Taking the project as an example, the main points of the design were put forward from several aspects such as cross section choice, traffic node treatment, roadside large scale public building traffic organization, the existing roadbed and pavement strengthening, greening & lighting, etc.

Due to the BT was designed for transferring general big file,its piece selection algorithm is not suitable for transferring media file.

In this paper, negative selection algorithm for artificial immune system (AIS) is improved by adopting genetic algorithm, in which Euclidean distance is selected as fitness function, to generate detectors (antibodies).

The effect of crystal plane selection of diamond cutting tools on cutting process and perfomance of cutting tools was studied from the viempints of coefficient of friction between diamnod too and work piece material, tool wear and micro-strength of the cutting edge.
