Wesuggest that the shifting endotherm originates from the transition of oxygen-intercalated C60 to a merohedral disordered phase,in which the rotation of fullerenemolecules is partially impeded by oxygen.

我们建议那个移动的吸热峰来自于周围有氧的那部份C60，从简立方相转变到不全无序相。不全无序相的形成是由于氧对C60转动的部份阻碍所造成。

Based on expansion of ODF in series of Generalized Spherical Harmonics by Bunge, we design programming in Orientation Distribution Function for polycrystal which contained five thousands crystals based on increment arithmetic of Voronoi. Geometrical data information, ODF of every crystal in polycrysal are imported to Open Graphics Library to draw, that means we implement visualization of ODF for every crystal in polycrystal.

主要针对具有立方结构的多晶体材料，采用Bunge级数展开法模型计算取向分布函数的理论模型，利用C语言在VC++环境下对ODF值进行了计算，并以Voronoi增量算法为基础生成包含有5000个晶粒的多晶体材料各晶粒的几何数据信息，与计算得到的ODF值一起导入OpenGL进行可视化处理，直观显示了多晶体材料中ODF值在各晶粒内的分布。

The crystal of DPCP-ETSC belongs to the orthorhombic system, space group Pna21, and its lattice parameters are as follows: a=1.1478 (2) nm, b=1.3545 (2) nm, c=1.1994 (2) nm, V=l.8646 (4) nm^3, Z=4, Dc=1.345 g/cm^3,μ=0.194 mm^(-1), F (000)=792, R=0.0345, wR=0.0694. The intermolecular hydrogen bonds led to the formation of chain-like one-dimensional compound along c axis and extended along ab plane to form the wave-like supramolecular structure.

DPCP-ETSC晶体属于正交晶系，Pna21空间群，晶胞参数：a=1.1478(2)nm，b=1.3545(2)nm，c=1.1994(2)nm，V=1.5646(4)nm^3，Z=4，D=1.3459/立方公分，μ=0.194mm^(-1)，F(000)=792，R=0.0345，wR=0.0694，此化合物通过分子间氢键形成沿c轴成链状，沿ab平面成波浪状的超分子结构。
