Hysteretic Analysis Model of LRB Nonlinear Simulation for Hysteretic Curve of LRB Many experiments results indicate that load-deformation relationship of LRB is nonlinear, Wen et al [4] presented differential hysteretic resorting force model by lots of research on dynamic hysteretic characteristics of structure, For reducing designing calculation, hysteretic curve of LRB can be simplified to bilinear curve, so equivalent bilinear model of hysteretic characteristics of LRB is established.

Amongst the countable papers in the literature on the study of gas-solid and liquid-solid two-phase flows at the junctions, Morikawa et al. [2,3] reported gas-liquid flows, mainly considering the additional pressure losses across the junction, and Nasr-El-Din et al. [4,5] examined the phase split of liquid-solid flows at T-junction and they found that the phase split greatly depended on branch orientation, particle size and concentration, liquid velocity.
Yang et al. [7] defined separation efficiency to assess the phase separation for T-junctions.
Yang et al. [7] reported that the thicker the water layer, the higher the separation efficiency could be achieved for their vertically upward case.

Fawcett et al [4] synthesized two oxynitrides, SrWO2N and SrMoO2.5N0.5, by the ammonolysis of SrMO4 (M=W, Mo).
El-Himri et al [6] synthesized new vanadium- chromium and chromium-molybdenum oxynitrides by direct ammonolysis of freeze-dried precursors.
Vetter et al found the Cr2N phase when the Cr content (x) in the (Ti, Cr)N coating was >0.1 [10].
This is consistent with the result reported by Lee et al for (Ti1-xCrx) N coatings prepared by ion-plating method [11].

Experimental procedure Experiments were conducted on industrial AZ91 alloy with chemical composition of Al 9.0%, Zn 0.8%, Mn 0.2% wt.%.
Yield point (YP), ultimate tensile strength (UTS) and total elongation (El) were calculated from room temperature tensile tests.

This effect can be ascribed to highly dispersed nano-sized Mg17Al12 phases and higher content of Al element in the solution.

In 1976, Kalinowski et al. reported EL from tetracene crystals [11].
He was the first to report the EL from polymer films.
Bright organic EL at low voltage was first announced by C.W.
