As shown in Fig.2, the force which acting on the generating line of half section can be stated as [3] (4) Thus, the curtailment action () can be expressed as (5) Substituting equation (3) and (5) into (2), and solving for limiting bearing capacity which yields (6) Fig.2 Curtailment action of superstratum to external load From equation (6), the conclusion can be achieved that the factors which are related to launching site bearing capacity are mainly include: structure layer material parameters (,,), clay foundation bearing capacity coefficient which is related to internal friction angle (), the thickness of superstratum (), and the radius of rear davits ().

There has been growing interest in spin [9-12] and magnetic field effects (MFE) [13-23] in these materials.
In addition to its potential applications, OMAR poses a significant scientific puzzle since it is, to the best of our knowledge, the only known example of large room temperature magnetoresistance in non-magnetic materials with the exception of narrow-gap high-mobility materials [28].
In intrinsic charge generation, the charges are produced by the dissociation of excitons generated by the photoexcitation in the bulk material without any aid from impurity levels.
The nuclear spin-lattice relaxation time of 13 C and 1H in organic materials can be as large as several minutes [32].

Materials and Methods Adhesive preparation The experimental adhesive consisted of bisphenylglycidyl dimethacrylate (BisGMA) as a monomer, triethyleneglycol dimethacrylate (TEGDMA) as a co-monomer, and silanized barium borosilicate glass with particle size 0.7 micron (V-117-4107) as a filler.
Materials were prepared and handled in an environment devoid of artificial light and were stored in an opaque container at room temperature before testing.
Mixed failure patterns were observed for all materials.
