1. This paper tries to generalize the throwing objects from the one dimension pin to the convex curve in two dimension, and even the three dimensional regular tetrahedron and regular hexahedron. 在蒲丰投针问题的基础上,把投掷物由一维的针推广到二维的凸曲线,三维的正四面体、正六面体;
2. We can now use tetrahedron and hexahedron elements in three-dimensional stress analysis. 我们现在在三维应力分析中采用四面体单元和六面体单元。
3. Harappan engineers followed the decimal division of measurement for all practical purposes, including the measurement of mass as revealed by their hexahedron weights. 哈拉帕的工程师沿用着十进制的刻度划分。实际上,包括质量的测量,都是通过他们的六面体法码而表现。
4. Pillows are used in China usually are made in rectangle pillar or hexahedron, so the both sides are square which embroidered all kinds patterns, that is "embroidery on pillow sides". 在中国的民间,通常用的枕头是以布缝制成长柱形、六面体,两端多呈正方形,上面刺绣各种图案,即我们所说的“枕顶绣”。
5. In this paper, strain and stiffness matrix of isoparametric element with eight nodes and hexahedron are derived in detail. 推导了八节点六面体等参单元的应变矩阵、刚度矩阵,对该单元的位移解收敛性和畸变敏感性进行了分析。
