We consider the class of parametric curves that can be represented by combination of control points and basis func- tions. A control point is let vary while the rest is held fixed. It’s shown that the locus of the moving control point that yields points of zero torsion is the osculating plane of the corresponding discriminant curve at its point of the same parameter value. The special case is studied when the basis functions sum to one.

Vacuum loading has been examined as a way of preparing uniformly consolidated soft clay samples. The facility and loading procedure are described in this paper. An analytical solution to the three dimensional consolidation equation is derived for estimating the degree of consolidation of the soil sample with vacuum loading. The given example shows that the predicted degree of consolidation of a soft clay bulk with vacuum loading is close to that measured in the consolidation process.

With the chemical synthesis of zinc oxythiomolybdate (ZnMoO2S2), its characters were studied by thermal analysis and X-ray diffraction method. The tribological properties of ZnMoO2S2 were studied by high-temperature pin on disc tester, the results show that ZnMoO2S2 has good lubricating property from room temperature to 700 degrees C, especially from 100 degrees C to 300 degrees C, the friction coefficient is about 0.1.
