The interpolate algorithms of three-order NURBS curve and double three-orders NURBS surface are presented. The expressions of partial derivative and normal curvature of NURBS surface are derived by the theory of differential geometry. The geometric characteristics of different curvature area of the free-form surfaces are analyzed in detail. All these work lays a theoretical foundation for constructing the cutter location calculating model of free-form surfaces NC machining. 2 On the basis of analyzing the methods of cutter path generation, the standard of evaluating the various methods of cutter path generation is presented. The method of generating cutter path with constant scallop height is presented for the first time.

When treat-ing the spectra, transition, scattering problems, we must use the semi-microscopicapproach. The main new conclusions in this thesis are following:We found the different shrinking effect in ∧ hypernuclei and 〓 hypernuclei, the shrink-ing effect in ∧ hypernuclei are confirmed in a recent experiment;We also found a new approach to treat the configuration mixing of ∧∧ hypernuclei and〓 hypernuclei and that the conversion process may change the spectra and widths of〓 hypernuclei;For the first time, we investigate the neutron star matter without the ∑ hyperon butwith the new meson 〓(975) and φ(1020), we found the contribution of 〓 and φ canmake the equation of state of neutron star soften, and the maximum mass of neutronstar reduces;we extract a set of optimum parameters of the optical potential for the scattering of 〓with nucleus, we found that the 〓 nucleus optical potential need a bigger imaginarypart.

For the first time, we study the radio afterglow behavior during the trans-relativistic phase of the fireball shock wave. Considering the trans-relativistic shock dynamic and the synchrotron self-absorption effect of the relativistic electrons on the radio emission, we find that the dense medium model can not only explain the fast decline of the X-ray and optical afterglows of GRB980519, but also account for its radio afterglow quite well.

我们首次研究了致密介质情形下射电余辉在跨相对论阶段的行为，发现考虑到激波的跨相对论动力学和相对论电子的同步自吸收效应对射电辐射的影响，致密介质模型既可以解释GRB980519的快速衰减的X射线和光学余辉，也可以很好地解释其射电余辉的特点。

In l664 the great English diarist,John Evelyn,published,with the approval of the Royal Society of London,a book Sylva or a Discourse of Forest Trees in which one sees,perhaps for the first time,a realization that trees,then so important in the construction of ships,were indeed becoming sadly depleted and that something urgently needed to be done by way of deliberate planting to ensure enough for the future.
