By analysis and comparison upon average grade and weighted average grade of blast-holes and average grade calculated by cubic-polynomial fitting,a conclusion has been made that average grade obtained through above mentioned calculation is more practical and conforming with the change rule of geological grade.

A human walking pattern was analyzed and researched in detail and the mechanical prototype was known as humanoid special for the leg,thereby a humanoid stable walking pattern during one walking cycle was planned for the bipedal robot based on cubic polynomial algorithm.

To remedy drawbacks identified in the traditional soft and hard threshold for image denoising,this paper presents a new threshold quantization method,which applies cubic polynomial interpolation to a hard threshold to achieve the continuity and differentiability for the new threshold function.

The continuity and differentia-bility are achieved by using cubic polynomial interpolation based on hard thresholding.
