At present,the process,equipment and system control of the new dry process cement production come to maturity,output of the kiln system is greatly increased and the ralevant parameters as inclination,rotary speed,power,material load rate and residence time are optimized step by step.

In the light of the problem of the calculation of the wingwall s b ac k slope ratio and the flap width when the slope is the general angle that often occurs in the construction of the highway s stone-arch culvert, and the problem of the lofting of the arch mouth stones of the round stone-arch culvert, this paper puts forward some practicable solving methods.

Using improved thick shell element program, this paper analyses the space mechanics of shoping plate arch bridge with varies slope, produces the difinition of limitation slope.

It analyzes in detail the influence of slope,crankling rigidity ratio,loading type and etc.

In order to formulate an adaptive detector of R peak with high accuracy,the proposed method e mploys HOS-based parameters,such as skewness and kurtosis.

On this base,the skewness of high-order statistic analysis is used to test and verify the effectiveness of the conclusion.

The development of labeling function on taper and pitch in mechanical CAD system;

Development of AutoCAD on labeling taper and pitch according with chinese national standard used ARX;

The span as the parameter analysis is chosen and the seismic response of the different skew angle simple-supported skew girder bridges with the constant and seldom earthquake effect is analyzed.
