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 disorder of the thienyl ring and〓 groups in 11, 12 and the disorder of water in the packing of 14 may be responsible for their triboluminescent activities.Ⅲ. A dinuclear triboluminescent complex,〓(15)(where TTA=2- thenoyltrifluoroacetone, PyO=N-oxide pyridine), was synthesised and its crystal structure and triboluminescence spectrum were determined.

According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.

"The extragalactic background is very faint, and it is easily confused with the bright emission from the Milky Way," says Ackermann. With the background isolated in their studies (these background measurements are published in the 12 March edition of the journal Physical Review Letters ), Ajello and Ackermann then began to compare it with observations of relatively nearby active galaxies with black holes (called active galactic nuclei, or AGN).

系外伽玛射线背景是非常微弱的，而且很容易受到系内辐射源的干扰，（ Ackermann 等人对背景值的测量公布于3月12日的《物理评论快报》上）， Ajello 和 Ackermann 同时将这个测量结果与附近已被观测过的相对活跃的星系黑洞参数进行比较，这些参照对象有个专有名词，称为活动星系核， AGN 。

We now know that the corona we see has three main parts: emission from hot coronal gases, absorption from the solar photospheric spectrum reflected from dust particles in interplanetary space relatively near the Sun, and a continuum from scattering of photospheric light off coronal electrons .
