| 1 | Carbon and Strontium Isotopes of Late Palaeozoic Marine Carbonates in the Upper Yangtze Platform,Southwest China显示文摘238 marine carbonate samples were collected from seven sedimentary sections ofthe entire late Palaeozoic (Permian, Carboniferous and Devonian) in the Upper Yangtze Plat-form, southwest China. Based on the absence of cathodoluminescence and very low Mn (gener-ally<50 ppm) contents of the samples, it is thought that they contain information on the orig-inal sea water geochemistry. The results of isotopic analyses of these samples are presented interms of δ13C and 87Sr/86Sr ratios versus geological time. The strontium data, consistent withother similar data based on samples from North America, Europe, Africa and other areas inAsia, support the notion of a global consistency in strontium isotope composition of marinecarbonates. The strontium data exhibit three intervals of relatively low 87Sr/86Sr ratios in thelate Middle Devonian to early Late Devonian, Early Carboniferous and Early Permian, corre-sponding to global eustatic high sea level stands. The lowest 87Sr/86Sr ratio recorded in theLate Permian was probably caused by substantial basalt eruptions in the Upper Yangtze Plat-form at the time. Three corresponding periods of relatively high δ13C values at roughly the samethe intervals were caused by a relatively high rate of accumulation of organic carbon duringsea level rises at these times. The deposition of coal was probably responsible for the increaseof sea water δ13C at other times. The δ13C values drop dramatically near theDevonian/Carboniferous, Carboniferous/Permian and Permian/Triassic boundaries, con-sistent with other similar data, which further support the notion that geological time boundariesare associated with mass extinction and subsequent rejuvenation. | Huang Sijing and Zhou Shaohua State Key Laboratory of Oil and Gas Reservoir Geology and Exploitation,Chengdu University of Technology, Chengdu, 610059, Sichuan, China Geological Institute, University of Copenhagen, Oster Voldgade 10,DK-1350 Copenhagen K,Denmark | 1997 | Acta Geologica Sinica(English Edition)1997,71,3: | 11 |

| 9 | Thermal Characterization of 1.3 μm InAsP/InGaAsP Ridge Waveguide MQW Lasers Based on I-V Method显示文摘An experimental way for the thermal characterization of semiconductor lasers based on I V method under pulse driving conditions has been developed, with which the thermal characteristics of strain compensated 1.3 μm InAsP/InGaAsP ridge waveguide MQW laser chips have been investigated. The results show that, by measuring and analyzing the I V characteristics under appropriate pulse driving conditions at different heat sink temperatures, the thermal resistance of the laser diodes could be easily deduced. The driving current and junction voltage waveforms of the laser chips under different pulse driving conditions are also discussed. | NAN K J, ZHANG Y G, HE Y J, LI A Z (State Key Laboratory of Functional Materials for Informatics, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 200050, CHN) | 2002 | Semiconductor Photonics and Technology2002,8,3: | 1 |
