成三角形

To avoid the reading error of huge STL files and improve the precision, a method to divide a huge STL file into several small STL files which are to be built continuously is put forward.

为了避免巨型 STL格式文件的读入错误和手工粘接带来的误差，研究了沿垂直于Z方向将巨型 STL格式文件分割成多个 STL格式文件，连续依次成形的方法，研究了分割面轮廓的拓朴处理和分割面切割的轮廓环分解为三角形的算

To avoid the reading error of huge STL files and improve the precision, a method to divide a huge STL file into several small STL files which are to be built continuously is put forward. An algorithm for tanslating the loops in the dividing face into the triangles is presented.

And their improved methods were also researched, for example the force density method with the triangle element transformed the three links, surface stress density method, surface stress density method of sub-structure and nonlinear finite element method of little youngs modulus.

并且对它们的改进方法，比如三角形单元转化成三杆单元的力密度法、面力密度法、考虑子结构的面力密度法和小杨氏模量的非线性有限元法进行了深入的探讨。

A roof with two slope s that form a triangle at each end is called a gable roof.

有两个斜面的屋顶在两端各成一个三角形，称为山形墙屋顶。

Sensitive range from 49.1% to 100%, specificity range from 18.2% to 90%,accurate range from 45.5% to 88.3%, PPV range from 34.1% to 95.2,NPV range from 22.2% to 100%,the combine sensitive was 82.7%,specificity was 63.3%;there were not obvious publish bias in the 9 articles, and there was heterology of the 9 articles, the forest figure show RR was 2.34[1.43,3.05],and its 95% confidence interval did not include 1,the chance of malignancy nodules'SUV above 2.5 were more than benign nodules.

文献报道的敏感性49.1-100%，特异性18.2-90.0%，准确性45.5-88.3%，阳性预测值34.1-95.2%，阴性预测值22.2-100%，Meta分析合并后的敏感性82.7%，特异性为63.3%，准确性为71.8%，阳性预测值80.8%，阴性预测值57.0%；漏斗图成近似倒三角形，认为文献无明显发表偏移；对文献异质性检验，P小于0.05，认为文献来源存在异质性；选用随机效应模式得到森林图，RR为2.34[1.43，3.05]，其95%的可信区间不包括1，认为肿瘤病人最大SUV 2.5法呈阳性的可能性大于非肿瘤病人，二者之间具有统计学差异；两篇来源于日本的文献显示日本国的18F-FDG PET肺占位显像假阴性率高于我国。

You can use square, round, hexagonal, triangle or scale tiles.

你可以使用正方形，圆形，六边形，三角形或者成比例的瓷砖。

In the second case, popularized by Hoppe [12], the two endpoints of an edge are contracted to a single point and the triangles that degenerate in the process are removed.

第二个是由Hoppe提出的边的两个端点合并成一个顶点，而退化三角形移除掉。

For both projects I analysed their essence and translated their concepts into an Icosahedron; a modular Origami shape made from 20 equilateral triangles meeting at each 12 corners.

在这两个企划中，我分析了书和海报的本质，并将其概念转化为一个20面体，以日式的摺纸手法摺成，完成之后会有20个等边三角形落在20面体的12个角上。

The effects of HAuCl4 concentration were also studied. The particles with obtuse triangle, hexagon and round shapes were synthesized and in situ stabilized by the biopolymer.

在紫外照射条件下HEC能够将金离子还原成具有独特钝角三角形、六边形和圆形等不同形状的粒子，并将其稳定在水溶液中。

The area of every triangle equals the area of the parallelogram .

每个三角形的面积等于拼成的平行四边形面积的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
