Secondly, based on the microbeam analytical technique, on the one hand, through investigating the characteristic of major elements in the mantle minerals the author acquired the static information from mantle ; on the other hand, through multi - point analysis of a part of the minerals from mantle, the auther got dynamic information from mantle. finally, generalizating the fruits of this study and predecessors, the autor holds that the constituents of lithospheric mantle possibly includes spinel lherzolites, clinopyroxenites, websterite, dunite, harzburgites, garnet lherzite, phlogopite lherzite, eclogites, clinopyroxene megacrysts ; compared with east china and north china platform, the research field mantle shows the characteristics of higher degree of partial melting processes and more depleted mantle ; the. upper mantle beneath north hetian area is heterogeneous, with a tendency of deficit in a12o3 and lree from kaliyang in west hetian to the river basin of kalakshi river and yulongkashi river ; the subduction of the crust beneath north hetian has ever occurred in geological history and caused the mixing of mantle - crust ; the depth of the origination of basaltic magmas beneath north hetian exceeds 73km ; the thickness of the lithosphere beneath the research area amounts to 204. 9km ; the mantle beneath north hetian has geological condtions for forming diamond deposits
最後,綜合本區幔源礦物和地幔巖石的特徵以及地球物理資料,得出如下結論:本區上地幔的物質組成有尖晶石二輝橄欖巖、二輝巖、單斜輝石巖、純橄欖巖、方輝橄欖巖、石榴石二輝橄欖巖、金雲母二輝橄欖巖、榴輝巖;與中國東部以及華北地臺上地幔相比,研究區上地幔具有富集主

On the bases of the galaxy evolution theory, we use the therotical chemical evolution model of three zone ( such as halo, thick disk and thin isk ) and multi - phase ( diffuse gas, molecular clouds, stars of both low and high mass, the remnants ). by comparing with the observational constraints, such assurface densities, age - metallicity relation, g - dwarf metallicity distribution in the solar neighbourhood and the correlation between [ a / fe ] and [ fe / h ], supernovae rates, infall rates. the rationality of the model is verified. based on the theory model, we calculate the abundance of neutron capture element

These rivers have not shown such positive gains over the past two decades as those achieved by the rivers indus and beas. the pollution load of the rivers has certainly been significantly reduced as a result of the livestock waste control scheme and implementation of wpco controls after december 1990. however, large numbers of farms remain in the catchments of the river ganges, yuen long creek, the kam tin river and tin shui wai nullah
天水圍明渠及錦銹花園明渠的水質近年來並沒有像梧桐河和雙魚河一樣顯著地改善,雖然政府於1990年12月推行了禽畜廢物管制計劃及實施水污染管制條例,河道的污染量有所減少,但平原河元朗河錦田河及天水圍明渠集水區一帶尚有許多禽畜農場,加上區內不少鄉村尚未設有公共污水管道,因此污染問題並不容易解決。
