The effect on track of the deployed number of concrete sleepers within per kilometer are calculated and analyzed in detail based on the track strength theories(including static and dynamic) and the track stability theory, thus to find the theoretical base for the decrease of the deployed number of type Ⅲ concrete sleepers per kilometer.

Through calculating the harmonic currents of the compensating condensors branches which are mutual parallel in the substations, we can judge whether the harmonic resonates or not in different cases of parameter configuration, and then the theoretical basis will be provided for the suitable parameter configuration.

But in the aspects of confirming the parameters configuration of product,virtual prototype technology still has some drawbacks like high repetition and low efficiency.

To solve the problem of many initial parameters and configuration difficult in GA,the uniform design method is presented to optimize the GA’s control parameters configuration.

To solve the problem of many parameters and configuration difficult in MMAS,the uniform design method is proposed to optimize the parameters configuration.

A configuration parameter synchronization ap proach for master/slave station in environment on-line moni toring and control system;

As a result, the problems of configuration parameter of acquisition card should be solved.

This paper mainly introduces how to realize a FTP-based net service on LINUX operating system, and lists the detailed configuration parameters of relative servers.

A new operational method for mass customization-Need function development (NFD) according to the tree based two layer NFD model is proposed, and the conceptual model: including transmission function, need function and developing function is described.
