Experimental Procedure An Al-7%Mg alloy was prepared using a resistance furnace.
(a) Al-7%Mg alloy cast billets.
Effect of pressure on cooling rate during squeeze casting of Al-7%Mg alloys.
Thus, the cooling rate seems to be the main factor for grain refinement in squeeze casting of Al-7%Mg alloy.

Figure 6: Electroluminescent spectrum of encapsulated devices: (a) EL spectrum of devices encapsulated by curing at 80oC for 2hrs.
(b) Comparison of EL spectra of devices encapsulated by curing at 80oC for 2hrs with bare devices.
(c) Comparison of EL spectra of devices encapsulated by curing at room temperatures with bare devices.
These reactions lead to C-Al or C-O-Al strong covalent bonds between the metal and polymer [30].
Interaction Adhesion Energy (J/m2) PDMS-Al (CBBD) 39 PDMS-Al(AFM) 8.6 Al-MEH:PPV 3 PEDOT:PSS-MEH:PPV 32 ITO-PEDOT:PSS 40 Glass-ITO 0.3 From Table 1, it can be seen that the adhesion between Al and PDMS is approximately 3 times greater than the corresponding adhesion between Al and MEH-PPV.

El-Ghamry et al. [19] demonstrated a method for indirect measurement of cylinder pressure for diesel engine by using acoustic emission signal, where an analytical algorithm was developed based on RMS analysis in both time and frequency domain over different conditions of engine speed, engine type and load.

In 1979, Novak et al [2] put forward a coherency model in the earthquake engineering based on the coherency model of wind and utilized the model in the pipeline research later.
Wang et el [15] gave the value of parameters corresponding to the above mentioned five models through nonlinear parameters fitting method.

Previous researches show that the WW3 wave model can simulate the South China Sea wave field [8-9], meaning that it is possible to realize the numerical forecasting of wave power density by using WW3 wave model. 5.2 Long-term prediction of wave power density based on some important astronomy and earth factors Dodet et al. [10] has found a strong positive correlation between SWH (significant wave height) and the North Atlantic Oscillation (NAO) index at northern latitudes of the North-East Atlantic.
We have found that El Nino phenomenon has a significant influence on the climate change in the China Sea and surrounding waters [11].
We expect that we can analyze the relationship between China Sea wind field and El Nino, and take advantage of the wind field to drive WW3 wave model to simulate the China sea wave field, to explore the intrinsic link between China Sea waves field and some important astronomy and earth factors, such as El Nino, to predict the long-term variation of wave energy, thus providing guidance for the long-term plan of wave energy development.

Associated algorithms for the numerical treatment have been discussed, e.g., by Miehe et al. [15].
For Eq. 5 the definition of the product H s�H is introducedH s�H = 1 2 (HikHjl ei ⊗ ej ⊗ ek ⊗ el + HilHjk ei ⊗ ej ⊗ ek ⊗ el) . (6) Furthermore, the second order tensor H represents the following abbreviation according to Lemaitre et al. [1] H = (I − D) − 1 2 . (7) The definition of the fourth order tensor M, shown in Eq. 5, has its origin in the decomposition of deviatoric and hydrostatic stresses.
