The method of removing statistics fluctuation with factorial moment was introduce and the cumulant variable able to even for distribution of multiparticle production was proved.

Discussion on the mode and conditions of quantitative change accumulation in conflict transform;

Wheel-rutting index(WRI),a new index for evaluating the whole-term high-temperature stability of asphalt mixture is presented by taking into account all the factors affecting the high-temperature performance,such as the velocity,the cumulate deformation and the maximal permanent deformation,and the analysis and comparison of the degrees of track ruts in different periods are then carried out.

Research on accumulative deformation behavior of soft clay under cyclic loads;

Compared with other kinds of sensors,module matching FBG has a better test effect,and this kind of FBG is able to reflect the accumulative deformation of asphalt mixture to some extent.

By use of horizontal velocity data observed by GPS during 2001—2004 and 2004—2007 in the northeastern margin of Qinghai-Tibet block,aided by the negative dislocation model,the characteristics of horizontal crustal movement and the status of strain accumulation of this area are researched and following conclusion are drawn.

By use of the regional leveling and GPS observations in Sichuan-Yunnan area during 1994-2006,aided by the negative dislocation model for the elastic block boundaries,combining with the total characteristics of deformation cross-fault,the recent status and intensity of strain accumulation of tectonic blocks and their boundary faults in Sichuan-Yunnan area are studied.
