Five main stalk crops planted in northern China including wheat, corn, broomcorn, soybean, and millet, were chosen to be the samples of the experiments. About seven morphological traits (such as plant height, ear length, ear weight, moisture content and so on) were measured in the crop mature period. The maximum shear force during shearing process, through static test equipment, at the second internode of the basal stalk, was recorded. And shear strength of each crop was calculated to find the differences of shear strength among different crops. The optimal regression models of shear force and morphological traits were obtained by multiple linear regression method with Statistics Analysis System. The equation based on the regression models was constructed.

Three types of base asphalt and six SBS were used to produce SBS modified asphalt. The interaction of SBS modified asphalt was discussed in different states between the base asphalt and SBS based on their compositions. Through the traditional tests, such as penetration, soften point and ductility, and US SHRP tests, the results indicated that influences to affect the temperature susceptibility, high and low temperature performance, aging characteristics are base asphalt, SBS types and their dosages. The functions of penetration to viscosity and complex shear modulus G~* to complex dynamic shear viscosity η~* were set up, and then theviscosity-temperature susceptibility of wide temperature span and the calculation method of low temperature viscosity were obtained."Process" evaluation criterions, high grading critical temperature T_ and low grading criticaltemperature T_ , were suggested according to the high and low temperatureperformances of SBS modified asphalt. Using the experience of Repeated Creep and Recovery Test for Binders, a new high-temperature evaluation index,modification rutting factor G~*~(-9) was obtained. The results after RTFO and PAV aging indicated that traditional tests didnt differentiate base asphalt and SBS modified asphalt, but dynamic mechanics temperature spectrum and G*-5 black chart clearly reflected the influence of aging to the SBS modified asphalt. With the IR and GPC tests, the reason of aging to the SBS modified asphalt were due to asphalt phase oxygenated and SBS phase depredated.

The shear layer vortices dominate in the initial portion of the jet, which are a result of the K-H instability. The crossflow encounters an adverse pressure gradient ahead of the jet and separates to form horseshoe vortices under the pressure downstream, and they develop into the wake. The wake vorticity comes into being in the actions of an adverse pressure gradient and a wall-normal component of vorticity, which originates from the wall boundary and is entrained into the jet. The shear layer vortices encounter adverse pressure gradients in the lee of the jet and break down, leading to the formation of the CVP and the CVP is the most important characteristic of the jet in crossflow.

文中指出：剪切层涡源于射流与横流之间的K-H不稳定性；马蹄形涡的产生是由于射流喷口上游迎风侧的壁面边界层内存在逆压梯度，使流动发生了分离，在下游逆压梯度的挤压作用下，形成了马蹄形涡，马蹄形涡向下游发展，进入尾迹区；在逆压梯度和法向涡生成项的共同作用下产生了尾迹涡，尾迹涡源于壁面边界层，止于射流，并将部分涡量向上输运至射流内部的CVP；CVP是横向紊动射流的重要特征，剪切层涡破裂后，在逆压梯度的作用下CVP形成。
