The theory of high-strain dynamic testing of pile bearing capacity. The basic calculation expression of pile high-strain dynamic testing is rederived in a simple way, especially the semi-empirical analytical expression of wave equation . Besides, theoretically it has been proved that it's not necessary to have identic section hypotaxis along pile, and the application condition and reasonable operation have been pointed out. the CASE comprehensive method is suggested to replace the traditional CASE method. author has made a lot of improvement for the mathematical model of the matching analysis measured curves in the business software CCWAPC and scientific research software JXWAPC of which the author is in charge.

For such reasons, the author investigated comprehensively on cropping systems and agriculture development in Fenxin County from 2002 to 2004, using mathematics model and GIS, discussed the cropping systems characteristic and development orientation and optimized the cropping systems spatial distribution. The data were collected from literature, questionnaires to experts and farm households, on-site investigation and field experiments. The main results are as follows:1,Because of inconsequent exploitation and management of the resources, rapid increasing population in hilly region of red soil, the stress on soil, deterioration of farmland ecological environment and soil gleization become more and more serious. Natural features , water and thermal resources and species are abundance.

Secondly, in view of the identification problem after the change of MRAPC structure, the research has been extended to a kind of continuous system with time delay, and the robust convergence analysis for this model reference adaptive identification algorithm has been given. Using the intermediate value theorem in this analysis, the approximate problem in original analysis has been solved partly.

Firstly, several kinds of schemes were proposed according to the design demand. The best scheme was chosen after analyzing and comparing the schemes. The robot's structure was designed with Pro/Engineer and AutoCAD software. Secondly, the kinematics analysis conducted, coordinate transformation matrix using D-H method was set up, and the kinematics equation direct solution and inverse solution was deduced. The manipulative interface about the kinematics equation direct solution and inverse solution was completed with VC++ and the velocity Jacobian of displacement matrix was constructed using differential transform method. In the process of the trajectory planning based on robot's kinematics analysis, I propone a method by which we can get middle nodal point with normalizing factor in order to simplify our searching for these middle nodal points. In addition, I give these middle nodal points with actual physics signification. For eliminating contradiction between real-time and accuracy, I bring forward separately limit of error and reversal interpolation method. For decreasing calculation quantity, we resort to tri-spline interpolation in the articulation space.We analyse the work range of the robot by resorting to graphic means.

At the bookish assembly hosted by Secretary General Huang Chin-ying on January 3, Mr. Chang Pei-chen presented the first report on the Secrets of the 17-year Cicada written by Japanese Jin Yoshimura, a specialist of eco-mathematical model and biological evolution. The book was adapted from Yoshimura』s paper published in American Scientist in 1996, exploring the causes of evolution of magicicadas. Based on the duration of dormancy, magicicadas fall into two groups: the 13-year and 17-year periodical cicadas. Based on the principle of the survival of the fittest, as the lowest common multiple was larger, there were fewer groups proliferating at the same time to prevent damage of their ecological regularity as a result of hybridization.
