An oxygen-bubble and white-light speckle velocimetry method is presented.Instead ofpulsed laser and commonly used particle,a sheet like-bubble mass generated from anade wire byeletrolysing water is used as particle tracer,a white light flash set controlled by digital time delaycircuit is used as double pulsed light source,and 2-D velocity distribution in a sectional planewithin flow field can be obtained without using light sheet technique.

提出了一种氧气泡粒子白光散斑测速技术，与以往散斑测速方法不同的是，采用电解水时电解阳极丝上产生的氧气泡做为流场示踪粒子，用两个闪光时间间隔由数字延时电路控制的普通闪光灯做为散斑底片拍摄时的双脉冲光源，并且勿需片光技术，即可获得流场内部一个截面上的二维速度分布。

It shows that runoff is closely correlated with the features of individual precipitation, and it is also affected by vegetation within a short period of time. Raindrop erosion, sheet flow erosion and rill erosion on the slope are the main soil erosion patterns; sediment yield occurs mainly in flood season. Human activity and individual precipitation are two important factors that control the soil erosion at a small watershed. Comprehensive management on the slope in a small watershed is an efficient measure of water and soil conservation.

分析表明，小流域的产流方式容易随次降雨条件的变化而变化，植被因素在较小时间尺度内就会影响产流；产沙主要来源于坡面上的溅蚀、片蚀和细沟侵蚀，时间主要集中在汛期；人类活动以及次降雨条件是控制小流域侵蚀产沙的重要因素；在小流域内进行坡面的综合治理是水土保持的有效措施。

Shiv :- The most important part in work flow is the work flow logic is now in your work flow project and your business component are self contained and they are doing their own activity.

希夫： -在工作流最重要的部分是工作流逻辑现在您的工作流程项目和您的业务组成部分的自我控制，他们正在尽自己的活动。

Based on the Similarity principle of the fractal theory and on the quantitative analysis of the historical traffic flow measured on path network nodes through rough set theory,this paper discussed the mode structure of the real-time dynamic traffic flow and put forward the optimal control method.

The major implementations of the developed model include: Pseudo-spectral and finite-difference schemes are employed to approximate the spatial-differential operators in the horizontal and vertical directions, respectively. A second-order Runge-Kutta method is adopted to integrate in time for the velocity field and the free-surface elevation. The solenoidal condition of the velocity field is satisfied by solving the transformed pressure Poisson equation. A modified secant method is used to accelerate the iterative solution of the non-separable Poisson equation.
