All three models are validated against experimental data.
HOWEVER, THEY REQUIRE HIGH COMPUTATIONAL CAPABILITIES AND DEPEND ON VALIDATED MATERIAL MODELS BASED ON EXPERIMENTAL DATA.
The latter method is the most time-efficient, but it tends to overestimate the peak mid-height displacement by 10.6% compared to experimental results due to its simplified approach: the method applies a uniform triangular load over a flat segment set without accounting for the angle of incidence or the reductions of the applied pressure due to the curvature of the structure.

(2.4) According to Fig 2.3,make figure of lg[-ln(1-XC)] plotted against lgt (Figure2.4), Obtained from the slope n, obtained from the intercept Zt,then it is available to know non-isothermal crystallization kinetic parameters according to formula 2.4,and obtain half crystallization time t1/2[6], t1/2=(ln2/Zt)1/n, characterize the rate of crystallization during the process of crystallization,as Fig 2.4 shows, all data are presented in Table 2.

Based on the data of Table 2-1 ,conclusion comes out, subjecting to pure PET and nano composite materials with endothermic agent, kinetic rate constant Zc grows up with the increase of cooling rate, while contrastly, the half crystallization time t1/2 reduces, it shows that the higher undercooling rate lead to the faster growth of the crystallization; Under the same cooling rate, Nanocomposite materials with endothermic agent has less Zc than that of pure PET and larger t1/2, the addition of the third component destructed the regularity of the chains, the reduced crystallization ability of molecular chains, making the polymer crystallization rate decreased, crystallization time prolonged.

Various technologies have been used to remove trace lead, namely chemical precipitation, adsorption, ion exchange, reverse osmosis, and oxidation-reduction [6-8].
The data obtained indicates that the polymeric material modified with iron (C100-Fe) exhibits the highest lead removal capacity and can be applied for the efficient removal of lead from drinking water below drinking standard (0.05 mg/L) around 15,000 BVs.
The data obtained indicate that C-100 Fe exhibits the highest lead removal efficiency and lasts for 15000 BVs when compared with the others.

Based on the data of the band structure, DOS (Density of State) and PDOS( Partial Density of States), atomic populations and net charge, the influence on the energy band structure of the macrostructure of ZnO and La-doped ZnO was investigated.
It was assigned to the reduction of energy transfer which was caused by the gathering of rare earth ions in the boundary of grain and also the weak interaction of charge carriers and doping ions due to the lower solubility of rare earth ions in the ZnO materials [8].

Results of the present computations are compared with the available experimental data.
The data used in this study are from the experimental research carried out and given in the reports [17,18].
These values of drag coefficient (CD) were compared with the data given in the report [33].
The validity of these empirical relations beyond this range must be investigated with more data.
The computed results showed reasonable agreement with experimental data.
