The main idea is as follow: CAS scrambles service streams at head-end with pseudorandom sequence that control words produce. At the same time, Control words are transmitted to terminal for entitled terminal to descramble and entitled users to watch program.

数字电视条件接收总的思路是：在前端对节目流进行数字加扰，同时把加扰控制字加密后传到用户端，采用一定的策略使得只有授权用户才可以解密控制字，然后在控制字的作用下解扰器对授权用户的加密数据进行解扰，使其可以收看节目。

The results achieved by the unsteady simulation on the basis of Reynolds averaged Navier-Stokes are fitted to the experiential wind profile well. The results indicate that the numerical simulation based on CFD provides a new solution to study the downburst wind characteristics under the current conditions without detailed full scale data.

The commonly-used capacity calculation approaches for ramp junctions are mostly based on the American HCM method, It had been approved that the headways for vehicles following the Weibull distribution function at on-ramp junctions in urban freeway system. The paper examined the critical headway and following time by the modified drew method and the survey traffic flow data on-site. The gap-acceptance capacity calculating model was developed for on-ramp junctions of urban freeway, and the numerical integration method was used to solving the model. Finally, the capacity values were obtained in condition of different mainline design speeds and different acceleration lane lengths.
