The empirical results show that during the first period (1990-1996), Shanghai market did not exist volatility’s asymmetries that is receiving negative shock on the market is not different from the same degree’s positive shock, but different from shanghai stock market, in Shenzhen stock market the degree of receiving negative shock on market’s volatility is smaller than the same degree positive shock, which means the leverage effect exists in Shen’s market;
Objective:To study the effect of steroid and cyclophosphamide (CTX) intermittent intravenous pulse therapy on glomerular expression of C-C chemokines, monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1α and β (MIP-1α, MIP-1β), in patients with crescentic glomerulonephritis (CGN) to further investigate the underlying mechanism of the treatment.
Furthermore, we find that the money supply shock of M1 has the symmetric effects, while the money supply shock of M2 has the asymmetric effects, and the asymmetry is opposite to the western countries: positive money supply shock has significant effect to output, but the negative money supply shock has no significant effect to output.
The steady regime of this type exists and is stable.2.The anomalous regime (formally constructed) is characterized by a tendency for the shock to move toward the exit on increase of the static pressure at the channel exit.
It is shown that the realization of these solutions requires the bow shock to be perpendicular to the interface between the gases.
It is shown experimentally that these regimes coincide closely with the displacement of the normal shock to the nozzle exit and cessation of the emission by the jet of a discrete tone.
Increasing the force with which a shock discharged from the acts on an obstacle by way of converting a normal pressure shock to
Shadow photographs show that this is due to the reduction of the loss of total pressure in the flow because of the conversion of the normal pressure shock to a system of oblique shocks.
Eight sheep and eigat goats were iniured in BST-I biological shock tube in order to observe the effects of shock waves with overpressure duration prolonged and exposure repeated on the injury severity. It is found that the more the overpresure dration prolonged and exposures repeated, the higher the incidence and the severity of the injury are seen. It suggestes that overpressure duration and number of times of exposure have marked effect on the severity of injury above certain peak pressure.
Effects of thermal pollution on aquatic environment and abundances of five fish species by were analyzed. Frequent change in water temperature, temperature variations in both horizontal and vertical directions and the variation in aquatic community structure were observed. The main reasons for causing the changes in fish abundance and growth rate were found to be the increase in parasite infection rate, the endangerment of the cool-heat shock on fish embryo and the change in food value.
