Correctional checking formula of melt flow ratio in injection molding was obtained by introducing a correction coefficient β which reflected the complexity degree of mold cavity. The results show that, the maximum flow ratio of 486 can be obtained when injection pressure ranges from 150 MPa to 160 MPa in Archimedes spiral mold for PP, while maximum flow ratio of 419 can be obtained when injection pressure ranges from 160 MPa to 170 MPa for PE. There is a local fluctuation phenomenon for flow ratio and corresponding injection rate in square spiral mold when injection pressure of 100, 120 and 150 MPa for PP and 130, 140 MPa for PE are reached respectively,and this phenomenon is more serious for good fluidity of melt. The average flow ratio in Archimedes spiral mold is 6% larger than that in square spiral mold for PP, and 4% for PE, the average flow ratio of PP is 19% bigger than PE in Archimedes spiral mold, and 15% in square spiral mold. The influence of the cavity profiles on the melt flow ratio is more significant for good fluidity of melt.

The major achievement of this paper is: Based on characteristics of the traffic data distribution, execute pattern recognition operations on traffic condition on two dimensions by clustering, then use BP neural network to describe and forecast traffic flow aiming at each pattern. Making use of classic flow-occupancy inverse "V" model, implement polynomial fitting using least-squares algorithm and statistics method on flow curves to detect outliers which are proved to be not accord with practice through the actual implement, then use the moving average model to recorrect the outliers and absent. Make correlation analysis on muti-direction flow queues of the intersection and ones of upriver intersections, choose flow queue with high correlation as assistant one to improve the error tolerance of the prediction system, at the same time we can use the method to give an estimation of flow in intersection with out sensors. We design and implement an SOA(Service-Oriented Architecture)-based UTDD(urban traffic data mining development) with high expansibility and performance, which implement unified management and call of the data-mining application though defining a XML-based description of data-mining process and a common interface to call data-mining process, finally we build traffic flow prediction application model on UTDD.

Evidence suggests that 1 under more stable stratification, the basic flow, if moving faster at low and high levels (particularly in the presence of jets there), allows a resulting meso-β unsteady wave to propagate eastward with respect to basic flow and even at greater velocity compared with it; 2 vertical windspeed shear of basic flow causes instabilities of the TWT perturbation; 3 considering the second derivative of basic-flow wind with respect to z (denoted by zz≠ 0 which is simply given as β* hereafter) the expression for the phase velocity of vortex Rossby wave is obtained, which is unidirectional in propagation with respect to basic flow; 4 VRoW has its physical origin from β*, i.e., from z-varying heterogeneities of y-direction averaged vorticity of the basic flow field; 5 VRoW phase velocity is associated with zonal wave number k, its energy is dispersive and the group velocity exists in the x direction; 6 when windspeed meets the condition of β*, TWT disturbance instability may be that of mixed VRoW and gravity wave; 7 if basic flow is subject to linear shear but does not meet the condition of β*, the TWT instability is that of inertia-gravity wave.
