study on sedimentary environment, sequence configuration and the filling process of sedimentary and so on, are significantly important to deepening the understanding and oil and gas resources exploration of the researched area. Therefore, relied on the sedimentary response records of the profile configuration of sedimentary sequence, the superimposed pattern of system tract and facies zone association, the sedimentary filling process of basin can be effectively revealed by analyzing the temporal and spatial variation law of these records. Specific technical route is that the tectonic-sequence (second-order sequence) that indicates the overall characteristics of basin is considered as the basis, the sequence stratigraphy (third-order sequence) that indicates the filling framework of basin is taken as the research unit. Meanwhile, the sequence configuration, superimposed modes (above fourth-order sequence) and the distribution pattern of facies belts are taken as the research objects. Based on the division of the type and evolutionary phase of Middle and Upper Yangtze cratonic basin in Caledonian Period, this paper has analyzed the sedimentary filling process of typical basin, discussed the filling characteristics of sedimentary sequence and its difference and established the sedimentary evolution model in stages. It is found by the study that the Middle and Upper Yangtze craton in Caledonian Period is composed of two sedimentary system tracts including intracraton and craton-margin and the basin undergoes two evolutionary phases that change from extension mechanism to compression mechanism, which are composed of three stages of sedimentary filling processes including rift valley type basin, chasmic basin and depression basin. Generally, the Caledonian cratonic basin under different evolutionary phases or the basin of different types under the same evolutionary phase has different sedimentary responses including sedimentary formation type, sequence configuration and superimposed pattern of system tract, which indicates the distinguishable sedimentary filling characteristics and obviously different controlling factors. In a word, the co

Abstract: In tokamak plasmas, the discharge will turn into "runaway" discharge if the density decays to a critical one. The discharge will enter into "slide-away" discharge if the density reaches a lower level. The slide-away discharge is characterized by high confinement of superthermal electrons which constitute a large part of plasma current. In HT-7 Tokamak, the slide-away discharge is achieved by reducing the plasma density. The relationship between plasma current and critical density of slide-away discharge is investigated. It is also find that the increase of density in slide-away discharge can make the confinement of superthermal electrons poor and lots of superthermal electrons lost from the vacuum chamber.

Abstract: The hydrocarbon breakthrough in the 4th member of the Leikoupo Formation shows important geological significance for petroleum exploration. Through comprehensive analysis of drilling cores, thin section, well logging data, fluid inclusion, carbon, oxygen and strontium isotope, three types of paleokarstification, including syndepositional, epigenic, and buried ones, are identified in the residual deposits under the unconformity surface at the top of Leikoupo Formation. They are considered as the key factors that control the reservoir formation of the 4th member of the Liekoupo Formation. The distribution of the reservoirs formed in the early stage is controlled by syndepositional paleokarstification. These reservoirs are limited in lateral by distribution of high-energy beach facies. Epigenesis paleokarstification is a critical geologic event that leads to the formation of the reservoir. The related reservoirs are vertically limited within 90m below the unconformity surface. Based on vertical and lateral distribution patterns of weathering karstification, it is suggested that karst-related reservoirs are commonly occurred vertically in debris-support breccia limestones and dolostones that distributed within surface karst area, or along half-filling high-angle dissolved seams and in small to medium-sized solutional pores in the vertical direction, and half-filling small to medium-sized solutional pores, dissolved seam, broken crack in the cave top and river breccia. Laterally, these reservoirs generally developed at karst slope, and karst hammock are found as the most advantageous geomorphic units for the formation of reservoirs. Burial karstification is related with dissolution of barbonte minerals resulted from hydrothermal fluids and organic acid, and it is considered as the key factor for reservoir optimization.

Abstract: The effects of different planting densities and modes on grain yield and physiological parameters of two summer maize varieties ("Zhengdan 958" and "Xundan 20") were studied under high yield conditions in North Henan Province. With 67 500~ 90 000 plants per hm-2, D1 protein content, optimal photochemical efficiency of PSII (Fv/Fm), photochemical quenching coefficient (qP), photosynthetic rate (Pn) and activities of foliar superoxide dismutase (SOD) decreased. However, peroxidase (POD) activity, non-photochemical quenching (NPQ) and malondialdehyde (MDA) content increased. At the same time, bald needle length increased and ear weight decreased. Yield increased to a peak then decreased with increasing plant density. When plant density exceeded 82 500 plants per hm-2, Fv/Fm, qP, Pn and SOD activity decreased dramatically. These parameters were lower at densities of 90 000 plants per hm-2 than at 82 500 plants per hm-2; dropping by an average from 1.2%~21.7%. NPQ, POD activity, and MDA content increased with increasing plant density. These parameters were also higher at densities of 90 000 plants per hm-2 than at 82 500 plants per hm-2, increasing by an average 3.2%~15.0%. Fv/Fm, qP, Pn and SOD activity in wide-narrow row planting mode were higher than in equidistant row planting mode, while NPQ, POD activity and MDA content exhibited the polar opposite. When the density exceeded 75 000 plants per hm-2, Fv/Fm, qP, Pn and SOD activity in "Zhengdan 958" were higher than those in "Xundan 20", but NPQ, POD activity and MDA content exhibited the polar opposite. D1 protein content, Fv/Fm, qP, NPQ, Pn, activities of SOD and POD, MDA content, bald needle length, ear weight and yield were significantly influenced by variety, plant density and planting mode. The interactions of the three factors were distinctively significant. Yield was highest at a density of 82 500 plants per hm-2 in the wide-narrow row planting mode for the two summer maize varieties.
