Dynamic loading was tried using the dynamic loading facility and model waves modified artificially from the famous earthquakes, so called El Centro and Taft, as shown in fig. 11 and 12.
As shown in fig. 12, “El Centro 2” is an instance of an artificial input wave modified from a real El Centro wave.
A turn of artificial earthquakes is determined as a set of Taft level 1, Taft level 2, El Centro level 1 and El Centro level 2.

The statistical analysis show that the frequency of dust storms in the most of Northern China are increased during the La Niña, while decreased during the El Niño.
The second SVD mode of Pacific SST is very similar with El Niño.
According the second SVD mode, It is clear that the frequency of dust storms in the majority of Northern China are decreased during the El Niño. 3 Results of dust model system experiments The integrated numerical simulation and forecast system of dust weather is usted to verify the influnence of Pacific SST on the dust storm in China.
(2) According the SVD analysis, the frequency of dust storms in the most of Northern China is increased during the La Niña, on the contrary, the frequency of dust storms in the majority of Northern China is decreased during the El Niño

Experiment The device structure was ITO/MeO-TAD(15 nm)/ NPBX (40 nm)/DPVBi (x nm)/Rubrene(0.3 nm) /DPVBi (20-x) nm /BCP (5 nm) /Alq3 (30 nm)/LiF(0.5 nm)/Al.
The normalized EL spectra of four devices at 8 v is shown in Fig.2.
The broad EL spectra at 8 v cover the whole visible range from 380 nm to 780 nm.

The fig.1 shows the structure of ZnS QDs EL device represented by phase segregation, the ZnS QDs distributed in a layer above the TPD: PMMA film.
The EL spectrum of the EL devices were measured at room temperature using fibre optic spectrometer CCS Series by THORLABS Company (Germany) which covering range from (200 - 1000) nm and the resolution of 1nm.

Hence, in this letter, we will present an improved method for preparing such a single-layer EL polymer thin film.
However, the single layer blue light PLEDs fabricated in this section have the structure of ITO/PVK(100mg)+TPB(5mg)/LiF(10Å)/Ca(100Å)/Al(1000Å).
Configurations of the EL device and the molecules used.
The single-layer white light PLEDs fabricated in this section have the structure of ITO/PVK(100mg)+ TPB(5mg)+ rubrene(Xmg)/ LiF(10Å)/ Ca(100Å)/ Al(1000Å).
Conclusions In conclusion, an improved method for preparing single-layer EL thin films was presented.

Regarding intermetallic particles, Fe-containing phases, as the brittle β-AlSiFe, usually present in casting alloys, are cathodic with respect to the Al matrix and, thus, contribute to corrosion phenomena at the interfaces with the Al matrix [5, 6].
In fact, Mn is reported to reduce the cathodic effect of Fe leading to a less intense reactions with the Al matrix [8, 9].
However, the effect of Cr and Mn on corrosion resistance of casting Al-Si-Mg alloys is hardly reported in literature.
