Sphere Assembly Model and Relaxation Algorithm for Packing of Non-spherical Particles

非球体填充的组合球模型及松弛算法

When the hollow sphere packing and preparation process are same, the compression properties of HSC are controlled by choosing different diameter pore-forming agent.

空心球结构与制备工艺相同时，空心球多孔材料的密度和压缩性能可以通过选用不同直径的造孔剂来控制。

After reviewing the past researches of the Sphere and Circle Packing problem, this paper points out that such problems are NP-hard and that until now there are no deterministic algorithms for solving them.

在回顾了球（圆）形Packing问题的研究现状后，指出此类问题是NP-hard问题，迄今不存在确定型的求解算法。

The experimental results seem to show that the short-range order of amorphous Cu 56 Zr 44 alloy at room temperature is of hard sphere random dense packing.

实验结果表明，非晶态Cu56Zr44合金在室温下的短程结构类似于硬球无规密堆积分布.在703K过冷液相区内等温退火时发现，当退火时间为3min时，晶化产物主要为Cu8Zr3相；

The research on the relationship between sphere size and packing configuration with packing density and pore size distribution provides a basis for designing and control morphological parameters of materials.

系统深入地探索和研究球体堆积问题中球体大小及堆积形态等与堆积体的堆积密度、孔隙大小分布之间的关系，可以为设计与调控堆积材料的形态结构参数提供依据。

The two-dimensional structural units ( such as silicon-oxygen tetrahedral sheet, octahedral sheet), interlayer space ( or interlayer matter) are assembled according to the sphere close packing manner, and the close packing layers parallel to { 0001}.

结果表明，不同二维结构单元体（包括硅氧四面体片、八面体片、层间域（物））的构筑基本符合球体紧密堆积原理，紧密堆积层平行{0001}；

The parameter can be used to describe the information of spheres contacting an aim sphere. The information is useful to research non-equal sphere packing.

该参数可以用来描述与目标球体接触球体的信息，这在非等径球体堆积时很有必要。
