Slabs reinforced with either GFRP bar or steel bars are compared, seen in Table 1.
Ultimate bearing capacities of restrained slabs from test are more than 1 time of those estimated according to codes.

Table 1.
The flexural strengths of Y-TZP after different surface treatments can be seen in Table 1.
The shear strength of Y-TZP without any treatments is lower (16.39±1.16MPa).

As shown in Scheme 1.
Scheme 1 Synthesis of dinitro I’ and diamine I Polymer synthesis.
The ratio was shown in Table 1.
As shown in Fig.2, the band of 1221 cm-1 was characteristic peak of ether bond, 1157 cm-1 was C-F, 1490 cm-1 was characteristic peak of C-N.

Two ways of increasing area of hydraulic system are shown in figure 1:
Fig. 1 Methods of increasing area of hydraulic system
The relationships among the movement of piston △L, coefficient of thermal expansion a and the change of temperature △T are calculated as follows (the hydraulic system uses the most common one shown in figure 2 ):
S2×△L=V××△T=(S1×L1 +S2×L2)××△T (1)
Fig. 2 Hydraulic system
S1,S2 are the cross-sectional areas of the hydraulic cylinder, and L1,L2 are the length of hydraulic cylinder as shown in figure 2.
From Eq. (1) we have △L= ×△T =△T (2) From Eq. (2) we see when L1,L2 are constant, the movement of piston △L is only related to the ratio of S1,S2.
If we want to move the piston fast we can design S1/S2>1, and then if we want to move the piston slowly we can choose S1/S2<1 or S1=S2.

Raman spectra of the aqueous MEA obtained are presented in Fig 1(a) for the range from 300 cm-1 to 1800 cm-1 and Fig 1(b) from 2700 cm-1 to 3100 cm-1.
Intensity of bands at 417 cm-1, 578 cm-1, 627 cm-1, 750 cm-1 and 1162 cm-1 are found to be not sensitive to MEA concentration, hence these bands are isolated from analysis.
