In the Dabie high pressure (HP) and ultrahigh pressure (UHP) metamorphic belts, eclogites can be divided into two types, HP eclogites (or cold eclogite) and UHP eclogites. HP eclogites occur in the southern Dabie Mountains and are characterized by the presence of glaucophane. The primary mineral assemblage of the eclogites is garnet, omphacite, phengite, epidote, glaucophane, quartz, zircon and rutile. Garnet contains abundant mineral inclusions, and exhibits apparent compositional zoning with dramatic increases in MgO and decreases in MnO from core to rim. The PTtD path indicates that supracrustal rocks were metamorphosed and deformed from epidote amphibolite to eclogite facies by subduction and collision, then uplifted to the upper crust by thrust faulting in a continuous plate convergence and reworked by retrograde metamorphism of epidote amphibolite facies and by ductile deformation. The HP metamorphic rocks were uplifted to the surface, and modified by greenschist retrograde metamorphism and ductile to brittle deformation in an extensional environment. Fluid inclusions, melt inclusions and fluid bearing minerals indicate that fluid melt rock interaction was widespread in the eclogites. Partial melting occurred during the HP metamorphism, but the migration of melt was limited, and thus magma activity was very limited. Secondary fluid inclusions are abundant in the eclogites of the Dabie Mountains. They are mainly H 2O and CO 2 rich, and halite bearing multiphase fluid inclusions. Primary fluid inclusions have not been found, possibly because rapid uplift caused decrepitation of high density inclusions.

This review introduces the history and present status of data envelopment analysis (DEA) research, particularly the evaluation process. And extensions of some DEA models are also described. It is pointed out thatmathematics, economics and management science are themain forces in the DEA development, optimization provides the fundamental method for the DEA research, and the wide range of applications enforces the rapid development ofDEA.

The rigorous proof of the relation det is given. This relation has been used to obtain the exact critical surface and the correlation length exponents of the one-dimensional directed bond percolation problem with bonds connecting 1～Lth nearest neighbours. A（L） is related to the transfer-matrix by （7）. qi is related to the occupation probability of the i-th nearest neighbour bond pi by qi=1-pi （i=1, 2, ..., L）. fL is a multi-varlable polynomial in q4’s.

The expanded area and structure of urban lands and landscape features in ürümqi City are analyzed using RS and GIS means based on the MSS image in 1975 and the TM images in 1990, 1999 and 2002, as well as other related maps. On which the scale, intensity and spatial differentiation of the expansion of the ürümqi urban area during different periods are lucubrated. The results reveal that urban expansion was rapid during the periods of 1949―1965 and 1975―1990, and that it was stable after the 1990s. The urban expansion pattern was significantly different during different time periods: the urban area was expanded outwards based on old districts in a spanned development pattern during the period of 1949―1965; development was stagnant during the period of 1965―1975; urban expansion developed mainly in old districts in a grouped way during the period of 1975―1990. The trend of urban expansion along the traffic lines was obvious, and the direction of urban expansion was dominated by the south-north zonal expansion and supplemented by east-west axial expansion; urban expansion reached the development stage of "multiple centers and multiple districts" after the 1990s, and urban networks were developed more precisely after this time. The sources for urban expansion were mainly cultivated lands, grasslands and unused lands; during urban expansion, the land area devoted to traffic lines, residential areas, dispersive industrial and mineral areas, and garden plots was rapidly enlarged.
