three by three arrangement

Main equipments used were chosen. Design of three-dimensional arrangement was realized by a PDMS softer.

对工艺系统的主要设备进行了选型，并运用PDMS软件进行了三维布置设计。

The paper takes Dongjiang Fourth Bridge in Huizhou city as an example for searching for the influence of Pre-stressed strand arrangement on the craze of box girder. By using great Finite-Element analysis ANSYS special part model of box girder have been built up through adopting three-dimensional body element.

为了探求预应力的布置对箱梁开裂的影响，以惠州市东江四桥为例，利用大型有限元程序ANSYS，采用三维体单元建立箱梁节段空间局部模型。

The properties of the molecular and supramolecular crystals are determined, on the one hand, by the chemical structure of the molecules and, on the other, by the three-dimensional arrangement in the crystal lattice.

分子晶体及超分子晶体的宏观性质一方面由分子的结构决定，另一方面也和分子的排列方式有关。
