Reverse traffic can lead degradation of TCP performance. To resolve this problem, we analyze the impact of reverse traffic carefully, and obtain the relation between reverse traffic and TCP performance. We propose an approach of rate control optimized for unidirectional trip time, and design an algorithm for rate control, called Unidirectional Trip Aware Rate Control, UTARC.

The boundary condition that the surface of the crust is kept at a constant temperature of 25℃, leads to relatively less obvious variation of temperature in the underground no deeper than 2 kilometers, so that the calculated strain rate is less than 10〓(normal geological strain rate is 10〓～10〓).

By comparing the electrodeposition rate and the particlesize of nanometer Ag film prepared by methyl sulfonic acid silver system with those of nanometer Ag film prepared by nitrate silver system under the same conditions, it is found that the particlesize of nanometer Ag film electrodeposited with nitrate silver is smaller and the growth rate of the nitrate silver nanometer film is faster. During the experiment, the silver grain was smaller and the distribution was more uniform in the nitrate silver electrolyte than in the methylsulfic silver electrolyte.

The results showed that the three straight lines model could fit the soil shrinking and swelling characteristic curves well. The characteristic values of the curves were smaller than 1. This indicated that during the processes of soil swelling and shrinking, the change of the soil specific volume was smaller than that of the soil water content. Values of the geometry factors of four soils studied were equal to 1 at the beginning of shrinking, less than 3 and greater than 1 at other swelling-shrinking phases. The geometry factor values in different phases showed that soil swelling-shrinking was anisotropic and only subsidence occurred at the beginning of shrinking.

结果显示：三直线模型能够很好地拟合4种土壤的收缩、膨胀过程；土壤收缩、膨胀曲线各段的特征值均小于1，这说明土壤胀缩过程中土壤容积的变化速率小于含水量的变化速率；4种土壤胀缩过程中几何因子r大于1而小于3，且收缩初期几何因子r等于1，表明土壤的胀缩是各向异性的，并且在土壤收缩的最初阶段只有垂直收缩。
