1Molecular organic geochemical evidence for paleoenvironmental changes at 11.87—12.28 m in GS-1 sedimentary core,Gucheng Lake,East China显示文摘Organic lipids with different occurrence modes in a sedimentary core in a subtropicalfreshwater lake, Gucheng Lake, were sequentially extracted, separated and analyzed. Thedown-core variations of OEP index of alkanes, C18:2/C18:0 ratios of fatty acids, ratios of boundfatty acids to free fatty acids, thermo-maturity indices of hopanoid hydrocarbons and relativeconcentrations of sedimentary minerals revealed an evident increasing in allochthonous inputfrom rock detritus below 12.28 m in the sedimentary profile. The distribution pattern of tightly-bound β-hydroxy fatty acids indicated a difference in bacterial communities above and below theboundary, as well as the gammacerane index may assign a significant change in lake watersalinity. The evidence, in general, suggested that a significant paleoenvironmental change hadtaken place in ca. 9.6 kaBP on the regional basis.Zhang, G Sheng, GY Fu, JM Wang, SM 1999Chinese Science Bulletin1999,44,15:15
2Eremophilane Sesquiterpenes from Cacalia Roborowskii显示文摘Four new eremophilane type sesquitopnes were isolated from the roots of Cacalia roborowrkii (Maxim) Ling. Their tricfores were eStablished as 8-oxo-eremophila-6. 9-dien-12-oic acid (1), 3β -acetoxyl- 8-oxo-eremophila-6, 9 -dien- 12 -oic aci (2), 3β-angeloyoxyl-8-oxo- eremophila-6, 9-dien-12-oic acid (3) and 3β -(2 -methylbutyryloxyl )-8-oxo-eremophila-6, 9-dien-12- oic acid (4) by means of iD and 2D NOR spectroscopy.Zhang, SM Zhao, GL Li, R Lin, GQ 1998Chinese Chemical Letters1998,9,1:5
3Diterpenoid Alkaloids from Aconitum Pendulum显示文摘A new diterpenoid 12 -epiacetyldehydrolucidusculline (1) and a new norditerpenoid alkaloid 2-hydroxydeoxyaconitine (2) were isolated from the roots of Aconitum pendulum, together with eight known alkaloids aconitine (3), deoxyaconitine (4), 3-acetylaconitine (5), 12-epiacetyldehydronapelline (6), dehydrolucidusculline (7), dehydronapelline (8), 12 -epidehydrnapelline (9), and noeline (10). The structures of the new alkaloids (1-2) were determined on the basis of spectral method.Zhang, SM Tan, LQ Ou, QY 1997Chinese Chemical Letters1997,8,11:5
4Interface Characterization of the SiCp/Al Composites Made by Powder Metallurgy显示文摘The interface of the SiCp/Al composites produced by powder metallurgy processing involving hotpressing above the matrix solidus temperature has been investigated by means of TEM. Several kinds of interfaces between the reinforcements and the matrix in the composite, including the clean interfaces, the faceted interfaces and the slight reaction intedeces, are presented. And most of interfaces belong to the slight reaction interfaces which are composed of the Al with different orientation from the Al matrix near the interface zone and particte-like substances produced by MgAl2O4 spinels andFan, JZ Zhang, K Shi, LK Zhang, SM 1999Journal of Materials Science & Technology1999,15,2:2
