The contraction of lattice constant and structured green-yellow-red emissions were analyzed.
The XRD shows that the doping does not change the wurtzite structure of ZnO for the doping concentrations ~5% and we could not find any Fe cluster in the XRD measurement, so we assume that Fe occupied the Zn site without changing the wurtzite structure.
The double peak structure of the deep level emission is different from the pure ZnO emission.

From primary to secondary school, our curriculum has been formed in accordance with scientific systems such as mathematics, physics, chemistry, geography, and biology.
Some institutions have adopted ideas such as big chemistry, big biology, big medicine.
The result is that a large number of students will choose science major such as chemistry, biology and pharmacy.
Expansion of enrollment has diversified the students’ education levels, knowledge structures and value orientations.
Then the talents trained could have interdisciplinary knowledge structures and comprehensive abilities.

Activitor must has especial molecule structure.
One function of the molecule structure is to absorb nanometer particles, the other character is suitable length of stretch key that is dispersed into fluid easily.
There are mainly two kinds of polishing processing: the one is chemistry processing, the oxidant material and acticator, which are immingled in suspension fluid, are redoxed with silicon atoms in the surface of silcon wafer; another is machining processing, the reactant material in the above chemistry processing is swashed to disengage from silcon wafer surface.
New silicon atoms that come out is oxidatived, reactant is swashed again, and in this way, the chemistry processing continues.

Our research can provide some references for further modifying the structure of bagasse xylan and further develope the oretical research about antiviral.
This phenomenon evidenced that the crystalline structure of native bagasse xylan was destroyed after esterification[14].
This diffraction peak may have originated from a new ordered structure of product[15].

Abstract: 3-Amino-4-aminoximidofurazan (AMF) and 3-Amino-4-cyanofurazan (ACF) are important precursor of synthesizing new furazanon (furoxano) energetic compounds.
Their parameter was compared to deepen the study of structure-activity relationship.
Fig. 1 Molecular structure of AMF and ACF Experimental The theoretical chemical investigation.
According to crystal structure of AMF [9], a crystal unit was selected as the initial structure of AMF, remove coordinate data of hydrogen of methyl in the AMF, increased coordinate data of N4 as the initial structure of ACF.

The ZnO particles with mesoporous and lamellar structure were synthesized in the method of precipitation, using zinc acetate as precursor.
The results showed the obtained ZnO particles were irregular polygons with lamellar structure, and the particle size was in the range of 50 nm to 300 nm.
The crystal structure was determined by the X-ray powder diffractometer (XRD) of D/MAX-rB, which was radiated by Cu Kα.
Moreover, the surface area and pore structure parameters of samples were calculated by BET equation and BJH method.
