中三角形 meaning in English

medial triangle

Thermal stress analyses and comparison of triangular and trapezoidal threaded - adhesive joints applied in non - magnetic dewar
无磁杜瓦中三角形和梯形螺纹粘接接头的热应力比较
Geometry continuity of the triangular facets is analyzed in the course of generating stl files . the index relation is built up between every triangular facet by making use of this continuity
通过分析stl转化过程中三角形面片之间的几何连续性，应用其连续性，使得各个三角形之间建立一种索引关系。
In which , the algorithms of model slicing based on stl are more important . the thesis studies many emitted algorithms in this field , finds out although they executing approaches are different from each other , they follow a same principle , that solve the crossing line by the method of finding triangles according to slicing plains
论文研究了当前多种基于stl模型的分层方法,发现这些算法虽然在具体的执行过程上表现各异,却在实现上遵循了相同的思路:都采用了为分层平面搜索三角形的“逐层”方式,由于实际stl模型中三角形数量巨大,所以这种搜索无疑是非常耗时的。
