In the new method for two-dimensional problems the line integrals onboundary elements are converted into the evaluation of potentialfunctions at the ends of these elements.For three-dimensional cases,thesurface integrals on the usual boundary elements are transformed,through an application of Stokes'theorem,into line integrals on thebounding contours of these elements.

边界轮廓法是刚刚出现的一种新型的边界元法，该方法的核心是利用边界积分方程被积函数散度为零的特性，对二维问题，原积分方程中沿边界单元的线积分被化为单元两端点势函数之差计算，对三维问题，将边界单元上的面积分转变为沿单元轮廓的线积分，它是一种十分简便有效的边界元新技术。

生产地质、矿山测量、生产计划、生产管理等是露天矿生产的主要核心环节，如何准确、有效地对这些信息进行综合管理，并充分利用这些信息实现管理的科学决策，是提高矿山企业生产效率、管理水平和经济效益，并推动露天矿山科技进步亟待解决的重要课题之一。

X 6 x 25 mm3 tested plates were cut from samples prepared from heating the PLLA powder at 220 oC under vacuum without pressure and gradually cooled from 220 oC until room temperature in a pot vented with nitrogen for one night. The crystallinity value of resultant samples was 43 %. These tested plates were implanted in the dorsal subcutis of S.D. rat after sterilization with ethylene oxide and removed at 1 d、3 d、7 d、21 d and 35 d intervals. These specimens were examined histologically with paraffin embedding section and resin embedding grounding section by light microscopy to evaluate tissue response. Three points bending test, viscosity and thermal properties were also examined.
