A simple 1-D solidification theory with the following equation (1) has been used for predicting thicknesses of cast magnesium strips.
Sheet thickness obtained was 1.6mm to 2.2mm for AM60, 1.75mm to 2.3mm for AZ91, and 1.6mm to 2.4mm for AZ121

Fig. 3 The Sketch of scheme 1 Fig. 4 The Sketch of scheme 2 Another trial scheme is the roof doesn't break up, directly connected the tower as a whole.
Scheme 1: the roof connected with all the towers; Scheme 2: the roof hinged central tower, only connected to the other towers through sliding bearing.

The FT-IR spectra of all samples show major adsorption bands at 3720, 3442, 1620, 1094, 792, 620, and 479 cm-1, as shown in Fig. 2.
On the surface, the band at 1620 cm-1 represents the H-O-H bending vibration of water, that at 1094 cm-1 may be attributed to siloxane (-Si-O-Si-) group stretching, the peak at 792 cm-1 may correspond to SiO-H vibration, and the band at 479 cm-1 may be attributed to the O-Si-O stretching vibration of SiO4 tetrahedron [6].
These groups appear as a broad band with the middle wavelength at 3400 cm-1 to 3500 cm-1 [7].
The same results were detected by XRF in Table 1.

Host phonon energy can be obtained by the phonon sideband (PSB) of Eu3+ ions [12] and Raman spectra [13,14].Fig. 1 displayed Stokes scattered Raman spectra for Yb3+-Ho3+-codoped GP80 and GP08 glass samples.
It can be seen from Fig.4 the energy difference of the 2F5/2 and 5I5 level was about 800cm-1, while the energy difference of the 2F5/2 and 5I6 level is about 1800cm-1.
It suggested that to populate 5I5 level from phonon-assisted energy transfer process from Yb3+ ions only one phonon is needed, while more than two phonons are needed to populate 5I6 level in germanium glass samples whose phonon energy is about 800cm-1 (shown in Figs.1 and 2).
