  4. In chapter 1, we briefly reviewed the risk theory and its development. and the significance about this paper was expressed. in chapter 2, we introduced classical risk model. in which, making this risk process into a strong markovian process is the preparation of deriving the main results. chapter 3 is the main body of the paper, we derived the results about general ruin probability in a kind of continuous time risk model with deficit - time geometry distribution of claim inter - occurrence time. the martingale approach is a good procedure to get the expression of ruin probability about a class of continuous time risk models with deficit - time geometry distribution of claim inter - occurrence time. we also take advantage of change of measure idea from it

  5. In the study of risk theory, a class of continuous time risk process with deficit - time geometry distribution of claim inter - occurrence time was made into a strong piecewise - deterministic markov process with the theory of piecewise - deterministic markov process and by introducing a supplementary variable. martingale approach is one of the most powerful methods of pdmp. the programming process is getting the ruin probability from the martingale construction. we use the idea of change of measure in the programming process and find the result and the function of adjustment coefficient

  14. By the simulation results, it is verified to have excellent performance. a class of uncertain nonlinear systems which can be transformed into strict feedback nonlinear systems is investigated based on feedback linearization approach of differential geometry. an adaptive robust controller with l2 - gain is proposed by using backstepping technique. the numerical method is given and it is proved to be practical by simulation results. lt is a more practical method to solve hji for a special nonlinear system because the problem to solve hji is very difficult in general case, and only get the approximate solution when it can be solved. an effective method to solve hji is presented for a class of nonlinear system which is ordinary

    考慮到一般情況下,求解hji是非常困難的,並且也只能得到近似解,因此,在系統設計時,針對具體非線性系統的特殊結構以求解hfl是系統設計的一種行之有效的方法,基於以上考慮,對一類具有廣泛工程背景的非線性系統,提出了一種求解hfl的有效方法,便於實際應用。最後,從波能譜的角度,研究隨機海浪的模擬問題,給出了船舶橫搖模擬中需要的隨機海浪有效波傾角的模擬方法。
