The dissertation analyzed the characteristic of the development of new high-tech industry at first. It pointed out that having characteristics such as high innovation and high risk, decides that the development of new high-tech industry needs the interference of government. Then, it analyzed the relevant theory of government economic functions and the particularity of the study during the development of new high-tech industry, pointed out the new high-tech industry even needs moderate interferes and supports of government. After that, draw lessons from the analysis train of the "diamond" theory of Michel Porter, it analyzed the demands of the development of new high-tech industry from the angle of catching up, include the regulation function that the key element disposes, demand regulation and preferential policy, strategical planning and organization coordinates, new high-tech enterprise hatches, and the supply of the legal system. Then it carried on international comparative analysis to the government economic functions of some typical countries, to find out the successful experiences with the lessons of the failure.

In this paper, the primary terms in closed form, which are essential to the influence of interference effects of the notches are obtained by means of the modification of body force densities, the adoption of local coordinates with respect to the center of each notch element and the decomposition of Melan's fundamental solutions. Thus an improved body force method is proposed for analyzing interference effects of random boundary notches subje-cted to complex loads.
