英文摘要
An isotope ratio mass spectrometer will be purchased for use in ecological and environmental studies. Among the problems and systems to be probed are: sensitivity to change in arid land ecosystems; water source and humidity information and tree rings; carbon-13 and oxygen-l8 in modem tooth enamel; the history of atmospheric carbon dioxide; and carbon isotope ratio variation and stress tolerance in soybean.
