This paper briefly introduced the progress in time-lapse seismic as shown from the 76th SEG annual meeting. Topics include the repeatability of time-lapse seismic, in which we discussed the effects of shooting and receiving environments on repeatability, the effects of the cable length and its positioning accuracy and stability on repeatability, and the data processing techniques to improve repeatability, new insights into time-lapse seismic, in which we described tube wave time-lapse response, spectral decomposition, and time-lapse VSP monitoring, and problems related to application of time-lapse seismic technology. The comprehensive applications of time-lapse seismic and other geophysical data were demonstrated with the real data from an oilfield. Finally, we summarized the difficulties in using time-lapse seismic and outlooked its future trend.

许多届世园会因其独特的建筑而被人们记住。这些建筑或拔地而起，或开放铺陈，其恢宏壮观无不令世人叹为观止。它们既是世园会主题的象征，同时又成为世园会物化了的永久纪念。法国的埃菲尔铁塔就是典型的一例。1889年，巴黎为世园会建立了主题塔——埃菲尔铁塔。日后，埃菲尔铁塔便成为了法国的永久象征。而我们的中国"99昆明世界园艺博览会"同样为我们留下了物化的永久纪念——昆明世博园。

So in this paper based on the characteristics and the optimum state theory of the vehicle, some kinds of control schemes are compared and discussed, and the fuzzy PID control scheme is adopted at last. The relation between air-cushion pressure and fan rotational speed on the optimum driving state is studied. The cushion pressure is used as controlled variable and the fan revolution is used as regulated variable. And transducer and fan motor are actuators.Based on the structure and operating properties of half-tracked air-cushion vehicle, the control system scheme and structure are presented. A control scheme using the self-tuning PID fuzzy logical controller is adopted. Fuzzy rules are set up and some researches have been done for fuzzy tuning method. At the same time the real-time measurement scheme by computer control is proposed, and electric circuits are designed. In the control system of half-tracked air-cushion vehicle cushion pressure P〓 is used as controlled variable and the fan speed n〓 as regulated variable.
