立方体的

Aqua Gen is doing a feasibility study for a plant that can process 45,000 cubic meters.

AquaGen 为了工厂做了可行性的研究，工厂可以处理到45，000米立方体。

Key words: coupled structure-acoustic systems; acoustic pressure; optimization; finite element method

以一矩形板结构一立方体声场耦合系统为实例，得到了优化的结构厚度分布。

At last, based on a mathematical tool: algebraic system, this paper gives definition of spatial data cube.

最后，基于数学工具——代数系统，给出了空间数据立方体严格的数学定义。

Battista and Clements(1996, 1998) indicate that students are difficult to perspect and imagine the hiding cubes, or coordinate orthogonal views of cubes correctly.

Battista与Clements(1996， 1998)指出学童在解决立方体计数的问题时，无法对隐藏的立方体进行透视与想像，或无法正确协调柱体直角的视点，即使到了国小高年级，仍有一定比例的学生计数错误。

"What are you doing" asked the steward,"Just whispering words or encouragement and treating my horse to a sugar cube, try one", came the reply as the owner ate a cube.

是你的做」问乘务员，「刚刚低语文字或鼓励，治疗我的马到一个糖立方体，试一个」，来作为拥有人的回答吃一个立方体。

Two approaches,one called CG method in this paper which based spatial cubic partitioning where the axis-aligned bounding box of the data points is partitioned by a cubical grid,and another based on tree structure such as kd tree are known for the problem.

目前主要有2种方法，一种是基于立方体分割形成的三维立方体体素索引数组的体素栅格（CG方法，另一种方法是基于树索引结构的方法如kd-Tree等。

However, hidden factors limited in 4-7 hidden numbers would unstablly influence students' cubes counting, it shows that the effective grouping is more important than the hidden factors for the students of sixth grade solving the cube enumeration problem.

而隐藏个数因子在有限的4-7的隐藏个数范围内，对於学生立方体计数的影响并不稳定，显示有效的群组方式对六年级学生解决立方体计数问题的影响更甚於隐藏个数的多寡。

The point cloud was divided twice and distributed to 3D cell grids, then ultimate space, internal space, external space were decided for each grid. With the help of each point s sphere space, K-nearest neighbors of the point can be found quickly.

首先，采用二次划分的方法将点云划分到相应的立方体小栅格中；然后，为采样点所在的立方体小栅格确定最终子空间、内子空间和外子空间，结合采样点的球空间，就能很快确定该采样点的K邻域的搜索范围。

What I did was extrapo lated a Group 2 square out into a cube and the opened the cube up.

精神的。我所做的是extrapo lated一组2平方米到一个立方体和开放的立方体了。

On Earth's surface, iron comes in three flavors, standard crystalline forms known to scientists as body-centered cubic, face-centered cubic and hexagonal close-packed.

在地球的表面，铁以三种形式存在，就像身体一样科学家熟知的标准水晶线形态-空间立方体，平面立方体和紧贴一起的六边形。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
