This paper introduces several common methods for surveying and designing the vertical and borizontal section as well as ways of data recording,which is carried out by means of conversion of data transmission and data format with the aid of VB6& AutoLISP language and by the operation of Auto CAD R14,resulting in automatic creation of transect map and the formation of electronic file.

By means of conversion to standard axle load and calculation of accumulated applications of the equivalent axle load, it could be concluded that overloading is one of the most important reasons for the premature failure of cement concrete pavement structures.

By means of conversion switch on counter,the counting assembly may indicate axial travel that the boring bar moves automatically or manually and may indicate total axial travel.

The microstructure of the compound layer formed by plasma nitrocarburizing of steels has been investigated by means of conversion electron, conversion X-ray M?ssbauer spectroscopy (CEMS, CXMS) and X-ray diffraction.

A sea weed (Scirpus grossus Linn ) was taken as an experimental plant to indicate radioactive pollution in estuaries. The results showed that the accumulation of 137Cs,65Zn, 60Co, 50Fe and 54Mn hy Scirpus grossus was proportional to their concentration in the soil. After the nuclidcs in the soil were washed out for one month, more than 9. 2% of the nuclides in Sctrpus grossus still remained , within the detection limit . Absorption of the nuclides from water by the stem above soil was larger than that from soil...

After the nuclidcs in the soil were washed out for one month, more than 9. 2% of the nuclides in Sctrpus grossus still remained , within the detection limit . Absorption of the nuclides from water by the stem above soil was larger than that from soil by the root. The concentration factors of the root . the stem underneath soil and stem above soil for the nuclides were determined. Radioactive pollution degrees of both the sea water and the soil can be deduced by means of conversion of the concentration factor's formula.

The paper describes the indoor shear creep experiment for the week intercalated bed in the dan-gerous rock body of Lianzi Cliff, gives the displacement-time curves of creep. The permanent strength of the week intercalated bed is obtained by means of conversions. Then, according to the properties of the creep curve, we make use of Burgers Model and Kelvin-Voigt Model to describe the two kinds of curves of creep,which correspond to shear stresses larger and smaller than permanent strength, respectively.

Computing the area of a planar graphs is valuable in engineering. A highly efficient algorithm for computing the area of an arch field of a power polynomial is presented at first. By means of conversions of Bezier curves, B-spline curves and uniform B-spline curves to power polynomial curves, and by means of the subdivision of power polynomial curves, an efficient computing method is presented for finding the exact area bounded by non-knotted planar composite piecewise polynomial curves, which may...

Computing the area of a planar graphs is valuable in engineering. A highly efficient algorithm for computing the area of an arch field of a power polynomial is presented at first. By means of conversions of Bezier curves, B-spline curves and uniform B-spline curves to power polynomial curves, and by means of the subdivision of power polynomial curves, an efficient computing method is presented for finding the exact area bounded by non-knotted planar composite piecewise polynomial curves, which may be any form of the four commonly used polynomials, mentioned above, in CAD/CAM. The shape of boundary is not restricted at all, and the origin of coordinate systems can be in any position. At last the results are generalized to the case for knotted composite curve boundary, therefore a complete resolution for computing the area bounded by composite polynomial curves is given.
