立方体的

In addition, some experience formulas for them are regressed. The third chapter establishes a unified S-N curve equation to calculate multi-axial fatigue ultimate strength of concrete considering both the effect of confinement and minimum/maximum stress ratio, based on the triaxial fatigue test data in this paper and the test results under uniaxial and biaxial fatigue loading in previous literatures. Moreover, the consistency of calculating condition fatigue ultimate strength with fatigue life distribution and initial ultimate strength distribution is analyzed.

第二章简要地介绍了本文三轴疲劳试验装置，进行了两向等侧压约束下混凝土立方体试件三轴受压等幅和变幅疲劳试验，分析了三轴受压疲劳破坏机理，给出了相应的疲劳破坏试验判断标准；得到了混凝土在两向侧压约束下单级和多级受压疲劳的变形发展规律，包括最大纵向应变、残余应变、最大纵向应变率和疲劳变形模量等随循环次数的发展规律以及疲劳损伤的演变规律，并给出了相应的经验公式。

Rubik first envisioned his venerable cube, he imagined intricately machined and assembled pieces of plastic pivoting on six axles, smoothly shifting positions into any of a possible 43 quintillion arrangements of pieces.

当鲁比克艾尔内第一所设想的古老立方体，他想象的错综复杂的加工和组装的六轴旋转的塑料件，顺利地转移到一个可能的43件千万亿安排任何职位。

This algorithm generates spatially regular triangle meshes and can be very storage-consuming and hard rendering when the volume data is huge.

利用走访立方体法可以撷取单一解析度的三角形网格，但针对非常大型的三维影像可能会产生过多的三角形，造成储存及显像上的困难。

The overall design focuses on a 'box within a box' concept (inspired by conceptual artist Dan Graham's work with transparency and reflection) incorporating the isolation of different living space areas: the mezzanine, the new back extension and cubes that resourcefully double up as furniture and smaller corridors, all inform one another without physical contact - maintaining an optimum fluidity of space.

整个设计围绕着"盒中盒"的设计理念（受概念艺术家Dan Graham作品中的"映像和透明"所启发），并将不同的生活区分离开，将夹层，后屋延伸，和立方体巧妙地进行结合，配以更简洁和家具和缩小的走廊——所有这些使得居室布局显得丰富动感而不局促。

In the algorithm, tangent plane of the surface at each point is first calculated according to the point and its neighbor points. In an optimized sequence, normal vectors of the tangent planes are oriented to the outside of the surface. Finally, marching cube method is used to output the triangular representation of the surface.

该算法首先根据测点的邻近测点估算曲面在该测点处的法矢，并采用优化的顺序对法矢方向进行调整以使各测点处的法矢都指向曲面外侧，最后用步进立方体算法输出三角网格模型。

The edificial structure consists of two formally contrasting elements: A geometrically stringent, cube-like shell volume and a freeform positioned centrally in the interior.

建筑物的结构由两种对比强烈的元素构成：严谨的几何立方体外壳造型以及内部中央自由的布局。

Plato's Timaeus posits the existence of a fifth element (corresponding to the fifth, remaining, Platonic solid) called quintessence, of which space itself is made.

柏拉图的《提马亚斯》安置了第五种元素的存在物（与第五相应，保持着，理想的立方体），称为精萃，空间本身就是这样制成的。

As the number of dimensions increases, the cube becomes sparser—that is, many cells representing specific attribute combinations are empty, containing no aggregated data.

随着维度数目的增加，立方体变得更稀疏，即表示某些属性组合的多个单元是空的，没有集合的数据。

For example, a cube is made up of six quadrilaterals where each vertex is shared by three polygons, but a different normal should be used for each of the three instances of each vertex, but a sphere is made up of many polygons where all vertices have common normals.

例如，一个立方体是由六个四边形组成，而每一个顶点被三个多边形共用，但是每一个顶点的三个实例应该使用不同的法向量，而由许多多边形组成的球，其所有顶点就有同样的法向量。

Given the length of the same color to the color of the small wooden sticks and try to design an alg...

给定12 根长度相同的彩色的小木棒的颜色，试设计一个算法，计算用这12 根长度彩色小木棒可搭出多少个不同的小立方体。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
