A method of feature selection based on tabu search is proposed for recognizing affective states （joy, anger, sadness, pleasure）. After combining with knear neighbour classifier, the tabu search heuristic algorithm achieved good recognition performance in the affective states classification , obtained the robust feature subsets which belong to 4 physiological signals （ECG, EMG, SC, RSP）. Simulation showed that it is feasible and effective to recognize emotion using tabu search algorithm.

The rate constant for the reaction of OH radicals and hydrogen sulfide (H2S) was studied in different bath gases (including N2, air, O2 and He) by using relative technique at 298 K. The small difference of the measured rate constants between N2 and those with the presence of O2 suggested possible influence of HS self reaction. Further experiments with NOx presence for scavenging HS demonstrated this assumption. The rate constant of (5.48±0.12) ×10-12 cm3 molecule-1 s-1 obtained with 4.09 ×10-4 mol m3 NO presence may be accurate for estimating the atmospheric lifetime of H2S. The results provided circumstantial evidence that the rapid reaction of HS with N2O is suspected.

The mass stream function of mean me-ridional circulation is calculated from the ECMWF andNCEP/NCAR reanalysis data sets using a superposi-tion computation scheme. The comparison of resultsshows that the common ascending leg of the Hadleycell calculated from the ECMWF data is strong andnarrow, and averagely lies more north of the equatorin comparison with its counterpart from the NCEP/ NCAR data, and furthermore the Hadley cell from theECMWF data shows an obvious double-layer struc-ture. Therefore, there are obvious differences be-tween Hadley cells displayed by the two objectiveanalysis data sets.

In the last few decades, the Late Paleozoic-Early Mesozoic tectonic evolution of South China has been quite controversial. The focus of debate is on both the age of ophiolites and the Late Paleozoic-Early Mesozoic geological and geodynamic environment. The Huaiyu Domain is located in the NE part of South China and exposes numerous significant geological features that are keys to understand the tectonics of South China. In this paper, we present some new evidence on stratigraphy, petrology and SHRIMP zircon U-Pb geochronology, and together with other geological and geochemical data available in the literature, and the following conclusions are suggested： 1） The eastern Jiangnan ophiolites belt, dated at 858±11 Ma by SHRIMP zircon U-Pb method, was generated during the Neoproterozoic, but not the Late Paleozoic; 2） The sedimentary rocks associated with these oceanic rocks do not contain radiolarians but Neoproterozoic acritarchs; 3） During Permian-Early Triassic times, the Huaiyu Domain was dominantly characterized by a shallow sea depositional environment since deep sea sediments are absent; and 4） The pre-Devonian tectonics of South China has been reworked by late polyphase tectonism through the Triassic and the Cretaceous periods. A Late Paleozoic-Early Mesozoic deep marine domain floored by oceanic crust never existed in the study area. The geochronological and structural data do not comply with a Late Paleozoic-Early Mesozoic South China Ocean.
