In the Triassic suture between the Sino-Korean and Yangtze cratons,the Qinling-Dabie metamorphic complex includes three tectonic units: a northern migmatitic terrane（ P < 20 kb）,a central UHP coesite- and diamondbearing eclogite belt（20;40 kb）,and a southern HP blueschist-eclogite belt（5;12 kb）. Protoliths include continental basement of late Archean to Proterozoic granitic gneiss complexes,and mid-to late Proterozoic bimodal volcanics,platform carbonates,and turbidite sequences including peraluminous sediments. Some early Paleozoic rocks are included as protoliths in the HP belt. The metamorphic complex is segmented into several large blocks by NE-SW trending faults. Three（ Dabie,Hongan and Wudan） occur in central China,and an eastern extension,the Su-Lu block is displaced to the north by the Tanlu fault. The UHP rocks are best exposed in the Dabie and Su-Lu blocks,whereas HP blueschists occur throughout the Hongan and Wudan blocks. Widespread occurrence of conjugate faults in the metamorphic complex suggests differential doming after tectonic juxtaposition of the UHP and HP units at shallow crustal levels. Eclogites of the UHP belt occur as blocks in ultramafic rocks,marble and gneiss and as thin layers interbedded with gneiss; some contain coesite and coesite pseudomorphs in garnet,omphacite,kyanite and epidote. Microdiamond inclusions in garnet have been reported. C-type glaucophane-bearing eclogites are restricted to the Hongan HP belt and contain paragonite instead of kyanite. The coherent HP terrane displays progressive zonation from transitional blueschist / greenschist,through greenschist and epidote amphibolite to eclogite assemblages. The UHP and HP belts possess similar metamorphic trends,deformation features and record clockwise P-T paths. Disposition of the UHP belt to the north of the HP belt,the northward increase in metamorphic grade,and the southward vergence of structures suggest formation during northward underflow of a microcontinent beneath the

通过镜检发现,川芎叶片在离体培养下的发育途径为形成体细胞胚。在体细胞胚的子叶、胚轴和胚根上,都可以继续产生次级胚状体,其中体细胞胚的胚轴上较早出现次级胚状体,而且数目也最多。次级胚状体的形成又影响了体细胞胚的成苗数。在相同的基本培养基上诱导体细胞胚成苗时,附加的激素组合中,由于细胞分裂素的种类不同,诱导产生的苗数及生物产量也不同,差异十分显著。光质效应与培养基中的激素组成虽有一定的交互作用,但在4种不同培养基上,除绿光对器官发生有明显的抑制作用外,其他光质对器官发生的影响无明显差别。

西天山造山带位于哈萨克斯坦—准噶尔板块与卡拉库姆—塔里木板块的结合部,是由一系列前寒武纪微陆块、古生代洋壳残片及陆缘弧相互拼贴而成的多聚合带、多成矿带,其独特的造山-成矿过程受到了国内外的广泛关注。本文通过构造单元划分与编图,建立了古生代西天山造山带的构造格架,认为古生代西天山造山带的构造演化依次经历了:罗迪尼亚大陆裂解与北天山早古生代多岛洋盆形成阶段(Z-O_2),北天山早古生代多岛洋盆闭合与南天山洋盆开始形成阶段(O_3-S),南、北天山洋晚古生代洋盆形成与发展阶段(D-C_1),南、北天山晚古生代洋盆全面闭合与天山碰撞造山带形成阶段(C1-C_2)和碰撞后板内演化阶段(C_2-P)。

A new oxygen-iodine medium gain model is developed to include pumping and deactivation of the upper laser levels of the iodine atoms, hyperfine and translation relaxation, as well as the flowing effect. The rate equations for gain of a supersonic flowing cw oxygen-iodine laser (COIL) are described when the medium is stimulated by a single-mode field. The general solution of the self-consistency integral equation is obtained. The result shows that the saturation behaviour in low pressure of the COIL differs from both the inhomogeneous and homogeneous broadening, and exhibits an "anomalous"saturation phenomenon.

In view of the large quantities of areas, complex landform and dynamic change of resources and environment in China, China has already funded abundantly a series of macro remote sensing investigation projects in land use/ cover change(LUCC) since 1990. Supported by the achievements of such projects, Chinese resources, environmental and remote sensing database (CRERS) was created. In this paper, we standardized the LUCC dataset of CRERS at scale of 1km, which facilitated the study of spatial features of LUCC in China. The analysis on the spatial features of LUCC and their causes of formation in China are based on the CRERS supported by the technologies of Geographic Information System (GIS). The whole research was based on the grade index of land use, ecological environmental index and index of population density. Based on the correlation analysis, we found that the special features of LUCC were closely related with those of ecological environment and population density, which resulted from that areas with better ecological environment and high production potential of land were easy and convenient for human being to live, which, furthermore, led to the aggravation of excessive exploitation of land resources there.

The chemical and physical properties of nitrogen and phosphorus as well as their concentrations in the over- lying water, pore-water and sediments in Huainan segment of the Huaihe river were analyzed. The chemical forms of phosphorus in sediments were differentiated by a sequential fraction method. The results revealed that the NH+4 -N content in pore-water of 6 surface sediments is obviously higher than that in overlying water, indicating that there is a dynamic tendency of releasing NH+4 -N from sediment into overlying water. Chemical compound of nitrogen differs among segments of the river, while phosphorus has no such difference. Calcium bound phosphate (Ca-P) and iron bound phosphate (Fe-P) accounts for 60 % of the total phosphorus, and occluded-P (O-P) accounts for less than 20 %. Our findings indicate that 1) industrial waste water and domestic sewage have contributed to the excessive nu- trient salts in Huaihe river, 2) decreased water flow during low water periods, and the interaction between sediments and overlying water disturbed by transport ships accelerate nutrient salt releasing into overlying water, which results in eutrophication of the river.
