MgO is a B1 structure, a = 0.4212 nm [12], kS=6.19×10-12 Pa-1 is determined by k=1/B with B =161.6 GPa being the bulk modulus [13], VS = 5.60 cm3g-atom, ρS=3.6×103 kgm-3 [14], VL = 6.36 cm3g-atom and gL = 0.585 Jm-2, as a first-order approximation for MgO and FeO have the same structure, we assume they have the same volume expansion and liquid surface tension. kL=93×10-12 Pa-1 as a first-order approximation under higher pressure [10]. f is calculated by Eq. (2) and f = 6.45 Jm-2.

Phytoplankton are at the bottom of marine food chain, their structures changing will inevitably affect the whole ecosystem [5]Chen YL [6]1992) pointed out that the seasonal effect of the cooling water is significant, the thermal effects is larger especially in summer, some algae will temporarily disappear at this time, and then the composition of basic phytoplankton species will change.

Introduction X-ray diffraction (XRD) analysis, is an important experimental method and the way to analyze the structure of a material, while it can not damage the specimen [1,2].
It is the first method to investigate the microstructure of a material, has been applied in physics, chemistry, earth science, materials science and so on.

The choice of ABS and PP alloy, modifying the disadvantages, improve material, can obtain the comprehensive advantages of the two, and accelerate the development of. [6-8] different common mixed method, the results are not the same, such as the use of solution method for thin film like mixture, solvent, precipitant, precipitation process change will influence the phase composition changes. [11] in addition, double roll kneading machine, mixer, extruder, solution or emulsion blend will make the blend morphology change of structure. 
The change of temperature, shear stress also influences the structure and morphology of blends. [12] all kinds of chemical materials of ABS and PP alloy research improvements are continuous development.

The reactions of photo oxidation and thermal oxidization include cross-linking and fracture, after that the amounts of carbonyl, carboxyl, unsaturates and cross-linked structure are increased.
According to the national standards GB/T 7141-2008, cutting samples as required structure and size, setting temperature is 50 ℃, and 24 hours are one cycle, so the aging times are 24h, 48h, 72h, 96h and 120h respectively.

Synthesis and Properties of a New Diarylethene Bearing Isoxazole Moieties Hui Li, Yuanming Tu, Gang Liu* College of Chemistry and Chemical Engineering, Jiangxi Science and Technology Normal University Nanchang 330013, P.
During the reversible photo-isomerization process, photochromic diarylethenes can cause changes of not only their molecular structures but also their physicochemical properties, such as absorption spectra [3,4,8-10], fluorescence [11,12], and so on.
The structures of diarylethene 1o were confirmed by NMR. 1H NMR (400 MHz, CDCl3, TMS): δ 1.24 (t, 3H, -CH3), 2.03 (s, 3H, -CH3), 2.16 (s, 3H, -CH3), 2.57-2.62 (m, 1H, -CH2), 2.74-2.79 (m, 1H, -CH2), 7.33-7.39 (m, 2H, phenyl-H), 7.49 (d, 1H, J = 8.0 Hz, phenyl-H), 7.77 (d, 1H, J = 8.0 Hz, phenyl-H).

Particle morphology, size distribution and structure were determined by TEM analysis, carried out using a field emission transmission electron microscope (Phillips CM 20) at a voltage of 200 kV, equipped with a CCD GIF 200.
However, after background correction, the raman signal revealed a clear ferrite structure (Fig. 3).
