Ratnam et al. [7] reported earlier that irradiation-induced reactions occur both in double bond and epoxy regions of ENR.
According to Datta et al. [10] and Banik and Bhowmick [11], oxidative crosslinking and chain scission are believed to be prevailing reactions.
According to Ang et al. [15], the irradiation-induced crosslinking in polymers is often reflected by the hardness of the irradiated sample.
This is similar to irradiated ENR50 which have been studied by Ratnam et al. [7] who observed that the hardness of ENR50 was increased with irradiation.

Although the attractive features of S-FEM were previously discussed by applying to crack problems by Fish [3-5], Nakasumi [6] and Okada et al.[7], there are few research about its effectiveness on analysis of the composite delamination problems.

Since the crystallite size of nanocrystalline CoFe2O4 obtained from this study (12-13 nm) was much smaller than that of the critical single domain size of CoFe2O4 nanoparticles reported by Qu et al. [14], at 34 nm, therefore, the magnetic property of the nanocrystalline CoFe2O4 in this study was probably controlled by the numbers of magnetic moments containing in the small nanocrystal (single domain) and the high spin canting and spin disorder occurring at the nanocrystal surface.

The regulation function of choosing resource and its limitation conditions are as follow: res(e) = A ∗ time cost(e) + C ∗ delay(e) (1) B ∗ delay(e) time_cost(e)EL (2) delay(e)

TL EL and DL are their boundary regulation conditions and will have different value in different environments.
