We found that during the growth process the double steps first grow separately and the connected by short bridge before tangential growth. After eighth or ninth layer the spiral steps would merge into intact elliptic layers. At the merging point right-handed spiral sources might appear but the left ones always overgrow it which made the whole growth topography looked like left-handed apparently. It indicated that the EAFP molecules has strong ability to adjust itself to adapt the environment. 5. Through various analysis of interactions in the EAFP crystals it indicated that there were 218 residue interactions between 12 symmetry-related EAFP molecules around one EAFP molecule, 18 strong ones and 72 weak ones .

EAFP在低过饱和度下的螺旋生长过程中会出现台阶的合并，从而表现出单-双的螺旋台阶，在小范围扫描中捕获到了这种现象，使得对螺旋生长台阶的合并过程有了更加深入的认识；并且台阶的生长受到沿晶体学b轴方向上的21螺旋对称的控制；当台阶生长至第八到第九层时，螺旋台阶会自动地形成完整的生长层，这充分说明了EAFP分子或分子簇具有良好的自身调节能力，这样在晶体生长过程中，晶体的缺陷减少，晶体质量提高，这也可说明EAFP晶体的x射线衍射能力很强的原因。

The establishment and relaxation processes of the transient gratings, which are formed by two recording 514nm beams with different polarization directions, SS, PP, SP and ±45℃, are investigated. Using the weak absorption of the chromophores at 632. 8nm and the positive dichroism of the chromophores molecules, a kind of bi-photonic transient gratings, owing to the periodic distribution of Trans and Cis isomers, is established first time in azo-dye doped polymeric bulk sample.
