These results suggest that the diagenesis material of the Xiangshan volcanic intrusive complex was derived from crustal sources. The sources either had relatively lower maturity or had more juvenile mantle-derived igneous rocks than the exposed basement metamorphic rocks. Involvement of a small amount mantle-derived magma during the formation of the Xiangshan volcanic-intrusive complex was also possible. The diorite enclave, sub-quartzmonzonitic porphyry and lamprophyre were probably different mixing products between mantle and crust materals.

上述同位素示踪结果充分证实：相山火山-侵入杂岩的成岩物质主要为壳源，但与该区出露的基底变质岩相比，其物源区的成熟度相对较低或含有一定量的火成物质，并且不排除在其成岩过程中少量地幔物质的介入；闪长质包体、次石英二长斑岩及煌斑岩的成岩物质均含有一定量的地幔组分，可能为壳-幔混合作用的产物，只是受地壳物质混染的程度不同而已。

Bone marrow-derived mesenchymal stem cells are capable of chondrogenesis, making them a possible source of cells for injectable cartilage tissue engineering. There exist different ideas on the ability of mesenchymal stem cells's chondrogenesis in monolayer culture. Because of this, the effect of adult rabbit's bone marrow-derived mesenchymal stem cells chondrogenesis in monolayer culture was studied. The mesenchymal stem cells was isolated from adult rabbit's bone marrow and monolayer cultured. TGF-β1, Vit-C and Dexamethasone were used. Immunohistochemistry analyses and histological staining of H-E, Methylaniline blue and Alcian blue were performed to identify the expression of collagen type Ⅱ and cartilage associated matrix. The results showed that the induced cells expressed and produced collagen type Ⅱ and cartilage associated matrix. This suggests that the differentiation of adult rabbit's marrow-derived mesenchymal stem cells into chondrocyte in monolayer culture is feasible and may be induced by TGF-β1, Vit-C and Dexamethasone.

According to the energy conservation theory, BOM and CSIM4 were coupled. The BOM has no treatment on transmission solar radiation, which is of great importance when the model is adapted to Arctic Ocean. So the treatment was introduced to BOM. Through numerical test on different lead albedos, it was found that sea ice thickness is not so sensitive to lead albedo, which may be contribute to the lead occupies little ratio within multiyear sea ice pack. The reason of summer over-melt of arctic sea ice is the NCEP reanalysis downward solar radiation being larger than its reality. Then the arctic sea ice climate variability was simulated. Results showed that: simulated ice thickness change is in accord with the submarine investigated mean sea-ice draft changes. Simulated annually maximum ice thickness along the Eurasian continental oceans are closely related to the observed ones. The long-term mean simulated ice motion has the same features of the SSM/I derived ice motion. Sea ice extents in differential sub-regions have same trends comparing to the satellite passive-microwave data derived ones. Simulated ice concentration is closely related to the observed in the Arctic sub-regions. Sea ice flux through the Fram Strait involves ice concentration, motion and thickness. It is a composite criterion for sea ice model evaluation. The simulated ice area and volume export through the strait accord with the satellite derived or statistically reconstructed ones.(5) The simulated ice thickness climate variability and mean sea surface current of the coupled model were analyzed, results showed: the total ice volume in the Arctic Ocean has a significant decreasing trend. The volume variability is of a 10-year timescale oscillation, with two major periods of 12-13a and 18-20a. Mean ice thickness in the arctic sub-seas has different tendencies. It has an increasing trend in the Barents-Kara Sea and Baffin Bay-Labrador Sea, and decreasing in the others. The characteristic time scale of 7-10a wherein the river discharges leads the Fram Strait ice volume export is about the period that river water takes to be conveyed across the Arctic Ocean.(6) Using the simulated ice distribution in the Arctic Ocean and China precipitation, air temperature and SST in tropical key regions, the climate teleconnection were studied. Result showed: When the mean sea ice thickness is large in the central Arctic Ocean and Chukchi-Beaufort Sea , and small in the Barents-Kara Sea and Baffin Bay-Labrador Sea , the precipitation in South China, Tibetan Plateau, and the north part of Northeastern China are always smaller than normal, and v. v. When the mean ice thickness is small in CA, BC, East Siberian Sea and Greenland-Iceland-Norwegian Sea , and large in BL, The air temperature in north-eastern China, the southern of Tibetan Plateau, and Hainan Island, are always lower than normal, and v. v. In addition, when the sea ice is thick in BC and BL, the SST is larger in the middle and eastern Pacific Ocean, and is smaller in the tropical Southeastern Indian Ocean.
