The results showed that, whether early or late rice, biomass, accumula-tion and apparent utilizing rate of nitrogen were lower in RS/IS5.0 （40.0 cm ＆#215;8.0 cm） treatment, but yield of rice was higher in RS/IS2.0 （25.0 cm ＆#215;12.8 cm） treatment;grain numbers per spike of rice was more in RS/IS2.8 （30.0 cm＆#215;10.7 cm） treatment, and thousand-grain weight of rice was higher in RS/IS1.3 （20.0 cm＆#215;16.0 cm） treat-ment. For 4 varieties of early or late rice aforementioned, basal angle, opening an-gle and leaf area of 2nd leaf from top were larger in RS/IS5.0 treatment, and basal angle and opening angle were smal er in RS/IS2.0 treatment and leaf area smal er in RS/IS1.3 treatment.展开更多

Methods： DMRI were per- formed in 43 women with LABC （44 lesions, all were invasive ductal carcinoma） before, after the first and final cycle of NAC. Tumour volume, early enhanced ratio （El）, maximum enhanced ratio （Emax）, and maximum enhanced time （Tmax）, dynamic signal intensity-time curve were obtained during treatment. Residual tumour volumes obtained using DMRI were compared with pathological findings to assess the accuracy of DMRI. Results： After 1st cycle of NAC, the mean volume of responders decreased insignificantly, P 〉 0.05, but after NAC, mean volume of residual tumor decreased significantly （P 〈 0.01）. Morphol- ogy change： 29 cases showed a concentric shrinkage pattern while 7 cases showed a dendritic shrinkage pattern. Significant differences were found in El, Emax and Tmax between responders and non-responders （P 〈 0.05）. After 1st cycle of NAC, El, Emax and Tmax of responders changed significantly （P 〈 0.001）; while there is no significant change in non-responders （P 〉 0.05）. After NAC, dynamic signal intensity-time types were changed in responders, and tended to be significantly flat- tening, while no significant change was found in non-responders. The residual tumour volume correlation coefficient between DMRI and pathology measurements was very high （r = 0.866, P = 0.000）. Conclusion： DMRI is useful to evaluate the early response to NAC in LABC. The presence and volume of residual disease in LABC patients treated with NAC could be ac- curately evaluated by DMRI.展开更多

The palynofloras are dominated as follows： the Berriasian one by ferns （Cyatheaceae, Dicksoniaceae, Osmundaceae）, Classopollis and bisaccate pollen; the Valanginiar-Hauterivian one by ferns （Cyatheaceae, Dicksoniaceae）, Ginkgocycadophytus and bisaccate pollen; the Barremian one by ferns （Cyatheaceae, Dicksoniaceae）; the Aptian one by ferns （Cyatheaceae, Dicksoniaceae, Gleicheniaceae） and Ginkgocycadophytus; and the Albian one by ferns （Schizaeaceae） and bisaccate pollen. In the Albian the floral diversity raises with the angiosperms appearing.展开更多

The results show that they formed during the late Early Cretaceous. Geochemically,the volcanic rocks are relatively enriched in large-ion lithophile elements( Rb,K,and Th) and depleted in high field strength elements( Nb,Ta,and Ti),and rich in light rare earth elements,and depleted in heavy rare earth elements. The fact indicates that the main body of the volcanic rocks in the Qushenla Formation was derived from the partial melting of lower crust. The lithological assemblages are characterized by continental high-K calc-alkaline and shoshonitic series,suggesting that the southward-subducting oceanic slab in southern Bangong Lake had break off and that the Bangong Lake-Nujiang Ocean had closed before 107 Ma. The main dynamic mechanisms for the genesis of this set of intermediate-acidic volcanic rocks were upwelling of the asthenosphere and partial melting of the lower crust caused by slab break-off.展开更多
